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, Power saver, and High performance—meet most people's needs. But you can modify settings for existing plans or create your own 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.
Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Power Options.
Under the plan that you want to change, click Change plan settings.
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 (mobile PC only) and when it's plugged in.
In Power Options, some of the links in the left pane open System Settings. Changes on this page 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 the computer when it wakes from sleep.
Choose what your computer does when you press the power and sleep buttons on your keyboard or mobile PC frame or, with some mobile PCs, 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.
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 mobile PCs).
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 (mobile PC only), and when it's plugged in.
Click Save changes.
For more information about system settings, go to the power options article on the Microsoft Help and Support website.
You can create your own plan and customize it to suit your needs. For example, if you frequently use a mobile PC to give presentations, you can create a plan that keeps the display turned on during the presentations and ensures that your mobile PC stays awake.
In the left pane, click Create a power plan.
On the Create a power plan page, select the plan that's closest to the type of plan that you want to create.
In the Plan name box, type a name for the plan, such as "Giving a presentation," and then click Next.
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.
Change the Turn off display after setting to Never for both On battery and Plugged in.
Change the Put the computer to sleep setting to Never for both On battery and Plugged in.
If you're using a mobile PC, 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.
The plan that you just created automatically becomes the active plan. To put a different plan into effect, select that plan.
If you created power plans that you no longer use or need, delete them. You can't delete any of the three default power plans (Balanced, Power saver, and High performance).
After you delete a plan, you can't restore it.
If the active plan is the one that you want to delete, make a different plan the active plan.
Under the plan that you want to delete, click Change plan settings.
On the Change settings for the plan page, click Delete this plan.
When prompted, click OK.
