Re: I have iCloud and my iPad has "icloud backup= this iPadhasn't been backedu in 2 weeks. Backup happens when this iPadis plugged in. locked,and connected to wifi . the window bubble will not go away and I am unable to unlock anything.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
