Yeah Phil, I thought about a solenoid or something but there’s no room back there for even the smallest one I could find. I know the tablet can tell if it’s being fed power or not but I don’t think it can tell whether the adapter is plugged in or not. Maybe it can and I just don’t know?? It can tell when the headphone is plugged-in..hummm..?? Do you have any ideas if it was possible?
In any case, this is my “mechanical” solution for now – LOL!
