battery is fully discharged, got no other compatible one i put back old TPS chip, now takes 20V but low side mosfet on main rail is very hot

Well, better replace both mosfets Was the new one same?

they are still hot, the cpu does the same "exploding" pattern and the current draw is huge around 14A @ 20V yes can cpu somehow affect switching of the TPS chip on mosfet gates?? actually, maybe what happened is that old TPS died, sent high voltage through data lines to cpu and killed it and now it has this weird pattern i was sure someone else had this pattern on the processor before thats why i asked

Not in that state I think. Check qc2a and qc2b, maybe also. If those are ok, it's highly unlikely that cpu was damaged by the controller. What was the original problem?

ok quick question, how much is VCCIN supposed to be voltage? its SRK04 i think it should be around 0.8-1V ish right? on here when the board sometimes starts by itself is 1.8V i dont think thats good and cpu is 99.9% cooked i think
