You should turn your computer off every night....I don't know about the health of your computer -- but for the health of your pocketbook. Computers draw current. In fact, if your computer is plugged into a power strip, you should turn the whole strip off when you are not using the computer. Those strips use electircity even when nothing is turned on.

This goes for electical chargers as well.

Good for your electric bill, your pocket book and the planet!
