Hello!
This board was clean or cleaned before I received it. Can't see any corrosion.
It does not charge the battery and it won't turn on from just power adapter.
If I install battery it goes to S0 state, but no CPU VCORE.
Fan is not running. GPU gets hot.
Missing ALL_SYS_PWRGD so no CPUIMVP_VR_ON.
I checked Q7950 and I have everything for ALL_SYS_PWRGD, but it stays at 0V.
I checked:
R7968
R7966
R7965
R7964
R7963
and are all 0V. However I'm sure I have PP1V5_S0 , PP5V_S3 etc.
However P1V5S0_PGOOD, P5VS3_PGOOD etc. signals are 0V.
I believe ISL fucked, but it looks clean. I checked sense resistors and traces and all looks ok.
I have green light, but with power adapter I don't have PPBUS_G3H. It's like 1.8V. With battery is all ok.
No short on PPBUS_G3H.
Should I first fix the PPBUS_G3H issue?
Thanks.
