Window Home Server is built on Windows Server 2003 and thus doesn’t have any power savings turned on by default. While there are some add-ins to put WHS to sleep/hibernate, you should go into the Power Options and turn on the “Server Balanced Processor and Performance” scheme to at least minimize CPU power consumption.
- Make a Remote Desktop connection to your WHS machine.
- Click the Start button.
- Click Control Panel, and then click Power Options.
- On the Power Schemes tab, select Server Balanced Processor Power and Performance.
- Consider changing the settings for Turn off hard disks, too.
- Click OK.
