When the power cable is plugged into laptop, the light or power is off.
Cable is good, and power is present at connector on motherboard. Connected a power supply to motherboard and slowly increased voltage. At around 1 volt the supply tripped off. Suspect a bad power distribution regulator. I need help finding and replacing this part.

If your computer refuses to boot or tends to turn off without warning, see the Faulty Power Supply to Motherboard problem page for possible causes and solutions.
