Hi, My Brightness settings (Fn+f5/f6) was working perfectly but overnight it suddenly stopped. If I change my brightness manually by going into settings, it works perfectly but I prefer the hotkey way. Individually the Fn, f6 and f5 work perfectly but Fn+f6/f5 isn't working, Fn+f8/f9 (The volume) also works perfectly and it's just the brightness. I tried many methods such as going to the driver page and manually installing the hotkey support, but that doesn't seem to do anything, I even tried to manually install the graphics driver from the driver page, but it only gives me the "Your device isn't supported" Notification,  Incase I checked if I had the correct product selected and it still gave me the "Your device isn't supported" notification so manually installing a graphic driver also didn't work. Please help
