Enable Sleep / Hibernate with Hyper-V

From Virtual PC ...

When you enable the Hyper-V role on Windows Server 2008 support for sleep /
hibernate will be disabled.

Q. Is there some way that I can "hack" the system to re-enable sleep /
hibernate with Hyper-V? A. No.

I am using Windows Server 2008 R2 as my primary laptop with Hyper-V ... I have a partial solution to this problem.

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

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot]"Start"=dword:00000003

Now, when I start my laptop i have full access to the power management fucntionality.

If I need to demo a VM, I can start Hyper-V with the command

net start hvboot

Power management is then disabled again until the next reboot.
