You can save electricity and money and help protect the environment by activating your monitor’s "sleep" feature in Windows XP. Activating sleep settings on just one computer prevents approximately 300 pounds of CO2 emissions each year.

Putting your monitor to "sleep" means allowing 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 activate monitor power management ("sleep") settings:

1. Click Start, and then click Control Panel.
2. Double-click the Display icon.
3. Click the Screen Saver tab.
4. In the Monitor Power box, click the Power button.
5. In the Turn off monitor box, select After 10 mins, or choose a time that you find appropriate.
