my Ipad is not waking up any more when I open the cover
My 4 y.o. Ipad is under the weather. Not only it doesn't wake up any more when i open the cover, but, the "home" button has become insensitive and I need sometimes to press it for a relatively long time for anything to happen. To cap it all up, a message has appeared that says that the Ipad hasn't been able to back up for 3 weeks, and this despite that it has been locked and recharging almost every day. Any ideas?
