My iPad was charging. I unplugged it and turned it on. The iCloud box was on stating that it could not back up iCloud. I am unable to get the unlock button to work or get rid of the iCloud box. Any suggestions?
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.
