My type cover started working on Windows 10 Preview 19013.1122 slow ring.
The type cover suddenly stopped working in October 2018. I tried all the approaches in this forum and from other websites. Nothing worked including battery drain. The auto-rotation was not working either. I always saw its driver was installed successfully and it was connected. However, it was not working.
I installed the windows preview in the late spring 2019. Type cover was not working until recently I tested the cover last week, Suddenly it's back to work in Windows and UEFI. I tested it for rebooting, shutting down and booting, disconnecting and reconnecting, almost all the cases. It's just working perfectly as long time before. I don't know what happened - I didn't do anything else.
Hope my experience could help you who also suffered from this issue. Also so deeply disappointed by Microsoft service and their attitude of ignorance. I will NEVER buy any Microsoft computer in the future! Since Jan. 2019, I've switched to DELL Precision 5530 2-in-1, which is just working!
