iPad down, can anyone help?
Problem: not being able to turn on iPad, no response at all to the on/off button
Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. Happened to me once, about 7 or 8months ago, and a reset got it working again.
