Cannot Use Sleep Mode on Windows 2008 R2 With Hyper-V

This is not RDS specific but it is annoying. I have a laptop on which I run Windows Server 2008 R2. I use this laptop to run Hyper-V and VMs so I can do demos and testing. I also use this laptop for personal use. I would like to be able to take advantage of power settings like sleep mode, but because I run the Hyper-V hypervisor, I cannot (see: http://support.microsoft.com/kb/913405).

Here is a way around it: turn off the hypervisor when you boot by making a “no hypervisor” boot option.

IMPORTANT: THIS IS NOT SUPPORTED!!! (but it works for me):
1. At the command prompt, type the following: bcdedit /copy {default} /d "No Hypervisor"
         (this creates the extra boot option).

     The above command should say: The entry was successfully copied to {guid}.

3. Copy that guid to the clipboard including the brackets.

4. Now, type the following command: bcdedit /set {PLACE-GUID-HERE} hypervisorlaunchtype off 
         (this stops the hypervisor from running)
Now when you boot, you can use Sleep mode.
