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.

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.

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.
