Right, So this machine powers on only when plugged in. Charges battery and can shut down normally via the menu. Power button will not function at all! It will power off & on via the power pads on the logic board. However if left plugged in, it automatically comes on. This leads me to ask: Is it possible that the machine little daughter board could be short out and cause it to come on? BUT… Power button still dead I’m confused!
