How to enable the sleep feature on Server 2008 with Hyper-V

The sleep and hibernate features are disabled when Hyper-V is installed on a Server 2008 (R2). This is by design.

Lets start a long journey to find a workaround ..


powercfg.exe /hibernate on


–> Fail.





Disable Hyper-V Service?

I stumbled upon this blog post:

You can have Hyper-V installed but the service not started by the following registry setting:

Windows Registry Editor Version 5.00



When the computer starts, all power management features are available.

If you need a VM (for a demo for example), Hyper-V can be started with the following command:

net start hvboot

Power management will be disabled again, until the next reboot.

As I don’t need Hyper-V most of the time this is the workaround for now! The journey wasn’t that long after all!
