820-2936 - no water damage. both the usb ports don't work, but keyboard and trackpad works which is funny. I put in a usb stick. i'm getting 5v .275v and 3.1v on the pins. so its getting voltage, but not popping up in disk utility

so i bumped up the voltage from 2 to 4v on psu and found short on c7431. solved.
