I have an situation where I am mounting a tablet behind glass and I do not wish the power button to be active. The tablet has permanent power applied so the battery running down is not really a concern, but I am wondering if it is possible to detect voltage is OK and auto-turn on. i.e. auto-on if power DOES get disconnected and re-connected for some reason. And, also, to disable the on/off button so it could not accidentally turn the tablet off..........I don't think the PhoneWakeState is enough here?? thanks.
