Hello my friends
I have a laptop here that most of times not turn on
19V_DCBATOUT=3.2V
But sometimes,maybe one of 10 times that of it plugged,it turn on normally! And use about 0.4A
Battery is 0v and im not sure about battery and also not charge the battery
It use 0.003A when pluged

Pu4301,pu4415,pu4403,pu4404,pu4405,pu4406,pu4412 are good
Dcin=19v
PWR_CHG_VDDP=5.2V
Acin=3.8v
Acok=0v
19V_DCBATOUT=3.2v

Any hint where should i start checking?

Thank you all

Check again, or better yet, remove and check outside the Pu4301, pu4415 board. Not only Drain - Source, but also Gate - Drain and Gate - Source.
19V_DCBATOUT=3.2v ??? Is this with the battery on the board?
