Since my Surface Book updated a few days ago, I have been having steadily worsening problems. It started with the screen rotation not working. I would have to restart the computer for it to start back working. Then I start having the log-in screen not give me anyway to input my pin number when in tablet mode. Restarting sometimes 2 to 3 times would get me back in. Then the detach button started becoming sluggish to completely unresponsive but the screen would say it was detached even though it had never come off. Today, when I first started my computer the screen was completely upside down. It was attached in the normal laptop position but was upside down. It was for some reason in tablet mode but setting it to laptop mode did nothing to change the orientation. I tried detaching and reattaching the screen but of course this did nothing. I restarted it 5 times before I got the screen orientation to right itself. If anyone else is having these problems and has figured out a way to correct them without pulling out their hair, I would greatly appreciate any assistance. Up until the last few days I was really liking my Surface Book. Thanks
Spent several hours with tech support on 3 different occasions . Did 2 complete resets with fresh installation of Windows 10 both times. In the end had to have device replaced. I must say that my new Surface Book works very well indeed and so far has had none of the issues its predecessor had even after applying all updates. Perhaps I just had A buggy device. If I develop issues with this machine I will update again. Thx for all the replies and solutions.
