I've got a HP EliteBook x360 (2017), and had an issue with the screen not auto rotating.

I've tried everything I could think of, to get this working. Reinstall Windows, updating drivers and etc. Finally I found out that the Intel management engine / Remote assistance was disabled in "BIOS". After I enabled this feature, the computer installed 3 sensors, and screen rotation started working. :)

Other than that, I love this laptop.
