If you install Visual Studio 2013, there is a conflict between Connected Standby and Hyper-V. Connected Standby is no longer operational. This article provides a work-around.
The Surface Pro 3 is the only Surface “Pro” device that supports Connected Standby. Surface Pro (original) and Surface Pro 2 do not support this power management protocol.
Developers who install Visual Studio 2013 may notice that after installing VS 2013 that their Surface Pro is no longer performing in the same manner and that Connected Standby no longer works. This occurs because Connected Standby is not supported on a system running Hyper-V virtualization.
The emulator for Windows 8 Phone development in Visual Studio 2013 requires Hyper-V.
A current work-around to restore Connected Standby functionality is to use BCDEDIT to turn Hyper-V off when not needed and on again when you need to use the VS 2013 emulator to test Windows Phone Applications. If you are not developing phone apps, you can turn Hyper-V off and leave it off.
Steps to Turn Off Hyper-V:
- If you have installed Visual Studio 2013, verify that Connected Standby is on or off by opening an administrative command prompt and typing
As you can see in the screen capture below, Standby (Connected) is NOT supported. (The entry"The hypervisor does not support this standby state" indicates that Hyper-V is active and the Connected Standby is not available).
2. Turn Hyper-V off by typing the following into the command window:
bcdedit /set hypervisorlaunchtype off
3. Restart your Surface Pro 3 (You must restart for the new configuration to become active)
After the Surface Pro 3 has been restarted, Connected Standby should be active again. You can check this by opening an administrative command prompt and typing
As you can see, Standby (Connected) is now available which is the default configuration for Surface Pro 3.
Steps to turn on Hyper-V:
1. Open an administrative command prompt and type:
bcdedit /set hypervisorlaunchtype auto
2. Restart your Surface Pro 3
After restarting, Hyper-V will again be active (and Connected Standby will no longer function). You will be able to use the Phone Emulator in Visual Studio 2013.
