How to repair damaged Toshiba PA3237U-1ACA AC Adapter power jack

In order to access and repair the Toshiba PA3237U-1ACA 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 Toshiba Satellite L355D, 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 Toshiba PA3237U-1ACA AC Adapter power jack harness and laptop base. This repair will easily cost over $200 but I have a better idea how to fix it for $3 without replacing the base assembly.
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 Toshiba PA3237U-1ACA 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 Satellite L305D) 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 Toshiba PA3237U-1ACA 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.
Now mount the new power jack on the base. Solder wires to the new jack. Again, the red wire is soldered to the lead in the center and the black on to the lead on the side. The new (modified) power harness has been installed into the laptop base. Now you can tighten the nut on the Toshiba PA3237U-1ACA AC Adapter power jack and secure it on the base. Remove plastic reinforcement walls so they do not touch the Toshiba ac adapter power jack when the cover is installed. If you leave these walls, there will be a gap between the cover and base.
By the way, if your laptop is still under warranty, Toshiba might fix this problem at no charge. Call them first or take the laptop to the authorized repair center. If this modification works for you, please mention the laptop model in the comments. You are welcome to post any suggestions and improvements.
