Comment 12 for bug 1767650

This affects HP/Compaq 8510p too. This model too was sold with "3D DriveGuard", and the screen orientation is:

flat: nothing changes, keeps whatever is already in use

lift the laptop tilt slightly up (screen-mount is higher than mouse-pad: up-side down !! This is very annoying

Keyboard all the way up, like a painting, normal orientation: up side down !!

Keyboard all the way up, like a painting, upside down: screen turns the normal way. This is how you recover the screen orientation

Put laptop on the sides, screens turns as expected
