    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!

      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


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