Under Windows 10 everything works perfectly. I'm just an individual who means nothing to them. I bought their product which they claim fully support linux (whatever this means). Honestly, I thought that Ubuntu Team has capabilities to contact vendors like HP and ask for solutions/help? :( -- Yo

Hi @kai.heng.feng No problem. I tested "event04", logs below: $ sudo evtest No device specified, trying to scan all of /dev/input/event* Available devices: /dev/input/event0: Sleep Button /dev/input/event1: Lid Switch /dev/input/event2: Power Button /dev/input/event3: Power B

Additionally I tested "event16", but there was no reaction (doesn't matter if using Fn + key combinations or when using Fn lock): $ sudo evtest No device specified, trying to scan all of /dev/input/event* Available devices: /dev/input/event0: Sleep Button /dev/input/event1: Lid Switch
