Hp touchsmart 520 won't power up

My Hp touchsmart 520 won't power on.


The power supply puck shows 19 volts when disconnected and the green light is on.


As soon as I connect the power supply to the computer the light goes out which tells me something on the computer power bus is overloading the power supply.


Any idea as to how to diagnose and correct?
