Manage Your Power
You can automatically save power and money when using your computer by using the following settings for the power management features of your computer.
We recommend following the power management settings for your computer:
- Monitor/Display Sleep: Turn off after 15 minutes (or less)
- Turn Off Hard Drives/Hard Disk Sleep: After 15 minutes (or less)
- System Standby/Sleep: After 30 Minutes (or less)
When your computer is in standby/sleep mode, all it takes is to press a key or wiggle the mouse to wake it back up in seconds, so you don't lose any valuable work or play time.
Change Power Management Settings
Modern computer operating systems come with power management set to conserve power. If you need to change those settings don't forget to change them back to the original power-save settings.
Instructions for Windows 7 and 8
- Click on Start.
- On the right hand side of the menu select Control Panel (Windows 8 users, type Control Panel into the search bar and click to open). Control Panel has two views.
- If you are in Themed View double click on Hardware and Sound and select Power Options.

These can be set for when the computer is plugged in and when it is on battery (if you have a laptop).

Instructions for Macs

The U.S. Environmental Protection Agency's ENERGY STAR program recommends setting computers to enter standby or hibernate after 15 to 60 minutes of inactivity. To save even more energy, set monitor displays to enter sleep mode after 5 to 20 minutes of inactivity. The lower the setting, the more energy you save.
