Water damage board around U5700, Q5800 5820 5840 and U8100.
Replaced U5700 then have 3.8v on PP3v8AON.
PP3V8_AON_MPMU_ISNS_VIN is 3.8V
P5vs2 and others S2 rails: 0V.
U8100 is fine as I tried to install this IC to other M2 board then it is working. U8100 seems to not turn on. I have checked all the rails arround and confirm no short.
what should I check next? and what is the condition for the U8100 to turn on. Also, what power sequence for this M2 macbook? thanks
