Power management in System Center 2012 Configuration Manager enables you to apply power plans that are supplied with Configuration Manager to collections of computers in your hierarchy, or to create your own custom power plans. Use the procedure in this topic to apply a built-in or custom power plan to computers.
You can only apply Configuration Manager power plans to device collections.
If a computer is a member of multiple collections, each applying different power plans, then the following actions will be taken:
Power plan: If multiple values for power settings are applied to a computer, the least restrictive value is used.
Wakeup time: If multiple wakeup times are applied to a desktop computer, the time closest to midnight is used.
Use the Computers with Multiple Power Plans report to display all computers that have multiple power plans applied to them. This can help you discover computers that have power conflicts. For more information about power management reports, see How to Monitor and Plan for Power Management in Configuration Manager.
Power settings configured by using Windows Group Policy will override settings configured by Configuration Manager power management.
Use the following procedure to create and apply a Configuration Manager power plan.
In the Configuration Manager console, click Assets and Compliance.
In the Assets and Compliance workspace, click Device Collections.
In the Device Collections list, click the collection to which you want to apply power management settings and then, in the Home tab, in the Properties group, click Properties.
In the Power Management tab of the <Collection Name> Properties dialog box, select Specify power management settings for this collection.
You can also click Browse and then copy the power management settings from a selected collection to the selected collection.
In the Start and End fields, specify the start and end time for peak (or business) hours.
Enable Wakeup time (desktop computers) to specify a time when a desktop computer will wake from sleep or wake from hibernate to install scheduled updates or software installations.
Power management uses the internal Windows wakeup time feature to wake computers from sleep or hibernate. Wakeup time settings are not applied to portable computers to prevent scenarios in which they might wake when not plugged in. The wake up time is randomized and computers will be woken over a one hour period from the specified wakeup time.
If you want to configure a custom power plan for peak (or business) hours, select Customized Peak (ConfigMgr) from the Peak plan drop-down list, and then click Edit. If you want to configure a power plan for non-peak (or nonbusiness) hours, select Customized Non-Peak (ConfigMgr) from the Non-peak plan drop-down list, and then click Edit.
You can use the Computer Activity report to help you decide the schedules to use for peak and non-peak hours when you apply power plans to collections of computers. For more information, see Computer Activity Report in the topic How to Monitor and Plan for Power Management in Configuration Manager.
You can also select from the built-in power plans, Balanced (ConfigMgr), High Performance (ConfigMgr) and Power Saver (ConfigMgr), and then click View to display the properties of each power plan.
You cannot modify the built-in power plans.
In the <power plan name> Properties dialog box, configure the following settings:
Name: Specify a name for this power plan or use the supplied default value.
Description: Specify a description for this power plan or use the supplied default value.
Specify the properties for this power plan: Configure the power plan properties. To disable a property, clear its check box. For information about the available settings, see Available Power Management Plan Settings in this topic.
Enabled settings are applied to computers when the power plan is applied. If you clear a power setting check box, the value on the client computer is not changed when the power plan is applied. Clearing a check box does not restore the power setting to its previous value before a power plan was applied.
Click OK to close the <power plan name> Properties dialog box.
Click OK to close the <Collection Name> Settings dialog box and to apply the power plan.
The following table lists the power management settings available in Configuration Manager. You can configure separate settings for when the computer is plugged in or running on battery power. Depending on the version of Windows you are using, some settings might not be configurable.
Power settings that you do not configure will retain their current value on client computers.

Allow standby state when sleeping action
Enables the computer to be on standby, which still consumes some power, but enables the computer to wake faster. Possible values are:
Required idleness to sleep (%)
Specifies the percentage of idle time on the computer processor time required for the computer to enter sleep.
Enable Windows wake up timer for desktop computers
