Page 1 of 3You’ve got a five-hour flight from Los Angeles to New York City, and one battery in your laptop. You’ve got work to do, DVDs to watch, and games to play. How are you going to get that battery to last? Well, hidden inside (and outside) your computer are lots of tricks to help you.
Dimming Your Screen
Your screen and hard drive use up more battery power than any other parts of your computer. You can dim down your screen to a point where your eyes still feel comfortable but you also save energy. On most laptops, you first dim the screen by holding down the “Fn” key (go ahead and find it because you may never have used it before). Then you look for a key on your laptop that either has a picture of a sun or a half-moon. (On my Sony Vaio that key happens to be F5.) If you find it, go ahead and hit it while still holding down the Fn key. A brightness adjustment box should show up on your screen. If you can’t find a key with a sun or half-moon on it, try hitting your various arrow keys while holding down Fn, to see if that works.
