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 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 :

http://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/pl...

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

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.
