How to enable “Sleep” for Windows 2012 server

windows-server-2012

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 24×7 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.
