    Hey all, I've been following all of the guides here, but just can't seem to get my Brightness controls to work in speed mode in windows 7.

    I've tried 169.09, 180.70 and the most recent forceware drivers.

    I've installed the registry file that was recommended in one thread.
    I've tried all kinds of orders. Still, nothing.

    I've currently installed (in this order)
    SPEF
    SonyPI
    Shared Library
    SonyUtils DLL
    Event Service
    The Registry Patch
    NVIDIA Drivers

    They work fine in STAMINA, but not in SPEED. I can't even access them through Windows Mobility Center or Power Options. I can change them a very small amount though the NVIDIA control panel through the "adjust color settings" tab. Otherwise, theres no mobility options in the NVIDIA panel.

    It seems like some people have figured this out. Does anyone have any suggestions? Thanks!

    What about the default drivers Windows 7 finds?

    From what I hear they tend to be the best to use...???

    Nope, the default driver is a Generic VGA. Interestingly, there are no brightness controls for this either :(

    Hmm, this is bad :(
    NVidia drivers won't work?

    It may be that the graphics driver is somehow linked to a Sony utility... but it shouldn't be...

    I also tried some nvidia drivers on windows update that weren't specifically for my laptop. No luck :/
