Hi,

I am using  HP pavilion g6-2016tx model laptop. Recently, when I turned on my laptop, I found the brighness set to the maximum level automatically. I tried to reduce it using the function key. When I press the function key, it is being displayed that the brighness is reducing but it is not reducing at all. Plese tell me what should I do ?

My laptop has AMD Radeon HD 7600M series graphics card.

Thank you for the reply.

In Solution# 1, you have described how to uninstall the display adapter driver. But you have not mentioned how to re-install it. So, please tell me how to do that. Moreover, when I expanded Display Adapter, I could see two adapters viz. AMD Radeon HD 7600 Series and Intel(R) Graphics HD 4000. So, which one should I uninstall ?

Thanks for replying. Please uninstall both the adapters. Once you restart the computer, the drivers will get automatically installed. 

Keep me posted.
