This solution was provided by the user who reported the issue on Microsoft Community forums at first place.
It does sound a little strange for us, and we didn’t test if it works, but he claims that it solved the problem for him, so if performing a two-button reset didn’t work, you can give his solution a try.
After doing this, as our friend from Community forums says, various permission errors will occur, but you should ignore them, and just restart your computer again.
After that, everything should get back to normal, and you should be able to detach your Surface Book from the keyboard without any problems.
If your Surface Book keyboard becomes unresponsive, you can fix it by following this handy guide.
3. Manually detach the keyboard
Before we start, we have to mention that this solution is potentially dangerous and by performing it, you might permanently damage your device.
We’re not responsible for any damage that can occur to your device as a result of this solution.
According to users, if you’re unable to detach Surface Book from keyboard, you might be able to do that manually. To do that, you just need a paperclip or any other long and thin object.
To do that, you just need to put your paperclip through the sixth ventilation hole and find the hidden button that holds the keyboard. If you can’t find the button, you might need a flashlight in order to find it.
Keep in mind that you need to do that for both sides in order to release the keyboard. It’s also worth mentioning that keyboard could also snap back to its original location and become locked again, so you need to be careful.
As we already mentioned, using this solution you can cause physical damage to your device, so use it only if other solutions don’t work.
Another great thing about this solution is that you can use it even if your device is turned off, so you can detach the keyboard even if your battery is empty.
Many users reported that this solution worked for them, but if you want to try it, be extra cautious in order to avoid causing damage to your PC.
4. Make sure that your applications are using integrated graphics processor
According to users, sometimes you’re unable to detach Surface Book from keyboard because your applications are still using dedicated graphics processor.
To fix the issue, you need to open Nvidia Control Panel and set all your applications to prioritize integrated graphics.
After making this change, your applications won’t use dedicated graphics and you should be able to detach your keyboard without any problems.
Keep in mind that there’s a downside to this solution, and you might experience lower performance after setting all your applications to use integrated graphics.
If you’re using demanding applications, such as video games, for example, you can set them to use a dedicated graphics processor in order to achieve better performance.
After doing that, you should be able to detach your keyboard without any issues.
5. End the application that is using your dedicated graphics
- Press Ctrl + Shift + Esc to open Task Manager.
- Now locate the application that is using your GPU, right click it and choose End task from the menu.
If you’re unable to detach Surface Book from keyboard, it’s rather likely that a certain application is still using your dedicated graphics processor.
In our previous solution we showed you how to make all applications use a dedicated processor, however, if you don’t want to do that, you can always manually end the application that is using your GPU.
To do that, you need to use Task Manager. To end an application, just follow the steps above.
After ending the application, you should be able to detach the keyboard without any problems.
Keep in mind that this isn’t a permanent solution, so you’ll have to manually end the applications that are using your GPU whenever you want to detach your keyboard.
Can’t open Task Manager? Take a look at this step-by-step guide and fix the issue in no time.
6. Charge your Surface Book
According to Microsoft, you might be unable to detach Surface Book from keyboard simply because your battery isn’t charged.
In order to detach the keyboard, your device must be charged more than 10 percent. After charging your device, you should be able to detach the keyboard without any problems.
7. Wait for 10 seconds before pressing the detach key
If you can’t detach your keyboard, you might want to wait for a couple of moments and then try again. According to users, simply press Detach key for a one second and try to detach the keyboard.
If that doesn’t work, you might have to wait for 10 seconds or more and try again.
That’s about it, once again these are not official solutions, as we picked them up from users of Microsoft Community.
