Q. Should I put my computer to sleep or shut it down when I’m finished using it?
A. Shut it down.
According to the Environmental Protection Agency, running a computer at night is akin to leaving on about 10 lightbulbs. You turn off lamps before you go to bed. Why not do the same to your PC? That simple click saves energy and money. For every household computer you shut down, you could cut $10 to $30 off your annual electric bill. Sleep mode uses less juice than full power, but shutting down has the added benefit of increasing your computer’s functionality,. It gives your hard drive time to cool off (prolonged heat shortens its life span) and allows for automatic software updates. If you just snooze, you lose.
