When I first got my surface book I could detach it without any issues, however I am no longer able to.
Now when trying to detach it the detach button's light blinks green but nothing happens. When I hover over the software detach option it says "Surface Detach: Detached" and when looking at the battery status it say "Battery 1 not available." Everything appears to indicate it does not think it is currently attached to the keyboard, when in fact it is.
I did confirm the battery is fully charged. Also, I just did a factory reset, again no change in this. With me doing a reset I'm assuming it's some sort of hardware issue.
Any thoughts on this? Is there some sort of service or app I could reset?
I got this issue resolved. To give credit where credit is due I referenced information from the following two pages:
I believe many people previously suggested doing a two button shutdown, but maybe I was doing something incorrectly. Essentially you need to enter the Surface Book Bios, then exit.
Here are the steps I took to resolve the issue:
- Shutdown the Surface Book.
- Hold down the power button just long enough to turn it back on.
- Hold the volume UP button until you enter the bios (this is the left side of the volume control, if you are facing the screen. This is also the side of the volume control closest to the power button).
- You do NOT need to make any changes in the bios.
- Exit the bios, you will be prompted that changes will be saved.
- The computer should restart.
After doing this the behavior for my button completely changed and it gave some errors about needing elevated permissions which wouldn't go away, but I was able to restart it again and before I logged in I was able to detach it completely from the device without any issues.
Normal operations have now been restored and I am able to detach and re-attach it like normal.
EDIT: Something I forgot to include, which olykwik pointed out in another response, is that you may need to reset windows prior to performing this fix. I say "may need to" because I did not test this prior to resetting windows, so I don't know if resetting windows is required or not, but I did reset windows before I did these steps.
I would suggest first attempting this BEFORE resetting windows (as this will cause you to lose all files/applications, depending on your selection), but if it still does not work you might need to reset windows, then follow these steps.
If this resolved your issue, please mark its as the answer/helpful so others can find it more easily.
