The "secret" charge. On many computers there is enough power provided over USB to charge the iPad (slowly) but not while the display is on. So it will be charging but then as soon as you try to see if it's charging, it stops. Very tricky iPad. My advice is to leave it plugged in to the computer for an hour or so with the screen off and check the percentage meter. Jordan --- Manage your account options at //www.freelists.org/list/muglo
