@rbalint I updated the laptop to Ubuntu 20.04. The mic still does not enable/disable with FN+F8 combo and the light is constantly on. I haven't been able to implement in the following link (due to lack of technical know how): https://wiki.archlinux.org/index.php/HP_EliteBook_840_G1#Enable_the_microphone_muting_key
However, the auto screen rotation issue appears to have been fixed in 20.04 as detailed in the link you posted. https://github.com/systemd/systemd/issues/13463 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848862 Title: HP Elitebook 840 G1 - 19.10 - Microphone mute key does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1848862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
