This is what resulted from this, PTN3222 losing its state on deep suspend when the vreg shuts off. And it solved the problem, propagated it over to the Ideapad 5 device trees. I also observed that on the Ideapad 5 2in1 before. Never seen on the Slim5x, but I got that one after the change was in. So, yes, IMO. Alright, let's at least leave a comment for the future reader Konrad
