Q: I lost my I pad and find my phone was turn off..Does anyone know any other way to track  it?

If the iPad was running iOS 7, the thief/finder will not ever be able to use it.

Apple (and no one else) can not assist (with serial number or iCloud) in finding a lost or stolen iPad.

Report to police along with serial number. Change all your passwords.

If you don't know your lost/stolen iPad's serial number, use the instructions below. The S/N is also on the iPad's box.

Check the serial number (located on back/bottom) in this lost/stolen iPad database. However, most owners are not aware of this database and don’t enter the serial number.

Also do a search, using the serial number, on your local Craig’s List. Some users list the serial number of a stolen iPad to thwart the sale of a stolen device.
