iPad USB port broken?
When I plugged my iPad into my laptop USB ports the battery icon did not change and the laptop did not acknowledge the iPad as connected. The laptop's ports are fine, and I tried a few different USB cords, so I believe the problem is the iPad USB port. I tried plugging it in to the wall and it worked after I restarted, but the next few attempts did nothing. I left it plugged in overnight and when I turned it on in the morning it was still at the same percentage, but when I unlocked it the number doubled suddenly. It appears to be draining normally, but there is no response to being plugged in.
iPad, iOS 5.0.1
