Hello,
I have this board that had slight corrosion marks but no major liquid spill or anything.
replacing the 3 resistors that were damaged - R5641, R5193, R8167 didn't fix the issue
It goes to S0, kinda.
PP3v3_S0 - 3.3v
PM_SLP_S5_l - 3.3v
PP5v_S5 - 5v
PP3v3_Sus - 3.3v
ppvrtc_g3h - 3.3v
PM_SLP_s4_l - 0.9V
PP5V_S4_RS3 - 1.1V (starts low and builds to 1.1)
PP1V05_S0 - 0.16V
ALL_SYS_PWRGD - 0.01V
PM_SLP_S3_BUF_L - 3.29V
PM_S0_PGOOD - 0V
No pulsing on any missing rails
No pulsing on any rails with low voltage. They start at it.
The PCH signals are present
u3900 gets warm enough to be detected by hand but not hot.
Nothing else gets hot.
All voltages for u3900 are present
No shorts found on any of the rails i checked. I checked most of the S0 and S5 that are missing.
