Hello
I do not do many motherboards and I was asked if I can something to repair it.
So, I said yes (kind of forced!).
I started checking PW from plug ... then found there was no 3v3 on PW switch.
Then I checked various mos-fets as I did not have schematic - which then found here - thanks.
Not finding anything work - LED on Vin is not pulled down, I then finishes taking motherboard off the laptop and checked other side and found PQ48 practically shorted and getting slightly warmer.
I also checked it visually...
