Set up power management settings on ChromeOS devices

The document assists you in configuring power management settings for ChromeOS devices from the Hexnode UEM console.

Power Management settings on ChromeOS devices define how the system balances performance and battery life when running on battery or connected to a power source. For organizations managing ChromeOS devices, configuring power settings can reduce energy consumption, extend battery health and optimize device usage based on operational requirements.

Hexnode’s Power Management policy provides different settings to ensure that your ChromeOS devices’ power and performance management align with your organization’s requirements.

Configure power management settings

Follow the below steps to configure the power management settings for ChromeOS:

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 ChromeOS and select Power Management under Configurations.
5. Click on Configure.

Settings	Description	Supported OS versions/device types
Screen wake lock	Prevents apps and extensions from keeping the screen on. When unchecked, the device remains powered on without necessarily keeping the screen active.	ChromeOS 28+
Shift power to battery during peak hours	Reduces AC power usage by switching the device to battery during specified peak hours. You can enable this setting for specific days (Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday). For each selected day, set the following times: Shift to Battery at: Time when the device should switch from AC to battery power. Shift to Power at: Time when the device should switch back to AC power. Note: Shift to Power time should be greater than Shift to Battery time and less than Start Charging time. Start Charging at: Time when the device should begin charging the battery.	Dell Latitude 5400 Chromebook Enterprise Dell Latitude 5300 2-in-1 Chromebook Enterprise Dell Latitude 7410 Chromebook Enterprise Dell Latitude 7410 2-in-1 Chromebook Enterprise
Minimum battery threshold	Specify the minimum battery level required for shifting to battery power during peak hours. This option is available only if “Shift power to battery during peak hours” is enabled. The value should be between 15 and 100.	ChromeOS 75+
Device charging mode	Specifies the charging mode for the device to optimize battery performance: Standard charging Adaptive charging Fast charging Charge devices connected to an external power source Custom Charging: Define when the device should start and stop charging by setting custom battery thresholds. The value for start charging percentage should be between 50 and 100. Note: The stop charging setting must be at least five percentage points above the start charging setting.	ChromeOS 75+
Boot on AC	Determines whether the device powers on automatically when plugged into an external power source.	ChromeOS 75+
Charging sound	Enables or disables the sound played when the device is connected to an external power source.	ChromeOS 117+
Low battery sound	Enables or disables the sound played when the battery reaches a critical level or the remaining time is low.	ChromeOS 117+
Enable USB power share	Allows the ChromeOS device to charge connected devices through USB while the system is in sleep or shutdown.	ChromeOS 75+
Device lid close action	Specifies what happens when the device lid is closed: Suspend: Device enters sleep mode when the lid is closed. Log the User Out: Logs the user out when the lid is closed. Shutdown: Device shuts down when the lid is closed. Do Nothing: No action is taken when the lid is closed.	ChromeOS 26+
Idle device management	Specify the power management settings during idle time. These settings should be configured individually for when the device is On AC power and On battery. Idle Warning: Configure the delay before the device displays a warning ahead of going idle. The value should be between 0-2000000 seconds. Note: This setting will have no effect when the Idle device settings is configured as ‘Suspend’ or ‘Do nothing’. Screen Dim: Set the delay before the screen dims. The value should be between 0-999999 seconds. Note: The screen dim delay cannot be larger than the values set for Idle Timeout, Screen off, Screen lock delay on AC, or Screen lock delay on battery. Screen Off: Set the delay before the screen turns off. The value should be between 0-999999 seconds. Note: The screen off delay cannot be larger than the values set for Idle Timeout, Screen lock delay on AC, or Screen lock delay on battery. Idle Timeout: Specifies how long the device remains idle before entering idle mode. The value should be between 0-999999 seconds. Idle device settings: Specify the action the device should take after reaching the configured idle timeout. Suspend: Device enters sleep mode when the lid is closed. Log the User Out: Logs the user out when the lid is closed. Shutdown: Device shuts down when the lid is closed. Do Nothing: No action is taken when the lid is closed.	ChromeOS 35+
Device not idle when audio plays	If enabled, this option prevents the device from entering idle mode while audio is playing.	ChromeOS 26+
Device not idle when video plays	If enabled, this option prevents the device from entering idle mode while video is playing.	ChromeOS 26+
Smart dim	Automatically dims the screen based on user activity. If disabled, the administrator can configure when the screen dims based on the following settings: Presentation Screen Dim Delay Scale: Sets the delay time before the screen dims when the device is idle in presentation mode. (Value should be greater than 100). User Activity Screen Dim Delay Scale: Defines the delay time for dimming the screen after user activity. (Value should be greater than 100).	ChromeOS 70+
Screen brightness on AC	Sets the screen brightness level when the device is connected to AC power. The value should be between 0 and 100.	ChromeOS 72+
Screen brightness on battery	Sets the screen brightness level when the device is using battery power. The value should be between 0 and 100.	ChromeOS 72+
Screen lock delay on AC	Defines the time without user input before the screen locks while on AC power: 30 seconds 1 minute 2 minutes 5 minutes 10 minutes 15 minutes 30 minutes Never	ChromeOS 35+
Screen lock delay on battery	Defines the time without user input before the screen locks while on battery: 30 seconds 1 minute 2 minutes 5 minutes 10 minutes 15 minutes 30 minutes Never	ChromeOS 35+

Associating policies with Organizational Units

To assign ChromeOS policies:

1. Navigate to Policy Targets > Domains/OUs.
2. Click + Add Domain/OUs.
3. From the list of available domains, select your integrated Google Workspace domain.
4. The parent Organizational Unit (OU) appears with a briefcase icon to distinguish it from domains.
5. Click the dropdown next to the parent OU to view its child OUs.
6. Select the OUs that include the target devices and click OK.
   
   Note:

   
   Note that a policy assigned to a parent OU will automatically apply to all its child OUs.
   

7. Click Save to associate the policy with the selected Organizational Units.

What happens at the device?

After associating the policy with the relevant Organizational Units (OUs), the configured power management settings will be applied to the ChromeOS devices in those OUs, and the devices will behave as defined in the policy.
