Acer Predator PH317-51-58Y2 dead

[luckydip]

working on this machine - dead but has 5v and signals on the EC. There is no +3VALWP - no 3V_EN - the bios/EC area are fluxed. Looking at the keyboard connector, the pitch looks off and the flat cable fits very loose. What do you guys think?

It seems the kbd connector lock is missing. U can try by cutting some extra tape(remove from bad kbd)

Check by shorting the power on key on kbd connector to gnd. Normally only 1 pin on kbd connector will be gnd and the next pin is the power on key

I tried that but got nothing. So I removed RB14, RB15 and DB1 (then bridged). I've now got +3VALWP but doesn't switch on. I then looked at PU301, all voltages seem ok apart from:

pin 10 /PROCHOT 0v

pin 26 HIDRV 200mv

pin 27 PHASE 200mv

Is it time to change PU301?
