my in-laws dropped their ipad2. it was in a case and didn't fall too far/hard, but enough screw it up somehow. if it is asleep and you wake it up w/the front button, all that happens is the screen goes from black to a barely lit dark, dark solid grey. can't reboot because the screen won't display the off switch. my last resort is letting the battery drain completely, recharging it and getting a reboot out of it that way. any suggestions, or is it toast?
