Lenovo Z400 touch Brightness Problem in Windows 10

I have just upgraded my laptop to Windows 10 and when I booted it up the brightness on my screen was very dim. I tried to adjust the brightess as I normally would (Fn + F11 (or F12)) but it doesn't change the brightness even though it recongnizes me wanted to change it. 

 

I had this problem when upgraded to Windows 8.1, but the fix I had for that doesn't work on Windows 10. Any help?

Hi,

 

I have the same issue with my z 500 touch. The problem was fixed with an intel driver's update for win 8.1.

 

I hope we can get an update for windows 10.

I solved the issue by installing intel hd driver for win 8.1.

Once you extracted the files you have to go to the folder : C:\drivers\Intel Video Driver and you have to choose the driver version that you want to install. Then right click to setup, properties, compatibility and run in compatibility mode for windows 8. then execute setup. That should work.

I fixed it installing the Realtek PC Camera drivers available on the lenovo's drivers page (for Z400)
