brightness hotkeys not working since last Windows 10 update

[cerise09]

Since the latest Windows 10 update, the brightness hotkeys are no longer working. The volume hotkeys do still work. I have checked HP Support for hotkey drivers and the only available one is several years old and I think it's the one I already had installed. I noticed that somebody had a similar query for a different notebook PC and the solution suggested was to delete the HP hotkey driver and install a driver from a link suggested by the answerer. While this, apparently worked for them, I am concerned that it is risky and, anyhow, it was a solution suggested for a different model of notebook.

There are also a couple of other solutions posted to different notebook PCs, however all those questions and solutions are a few years old and I have only just encountered the problem with the April 2020  update.

(Hotkey driver problems following windows updates do seem to be a recurring problem taised in the Community, so perhaps HP should be offering help even for aging PCs.)

I'd be grateful for any suggestions.

Hi:

The only suggestion I can offer would be to try reinstalling the hotkey support driver on your notebook's support page.

Sometimes that works.

HP isn't going to be releasing any newer drivers for that model.

I looked to see if there were any newer releases of the 5.X.XX.X driver version and there aren't any.

The support matrix for the various builds of W10 is below...

Other than that, you would have to experiment with the oldest version 6 driver I could find, but that is for a notebook that is two model generations newer than yours...I have no idea what the results will be.
