    can't change screen brightness after updating IntelHD4000


    hello
    i have a very confusing problem with my screen brightness
    i have Lenovo G580 running 8.1 with intel HD4000 and Nvidia Geforce 610 & Intel CoreI5 3210 2.5GHZ 3rd generation
    the problem occurs after few days from updating the Intel video card which is simply i can't change the screen brightness whether using the [function+uparrow ] or control panel
    it works well when i roll back the driver
    so am i stuck with the old driver which i can't update or what?
