I had a similar problem with one someone had brought me to see if I could
get it working. It ended up working, but (and I *hate* this) the reason why
was and is unclear. 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.
