    Many people are having the problem - mainly happening on ASUS notebooks with discreet AMD graphics - that drivers newer than Catalyst 13.4 are failing to turn on the notebooks LCD backlight.

    The solution worked for me and many others is the following:

    Start Regedit registry editor and add/change key like this

    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000]
    "KMD_EnableBrightnessInterface2"=dword:00000001

    if the key exists with value 1 already, maybe setting to 0 will help.
    :)

    I have this problem on HP G62-a14ER.
    Thanks for advice, I'll try it ASAP.
