My Toshiba A75-S206 has the intermittent power issue. We followed the step-by-steps, took the beasty apart, and found that not only was the DC jack loose, but it had bent prongs inside. I need to know how to safely remove the jack and replace it with another one (which I already have in my possession, thank you eBay). I am new at this, and don’t want to destroy my machine, but as I am a student and a single mother, I cannot afford even the $200 cost for repair at the laptop shop anymore than I can afford $600 for a motherboard. Thanks for the assist!
If you have never soldered before, then it’s not a good idea to get your first experience on a still working system board. I would recommend finding a repair shop or a local computer geek who can help you replace the jack. It’s shouldn’t be very expensive because you’ve already removed the system board. You can search on Craigslist. Be careful with the system board, it’s sensitive to static electricity and can be easily damaged. You have to keep and carry the system board in a special ESD bag. Ask for ESD bag the person who is going to repair the board.
After the power jack is replaced test it before you assemble the laptop. Install the system board in the laptop base, connect the CPU and the cooling fans if you removed it before (it’s not necessary to remove the CPU and fans if you want to replace the jack). Connect an external monitor and turn on the laptop (the power button is located on the system board). If everything is OK, the laptop should start and you’ll get Toshiba logo on the monitor.
