A power plan is a collection of hardware and system settings that manages how your computer uses and conserves power. Power plans can save energy, maximize system performance, or balance energy conservation with performance. The default power plans—Balanced and Power saver—meet most people's needs. But you can modify settings for existing plans or create your own plan.

To change settings for a single plan

You can change the following settings for individual power plans:

  • Set your computer to go to sleep after a specified period of inactivity. For more information, see Turn off a computer: frequently asked questions.

  • Adjust the brightness of your display.

  • Choose when to turn off the display during periods of inactivity.

  1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  2. Under the plan that you want to change, click Change plan settings.

  3. On the Change settings for the plan page, choose the display and sleep settings that you want to use when your computer is running on battery (if applicable) and when it's plugged in.

To change settings that affect all of your power plans (system settings)

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 Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  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.

To create your own plan

You can create your own plan and customize it to suit your needs. For example, if you frequently use a laptop to give presentations, you can create a plan that keeps the display turned on during the presentations and ensures that your computer stays awake.

  1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  2. In the left pane, click Create a power plan.

  3. On the Create a power plan page, select the plan that's closest to the type of plan that you want to create.

  4. In the Plan name box, type a name for the plan, such as "Giving a presentation," and then click Next.

  5. On the Change settings for the plan page, choose the display and sleep settings that you want to use when your computer is running on battery and when it's plugged in.

    To keep your display turned on during presentations

    • Change the Turn off display after setting to Never for both On battery and Plugged in.

    To keep your laptop awake during presentations

    • Change the Put the computer to sleep setting to Never for both On battery and Plugged in.

  6. Click Create.

    If you're using a laptop, your plan appears under Plans shown on the battery meter. If you're using a desktop computer, your plan appears under Preferred plans. The plan that you based your new plan on is moved, and appears under Additional plans.

Note

  • The plan that you just created automatically becomes the active plan. To put a different plan into effect, select that plan.

To delete a plan

If you created power plans that you no longer use or need, delete them. You can't delete Balanced, Power saver, High performance, or the plan that you're currently using (the active plan).

Warning

  • After you delete a plan, you can't restore it.

  1. Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

  2. If the active plan is the one that you want to delete, make a different plan the active plan.

  3. Under the plan that you want to delete, click Change plan settings.

  4. On the Change settings for the plan page, click Delete this plan.

  5. When prompted, click OK.
