hello im working on this machine with full short on pp3v3_g3h
found the culprit on c6998. after i replaced c6998 i got pp3v3_g3h is present, now the device can able to switch on 20v.
but still not able to turn on. (can feel now taptic is clicking.)
i did some voltage testing everything is normal excepts on pp1v8_sus is missing did also diode testing is not shorted.
also tried replace u7800 from donor board (same board model number)
btw:measured also pp1v8_sus before i tooked u7800 from this donor board is present.
kinda no idea whats the next step.
TIA
