Brightness Fn buttons not working - driver issue mybe

HP Recommended
EliteBook 850 G4
Microsoft Windows 10 (64-bit)

Hello,

 

my laptop had to be fully restored by my company due to an issue we weren't able to address for the resolution.

The operating system was loaded again and among few issues I am having after a fresh install, I see the Fn brightness function don't work (I mean the ones corresponding to keys F5 and F6) so I can't adjust the brightness using those two keys.

 

Other buttons (e.g. for the sound volume) are working correctly.

Can somebody help me to understand if some driver is missing please?
