UPDATE:

Do you get 3V3_S5/SUS?

Sorry was check again:
3V3_S5 3.3V
3V3_SUS 0V

Trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L, at same time

PM_PWRBTN_L 3.3v stay stable with trigger SMC_ONOFF_L

 

[2informaticos]

Of course, if missing 3V3_SUS.

Check PM_BATLOW_L, PM_DSW_PWRGD, PCH_DSWVRMEN and all PCH's RTC signals.
Bre sure to use correct 85W charger.
