I have a Toshiba A105-S2101 PSAA5U-01300Q that will not power on. The power LED and the battery charging LED are working fine.I switched the power button board with a nother laptop that works fine with the same results. After stripping everything from system and tried to power it on and it worked. The LED showing that the unit was running came on. I started putting back the parts one by one and trying the power after each one. I got it all back together and it was working fine. I formatted the HDD and clean installed Windows XP and after several usages the system now will not power on. Please help with any ideas.
