Configure power management in managed guest sessions on ChromeOS devices

Jump To

This document will help IT administrators configure power management in managed guest sessions on ChromeOS devices.

Managed guest sessions allow ChromeOS devices to be shared securely and efficiently without requiring individual user sign-ins. These sessions are centrally managed, giving IT admins control over how the devices behave, including how they manage power. Setting up power management in these sessions ensures that devices use energy wisely, preserve battery health, and optimize device performance to meet specific operational needs.

To manage this effectively, IT administrators can use Hexnode’s Power Management feature for managed guest sessions. This allows to remotely configure and enforce power-related settings across multiple devices in the organization.

Note:


Some of the power management settings are supported only on the following device types:

  • 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

To configure power management in managed guest sessions on ChromeOS devices,

  1. Login to the Hexnode UEM portal.
  2. Go to the Policies tab. Click on New Policy to create a new policy or modify an existing one.
  3. Provide the name and description (optional) for the policy.
  4. Navigate to ChromeOS > Managed Guest Session > Power Management. Click on Configure.
