119. Help save energy and the environment by putting your monitor to sleep

You can save electricity and reduce your impact on the environment by activating your monitor’s sleep feature in Microsoft Windows XP. Activating sleep settings on just one computer may prevent considerable CO2 emissions each year. Letting your monitor sleep allows it to go into a low-power mode when you’re not using it. To wake your monitor, you simply touch your mouse or keyboard.

To set Windows XP to automatically turn your monitor off when your computer isn’t being used

1.Right-click the desktop, and then click Properties.

2.In the Display Properties dialog box, click the Screen Saver tab. Then, click the Power button.

3.In the Power Options Properties dialog box, click the Turn off monitor list, and select a time to automatically turn off your monitor. Five minutes is a realistic setting. If you have a portable computer, set the time for both Plugged in and Running on batteries.

4.Click OK twice.

Windows XP will let your monitor sleep after your computer has been idle for the specified number of minutes. To reactivate your monitor, move your mouse, or press a key. You’ll save almost as much power as if you had manually turned your monitor off, but you won’t have to press your monitor’s power button.
