Not the best work around for getting "sleep" back wiht Hyper-V
For those trying to live the dream and run Hyper-V on your laptop and want the functionality of your power mngt back.
I create a reg file and flip back and forth.
Disable:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot]
"Start"=dword:00000003
Enable:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot]
"Start"=dword:00000000
This works well and allows me to sleep/hibernate when I am mobile. The downside is you have to reboot but the dual boot method requires that as well and now I only have to worry about running 1 OS.
