same problem here---I have a stack of four iPad 4th generation that all have either fake charging or no charging. They will sometimes detect usb with original cord on a mac, other times not. If I lift off battery connector to reset it will detect charger, then fake charging.

One iPad will auto power on after red slider shut off.

This SOUNDS like the iPhone 5 U2 chip failure---has anyone seen this in the iPad 4? Where is the usb charging logic ic---is it the same chip as iPhone 5?
