I've always wondered about this also, I usually put mine in standby during the day if I'm not using it and hibernate overnight. My brother (who services and builds computers) leaves his on 24/7 and told me to do the same. I was always under the impression that the electric bill would be through the roof leaving it on 24/7, now I know it's probably worse always shutting it down or hibernating. I just always feel that my fan is going to die during the night and overheat my computer..
I guess mine's a full timer now!
