    Brightness Control isn't working with Win10 + Intel Video Driver 10.XXX

      Since I upgraded last year my Lenovo ideapad z500 from Win 8.1 to Win 10 I experience an error with the brightness control function.

       

      The error occurs in combination with:

      - Lenovo z500 notebook

      - Intel HD Graphics 4000 Chip

      - Win 10

      - and the Intel Video Driver 10.18.10.3277!

      When I change the brightness setting in one direction it switches to lowest level and stucks there. No way to change the brightness back -> working nearly impossible.

       

      The only way to get back the brightness function, is to downgrade the Intel Video Driver to version 9.17.10.3223.

       

      Since the problem is know for a while, I'd like to know if there is any effort from intel to fix that issue.
