Hey all I had my tab plugged in and recharging in the other room. I know it was on, because I heard a couple of notifications go off. But when I returned to the fully charged tablet, I first unplugged the cord from the unit, then touched the power button. Nothing. I had to long hold the button and do a complete startup. Anyone have that issue with randomly shutting down during sleep while charging? This is the second time that's happened.
