Nearly all PCs installed with Windows 7 will initially have power management enabled with Energy Star recommended settings or better. However, sometimes power management is disabled or made less effective by other users or system administrators who manage your PC for you.
Although power management settings can be changed through the Control Panel, we recommend you use the “Improve power usage” troubleshooting tool in Windows 7 to optimize energy savings. Follow the step-by-step directions below or view a video of the extensive Windows 7 power management features at http://technet.microsoft.com/en-us/windows/ee524728.aspx
- Select Start. In the Search Programs and Files box, type “troubleshoot” and select Troubleshooting.
- Under the System and Security heading, click Improve power usage.
Click Next to optimize your computer power management settings, including a 10-minute display blanking timeout and 30-minute automatic sleep setting.
- Click Close to exit.
Power settings can be optimized further by going directly to the Power Options setting. Click Start and type “power options” in the Search Programs and Files box.On a mobile PC, this can be accessed directly by clicking on the power icon in the system tray (typically located on the bottom right of the screen) and selecting More power options.
Click Change options on the currently selected plan.
Select the desired timeouts and screen brightness (if using an integrated display). Recommended timeouts are shown below. Click save when done and close the power options control panel.
