Power Options implemented on all IT Windows XP domain workstations.

Thursday, May 28th, 2009

We implemented GPO policy scripts on all IT Windows XP workstations that are part of the STB domain.

The script implements the following settings:
1. Monitor time out after 30 minutes if running on AC Power.
2. Disk time out after 60 minutes if running on AC Power. The disks are completely stopped.
3. System Standby after 120 minutes if running on AC Power.

A further implementation will be to Hibernate after 180 minutes if running on AC Power.

The current script will not change Power Schemes on any Vista or later Operating Systems. For Windows Vista and later Operating Systems, we will implement GPO policy templates. This will be implemented at a later stage.
