Maybe this a solution, but I also doubt that this is the whole story, since this was never an issue earlier. This was never a problem and teamviewer stayed connected the whole day.

But I don't think that this is causing the issue as I usually close the lid of my surface book, which switches off the display aswell. If you set it to 0, then the Surface's display will turn off after the amount of time specified in the Turn off the display setting in the Control Panel's Power Options - usually this is 10 minutes.Īs to why this seems to have changed within the past few days - my guess is that a recent update from Microsoft may have changed this behaviour on these wrote: Now that this setting is no longer hidden, you can change it to something longer, or else set it to 0 which disables it completely.

In summary, if you carefully follow the instructions there (and bearing in mind that editing the Registry is risky business), you'll end up with a new Display setting called Console lock display off timeout, which is located in the Advanced Power Settings in the Control Panel. This previously-hidden setting causes Windows to turn off the display (by default) 60 seconds after it's locked, and on a Surface tablet this means it enters Modern Standby mode. Rather than repeat the instructions, I'll point you to the article that contains the solution, and give credit where credit's due: According to my research, this is caused by a setting in Windows 10 which is hidden by default, but which you can unhide and change with a simple edit to the Windows Registry. So the issue here is why the screen is turning off after the Surface is locked. You can learn more about the Windows 10 Modern Standby feature in this video from Microsoft.) As a result, programs like TeamViewer are not able to stay connected. (The fact that TeamViewer goes offline is expected behaviour. When the Surface's display turns off, it enters Modern Standby mode, which is a new and more advanced sleep state. Specifically, when I lock the device, the screen will turn off after about 40-60 seconds, and the device will go offline on my TeamViewer Computers & Contacts list. I've noticed this happening on my own Surface Pro 3 as well.
