iPad2 needs to be restored but won't charge
My iPad2's battery ran out during use in a normal way. When I went to plug it into the charger, it began flashing between the Apple logo and the dead battery symbol. After researching and trying hard reset, I determined it needed a restore so I put it in DFU mode. I left it alone plugged in for about an hour. It apparently charged just enough so I could get the restore started because it flashed the dead battery symbol just after the restore was beginning. I then plugged it into the charger again and now it shows the symbol asking to be plugged into iTunes. I left it for 8 hours and tried the restore again but now it apparently won't charge enough to do the restore. I can't get the symbol saying it needs to be plugged into iTunes to go away so maybe that's draining the battery as it's charging. Any ideas??
