Different computers have different power-management requirements and abilities. You might want the monitor on your main desktop computer to shut down after a few minutes of idleness, but you might also want the computer itself to "stay awake" constantly. With a portable computer, you might want everything to go to sleep after a few minutes of idleness. You can adjust a power plan so that the computer does these things automatically, or you can make the adjustments manually by specifying what you want to happen when you press a power button or close the lid of a portable computer. For protection, you can also require that only you can unlock your account when the computer wakes up from Sleep mode.
Click the Start button, type power in the Search box of the Start menu, and click Power Options to display the Power Options window.
In the Edit Plan Settings window that appears, examine the settings. If you want to modify a setting, specify a new value.
If you want to make more detailed changes—for example, to specify when the hard disk is to be turned off—click Change Advanced Power Settings. In the Power Options dialog box that appears, make the changes you want, and click OK.
- In the Power Options window, click Choose What The Power Buttons Do (or click Choose What The Power Button Does, if you’re using a desktop computer) to display the System Settings window.
Specify what you want to happen to the items available on your computer when you press a button or close the computer’s lid.
Click an option to specify whether you want to require a password when the computer wakes up from Sleep mode.
Tip
You can quickly switch power plans or access the Power Options window by clicking the Power icon, if it’s displayed, on the taskbar.
