how to replace Dell Inspiron 600M ac adapter for laptop?

In order to access and repair the Dell Inspiron 600M ac adapter power jack, it’s necessary to disassemble the laptop and remove the top cover assembly (palm rest). Here’s an example of removing the top cover assembly from a Dell Inspiron 500M , you’ll have to follow these steps.

In my case both, the Toshiba ac adapter power jack and mounting brackets on the base assembly got broken. Even if you replace the broken jack with a new one, it will not stay attached to the base. If you send a laptop with a damage like that to a repair shop, they will recommend replacing the Dell Inspiron 600M ac adapter power jack harness and laptop base. This repair will easily cost over $200 but if you don’t repair it ,you can spend $17.99 to buy new ac adapter at udtek.com(http://www.udtek.com)

Dell Inspiron 600M AC Adapter 65W 19.5V 3.34A Description:


Input: AC100-240V (worldwide use)
Output: DC19.5V 3.34A
Power: 65W
Connecter size:
Internal Diameter: 5.0mm
External Diameter: 7.4mm
With central pin inside
Item Includes: AC Adapter and Power Cord.

Using a pocket knife remove plastic supports from the internal side of the base assembly, so the side where the new jack will be mounted is flat. Again, using the pocket knife remove the plastic wall surrounding the mounting hole. Make the hole larger, so then new jack fits in.

The new Dell Inspiron 600M ac adapter jack is too long and if you install it as is the laptop cover will not sit properly on the base. It happens because one of the speakers (in Dell Inspiron 500M ac adapter ) is located very close to the power jack. It will work if you make the jack shorter. You can cut off part of the long lead or simply bent it as I did. After it’s done coat both leads with generous amount of solder.

Now remove the damaged Dell Inspiron 600M ac adapter power jack from the laptop and cut off wires somewhere close to the jack base. Remove isolation, twist wires and coat them with solder. The red “+” wire will connect to the lead in the center of the new jack. The black “-” wire will connect to the lead on the side – the one you made shorter. In some laptops Toshiba uses green wires instead or red wires. They also should be soldered to the “+” lead in the center of your new jack.

WARNING! Check the polarity before you apply power to the laptop.
