Hello,
I have another no power logic board that i've been fighting with. Came in with heavy liquid damage. Replaced all the corroded and suspected corroded components but still not getting power on s4. Here are the readings:
PPBUS_G3H - 8.58v
PP3V42- 3.4V
PP5v_S5 - 5V
PP3v3_S5 - 3.3V
PPVRTC_G3H- 3.324v
PP5V_S4RS3 - 0v
PP3V3_S4 - 0V
PP3V3_SUS - 3.3v
SMC_ADAPTER_EN - 3.4v
PM_BATLOW_L - 3.3v
PM_RSMRST_L - 3.3v
cycled SMC_ONOFF_L and went from 3.4v to 0.35v on PM_PWRBTN_L.
PM_SLP_S4_L also pulses during the SMC_ONOFF_L cycle.
Any suggestions would be much appreciated. Thanks
