Sleep and Hyper-V on your Surface Pro 3
I got a Surface 3 Pro recently and I really love the fact that I can use it as a tablet and as a normal Laptop but am not bound to carrying two devices with me. One problem I received was after installing Visual Studio which installs and activates Hyper-V automatically. Hyper-V disables the connected Stand-By mode on your Surface. No problem there but that connected stand-by is also your sleep mode and living without a sleep mode on your tablet is a real pain point.
The solution
Luckely we can easily change this behaviour by switching Hyper-V off when we do not need it with the following command:
bcdedit /set hypervisorlaunchtype off
And if we do need Hyper-V for development we can enable it again with this line of code:
bcdedit /set hypervisorlaunchtype auto
You will have to run each command in an elevated powershell as admin. Simply open Powershell rightclick on the Taskbar icon and select Run as Administrator.
