3.4 Power Management Policy

The Power Management policy allows you to configure the Power Management settings on the managed devices by creating a power scheme. It lets you configure the plugged in and battery power management settings and assign them to a device or a user.

  1. In ZENworks Control Center, click the Policies tab.

  2. In the Policies list, click New, then click Policy.

    or

    In the Policy Tasks, click New Policy.

    The Select Platform page is displayed.

    The Select Policy Category page is displayed.

  4. Select Windows Configuration Policies, then click Next.

  5. Select Power Management Policy as the Policy Type, then click Next.

  6. In the Define Details page fill in the following fields:

    Policy Name: Provide a name for the policy. The policy name must be different than the name of any other item (group, folder, and so forth) that resides in the same folder. The name you provide displays in ZENworks Control Center.

    Folder: Type the name or browse to and select the ZENworks Control Center folder where you want the policy to reside. The default is /policies, but you can create additional folders to organize your policies.

    Administrator Notes: Provide a short description of the policy’s content. This description displays in ZENworks Control Center.

  7. Click Next to configure the power settings for a managed device.

  8. In the Add Power Scheme Settings page fill in the following fields:

    Scheme Name: The policy name specified on the Define Details page is automatically displayed. You can either retain the policy name for the scheme or specify a new scheme name. ZENworks 11 creates a scheme with the specified name on the managed device.

    Scheme Description: Provide a description for the power scheme. The description is displayed as a tooltip for the power scheme on the managed device.

    NOTE:

    • We recommend that you configure the power scheme duration in the following descending order: System Hibernation > System Standby > Hard Disks > Monitor.

    • The values of System Standby and System Hibernation are interdependent. If you choose to set the state of these settings to Not Configured, in such a case, the other setting can only be set to either Never or Not Configured. This is to ensure that the 'Standby Timeout' is always lesser than the 'Hibernate Timeout'.

      For example, if you set a duration for the System Standby value and then set the System Hibernation value to Not Configured, the System Standby value automatically changes to Not Configured.

    • When you apply power management settings on a Windows XP managed device, the scheme name is displayed in the settings panel of the Windows Power Options console only for a system user.
