My Ipad 16GB wifi had been working flawlessly for the past 3 weeks. Was reading a book till about midnight on the Amazon app, turned off the screen and sit the ipad on the nightstand.....still had over 50% battery.... ...went to turn it on this morning and nothing....will not turn on. Plugging in to charger for an hour or the computer doesn't help. Looks like I'll have to get a replacement. Aaarrrggg.
