    Can't adjust screen brightness after Windows 8.1 downloaded

    Chip64

      I have a Lenovo Ideapad P500 Touch.  It has the Intel Graphics 4000 w/ driver version 10.18.10.3621 which says is the latest driver.  All worked fine when I had Windows 8.0.   Once 8.1 downloaded, I cannot adjust the brightness at all.  It indicates that the brightest setting is chosen but the screen is too dark and will not adjust.  Help!
