My only indication of available power is the LED at the power button flashes red. This power indicator sometimes illuminates green momentarily, but quickly changes to flashing red. This is a stock Compaq Presario model 6016us, w/200w psu, which I believe to be faulty. It has a 20 pin power connector, AMD cpu@1.6Ghz. and 512ram. I have taken voltage readings at the motherboard connector as follows:

orange: 0 volts static, when pwr button pushed, 5.4 falling to 0 in few seconds
red: 0.1 to 0.3 volts static, falling to 0 volts after pwr. button pushed.
white: 8.8 volts static falling to 0 rapidly when pwr pushed.
blue: 0 and 0
grey: 0 and 0
green: 14.9 volts and no change when power button is pushed.

Westom, are you out there?
