I cant remove icloud backup message on my ipad? my ipad now wont turn off or unlock

What this message say?

I have the same problem, it says

"this ipad hasnt been backed up in 2 weeks. backups happen when this ipad is plugged in, locked and connected to Wi-Fi"

however i have done that and plugged it into my computer and it has synced as normal, but this messages still appears and pressing ok does nothing. Any help is appreciated.

Settings>iCloud>Storage and Backup>Backup now.

I am experiencing the same thing...only my message says it has been 3 weeks. Haven't used ipad very much due to illness since I received it at Christmas so there isn't much to back-up if anything.

Have ipad plugged in. Can't unlock computer to access Settings. When press okay in icloud message box, the screen goes black. Would like to disable iCloud altogether but can't even get into ipad to change anything! Tx Helen

Try pressing and holding the home and on/off button together.
