820-00165 No power

[iClub]

Good morning, this mac has suffered oxidation in the region of C1212. It came from another service where they reflowed the SMC, replaced it, but it won't turn on.

Voltage:

PPbus; 8,59V
PP3v42: 3,42V
ALL_SYS 0,115V
PP3V3_S0 0,056V
PLT_RESET_L 0,032V
SYS_PWROK_R 0V
PM_S0_PGOOD 0v

Does not support SMC bypass mode

You've got for S0 voltages?
Why, did you already get S5 and S3 voltages?

 

[iClub]

PM_SLP_S4_L 0v
P3V3_S5_LL 0,543v
PP5V S5 0,930v
P5VS4RS3_EN 0v
S5_PWRGD 0V
PP3V3_SUS 0V

So not even S5 voltages present on the board.
You can't waste the time looking for S0 voltages in such case.

Post U7501 basic voltages.
You should know which ones to check, after so much time in the forum...
