This board had liquid damage to the entire area DCIN/3v42 of this board: from C7098,L7095 area through D7012, ALL of those components have been replaced. This board boots from PS input but not from original 85W charger.
On original charger:
PPDCIN_G3H is around 1.5V most of the time
Diode mode there is 0.5
I've replace D7012 twice, ISL twice, Q7180 3x (last time I did Q7180 at same time as ISL just in case), Replaced Q7010 twice
Resistors i've checked that measure good: R7005/6, R7010/1/2, R7180/1/5/6, R7105, R7010/1
REsistance between pins 17/18 of ISL is 2.1 ohms, 27/28 pins 20 ohms.
Once briefly after replacing ISL the board started but I believe this was shortly after having on power supply so not sure if that was related.
Any thoughts? I feel like I've replaced everything I could think of for typical leakage cause at least once.
