STEP THREE (Saving Battery Power by Putting Your Display to Sleep)


It's helpful to know multiple ways to lengthen the life of your battery (especially if you're using your PowerBook/iBook on a flight). First, you need to determine which activities drain your battery the most. One of the worst offenders of battery drain is the display (also known as your monitor). Hey, it takes a lot of juice to run that big bright display, so it only makes sense that if you're not using your computer for a few minutes, you'll want that display to turn itself off, even before your computer goes to sleep. You can set the time for your display to "go to sleep" in the same place where you set your entire computer to go to sleepunder System Preferences, in the Energy Saver section. If you look under the "Put this computer to sleep…" slider, you'll see another slider that says, "Put the display to sleep when the computer is inactive for." Drag this slider to adjust the duration that your display is active. Choose a length that is less than the sleep time for your system; you want the display to sleep before the computer does to preserve the battery charge. For example, if you have the computer set to sleep at 15 minutes, you might want the display to sleep after only 5 minutes of inactivity. Don't worrythe display wakes up even faster than when the computer itself is asleep, so having the display sleep is even less of bother. To get the display to spring back to life, just press a key or move/click with the scrolling touchpad. Note: Because the screen saver can conflict with your display going to sleep, you might want to turn it off. Just click on the Desktop & Screen Saver icon in the System Preferences window, and when the Screen Saver options appear, drag the slider to the right (toward Never).
