Can't adjust screen brightness.
Helllo. I recently updated my Laptop with the latest version of Windows 10. Everything works fine EXCEPT the screen brightness. Earlier I could adjust my screen brightness, but now no matter how much I increase or decrease the level in the control panel, the actual brightness level remains the same, and I think it's at the highest level, since the battery is going done by a scary 10% in 20 minutes. I am currently working on my laptop wearing sunglasses. Please Helpp ! P.S My laptop has got two Display Adapters, Radeon Graphics and Intel Graphics, and I've tried updating both the drivers, and it says that you've already got the best drivers for your device, after searching on the internet.
