Brightness hot keys not working on ProBook 650 G2

ProBook 650 G2
Microsoft Windows 7 (64-bit)

I have reinstalled windows 7 64 bit and all relevant softpaqs but still can't get brightness hot keys to work all other hot keys work.  I have tried older versions of the  hot software and older versions of intel graphics driver. Any help would be appreciated.

 

Thanks

 

Matt

 Fixes an issue where the microphone mute and screen brightness buttons do not function properly when Device Manager is running.

Thank you for your response

 

Unfortunately, I had tried that earlier.  You are correct in that the mic mute isn't working either but it's all the time not just when device manager is open.

 

I appreciate your help
