Check the Voltage on those pins U48/49

pin 2 are raising to 0.6 volt and go to 0volt.
once both raising to 1.3 volt.
note:
both ic not on the board!! place is empty

That’s good news if the signal is coming from PCH but one of the sector after SIO is prevention it +3V S5 line might be the case but !! PQ37 pin 1 & BATLOW ?
If another Badcaps Veteran can help ?

tnx techtiger
PQ37 have a 3.3 volt
but BATLOW in shcematic PCH_BATLOW#!?
and in board i can't find it because no ID number of component in near cap or resistor just ic's have a ID number in board .
