i plugged in my iPad to the computer earlier today, synced it then unplugged (i didnt eject though because my i had already closed my itunes). after that it just wouldnt work. i tried to plug it to the computer again but nothing happened. i tried pressing the home and sleep buttond, seperatly and together, but nothing happened, the screen is still pitch black. i also tried to plug it to the wall socket charger, i was thinking maybe the computer didn't recognise it, but still nothing... anyone has any idea how i can solve this? i would greatly apreciate the hel.
