Configure power management settings for Windows devices

Power management refers to the practices followed to minimize energy consumption on devices. These practices can include configuring the idle time of the device, turning on the energy saver, and even more. It ensures energy efficiency, cost savings, and an extended lifetime of the device. The devices can be configured to manage power settings both when running on battery and when plugged in. With Windows Power policy, an IT Admin can configure devices as per the organization’s requirements.

Configure Power management settings

Follow the below steps to configure the Power policy:

1. Login to your Hexnode UEM portal.
2. Navigate to the Policies tab.
3. Click on New Policy to create a new one or click on any policy to edit an existing one. Enter the Policy Name and Description in the provided fields.
4. Navigate to Windows and select Power under Configurations.
5. Click on Configure.

Hibernate

Enable this option to allow the system to Hibernate. By default, this option is enabled.
To disable, click Yes on the dialogue box that appears on unchecking ‘Hibernate’. If not enabled, the system will not be able to hibernate. Any settings that cause the device to hibernate will be set to default and the ‘Hibernate’ option will be unavailable for some of the configurations.

Hybrid Sleep

This setting ensures that the device resumes the current session as if from sleep. In case of power failures or any mishaps that cause the system to shut down, the device resumes as if from Hibernate. Enabling this setting makes sure that the current session is not lost.

Settings	Description
Enable	System enters a Hybrid mode, and the current session is retained.
Disable	System does not enter Hybrid mode.

Turn on Energy Saver when charge level is at

When the device is running on battery, this setting determines the charge level at which the Energy Saver gets activated. When the device is plugged in, it determines the charge level that the device must reach for the Energy Saver to be deactivated. If the charge level of the device is higher than the value configured under ‘Turn on Energy Saver when charge level is at’, Energy Saver does not get activated.
The acceptable range of values is 0 to 100. If the value is not configured, the default value, 0 is configured, which allows the user to control this setting.

Upon pressing Sleep button

This setting specifies the function of the Sleep button that is available on the keypad.

Settings	Description
Not Configured	Allows the user to change the setting.
Take no action	Pressing the sleep button has no effect.
Sleep (Default)	System enters the Sleep state.
Hibernate	System enters a state of Hibernation.
Shut down	System is shut down.

Notes:

• Configuring this option on devices not having the sleep button has no effect on the device.
• The Sleep button might not work as intended when configured to Shut down on some devices.

Upon closing the lid

This setting specifies the action that occurs when the lid of a mobile PC is closed.

Settings	Description
Not Configured	Allows the user to change the setting.
Take no action	Closing the lid of the system has no effect.
Sleep (Default)	System enters the Sleep state.
Hibernate	System enters a state of Hibernation.
Shut down	System is shut down.

Upon pressing Power button

This setting specifies the function of the Power button on the keypad.

Settings	Description
Not Configured	Allows the user to change the setting.
Take no action	Pressing the power button has no effect.
Sleep (Default)	System enters the Sleep state.
Hibernate	System enters a state of Hibernation.

Unattended Sleep after

This setting specifies the period of inactivity after which a device that was in sleep wakes up due to a timed event and goes back to sleep when left unattended.

Notes:

• The setting is not available on Windows devices by default. The following command needs to be run on Windows PowerShell to configure it on the device end:
  Configure Unattended Sleep after

  Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 -Name Attributes -Type DWord -Value 2

  1	Set-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 -Name Attributes -Type DWord -Value 2

• If the Windows Screensaver policy is configured, the device does not turn off irrespective of the time configured in Unattended Sleep after as the screensaver is always enabled, and the device cannot enter a Sleep state.

6. Click Save.

Associate the Power policy with Windows devices

If the policy has not been saved,

1. Navigate to Policy Targets > +Add Devices.
2. Choose the target devices and click Ok. Click Save.

If the policy has been saved,

1. Go to the Policies tab and choose the desired policy.
2. Click on the Manage drop-down and select Associate Targets.
3. Choose the target entities and click Associate.
