HP ProBook 450 G5 Brightness Keys not Working

HP Recommended
HP ProBook 450 G5 3BZ62EA#ABU
Microsoft Windows 10 (64-bit)

Since a rebuild was done on my laptop the brightness function keys/hotkeys don't work.  Other hotkeys such as volume, mute and flight mode work.


It seems that I need a softpaq, SP88033 to reslove this.


This can be downloaded at;


However the link doesn't work.


Is there an alternative location or mirror site to download this?

That file has been superseded by this one...


The HP HotKey Support (HPHKS) software provides the support for handling the Hotkeys and bezel or cap-sense buttons (fixed notebook buttons that provide quick access to a particular function when pressed) for HP business notebooks. This package is provided for supported computer models that are running a supported operating system.


Fix and enhancements:

- Provides the updated Hotkey Support.     Apr 23, 2020
