Yes, not sure if it will be the same for you. But i found out when i turned mine off completly and then plugged the cable into it, it would be forced on by the cable being plugged in. Then i could let it sit, without removing the cable, and let it charge. (Even though it said "Not charging" in the top right. This same method worked for the computer. Shut down the ipad, then plug the cable connected to the computer into the dock connector of the ipad and it should "Force" it on. After being forced on it would connect to the computer and then i could unjailbreak it.. Still havent gotten a chance to go to the apple store "Nearest one is over an hour away" But whenever I need to charge i just have to do that.
Hope this helps.
