So I was loading google earth on my galaxy tab last night, and it froze. It crashed hard. So I held down the power button for 10 seconds or so, and it shut off. However, it will not restart. I hold the power button down and nothing happens. I had above 50% charge when this happened, but I tried charging it overnight. It showed no sign of accepting the charge, but I left it plugged in all night anyway. This morning- still nothing. The Tab appears, for all intents an purposes, to be dead. Anyone else heard of this problem?
