Brightness keys are not working

[Sembatinouamane]

Operating System: Microsoft Windows 10 (64-bit)
Dear sir/madam,

The keys for brightness are not working but the other keys(volume,.....)are working fine ,so i have a problem with just the brightness keys. I have an hp laptop probook 450 g5 i7,I just did a clean install of windows 10 three days ago.


Could you please help me fix it?

You are missing a driver because of the clean install - probably this hotkey driver (click). If that doesn't fix your problem, I suggest you review the full list of drivers for your model.

Hi David,

Thanks for your help, I managed to fix the problem, as you said the hotkey software wasn't installed, I installed it and everything works fine now.
Thanks again.

Hi Dimitris
Here's the link to the hotkey software, you should install it and reboot your laptop :

https://support.hp.com/ee-en/drivers/selfservice/swdetails/hp-probook-450-g5-notebook-pc/17047142/sw...

If that didn't work install the Hp support assistant :

The support assistant gives you the option to analyze for missing drivers and install them .

i did try to install the driver and to download the hp support

again, when i try to install the driver

https://support.hp.com/ee-en/drivers/selfservice/swdetails/hp-probook-450-g5-notebook-pc/17047142/sw...

i get the error message that a newer driver is installed and i need to uninstall the newer in order to install this one.

i dont know which is the new driver or how to uninstall it

thanks

I think you need to uninstall the hotkey driver and reinstall it, in my case it wasn't installed after the clean install of windows 10.
