Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I recently installed Windows Server 2012. This will serve as the dev-instance for our engineers and will be accessed in multiple time zones. I therefore plan to run this 24x7 but want to conserve energy by going to sleep mode when not in use & enable Wake-On-Magic-Packet.

Based on the previous post it appears that there is no option to sleep Win Server 2012 with Hyper-V. Since I don't care much about virtualization now, I uninstalled Hyper-V.

In addition to this, I have done the following

1) Ran powercfg -a. Don't find sleep.

2) Added [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot] "Start"=dword:00000003 to try gaining sleep - no luck!

3) Only see Shutdown and Restart in power options.

Please help me sleep and save the planet :-)

Thanks,
Ramesh

If you want to save the planet then plant trees as compensation. And pay for "green" energy. –  mailq Oct 2 '12 at 0:24

A server does not sleep. A workstation can sleep, but a sever must still be available for requests at any time. Otherwise it isn't a server.

There is a way to sleep Windows Server 8. arjunachith.blogspot.com/2010/06/…. Is there something similar for 2012? –  Ramesh Elaiyavalli Oct 2 '12 at 0:37
    
@Ramesh No. There isn't. –  mailq Oct 2 '12 at 0:38
    
@mailq : a server can serve request at specific times, not all the times. You don't answer the question. –  user162916 Mar 4 '13 at 23:49

I tried powercfg/hibernate ON in windows server 2012 Command Prompt with Admin rights. And now I see the hibernate option in "power options" in control panel.
