In Power Options, some of the links in the left pane open System Settings. When you make changes on this page, changes are automatically made to all of your power plans. By changing system settings, you can do the following:
• Help secure your computer by requiring a password to unlock it when it wakes from sleep.
• Choose what your computer does when you press the power and sleep buttons on your keyboard or laptop frame or, with some laptops, when you close the lid. For example, when you press the power button, the computer can either do nothing or it can shut down.
If the computer supports sleep and hibernate, pressing the power button can also put the computer into one of those power-saving states.
1. Open Power Options by clicking the Start button, clicking
Control Panel, clicking System and Security, and then clicking
2. In the left pane, click Require a password on wakeup,
Choose what the power button does, or Choose what closing the lid does (available only on laptops).
3. On the Define power buttons and turn on password protection page, choose the settings that you want to use when your computer is running on battery (if applicable), and when it's plugged in.
4. Click Save changes.
You may change the settings to turn off your monitor (display) under Power Options > Edit Plan Settings > Turn off the display.
