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

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.

The only way this can be achieved is by going into the power settings, and changing the power plan to put the computer to sleep after, say, 2 minutes. It will then sleep as desired.
