I have this board that was liquid damaged around by the SMC U6100, and U7501 mostly. I have UC'd the board and replaced U7501 as well as some resistors that were damaged by the SMC.
I am now getting 1.57v on PP5V_S5. I checked for PM_SLP_S4_L and it is showing 0v and not even a pulse when the machine turns on.
Here are some other measurements I got.
SMC_ADAPTER_EN - 0v
SMC_S5_PWRGD_VIN - 3.4v
PM_PWRBTN_L - 0v
PPVRTC_G3H - 3.4v
SMC_RESET_L - 3.4v
PM_SYSRST_L - 0.06v
PM_PCH_SYS_PWROK - 0v
PM_PCH_PWROK - 0v
PM_RSMRST_L - 0.02v
PM_SLP_S5_L - 0v
