Set the 'power option properties' to 'never' on every options so the power will never be turned off. Why do you want to keep it 24/7? Are you using that for your phone calls?
YUH..that's what i did...more than 3 months now i haven't turn it off yet..if you go out just turn the monitor off. my CPU have a cooling system or AC something.lol...it alway feel cold on the side.
