Power Management Instructions

When enabled, power management places your computer (including the monitor, hard drives and other parts) into a low-power “sleep” mode after a period of inactivity. A simple touch of the mouse or keyboard “wakes” everything in seconds. Power management features are standard in Windows and Macintosh operating systems.

The use of power management can reduce energy consumption and cooling costs, reduce noise, and prolong the battery life of laptop PCs. And when your PC consumes less power, you reduce your impact on the environment.

To improve the power efficiency of your PC, the Climate Savers Computing Initiative recommends the following power management settings:

  • Monitor/display sleep: Turn off after 15 minutes or less
  • Turn off hard drives/hard disk sleep: 15 minutes or less
  • System standby/sleep: After 30 minutes or less

If you set those times to shorter periods (e.g. sleep after 20 minutes or less) you might save even more, depending on the pattern of your computer use.

Instructions for enabling power management vary by operating system. You can download a printable PDF with instructions for enabling power management in Windows 7, Windows Vista, Windows 2000/XP, Windows 98, Windows 95, Windows ME, and Mac OS 9.
