Power Management Instructions

When enabled, power management places your monitor, hard drives and computer into a low-power “sleep” mode after a period of inactivity. A simple touch of the mouse or keyboard “wakes” the computer, hard drive and monitor 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

Instructions for enabling power management vary by operating system. Click the links to the right for detailed instructions by operating system.

You can also download a printable PDF with instructions for enabling power management in all of the above operating systems.


Did you Know?

U.S. college students could save more than 2.3 billion kilowatt hours
per year of electricity by enabling power saving features on their
desktop PCs. That equals an annual savings of more than $200 million in
energy costs and a 1.8 million-ton reduction of CO2 emissions from the
operation of computers –equivalent to taking more than 350,000 cars off
the road.7
