So after an update, I've found that my brightness hotkeys do not work. I have been through this forums before however none of the answers seemed to work. I've updated drivers, reset drivers, and even redownloaded windows. Still nothing. All of my other FN keys work; Volume, Sleep, Project(Windows Key-P), Number Lock, and Scroll Lock. Any help is appreciated.

 

Thanks in Advance Quackers37233

I was in the same boat 10 mins ago. I have checked that I have latest BIOS update. Then I have uninstalled hp hotkey driver and installed latest one from hp drivers site. Didnt work. Then i have uninstalled Intel graphics driver that was installed by windows update. Then I have "DISABLED" FN key support in BIOS (that was the weird move). After boot finished I have finaly had FN support for all but brightness (as you have had). Then I have installed from the same hp drivers site, Intel graphics driver (200+ MB). Finally that gave me FN brightness control. Hope that would help.Cheers.
