Hi guys. I hope this hasn't already been asked before - I have 'MRoogled' it! When I turn off my iPad, I can't turn it back on again unless I plug it into the mains charger or iTunes. It is charged. Even when I hold home and sleep/wake for 15 secs it won't turn on. The sleep/wake button does work, as it functions when the iPad is switched on. Anyone else heard of anything like this? Many thanks for all replies in advance.
