Thanks for your help everyone. I have let it run right down and then charged up again (its first charge as only had it a week). I don't have lock on it's as though it's "faltering" at start up, switches on, for about a second then screen goes black, I then have to just touch the start up button again and it comes on for me to slide to open and all is well after that. Can't figure it out really as I have the same settings on mine as my friend and they don't have this problem at all.
Ed I didn't realise that with not switching off completely as I read on Apple to conserve battery power to shut down amongst other things - well I think I did lol..now you've got me wondering oh dear lol.
