Did you try the following trick already?

Remove the battery and the power cable from the machine. Then press the 
power button every second for 20 or 30 times in a row. After that, press 
and hold the power button for 30 seconds or so. Then connect the power 
cable and try to power on the machine. Does it power on now?

For reference about what this does, see the first few entries found via

I had that happen a few time on a T61 due to a dying battery.
