I have two Ipad 3 (Actually one of them is my brother's). One of them works perfectly fine, in the computer ( I can open it through "My Computer" ) I also can connect/open it through iTunes. And the other one, whenever I plug it in the USB, it doesn't respond AT ALL. Not in iTunes, nor the computer itself. And I dont get the small note near the battery (Not Charging) There's no reaction at all. Is there any solution to this problem?? Is there any setting that enables the connection?? It's really worrying me, because i have tried to connect it a lot of times and it just won't connect.
