What I did was to diassemble it and check out the backup battery and the power to the board: both were okay. The thing that finally got it working was when I removed the keyboard connector (probably under power) and put it back. I don't remember the thought processes (no comments please!) that caused be to try it. It happened again when the backup battery went dead and again, I was able to bring it back to life. I might add that I did have the power supply connected and plugged in when I did this. IIRC, the case has some tabs that hold it together, and after removing the obvious screws, the thing can be gotten apart with some gentle prying. Good luck.
