I believe the accelerometer in this model is intended for "HP 3D Driveguard" to park HDD drive heads to help protect the drive from fall damage. So the sensor was probably not intended to reflect the orientation of the screen.
I looked for a BIOS or firmware update on HPs site but didn't find any that mention the accelerometer or orientation issues. Some searches turn up people using Windows 10 finding the same upside- down orientation problems on this hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767650 Title: Screen rotates upside-down when laptop is not flat To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iio-sensor-proxy/+bug/1767650/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
