Brightness hotkeys not working ZBook 15 G4

[hermidalc]

Hi - the brightness hotkeys on my ZBook 15 G4 have not worked since the Windows 10 April 2018 major update.  I have everything fully up-to-date on my ZBook 15 G4, including all HP driver and software updates and all Windows 10 updates.  The problem specifically started right after my computer restarted after that Windows update.

Could you help me fix this?  Unless there is something not on the HP support drivers and software page and not available automatically via HP Support Assistant then I don't know what to do as my laptop is up-to-date regarding these.  I honestly think that Windows changed something and the Hotkeys software needs updating on the HP side?

I have a full HP Care Pack with 5 years support.

Hi:

See if the Hotkey software from the zBook 15 G5 works for you.

It is a newer version and date...

6.2.44.1 Rev.A   May 29, 2018--this was released after W10 v1803 came out.

The Hotkey software on your zBook support page is:

6.2.38.1 Rev.A    Jul 6, 2017

https://ftp.hp.com/pub/softpaq/sp80501-81000/sp80874.exe

Some forum members were able to get the brightness Fn keys to work by simply reinstalling the driver on their notebook's support page.

Thank you, problem fixed.  Your recommendation to install the newer version HP Hotkey Support on the ZBook 15 G5 software and drivers page corrected the issue.
