I recommend to reball SMC, very probably soler balls affected by corrosion.

Do you get 3V3_SUS?
Post PM_BATLOW_L, SMC_ADAPTER_EN, PM_DSW_PWRGD, PCH_DSWVRMEN, PM_RSMRST_L and PM_PWRBTN_L.

I'm not sure what you mean.
But I think if I hit the reply icon it will quote the whole thing. I apologize if I have been.

"Pm_Dsw_pwrgd 0"
Do you stil have 3V3/5V_S5 present?
If yes, check R5192 and R8141.
If good, there is an SMC issue; did you reball it?
