Activating power management in enterprises: replicating from a template HD image

If you replicate hard drives from a template image when you upgrade operating systems and/or roll out new hardware, enabling sleep settings in the template image will ensure that all computers receive these settings.

For detailed, illustrated instructions on manually activating power management settings in the master template hard drive image, select your operating system below.

By default in Windows XP and Windows 2000, accounts that are not in the Local Administrators or Power Users groups don’t have the "rights" (privileges) to change Power Management settings. If you want to revoke the right to change these settings from Power Users or Local Administrators, you can remove the "Set Value" privilege from — or add a deny of the "Set Value" privilege to — the following registry key. Denying or removing all rights will prevent users from being able to set the values.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Controls Folder\PowerCfg\PowerPolicies

In Windows Vista, network administrators can manage power management settings — and control user privileges for changing power management settings — by using a Local or Domain Group Policy.
