    As of now, Windows 8 AMD drivers don't have brightness controls. This seems to be due to incorrect values in the registry.

    If you're running Windows 7, and have a 2G Tm2 (Core i3/i5) could you please check the correct values in the registry? More info here: The Ramblings of Adrynalyne: Fix Brightness Control for Windows 8 AMD SG Drivers

    Please post both the values for 0001 and 0000. Thank you in advance!

    It's simple, just follow these steps (assuming you don't know how to):

    1) Open regedit (write regedit on the start menu search)

    2) Click and open "HKEY_LOCAL_MACHINE" -> "SYSTEM" - "ControlSet001"

    3) With "ControlSet001" highlighted, go to "Edit" - "Locate" and write "FeatureTestControl". Click locate next.

    4) It should take you to a folder called "0000" and to the key "FeatureTestControl". The key should have something like "0x0000f920". What I need is the "f920" part of that number". It might be "f900", "f920"...

    5) Check the same key value in the folder "0001".

    Thanks!

    :D :D :D :D :D :D

    You should have started with "first, ensure your computer is securely plugged to a power source". I know my way through the Registry, I just didn't want to read that dude's whole webpage.... :p Not sure if my specific TM2 model applies to your study. Here's the data I found:

    Edit: I always boot with Intel Graphics. I rarely use the AMD graphics.

    I know you knew :D, I did it so anyone could check it.

    Anyway, it didn't work. Intel GPU brightness is working fine, AMD GPU won't work regardless of the value in the registry.

    I have no idea on how to solve this one... :(

    have you tried a hybrid of the two? 800 for the intel 840 for AMD. I seem to remember him saying that the 0001 was the dedicated card.
