The machine is a dual 867 G4 with all factory components.

I unplugged the machine for a few hours this morning. I believe it was in sleep mode when I unplugged it....

I plugged it back in and now it won't power up. The power light comes on while my finger is on the button then fades out, nothing else appears to move. Anyone have any idea what this could be?

here's the solution and link in case anyone else comes upon this:

1. Disconnect the power cord.

2. Press the PMU reset switch (S1) once on the logic board. Do not
press the PMU reset switch a second time because it could stop the PMU
chip from responding. (See

3. Wait ten seconds before connecting the power cord and turning the
computer on. If the computer does not turn on, there is something else
wrong with the computer.
