The customer brought his Toshiba Satellite A85-S107 and complained that the laptop will not boot. First of all, I tried to start the laptop with a known good AC adapter, to make sure that the customers AC adapter is not a problem. The laptop didn’t start and there were no LED activity, the unit was “dead”. The good AC adapter wasn’t able to start the laptop. I started removing the laptop components one by one trying to eliminate the problem. I removed the battery, the memory module, the wireless card, the DVD drive and it didn’t fix the problem. I had just very few parts left: the system board, the CPU and the switch board. I remove the keyboard to check the power switch board and found that the switch board cable wasn’t properly connected to the system board, it was half way out. I reseated the cable on the system board and the laptop started properly.
BTW, the system board has 2 memory slots and by default the memory stick is located in the slot hidden under the keyboard. BUT, it is not enough to remove the keyboard if you want to replace the original memory module. After you remove the keyboard, you still will not be able to remove the memory because it is hidden under the top cover. To replace the original memory stick in Toshiba Satellite A85 you have to remove the entire top cover!!! It sucks!
Here’s a disassembly guide that shows how to replace a memory module on Toshiba Satellite A85.
