[anneasquith]

should i turn off or log off ? compared to a tv, is computer use more expensive to use . thanks

I always put mine into `Hibernate` instead of logging off as it`s quicker to log back on and apparently doesn`t use any power, and I disconnect the cable modem also.

Power usage, of course, varies between different computers, one of the main things that uses electrictiy is the monitor with old CRT type monitors using a lot more than modern LCD ones.

taking a fairly average system (with a LCD display) the typical power usage is about 200watts while on, about 20watts with everything on standby (sleep) and about 10watts with everything turned off.

to give a "real world" comparrason to keep a computer in each of the 3 states above for 10 hours (based on a electricity unit cost of 12p) would be......

on - 200W = 24p per 10hours
sleep - 20W = 2.4p per 10 hours
off - 10W = 1.2p per 10 hours.

of course unpluging or switching off at the wall would reduce the above to 0p
