Ipad 2 won't go into sleep mode
Hi I know that this may be a stupid question but for some reason my ipad 2 won't go into sleep mode.
I hope I'm using the right terminology here. By sleep mode I mean I can have my ipad cover open for several minutes and the screen won't go into a sleep mode or go blank even though it is not being used all.
I know before it used to go to sleep within a very short time - now it dosn't sleep at all.
Is there a setting for this somewhere - I for the life of me cannot find it
