I've been using a Windows Server OS as my laptop / desktop for many years by now. Currently, I am using Windows Server 2008 R2 as my primary laptop. When I added a Hyper-V role I discovered that "Sleep Mode" on my laptop just stopped working.
After some tests and investigations, I've come up with a partial solution to this problem. The trick to use a Sleep Mode on a system where a Hyper-V installed is to have Hyper-V NOT started. To set a Hyper-V to "Manual Start", I did a script with a following registry setting: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hvboot]"Start"=dword:00000003 After this small change, I get my Sleep mode working again on my laptop and when I need to use a Hyper-V functionality I'm starting Hyper-V with the command:
Net start hvboot
Note: Power management is then disabled again until the next reboot. |
