I think this bug is related to a hardware failure/feature in the hinge mechanism. I could reproduce the auto rotation lock at a certain angle of the hinge.
This still does not explain why I could not change the orientation manually (why the "Orientation" setting in the "Display Settings" Menu showed no dropdown menu)
