So if I understand you correctly, the S4/3/0 Power Rails shouldn't be present if no button is pressed ?
And if they are, U8000 could be faulty as its giving out these Lines ?
which voltage did inform you about the "always high state" of this rail ?
Or better said - how did you know?
And this voltage should only be high if "on Button" is pressed?
sorry i get green light and orange light !
Edit:
I now ordered a Stencil to Reball the SMC.
Gonna inform you if something changed !
Do you think the Problem is solved after reballing or should i change the SMC?
Thanks for the help !
