AMD notebook drivers:

This will download a "verification tool" which will tell you if your GPU is compatible with the AMD drivers, and download the latest driver.
From AMD:
" ***Important!***
Please note, that the AMD Catalyst Mobility driver package can only be installed on specific AMD Enduro platforms, that are second generation AMD A-series APU, or third generation Intel Core family based.
Please note that all other platforms that do not include support for AMD Enduro Technology are supported through AMD Catalyst Mobility.
The following notebooks are not compatible with this tool:
Notebooks equipped with switchable graphics
Toshiba® notebooks
Sony® VAIO® notebooks
Panasonic® notebooks"
*This means your sytem might not be supported by the "verification tool" above.
In that case use the "AMD Catalyst Mobility" reference drivers. Since it's a reference driver you choose the "AMD Mobility Radeon HD 5000 Series or Newer:" reference driver. And choose your operating system, win 7 64-bit.

*Perhaps this is the same driver that you could download from your laptop manufacturers site? So perhaps for your system, this is the newest driver available. I think graphics companies usually reccomends using the laptop manufacturers drivers.
