My wife got an iPad 4 for Christmas so I'm not too familiar with it yet, but up until today it was charging just fine. She would use the charge cable and AC adapter that came with it. Today, it just stopped charging. The battery indicator is there with the percentage but no lightning bolt. It's not the outlet, as there's other things plugged into it and they're charging fine. I removed the AC adapter and plugged the cord into my laptop via the USB and still no charging. Can anyone help me out with this? Faulty iPad? Faulty charging cord? Something easy that I'm apparently too stupid to figure out? Thanks everyone.
