Hp victus not charging

[amr soliman]

Hello every one
I have hp victus Dag3pamb8d0 rev d
The laptop came with shorted n-ch 165 Amp mosfet I replaced it with n-ch 100 Amp mosfet
Now it works but not charging also 5v is OK but 3.3v is 1.35v
Don't know where is the problem
Can any one help to trace it

3.3v is 1.35v

Remove all power. Meter in resistance mode. Measure the resistance to ground of this 3v3 rail. What is the exact resistance in ohms?

I remove the 3.3v coil rail is 54ohm from coil ic side from the other side it's 3.356 miga

So there is a partially shorted part on this rail. It could be the pch (cpu). 54R ohms is too low.

The laptop boots otherwise? Then cpu is ok.
