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Here's a slightly outdated page on it.
Adjust Gamma, Brightness, and Contrast on a LCD Monitor

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

That's why I said to go to the manufacturer's support website and download the graphics driver from there, not from AMD. The may have a special utility/driver for the brightness function, a standard driver will not.

Read over these steps to make sure you followed the Best Practices to get a perfect Clean Reinstall - Factory OEM Windows 7. If not I would do it over. Win7 drivers are not handled at all like an XP install as it is the first driver-complete OS with all drivers in the installer or quickly updated via optional Windows Updates. Only after all Updates are done should you import any missing drivers in Device Manager. This development for Win7 now allows no user driver interaction at all in Win8.

The first place you should look for screen brightness is on the Control Panel>Power Options page which has a slider for brightness under Battery and Plugged In power choices.

However some OEM's have special added software in addition to the Display driver to control Function Keys and other functions. So you want to look over carefully the Lenovo Support Downloads webpage for your exact model, under Downloads and specifically also Software. Ask back if you have any questions doing this. Be sure not to install a bunch of other Lenovo crapware as this will defeat the purpose of getting the vastly superior Clean Reinstall.
