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.

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