Computer problems... Hi! I have a dell computer and it keeps on going onto power save mode. I turn it on and the on button instantly goes orange so I press a button next to it ( i don't know what the button is) and hooray; the on button is now green, but only for a few seconds and whilst that, it says power saving mode press the keyboard to get out of it. I do and still doesn't work! Please reply to me if you have a solution! Thanks, Beth.
