Pressing power button does not turn on

Pressing the power button, Unit does not turn on. Button lights up for a split second, drive does not turnover. Disconnecting power cord and reconnecting does not help. Is the problem the power button or the drive?

It's probably the power supply. Do you get any diagnostic lights on the logic board?

UPDATE 2/26/16

The diagnostic LEDs should lit up when you press the power on button if the power supply is good.

There is also a CUDA logic board reset button on the logic board. Press the CUDA button, ONCE! It is located to the rear of the battery housing. It looks like a small pencil eraser in a metal square..

Have you replaced the 3.6V/850mAh 1/2 "AA" Lithium PRAM battery?

I will check. Will lights be present on the logic board with plug connected and the unit powered off though?
