So I recently installed Visual Studio 2013 on my Surface Pro 3 and then found that I could no longer put it to sleep.
VS 2013 enables Hyper-v in Windows which developers use to test apps in other Operating Systems (such as Windows Phone). The problem is that Hyper-v conflicts with the advanced power management features (Connected Standby) on the Surface Pro 3.
While Hyper-v can be turned on and off this requires a reboot – and the Surface Pro 3 can only be shutdown, restarted or hibernated while Hyper-v is running.
The work-around is to manually enable and disable hyper-v and then reboot.
To disable Hyper-v open an Administrator Command Prompt, enter this command and then reboot:
bcdedit /set hypervisorlaunchtype off
Hyper-V can be enabled again with this command (which also requires a reboot):
The Type cover for the Surface Pro 3 is a little different than your regular laptop keyboard.
The function keys dim and brighten the back-light on the Type cover and open Windows functions such as Search, Sharing, Devices and Settings (amongst other things).
This can be pretty helpful – depending on what you are doing – but this default configuration means that one of my most used keyboard shortcuts Alt + F4 is not available.
The first solution is to just use Fn + Alt + F4 instead.
Otherwise pressing and holding the Fn key and then pressing Caps toggles the functionality of the top row of keys on the Type cover so that you can use Alt + F4. This is a toggle though – once you can use Alt + F4 you have to toggle back to use the default (pictured) functionality of these keys.
