HP Recommended
Product: ProBook 450 G6
Operating System: Linux

The issue is that under Linux, the brightness keys (Fn+F3 and Fn+F4) do not work.
To be more specific: they work, but they do the same thing Fn+F8 is doing.

Cause: both of these key combinations return the same keycode as Fn+F8 (Mic mute) and as a result they also do the same thing.

Apparently, the issue is not isolated to this particular model and is already known for HP as can be read here:

Solved: Brightness-Keys not working properly - Zbook Studio G5 on Ub... - HP Support Community - 716...

Bug #1841039 “Multiple keys have same keycode on HP ProBook 450 ...” : Bugs : Ubuntu (launchpad.net)
