Converting an Internal DVD Drive to External Device

Converting an internal DVD drive to an external device is a relatively simple task for anyone who has a familiarity with basic hand tools.

This project allows a user to add another drive to a small or fully optioned-out computer with no expansion bays remaining or for a desktop CPU that is located under a desk, where opening and closing the drive can be impractical.

This task should take roughly 15 minutes to complete.take” Dell Inspiron 600m CDRW-DVD Combo ” for example:

1、Disassemble the external dvd drive enclosure by removing the screws per the manufacturer’s instructions. (Please note: This step will vary by manufacturer, make and model, but usually requires the removal of four screws from the bottom of the unit.)

2、Lift off the top cover.

3、Attach any mounting brackets to the side of the drive using the retention screws provided. (Please note: Disregard this step if no mounting brackets are required. This is a manufacturer-dependent step and may not apply to your enclosure.)

4、Lower the cable end of the DVDRW drive into the case close enough to connect the cables. (Typically, there will be a data cable, a power cable and an audio cable that need to be connected.)

5、Fit the drive into the base of the enclosure and secure it to the base with the retention screws that were provided with the external enclosure kit.

6、Place the top cover on the enclosure and secure it with the screws that were provided with the enclosure.

7、Connect the drive to your system and power if required.

8、Wait for a New Hardware Found dialogue box to appear. In most installations, this will require you to insert the manufacturer-supplied CD that contains the drivers for the device into your internal CD/DVD rom drive (as the external drive is not functioning yet) and click “OK.”

9、Remove the manufacturer’s driver CD from your internal CD/DVD drive and test your external drive.

How to upgrade your netbook/laptop/pc

Many people admire netbooks for their portability, but no two models are exactly alike, and each reflects different trade-offs. A system with a great laptop battery may have a horrible keyboard arrangement; a model with a solid-state drive might be out of your price range; or a unit with killer specs might be missing 802.11n connectivity. All of these are common problems, but they don’t have common solutions.

Due to their diversity, netbooks don’t share a standard upgrade path as typical desktop PCs do. Each model is unique in what you can do to it, and the procedures are as varied as the netbooks themselves. If you plan to upgrade your machine, you’ll need to hunt down the instruction manual or – in the case of trickier upgrades – a community of users to walk you through the process. That said, possible netbook hacks range from five-minute routines to soldering-gun-based surgeries. Following are seven hacks for a Dell e1505 – one of the more tweakable netbooks we’ve come across. The first three hacks are easy, and the other four are intermediate. While your mileage (and procedures) will depend on your own netbook model, this guide should give you a good idea of the kinds of upgrades that are available (and suitable) for your machine and your skill level.

1. Insert a better battery

In PC World testing the Dell Inspiron E1505 Battery survived for about 3 hours, 34 minutes. That’s not too shabby for a four-cell battery, but you can do better. Though you may find a few guides online that describe how to create a laptop battery by using a number of aftermarket batteries wired together, that method is a recipe for disaster

Dell Inspiron E1505 Battery 9 cells 6600MAH

Instead, we found an Nine-cell, 6600mAh battery on that’s entirely compatible with the existing connections (and size) of your Dell e1505. At $191 it’s by no means cheap, and if you’re prepared to order offshore you can do a lot better with a US$69.99 battery from, who ship worldwide. With an nine-cell battery you’ll double the longevity of your netbook – provided that you aren’t bothered by the inelegant mass sticking out from underneath it. To replace the laptop batteries, just flip your netbook upside-down, move the two switches from the locked icon to the unlocked icon, and then push up on the battery tray.

2. Upgrade the OS

If you want to install a new operating system onto your netbook, you certainly can: you simply pop the CD/DVD into any external USB optical drive and install away.

Want to dual-boot your netbook? Grab the GParted utility, by downloading the .iso file for its LiveCD at and then burning the file onto a disc. Insert that disc into the external optical drive, restart the netbook, and enter the BIOS to change the boot settings for your machine. Boot off of the optical CD/DVD drive first, and GParted will load. Right-click on the primary partition and select Resize/Move. Microsoft recommends that you have at least 16GB of space for Windows 7; if you were hoping to use that OS but your netbook has too little room, your experiment ends here. For any OS, if your netbook does have space for it, enter a new partition size of your choosing. Click Resize, and you’ll see the newly unallocated space sitting to the right of your primary partition in GParted’s graphic. Right-click on this area and select New. Enter zeros for ‘Free Space Proceeding’ and ‘Following’, select Primary Partition under ‘Create as’, and click the add button.

If you prefer not to use an external optical drive, you can follow the same steps for using GParted and installing the new OS with a simple USB thumb drive.

3. Rearrange the keyboard

Does your laptop keyboard’s default layout conflict with the muscle memory you’ve built for desktop keyboard layouts? You can pop an offending key off of your netbook by wedging a tiny screwdriver under the key and gently applying upward pressure. As long as the keys you are swapping are the same size, you can interchange them as you please.

Dell Inspiron E1505 Keyboard

Once you’ve made the physical transformations, use the Sharp Keys utility ( to reassign your OS’s interpretations of the keystrokes to the appropriate keys. Alternatively, if you don’t mind a bit of visual confusion, you can leave the physical keys exactly where they are and use this helpful application to redefine their purpose.

4. Replace the hard drive

What’s worse: the underwhelming capacity of a typical solid-state drive inside a brand-new netbook, or the price difference you’d have to pay to get a larger drive in your preconfigured netbook build? Here’s a way around both of those nightmares. First, when you’re building your netbook on the maker’s website, select the lowest-capacity drive available (or if you have no configuration options, buy the netbook as is). Next, consult user forums (see “More resources” on page 85) to get a clearer sense of which aftermarket solid-state or magnetic hard drives are compatible with your unit. Finally, grab a screwdriver.

For the Dell e1505, flip the netbook over and remove the two screws that secure the large back panel into place (since it’s in the centre, it’s hard to miss). Pry off the panel with your finger or with the tip of a screwdriver. With the Dell e1505 battery facing north, you’ll notice a set of four electronic pieces inside the machine; those are the hard drive, the memory, the network card, and a space for a 3G card (if you bought your e1505 from Vodafone it will have the 3G card installed). You should see a pair of screws securing the tiny flash-memory circuit board into place in the upper-left quadrant. Unscrew them, and the SSD should lift up. Pull it out, insert its replacement, and tighten the screws.

5. Upgrade the RAM

Memory is one of the main areas of a netbook where system manufacturers can increase their profit margin. Don’t let a netbook maker empty your wallet by selling you RAM that you can find elsewhere for a lot less. In the case of the Dell e1505, we bought the bare minimum of RAM that we needed to complete the configuration: 512MB. To upgrade RAM, first open the netbook’s back and look for the existing memory. On the e1505, it’s in the upper-right (with the battery facing north).

On the RAM module you should see its specifications. You can either purchase the same type of RAM in a larger size (in our case, a 2GB stick of DDR2 SODIMM running at 533MHz) or check the manufacturer specs for your netbook to discover its maximum supported speed. The difference between DDR2-4200 and DDR2-5300 memory is almost unnoticeable, but there’s no sense in maxing out with DDR2-6400 memory if your netbook can’t support its full speed.

To replace the memory, push outward on the two clips holding the RAM in place near the notched groove on each side. The RAM will pop up toward you for removal. Insert the new memory and push it into place. When you start up the machine, quickly press the appropriate key to access the system BIOS (for the Dell Mini 9, it’s the 2 key). Head to the main tab and confirm that the system recognises the new memory.

6. Upgrade the Wi-Fi

Upgrading the internal Wi-Fi capabilities of a netbook from 802.11g to 802.11n sounds as though it should be easy. In theory, you’d simply buy some laptop accessories such as a miniature wireless card, pop off the back of the netbook, shuffle its components, and start enjoying the increased functionality and speed of the new card.

Alas, in reality it isn’t that simple. Just because a Wi-Fi card looks as if it will fit in your netbook, that doesn’t mean the card is compatible with the netbook’s OS/motherboard combination. But even before that, you have to deal with the issue of size. When purchasing a new Wi-Fi card, you need to know whether your netbook can support a full-height or half-height card. Remove the back of the netbook and look for the existing Wi-Fi card. A full-height card is long and rectangular, similar in shape to an SD Card for a camera. A half-height card is stubbier and resembles the shape of a CompactFlash card.

As for the particular brand of card, there is no hard-and-fast rule for determining what will be compatible with your netbook model. A card that looks perfect on paper may not work with your unit’s configuration. Instead of using trial and error, search the internet for stories of other people’s successful Wi-Fi upgrades of the same netbook model. It’s the best way of improving the odds that the card you pick will actually work.

Once you’ve cleared that hurdle, installing the card is easy. On the Dell e1505, for example, remove the netbook’s rear cover. The Wi-Fi card is in the centre-right of the system; it’s the card with white and black wires (the antenna) running into it. Gently disconnect those wires, undo the screws, and remove the card from the slot. Insert the new card, reinsert the screws to tighten the card into position, and reconnect the two antenna wires – note, however, that the specific card you buy will dictate whether you should reverse the wires as compared with their positions on the original card. Depending on the size of the card and the configuration of the motherboard, you might have to remove a motherboard standoff to permit a solid fit.

If the operating system can’t find the new card on the next boot, install the drivers for the particular Wi-Fi card you bought. You should be able to find the drivers on the company’s website; if not, you might have to install drivers from a third-party netbook manufacturer whose product uses the same network card.

7. Overclock the CPU

Overclocking represents the pinnacle of system upgrades that an average user can perform without physically deconstructing the netbook. It’s also among the more dangerous upgrades for netbooks, given that these miniature systems don’t come with the best cooling systems. In the case of the Dell e1505, the passive cooler protecting the processor from thermal overload is no match for frequency tweaking, and it’s probably for the best that we couldn’t find a way to overclock this tiny PC.

Other netbooks are a bit more flexible in this regard. Owners of Dell e1505 netbooks can rev up their CPU through the SetFSB utility. Users of earlier Asus Eee PC models can pick up the Eeectl utility, which permits them to alter the frontside bus within Windows and, consequently, up the speed of the processor. If you have an MSI Wind and you want to update its BIOS, you’ll discover that MSI officially supports your overclocking habit. Still, these waters demand careful navigation (or strict avoidance) lest you wreck your netbook and condemn it to an inglorious end.

Increase the capacity (runtime) of your laptop battery

Is your laptop battery dead?
Is the runtime not long enough to get you through the day?
Do you carry one of those huge external battery packs?

Take “hp dv8000 battery” for example,This instructable is intended to show how one may replace the dead li-ion/li-poly cells of a dv battery and how one may increase the capacity of the battery by adding extra cells.

The reason why adding extra cells to the internal battery is suggested compared to carrying around an external battery pack is that for the same amount of cells in an external pack, the laptop accessories can run significantly longer if those cells were used internally.

hp dv8000 battery

HP Pavilion dv8000 Battery 8 cells 4400mAh

1、External battery pack? Rip it apart and never think of using an external pack again

So what’s the voltage rating on your internal battery pack?What’s the rating on your power brick?Lets use my tablet computer as an example. The battery pack is rated for 3.7v * 3 cells or about 11volts. However, the power brick outputs 20v.I’ve bought external battery packs before and have calcul…

2、How laptop batteries work

Laptop batteries are complicated pieces of equipment. They are somewhat redundant as well. There’s a ’smart circuit’ in the battery pack that monitors the conditions of the battery cells, however, it does not do what a lot of people say it does. The image below is a typical smart circuit. It ha…

Safety preparations -put sand in can (picture below) -place fire extinguisher someplace close Battery preparations -if you’re just replacing your dead cells with new ones, obtain the same number of cells. As for choosing the capacity, bigger is better. -Note how the cells are connected in seri…

5、Safety first: test the darn thing

I’ve seen some people who’ve posted how-to’s for replacing laptop cells immediately replace the cells seal the battery and use it. This is extremely dangerous, unless you want to cook your lap. The quality of the cells purchased is unknown, and needs to be tested. (manufacturers of laptop batteri…


-If your battery doesn’t explode/catch on fire, that means the circuit is good/the cells are good. -Solder it permanently to to the circuit, and fit it back into the plastic housing if its the same number of cells, if not be creative and line the cells up so it fits nicely below/behind/etc your l…

DvD Drive Can not Write to Writable Discs (Windows 98, ME, XP)

I got hp pavilion dv6000 laptop, problem is it is not writing dvd’s.. My dvd drive has stopped reading and writing dvds though it is reading cds. I have tried to uninstall and reboot several times. it’s out of warranty now. is there any way to correct it.


Use the steps in this document to troubleshoot problems that can occur while trying to burn discs with a recordable CD or DVD drive. Start at Step 1, do not skip to other sections until Step 1 has been completed.

Step 1: Identifying the drive in Device Manager

Use the following steps to determine if the drive is being properly recognized by Windows and to find important information about your drive:

1.In Windows XP, click Start , and right-click My Computer .
In Windows 98 and Me, right-click My Computer .

2.In Windows 98 and Me, select Properties , and click the Device Manager tab.

In Windows XP, select Properties , click the Hardware tab, and then click the Device Manager button.

3.Click the plus sign (+ ) next to DVD/CD-ROM Drives (or similar) category.

Figure 1: Drive device name in Device Manager

4.If the CD or DVD drive is not showing up in Device Manager, close Device Manager and use the support document CD or DVD Drive is not Detected .

If the name of a CD or DVDRW drive is listed but is listed as “CD-ROM”, skip to Step 4 to set the drive as a recordable drive.

If the name of a CD or DVD drive is listed, write down the name of the drive and continue to step 2.

NOTE: If the drive name contains an error (a yellow triangle or a question mark), double-click the drive name to read the error message. You can then use this information to search for more troubleshooting information in the event the rest of these steps do not help.

Step 2: Ensuring your system is compatible with the CD/DVD media

Read and understand each of the following items before attempting to troubleshoot further:

*You cannot burn DVDs with the Windows XP disc burning process. At the time of this writing Windows XP only supports CD burning, not DVD burning. To burn DVDs in Windows XP you must use separate software – such as RecordNow or Creator Basic. Please continue using this document if you are having problems burning DVDs with special software.

26.99 USD -HP Mini-2133 USB CDRW Black 24X :

* Make sure your drive is actually capable of burning to the type of media that you want to use. For example, a combination DVD/CDRW drive cannot burn DVDs. Eject the drive door and look at the front of the drive to view all the various formats that the drive is capable of using.

*If the drive is having problems burning discs that you know are compatible with the drive, either the disc is bad or the drive’s firmware may be able to be updated. Updating the drive’s firmware may make the drive compatible with more brands of discs. Updating the drive’s firmware does not enable the drive to burn a new type of disc. For example, you cannot update the firmware of a CD-R/RW drive so that it can burn to DVD+R or Dual-Layer discs.

If you want to update your drive’s firmware or you are still not sure if the drive supports the disc you want to burn, please refer to the support document Identifying the Preinstalled CD or DVD Drive .

*If your drive is not burning or recognizing any discs, use quality CD-R discs for testing purposes as CD-R is highly compatible.

*Dual-Layer discs can only be burned by DL compatible drives. To check, open the drive door and look for a “DL” printed on the front of the drive.

*Blu-ray discs can only be burned by BD compatible drives and requires special software to burn. To check, open the drive door and look for a “BD” printed on the front of the drive.

After checking each of these items, continue to Step 3.

Step 3: Decreasing the burn speed

If the drive is not recognizing the disc at all, skip to Step 4. Decrease the CD writer’s burn speed by half to increase the likelihood of a successful burn. Decreasing the burn speed is a quick, easy way of increasing successful disc burning sessions, at the expense of taking more time to create a disc. The following steps are for Windows XP only. For Windows 98 and Me, decrease the write speed from within the software that you are using to write discs (RecordNow, Easy CD Creator)

1.Click Start , and then My Computer .

2.Right-click the drive icon, and select Properties .

3.Select the Recording tab and reduce the Current Write Speed by half (for example, from 16x to 8x).

4.Click OK and close the My Computer window.

Try burning a CD. If the drive fails to create the CD, go to the next step.

Step 4: Setting up disc recording in Windows XP

If the computer does not have Windows XP, skip to Step 6.
If you are using Windows XP, use the following steps to ensure that native burning is enabled:

1.Place a blank disc into the drive.

NOTE: If the error is not accessible. Incorrect function. ” opens, close it and continue using these steps to correct this problem.

2.Click Start , and then My Computer .

3.Right-click the writable drive icon, and select Properties .

4.If a Recording tab is shown, select the Recording tab, select Enable CD recording on this drive , and then click OK . Try burning a disc again. Continue to the next Step if you are unable to burn a disc.
If a recording tab is not shown, continue using these steps.

Figure 2: Enable CD recording on this drive

5.Look for a Recording tab:

If the Recording tab is not shown, Windows XP has not detected the drive as a recordable device. Use the following sub steps to enable the Recording tab:

1.Click the following Microsoft Fix it Solution to clean the registry filters automatically:

If you cannot use the Microsoft Fix it Solution, continue using these steps to clear the upper and lower registry filters manually.

2.Click Start , Run , and type regedit in the Open field.

3.Backup the registry: Select My Computer from the list, click File , Export , type a name that you will remember, and click Save .

4.Click OK , and browse to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CD Burning\Drives

5.Click the Volume key that matches the CD/DVD ROM drive that is capable of writing discs. If only one drive is installed, one volume key is listed. If you have more than one drive, examine the data values (by double-clicking them in the right pane) to find the correct drive.

6.With the volume key selected in the left pane, double-click the Drive Type value in the right-pane.

Figure 3: Drive Type registry value (CDRW)

7.Type the number 1 in the Value Data field if the drive is capable of recording to CDRW discs (including CD-R discs). Type a 2 if the drive cannot write to CDRW discs but can burn CD-R discs.

NOTE: A value of 3 indicates that the drive is only capable of reading discs. Changing this value to a 1 or 2 enables Windows to view the drive as a recordable drive.

8.Click OK , and close Registry Editor.

9.Repeat the steps in this section, starting with step “b”.
NOTE: For more information about enabling the Drive Recording tab, please refer to Microsoft support article 316529 CD-R drive or CD-RW drive is not recognized as a recordable device (in English).

Step 5: Resetting the drive in Windows

Use the following steps to replace the drive settings in Windows.

1.Remove the drive from Device Manager :

1.Open Device Manager and select the CD Drive name.

2.Click the Uninstall or Remove button (in Windows XP this is the square button with a red X).

3.Click Yes or OK to remove the CD listing. Do not restart the computer.

4.Close Device Manager .

5.If your computer has Windows XP or 2000, go to the next step without restarting the computer .

If your computer has Windows 98 or Me, restart the computer, wait until all “New Hardware” messages have resolved, and then try burning a disc. If problems persist, skip to Step 6 .

2.Clear the registry filters (for Windows XP only):

1.Click Start , Run , and type the following into the Open field: regedit

2.Click OK . The registry editor appears.

3.In Windows XP, click File , Export , type a filename that is easy for you to remember, and click Save .
A copy of the registry has been saved for back-up purposes. You can double-click the export file to restore the registry in the event of a problem.

4.Click the plus sign (+ ) next to the following items in the listed order:

* CurrentControlSet (or the current control set with lowest number if that is all that is listed)
* Control
* Class

Figure 4: Delete: LowerFilters value

5.Select 4D36E965-E325-11CE-BFC1-08002BE10318 .

6.Select UpperFilter in the right window and press the Delete key.
Confirm the deletion by clicking Yes .

7.Select LowerFilters in the right window and press the Delete key.
Confirm the deletion by clicking Yes .

8.Close the registry editor, restart the computer , and wait until Windows configures the necessary drivers for new hardware.

9.After Windows is done configuring the new hardware, uninstall all CD writing software (RecordNow, EZ CD Creator) using add/remove programs.

CAUTION: Make sure you understand how to install your burning software before uninstalling it. HP disc burning software can be reinstalled through the application recovery process.

10. After all CD writing software has been removed, restart the computer and then reinstall the CD writing software using the HP or Compaq application recovery software or by using Compaq’s quick restore.

11.Try burning a disc. If you still cannot create a disc, go to the next step.

Step 6: Using Microsoft System Restore

If the computer still cannot write to the disc, use System Restore to go back to a time when the drive was recognized by Windows. This step is only for Windows Me and XP. If you do not know how to restore Windows, use the Support document ” Using Microsoft’s System Restore Feature .”

When done, try burning a disc again to see if it works. If it works, you are done. If it does not, go to the next step.

Step 7: Using HP System Recovery

If the computer still cannot write to the disc, recover the computer. If you do not know how to recover the computer, use one of the following documents:

*Pavilion: Running a System Recovery in Windows 98 and Me

*HP and Compaq Desktop PCs: Performing a System Recovery in Windows XP

* If the Presario computer came with quick restore discs, insert the first disc into the top CDRW drive or DVD drive, restart the computer, and follow the onscreen instructions.

When done, try burning a disc again to see if it works. If it works, you are done. If it does not, go to the next step.

Step 8: Determining if the drive hardware is bad

If the computer still cannot write to the disc, open PC Doctor to gather more information and respond accordingly (not on Presario units manufactured before 2000).

1.Click Start , Run , and type the following into the Open field: pcdrw32

2.Click OK and wait for the PC Doctor window to appear.

3.Open the appropriate CD/DVD-ROM test from the list of tests (as in the column to the left of the first menu).

4.If an error code is reported, the computer may need to be serviced. Run the test again to confirm the error code. Use the following support document if you need more information: Using PC Doctor

5.If, after you have tried all these steps, the drive still cannot write to recordable discs, the drive is probably bad and should be replaced.

Dell Inspiron 6000 battery won’t charge and AC adaptor not recognized

I have a Dell Inspiron 6000 that just turned two years old.

After one year, my dell 6-cell battery started to falter, so I purchased a new 9-cell battery. This worked fine until a couple of months ago when I noticed that my 65W adaptor was frayed. I bought a new 65W Dell Inspiron 6000 ac adapter and it worked well for about a week until I noticed that my battery wasn’t charging at times. If I was patient, or unplugged the adapter and plugged it back in, the battery began charging and all was saved.

Dell Inspiron 6000 laptopThis lasted only a short time until my Dell Inspiron 6000 battery wouldn’t charge at all for long periods of time, and sometimes the computer wouldn’t turn on, even if plugged into the wall. I thought it might still be the adaptor, so I borrowed a fully functioning 90W Dell adapter from a family member to test the system. This worked better, but still not great. When I removed the battery and started only from AC power, the functionality was also intermittent. Usually, if the computer actually started, I received the start-up error “The Inspiron 6000 AC Adapter Type could not be determined, etc. etc. etc.” After pressing F1, the computer booted, but if the battery wasn’t in, the computer didn’t usually last long before shutting off. Unsure if maybe the battery was the problem, I put the 6-cell Inspiron 6000 battery back in, and it too wouldn’t charge, although (together with the 90W adapter) my computer would at least start more consistently if plugged in. The error remained however, and sometimes the system stops recognizing power and switches to my ever dwindling battery power until the adapter is recognized again.

The problem is with the jack on the motherboard inside our Inspiron 6000’s. This is the jack you plug your power plug into on the back of the laptop.

Somehow the jack gets worn and does not make correct contact with the laptop so the Laptop does not see the power supply as a legit Dell brand. So the powersupply will not charge the laptop battery and run the laptop at the same time.

DC power jack repair guide. Do-it-yourself instructions.

Modern laptops are all sold with built-in wireless laptop ac adapter. Some power notebooks used by corporate road warriors will have powerful cellular adapters that connect the laptop to the Internet via the cell phone infrastructure

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with dell pa 12,dell e1505 and Dell Inspiron 6000 notebooks. If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it’s still under warranty, it would be fixed at no charge to you. Problem symptoms:

  • Laptop randomly shuts down without any warning.
  • Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  • The battery will not get charged.
  • When you plug ac adapter for laptop, the laptop appears to be dead and there is no LED * activity at all (DC-IN jack on the system board is broken).

To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. dell pa 12 and Dell Inspiron 6000 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system laptop board with a magnifying glass. In most cases you get the power problem because of a bad connection between the DC jack and the system board, you’ll see a crack between the DC jack connector and the system board.

HP PAillion dv8000 PC Notebook will not charge

Question:For awhile if we jiggled the power cord it would charge but now HP dv8000 won’t even work!! Any ideas of what could be wrong I would really appreciate it.. I was thinking it probably was a bad power cord….


There are a number of other maintenance actions you can perform that can alleviate HP Pavilion dv8000 AC Adapter problem. You can toggle the voltage switch between 115V to 230V and reset to the proper voltage for your geographic region.

You can open the case to check the connection between the incoming cord and motherboard and use a vacuum to remove any impeding dust. You can plug the HP dv8000 AC Adapter into a different wall outlet or power strip to check for problems in those external sockets.

Short circuits are caused by physical or electrical damage and can drain available power, preventing proper function of your HP dv8000 Adapter. If the ac adapter turns on when you plug it into the wall only but turns off when you also plug it into the laptop, you may be looking at a short circuit.

If your ohmmeter gives a reading of less than 3 ohms at the point where the ac adapter for laptop plugs into the HP laptop, this is an indicator of a short circuit. You can find the location of the short by examining removable laptop components, such as HP dv000 Battery, Zip drives and other USB components. If necessary, you may need to be crack open the laptop to check interior components, including the motherboard, for burn marks. You should replace the affected part.

If the LED light is off when your AC Adapter is plugged only into the wall but turns on when you plug it into the hp pavilion dv8000 laptop and the wall, this can indicate a power overload. Remedy this by checking th outlet,unplugging/replugging connections on either end and then removing the plug from the laptop. If the light is still off, the HP AC adapter may be fried. Also, you should plug in the laptop ac adapter while the laptop battery is removed to check the viability of the power supply.

Most HP ac adapters consist of a small box with wires on either side connecting to the laptop and a wall socket, as well as an LED light showing if the laptop ac adapter is on/off. The most common issues encountered by users involve the LED light not turning on, short circuits and power overloads.

How do I replace keyboard on a dell 15?

It’s easy to break the flimsy keys on most laptops. Sometimes it’s cheaper to find a laptop keyboard for your model laptop elsewhere than going through the manufacture. If you find yourself in this situation, you can use these steps to replace the keyboard. take “Dell Inspiron E1505 Keyboard” for example:

Dell Inspiron E1505 Keyboard US

Dell Inspiron E1505 Keyboard US

Removing the Damaged Keyboard…

Enusre the laptop is fully powered off, unplugged from the wall, and the laptop battery taken out.

Turn the laptop over. On some models icons indicating which screws are attached to the keyboard are displayed. If not, you may have to “eyeball” it if you can’t find a breakdown for your model (such as dell pa 12 or pa 10)online.

Remove those screws with a T-8 or Phillips screwdriver.

Turn the laptop back over and open it up. Check and see if the keyboard is tucked under any plastic pieces. If so, find if those plastic pieces are screwed into anything, and unfasten them as well. If not, it probably uses clamps that can easily be removed.

Remove the plastic pieces carefully with a toothpick or plastic pick if there is any in the way.

Unscrew any screws at the top (if necessary) and remove the keyboard itself from top to bottom. You’ll notice that the keyboard is connected with a thin, but wide, data cable to the system board at the bottom.

Take that same pick and lift the plastic connectors that hold in this data cable in place.

carefully remove the data cable. Now the whole keyboard should be free.

Replacing the keyboard.

Take the new laptop replacement keyboard out of the plastic, and slip the data cable back in between the plastic connectors on the system board. Make sure it’s all the way in.

Use the pick to push the plastic connectors back into place, and make sure it’s holding the data cable in.
Slip the keyboard itself into place, from bottom to top. Make sure the screw holes or clamps line up at the top.

Refasten the keyboard in place at the top.

If you had to remove any plastic pieces, carefully snap them back in and replace any screws you had to remove.

Turn the laptop over and replace all of the keyboard screws.

Finally, put the battery back in and power on the laptop. If all has gone well, the keyboard should be functioning like brand new.

How to Charge a Car Battery Using a Battery Charger

If you find yourself with a dead battery in your car and have access to a battery charger you are only some time away from being on the road again. Whether you are using a small car charger known as a trickle charger or a larger unit on wheels, you can charge your battery effectively. There are safety concerns though. Be sure to check the warnings

1、Locate the battery or remote charging point by consulting the owner’s manual. You can also open the hood to find the battery. The laptop battery may be under a seat, in which case a charging point may be provided under the hood.

2、Remove any plastic covers that may be protecting the positive and negative posts of the battery. Just push the covers to the side as they are usually pliable. Note the location of positive and negative terminals signified by a plus and a minus sign respectively.

3、Locate the laptop car charger so that its cables will reach the battery. Make sure your charger will reach an electrical outlet. Add an extension cord if needed.

4、Place the clamps of the charger on the battery making sure that the red handled clamp goes to the positive battery post and the black handled clamp goes to the negative laptop batteries post. If you are not sure, trace the cable attached to the clamp back to the charger and look for a positive or negative designation. If you are still not sure, stop and seek professional advice.

5、Plug the charger in, making sure that the selection switch is set to off.

6、Select the appropriate voltage and or rate (almost all cars have a 12 volt system). If time permits choose the slower rate and plan on charging the battery for two hours. This selection will turn the charger on. If the charger has a timer, set it.

7、After charging the battery, unplug the charger, disconnect the charger’s cables and start the car.

Looking for the longest battery life laptop ?

how to maintain compaq 6715b to get better battetry backup for more than 2 hours? How to get more from a laptop battery?How to extend laptop battery life?Looking for the longest battery life laptop ? now,we take” compaq 6715b battery “for example:

1. Turn off Wi-Fi and BlueTooth – Most laptops have shortcut keys to instantly disable wireless networking.

2. Don’t play computer games, music or DVD movies – Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness – Dimming your display saves notebook battery power.

5. Tweak Windows Power Options – Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use.

10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

Looking for the longest battery life laptop ?

Actually, many factors affect the amount of time that a laptop 6715B battery can deliver power before it must be recharged.

How to extend laptop battery life?

Take “hp dv8000 battery” for example,Here are some more tips to improve your notebook’s battery life:

1. If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.

2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can’t create as much power.

3. Make sure to plug your laptop ac adapter into a UPS and not directly into a power outlet or surge protector.

4. If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.

5. Fully charge new dv8000 battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.

6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.

7. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

Battery-saving sleep modes: Should I use Stand By or Hibernate

Standby mode

Use standby to save power when you will be away from the computer for a short time while working – your monitor and hard disks turn off, all applications and open files are stored in RAM. When you want to use the computer again, it comes out of standby quickly, and your desktop is restored exactly as you left it.

Hibernation Mode

Use hibernation to save power when you will be away from the computer for an extended time while working – your computer shuts down to save power but first saves everything in memory on your hard disk. When you restart the computer, your desktop is restored exactly as you left it.

When you choose Start, Turn Off Computer in Windows XP, your options are Stand By, Turn Off, and Restart. To Hibernate, place the cursor over Stand By, then hold down Shift and click.

How to Clean a Dell Inspiron Keyboard

Dell notebooks are portable devices that can be carried everywhere and used in all kinds of settings. Their keyboard tend to accumulate dirt and grime over time. A regular cleaning would be the first step to preventing keys from getting stuck or repeatedly typing the same letters. It would also prolong the life of your Dell Inspiron notebook(such as inspiron 1525).

Maintenance is one cost-cutting measure that could save you unnecessary future repairs. take “Dell Inspiron 6000 Keyboard” for example:

$17.99 -Dell Inspiron 6000 Keyboardat

1.Lift the right corner of your notebook’s hinge cover using a flat-blade screwdriver.Pry it loose from the notebook’s base.

2、Remove the laptop keyboard by unscrewing the two M2.5 x 5 mm screws located atop your keyboard. Fragile keycaps can easily be dislodged but are difficult to replace, so exercise care.

3、Rotate the laptop replacement keyboard slowly up and forward toward your display screen. You will see the keyboard connector below it. This has a delicate ribbon cable with a plastic bar.

4、Release the laptop keyboard cable from its attachment to the keyboard connector.

5、Rotate the plastic bar of the laptop keyboard connector forward toward the front of your display.

6、Detach the entire laptop keyboard from the notebook’s base.

7、Spray compressed air lightly on your laptop keyboard to loosen debris from keys.

8、Wipe gently but thoroughly in between key slots and all plastic portions using a cotton swab dipped in rubbing alcohol. Avoid dampening any wire connections.

9、Reattach the whole laptop keyboard after cleaning. Hook the tabs on the lower portion near the palm rest and gently press the right upper portion of your keyboard to snap it back into place. Firmly replace the two screws using the screwdriver.

Having Problems with your HP Pavilion dv6000 Notebook?

HP announced that there may be hardware issues with some (not all) with their HP Pavilion dv6000 and dv9000, and their Compaq v6000 series notebooks at 2007. The symptoms that may occur were these:

* The notebook does not detect wireless networks and the wireless adapter is not detected in the Device Manager.
* The notebook has no power and no active LEDs.
* The notebook does not start.
* The dv6000 battery charge indicator light does not turn on when the battery is installed and the AC adapter is connected.
* The notebook issues a single beep during boot indicating no power.
* There is no video on the computer LCD panel or external monitor.
* The external monitor functions but there is no image on the notebook LCD panel.

If your Notebook was affected by any of these issues, and qualifies, HP would fix it for free (including shipping charges to and from them). If your warranty wsa over, they would still fix it if it was within 1 year of the end of your warranty, they would also give you a 90-day warranty on the repair. If you warranty was still in effect, it would remain unchanged.

Full details, instructions for checking your BIOS version and updating it (if needed) and an FAQ can be found here. Please note, that this problem does not affect all notebooks within the model and serial number range.

I think it’s pretty cool of HP to fix affected notebooks even if they’re out of warranty.

There’s also a critical BIOS update that you should do (regardless of if your notebook is affected by these problems or not). Also, before sending your notebook into HP, be sure to backup all your data, as they’ll probably reset your laptop to the factory state (ie. all your data and programs gone, Vista fresh, and bloated with bloat-ware).

This actually happened to my sister’s laptop (hp pavilion dv6000), on either Friday or Saturday last week, the Wireless Adaptor stopped working. Windows could not find any networks, and the Wireless Adaptor was not showing up in the Device Manager. So, I tried reinstalling the Device Driver, but that didn’t fix it. So, I tried updating the BIOS to the latest version, and that failed to work too. I even opened up the HP Wireless Assistant, and even that didn’t see the dv6000 ac adapter. I had determined that the Wireless Adaptor was not working because of hardware problems. So, I shot an email to HP, and they told me to do what I had done already (except, they also wanted me to recover the laptop to factory state, I didn’t want to do that), and said that if the problem persisted after trying those steps, to phone HP Technical Support and explain the problem to them. I decided to try Live Chat first. I explained the problem, and what I did to troubleshoot and attempt to fix it. They were ready to setup the warranty service, but then they realize that the model in question was a Canadian model, and that I would have to phone HP Technical Support.

So, yesterday I phoned them up, and got through to somebody in about 5 minutes. I explained the problem to the guy who answered (who actually spoke English!!!) and what I did to troubleshoot it and attempt to fix it. He had me hard reset the notebook, which didn’t fix it. So, he had me plug an Ethernet cable into the notebook, to check if that worked (which I had done when the problem started, but forgot to mention it to the guy). Then, he had me power cycle my Internet Modem,checked hp dv6000 ac adapter (apparently, I also forgot to mention that the problem wasn’t with my Wireless Network, as my notebook connects to it fine). Then, he put me on hold for 5 minutes, and came back on the phone and told me that it’ll need to be sent into HP for warranty service. He explained to me that HP will send me a box through FedEx, which contains instructions, and that I should pack the notebook into the box (duh), and either get FedEx to pick it up, or to drop it off to FedEx. He said the box should arrive on Saturday (tomorrow), and that it usually takes 7-10 business days for you to get your notebook back (article on HP’s site says 10-14…). But, since Christmas is coming up soon, it might take longer. And… well, that was it, the warranty service was arranged, and all I need to do is put it in the box, and hand it over to FedEx. Pretty simple.

my dell pa 12 won’t start ?

When i start my dell pa 12 up and it takes 10 mins to load to windows XP, , when the windows loading screen comes up the FANS go crazy. I then wait till i’m at the desktop at which point i immediately shut down the pa 12(which takes a further 7 mins) while the FANs are going crazy.

Now if i start the pa 12 again it works normally.

I had to do this procedure everyday, untill today when i switched the pa 12 on, waited till the desktop appaered and i removed the battery while the pa 12 was on..

Dell PA-12 AC Adapter

Now when i switch the pa 12 on it powers up but i’m not getting anything on the screen

First try a different AC adapter (such as :pa 10 ac adapter)

If no change then the issue is the motherboard. Often the AC adapter will fail then the battery discharges and you get the symptoms you describe.
SO AC adapter then MB

It shows no power on your laptop but it shows you the dvd player led comes on then off. I would suggest try the following:

1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Press and hold on the laptop’s power button for 10 seconds to drain the power flea.

3. Connect the AC Adapter to a known good power outlet, check AC Adapter power LED if it is on. Try to sense if AC Adapter is not making a bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter (hp dv6000 ac adapter)to the laptop. Check if AC Adapter LED stays on when it is connected to the laptop. If the LED stays on means the AC Adapter is fine. If the AC Adapter LED turned off check the AC Adapter pin that goes to the laptop AC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try to power on laptop. If no power LED comes on then this is motherboard problem.

6. Before replacing the motherboard there is one checking needs to do. If you can open your laptop bottom part then good, do this when laptop is not connected to any power source. Try to reseat the laptop CMOS battery then try to power on laptop after, if still fails then replace motherboard. I hope this helps.

hp pavillion dv6000 battery not charging

I noticed that my laptop power stayed at 6% even though I was on power for over two hours. I checked and noticed this…plugged in, not charging. how should I do?


1) Powering down the laptop.
2) Remove battery and dv6000 ac adapter
3) Wait a few minutes.
4) Plug power back in and then plug back in battery.
5) See if charger light (blue light in front) comes back on.

If not re-try this.

When charger light comes on, then power up laptop and check for charging.

This had to be done for me with laptop powered off.

Also, if you get it fixed and dv6000 battery charged, remove battery after powered down
as it seems to discharge after not using, more than it should for being idle!

The correct solution is not buy an HP notebook computer. I have been traveling for work with a computer for almost 20 years now. I have carried a lot of different brands of computers. I have never had a battery last just 1 year UNTIL now. And to add to the insult this computer is one used almost exclusively by my wife who only takes it to her business and home, not in an airplane. So it has been well taken care of. I just called HP – no go on any help from them.

My solution – no more HP computers for my family and I can no longer recommend their brand of laptop. This one will be replaced within the next 12 months.

Two possible problems for this -DC JACK Issue

1: one side of the DC ground is not conntected to the rest of the system, so no circuit is complete to the charging section.

CHARGING Circuit issue

2: bad power controller chip (MAXIM IC) or zener diode in that circuit, maybe bad

Any one with a HP Pavillion 6000 series, who is having certain tech difficulties should go to HP page and search for extended service warranties to see if your system qualifies. I had an issue with my wireless driver and all I had do was to first turn your system completly OFF, then remove the battery, then remove the middle cover (underneath Lap Top) and then remove the wireless card. (You will see it connected to two small cables) remove the cables and the small screws and remove the card and then reinserted the card and close the cover -do remember where the two cables go- . Then turn on your system, -do not put the battery yet- and go to control panel/ device manager/ look for hp dv6000 ac adapter, and see if you see your lan card, once this is done reconnect your battery. If you don’t then contact HP they will fix it for free, even if your warranty expire. They will even pick up your postage!.

If your HP Pavillion dv6000 has a battery that won’t charge yet still turns on when plugged in, turn off the laptop and remove the battery then wait for around 30 seconds, re-insert it and turn it back on, the charging update should say, plugged in, charging.

Word of warning, avoid sending it to HP if you can, as once serviced the warranty resets in 90 days…basically HP is trying to patch its bad hardware which is prone to overheating with a BIOS fix to make the fans run constantly at a low level… instead of turning on and running noisey when the CPU is real hot.

Ultimately the hardware is faulty, and most of these machines will probably have total failure in 2 years… if your running Vista and not MCE 2005 the failure rate will be higher as Vista is more graphics intensive.

if it is still under warranty you can chat with an online hp tech who will check it out over the internet and send you a replacement for free. the hp dv 6000 laptops have a recall on a few problems and there is a bios update to fix it before it happens but will not correct it after the fact the recall on specific problems extends the warranty to 24 months ( should get you to the warranty page

Basically, power down the laptop and then remove the AC adapter plug. Remove the battery, perhaps wait a minute. Then put the battery back in and then plug in the hp pavilion dv6000 ac adapter plug. You then should see the charger light come on showing the battery is charging. Perhaps wait a few minutes before powering on the laptop to confirm that the battery is indeed charging. The problem seems to be in the logic (not sure where, if it is the software driver, etc.) when the laptop is on, it doesn’t get a charge. But with the laptop off, plugging in a battery after it has been removed – it works with a simpler charger system that doesn’t use the computers’s main CPU.

Also second , it is clear with my 6000, that the battery can discharge all the way after some time when powered down even though it had say 50% or more! This is well beyond the normal battery idle loss over time and I suspect the laptop has turned on in some way to drain the battery. So I always remove the battery after I have powered down the laptop, and I have not had any battery problems since then!

Tips of Laptop DC Jack Repair

Modern laptops are all sold with built-in wireless ac power adapters. Some power notebooks used by corporate road warriors will have powerful cellular adapters that connect the laptop to the Internet via the cell phone infrastructure

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with dell pa 12 and hp pavilion dv6000 notebooks. If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it’s still under warranty, it would be fixed at no charge to you. Problem symptoms:

  • Laptop randomly shuts down without any warning.
  • Power LED and battery charge LED start flickering when you wiggle the power * cord or the AC adapter tip on the back or your laptop.
  • The battery will not get charged.
  • When you plug hp dv6000 ac adapter, the laptop appears to be dead and there is no LED * activity at all (DC-IN jack on the system board is broken).

To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. dell pa 12 and hp pavilion dv6000 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system board with a magnifying glass. In most cases you get the power problem because of a bad connection between the DC jack and the system board, you’ll see a crack between the DC jack connector and the system board.

tips of repair a laptop battery

The first laptop I ever owned was a hp dv6000 and the hp pavilion dv6000 battery was down to 20 minutes life after about a month. I yelled about it at hp until they sent me a new laptop battery, which was stone dead within a few weeks. Laptop batteries from some manufacturers have notoriously short lifespans (not mentioning any names here:-), and the Ni-MH (Nickel Metal Hydride Battery) which replaced NiCd (Nickel Cadmium) in most applications just aren’t that much better. So, I thought I’d crack open the stone dead battery back and see if it could be rebuilt. The first thing I learned is that laptop battery packs aren’t built to be rebuilt, they GLUE the things closed. Took some serious prying to get the thing battery pack open, but definitely in reusable condition.

HP/Compaq Pavilion DV6000 Battery 12-cells 8800MAH Description:
Cell Type: Li-ion, 12-cells
Voltage: 10.8V
Capacity: 8800MAH
UL certificated cells inside!

There isn’t a whole lot to a laptop battery, just a hard plastic shell, enough individual cells to make up the required voltage, and a thermocouple. The black wire scotch-taped between two battery cells is the thermocouple, and it’s positioned to measure the air temperature in the battery pack, not the actual battery surface temperature. Maybe that’s why the batteries fail so fast. The only other component in the battery pack is the little circuit board (below), which has nothing on it but the contacts for the notebook DC circuitry. Looking at it from the outside, you would have thought there was some fancy charging circuit inside, not so. When you buy a replacement laptop battery cheaply at , you’re just getting a new set of cells to run down.

The individual cells that make up the laptop battery(dv6000 battery) are simply strapped together with little contact strips which are soldered in place (below). To repair a laptop battery, you need to replace all the cells and resolder, but here’s the problem. that’s the first one that came up in Google. To cost effectively repair a laptop battery, you’d either need to find the replacement cells wholesale, or be doing it for a laptop whose battery is just ridiculously overpriced to start with. Live and learn.I searched around for a price on the cells at, you only spend $76.99 to replace the dv6000 battery.

how to repair Dell Latitude D800 ac adapter on a laptop?

Your laptop goes dead and you don’t understand why because it’s plugged in. The very first thing you should look for is status LEDs. The transformer brick or ac power adapter usually has a status led on it to show that it’s plugged into a good outlet and is functioning. If the ac power adapter for laptop LED is not lit and the cord is firmly seated in both the transformer and the wall outlet, then the AC adapter is probably bad.

Indestructible repair for the broken HP DV 9000 laptop hinge & case

I wouldnt recommend just anyone trying this repair if you dont have patience and a little bit of mechanical know-how… There are a few steps here that are critical that they are done correctly or the LCD screen wont fit back into the case chassis. I will try to go into futher detail with the step by step pictures that I have taken during my repair. *Any pieces that are removed must be put into a separate container so they will not be lost during the repair process!!

Well like everbody else who has purchased a HP DV9000 laptop, my left hinge has cracked and in doing so, also broke the embedded locknuts in the top LCD cover. I have had this HP DV 9000(hp Pavilion DV9000 AC Adapter) for under a year but refuse to send it back for service. I havent tried to contact HP after reading all the hell stories everybody else have had in doing so… So being creative and having all the tools, I decided to give it a shot to fix it myself

1、You must remove the 3 little rubber screw covers located on the top edge of the laptop screen at the right, center & left side using the mini flat head screwdriver. Then remove the 3 screws located under the rubber covers.

2、Then you must remove the outer screen bezel, which unsnaps. Be very careful not to force the plastic for it may crack! I would start from the left hinge corner which is probably open, working clockwise with the little flat head screwdriver prying it apart every inch or so. You may also have to re…

3、Now that the LCD is fully exposed you can see how destroyed the hinge and assembly points are damaged DUE TO POOR CONSTRUCTION BY THE MANUFACTURER’S DESIGN!!!

4、Then you must unscrew the 2 very small screws that are on the left hinge connecting to the LCD screen. Now take notice how much space is between the bottom of the LCD screen and the left hinge assembly. For this is one of the things that can make this repair render your efforts useless when you t…

5、Now you must free the tired hinge. Depending on how far trashed your top cover mounting points are. Try to unscrew the 4 little phillips head screws from the hinge (only 3 if you took out the one that was covered by the rubber screw cover already) If the screws turn and do not come loose the moun…

6、Push the screen all the way open holding it at the right and left hinges not to cause any further trauma. If your hinge is to far gone and you cant move it, you will have to force the hinge with pliers when you remove it during the next step.

7、Now try rotating the left hinge asssembly away from the LCD screen(hp Pavilion DV6000 AC Adapter) towards the closed position. You may need to use pliers on the hinge to rotate it because the torque required is significant and is partially the reason your laptop hinge is broken to begin with. Now that it is in the almost close…

8、Now you need to put a bend on the angle bracket. Use a bench vise if you have one or clamp a vise grip to the egde of the bracket, with another large pliers start the bend, With a hammer bang the bend flat. *This is a critical step! The bend must take shape with the hinge! Dont over bend or you …

9、As you can see my edge was completely separated on the hinge arm. I didnt do this but I recommend that you superglue the join on the arm so it will not move and in its original position so when you go to put it back together with the LCD screen it sits correctly in the chassis. Overlay the hing…

10、Mix up a small batch of epoxy. (you must mix the 2 parts thouroughly and work quickly so it dont set or you will not get the proper bonding strength) Smear a good amount of epoxy onto the hinge at the contact points and clamp without throwing off the shape of the hinge. Use about 3 to 4 mini cla…

11、Now that the epoxy has set remove the clamps on the arm. If you have a center punch mark 2-3 points where you will drill for your pop rivots in the center of the arm. (I used 1/8″ aluminum so I only put 2, I would or rather used smaller and put 3.) Push pop rivots from the outside of the hinge a…

12、I also added a pop rivot into the front face of the hinge just keep in mind you dont wont to block the holes for the screws. You will now have to drill through the back of the hinge out the bracket the small holes for the original screws to fit. Then bore the front face of the bracket with a 3/16…

13、Now grind the bracket so it takes shape with the arm also shearing down the pop rivots smooth on the LCD side of the arm. Then, although I didnt do this on mine because I wanted it to have the most strength, you may want to so the face bezel fits completely closed when you snap it back on later …

14、Keep your fingers crossed and put your newly repaired hinge in place to see if it fits correctly. Push the hinge to the fully open position very carefully so it lines up the top cover holes. If you used 2″ brackets and it lined up the same as mine you should only have to use a razor and cut out…

15、Now depending on how bad your mounting holes were damaged, will effect how you do this step. I had all 3 broken off, so I put the 3 screws in place and tightened the brass contact points snuggly to the hinge. Next cut the HP warranty-voiding insulating mylar so you can access the set points easil…

16、If epoxy is set hard you may now put back the LCD. First take out the 2 top screws holding the arms to the cover. Put the 2 left & right side screws into LCD screen. Make sure all the contact points and webcam, etc are lined up.

17、Indestructible repair for the broken HP DV 9000 laptop hinge & case
Take LCD bezel and flip over. Then cut the 2 clip contact points offwith a razor, smooth to the bezel. If you did grind down the face ofthe bracket against the hinge edge, when you snap the face bezelback it should close back like new or if you didnt you will have a veryunnoticable gap in side, b…

18、final step
Put the 3 top screws and the 2 bottom screws back into LCDbezel into the laptop casing, then put the 5 rubber sticky padsback on and you are done. Hope it worked out for you!!! This HP hinge repair can also be seen at Thanks for looking at my fix!

How often should I use my AC?

i just moved into a two bedroom two bathroom apartment in Southern California. It gets really hot in the late afternoons and I get tempted to use the AC. Normally, I turn the AC on for about five hours a day and then use ceiling fans when I go to sleep.

I really don’t want to get a high electrical bill in the mail, so I am concerned about how much running the AC everyday will cost. The AC unit is one of those energy star efficient types, if that makes a difference.

Please give me a dollar amount estimate of how much running the AC 5 hours a day every day will cost for a month. Thanks in advance.

two things

1. there are no answers to your question. it depends on the quality of insulation in the apt. size of a/c etc(Dell Inspiron 9300 ac adapter).

2. now, having told you you can’t get the answer. here’s your answer-sort of.

the electric company can tell you the average usage (cost) of your apt. the problem-you don’t know how much the last tenant used it or what temp they set the a/c on. so you can only assume they ran it full time and set at around 80, but that’s a guess. the electric company will allow you to pay the annual cost in equal monthly payments-that’s based on the last years cost.

as for comparing a/c to fans. you can’t put enough ceiling fans to equal the cost of the a/c. the a/c is 30 to 40 amps at 240v the ceiling fan is about 1 amp at 240v so it would take 30 to 40 fans to equal the a/c. what I would suggest is a combination of both. turn the a/c to 80 or 85 during the day with the ceiling fans running. then lower the a/c to what you are comfortable with when you get home-still running the fans. the fans will allow you to run the a/c at 5 to 10 degrees higher than without the fans and having it on during the day at the high number allows the a/c to work less to get the house to temp when you need it.

you should probably talk to someone in the heat and air biz. I was told once by a heat and air guy that it takes more energy to run your AC (Dell Inspiron 9200 ac adapter)on high for just a short amount of time per day during the hottest hours then to leave it on low all day. Turning it on during the hottest part of the day forces the AC to work harder which means it is pulling more energy which means more money.

Running it on low all day and turning it off at night results in less work for the AC and is supposed to save on energy which will save you some money. This was years ago when I was a poor college student and the guy was nice enough to fill me in. If you’re still not sure what to do then you might talk to someone who does know and that would be a air conditioning specialist because they know exactly how you can save money on your energy bill. delivers high quality laptop batteries, laptop AC adapters, Laptop keyboards, Lcd chargers, DVD drivers, Scooter chargers and more.
