    Acer Aspire 5920G Will Not Turn On

    Hi all,

    Ive been asked to look at this aspire 5920G because it had some software issues. When i have come to work on it, it will not turn on whatsoever.

    The charge light comes on and the power light on the ac adapter is a steady green.

    I have removed the battery and ac adapter and left it to discharge for a period and still no joy.

    I have since tried a different ac adapter, i have checked for shorts on pc118 and pc112 just in case. All items have been removed and reseated.

    I have tested the switch and i get 3.3v and the switch behaves as it should.

    Hopefully someone is able to assist with this. Any help provided is greatly appreciated!

    Check for the basic pwm 5 and 3 volts.
    The schematics for that motherboard is here:

      Thanks for your help, one question though, is this referenced as +5VPCU and +3VPCU on the schematic??

        Reball the GPU. There's nothing else wrong with it, it's the classic nVidia GPU failure.

            The G in the suffix usually indicates discrete graphics.
