computer

Hi every one
I have an advice for you people from my class. I want you know that never leave your computer open if you are not using it. First, when you leave the computer open, you use electricity. Specialy Deskopt, they use a lot of energy. Next, when you leave your computer open with out using it, any chock electry can makes it has problem. Now you will calle the compagny to fix it ,or you`ll give some body who is expert to fix it for money. when it happened you should spend money for that. However you can have this money to do another thing. Finally, your computer can have take virus when it is staying open for ever. The computer becomes very slow. Sincerely my friends don`t let your computer opens if you`re not using it. That cause you spend money to fix your computer.
