    Acer Spin 5 LC56-14A AMD White Light on Esc and Caps lock Key and Blinking power btn

    System doesnt post, I have found that 3v 5v and 19v rails present and accounted for.

    theres 19.5v with a 2amp current drawover usb c charging

    I have tried a new bios and cleaned me region but no change in behaviour.

    I have noticed that the Mosfet PU4403 gets quite hot 60 degrees, but cannot find a short on it or surround components also pu4401 which is the BQ charging chip is also quite hot 60 degrees.

    Have removed BQ and checked pads but no shorts.

    Also on PU4405 PIN 2-4 is suppose to be 19v as per schematic 19V_dcbatout but im getting between 11-and 13v

    I have prodvided a schematic and boardview if anyone can point me in the right direction i would be very greatful


    Kind Regards
