My friend installed a driver update here in my laptop and after that I got a problem with the brightness of my screen, it's all really dim. I uninstalled the driver update then my built in graphics card (Intel Graphics HD 4000) can't be detected anymore and my AMD Radeon HD 8750M isn't working too. My screen is still dim. What should I do?

the great randini
most laptops have a function key to increase brightness fn +f5
also check power settings, there is a setting in there for brightness.
if it is a older laptop the backlight may be dying.
