How can I ensure my Samsung Series 7 is actually using the Radeon switchable graphics?
Solution 1:
The mobility checker on AMD's website will download the generic drivers if your system passes. Once you have the CCC, you should be able to check the GPU switching. The 7 series also has had multiple BIOS updates for the issue, and while it's not 100% fixed, the new BIOS at least lets you force it to use only either the IGP or the AMD.
The direct download for the current mobility drivers is http://www2.ati.com/drivers/mobile/12-4_mobility_vista_win7_64_dd_ccc.exe, and a few other websites also host it with mods to work on unsupported systems.
