I've have a HP Pavilion dv6 laptop. I had a recent driver update installed for the AMD Radeon HD 7400M series through my Windows 10 update. After the update, I'm not able to adjust the brightness settings in my laptop and I had to rollback the driver update to the previous version - 15.200.1062.1004. But the new driver update gets installed every time when I restart my machine. Does anyone else face the same issue? Any help would be highly appreciated.
