Use Energy-Saving Settings on your Computer


Learn how to use your computer's energy-saving features to help conserve energy and reduce costs.   By shutting down your desktop computer when you leave for the day and using these energy-saving features when you're away from your desk (unless otherwise instructed by your network administrator) you can help us conserve energy and reduce unnecessary costs.
