I suppose this is a laptop? You will need to go the the machine's web page and download and install drivers for this laptop. Laptop drivers are specific to each brand so you have the FN key functionality.

Screen brightness is almost always lower when you're running of the battery. Unless you're doing video encoding there's really no need to have the 3000 HD active. For ATI it also best to use the a wizard for your brightness and colors because the other sliders are only for when playing video.

You have to set it for 'all channels'
Here's a slightly outdated page on it.

Catalyst Control will only work with a video playing. Or a game running.
How did you used to change brightness?
