The charge indicator LED is solid white when connected to the power adapter, so I know the battery is fully charged.
A few days ago, I put my laptop into hibernation. It seemed to shut down nicely. Later that day, I pressed the power button to turn it on, but nothing happened.[br]
[br]
The next day, I opened it up and found the power button had broken from the power button board. So, I purchased a new power button board, part 774599-001 and installed it. Still, when I press the power button, nothing happens. No lights, no sounds, no clicks -- nothing.[br]
[br]
So, I may have one of these three conditions:[br]
1. Something on the system board has failed. When it didn't power up, I may have pressed the power button with too much force and that is what broke the button. Now I have a new power button board, but the m/b is still faulty.[br]
2. The power button board that I installed is faulty. I can get a replacement for the replacement.[br]
3. I somehow caused a new issue while I was working on it.[br]
[br]
I have tried powering up with and without the power adapter, performing a power drain, starting without the battery connected, and holding the Windows-B keys. Nothing has helped.[br]
[br]
What should I try next?[br]
Does anybody know which of the 6 pins in the power board cable can be shorted together to start the computer? If that works, I will know that the power button board is bad, and the system board is good.[br]
Where can I find a schematic for my system board?
