Function keys F5/F6 won't dim screen since Windows 1803 update

[GeoffMills]

Hi,

The F5/F6 function keys (screen brightness) don't work since the Windows 10 1803 update.

The  F4 (screen select) also does not work but the volume control F8/F9 works OK.

- Applied all HP updates

- Applied all WIndows updates

- Shut downthen restart laptop

- gone into BIOS, saved, restart

The Windows 10 Settings | Display lets me dim the screen OK

Any idea's on how I can fix this, I change the screen brightness every night

Thanks

Geoffrey Mills

HiyA,

I had the same issue with my 840 G4, installing the Hotley Support software from their software/driver site fixed it for me.

Link to drivers etc.:
