Finally I tried the AMD beta 12.11_beta4 ones; these drivers install, but I still dont get control over the switchable graphics panel. I am sure, as someone mentioned earlier, it's because the AMD beta drivers don't match the signature/version of the INTEL ones.
So my problem is... given the above, where do I find a matching AMD / INTEL driver? I saw someone mentioning an HP machine with my same graphics config, would that work or are there potential pitfalls?
I dont really mind if the driver is the latest and greatest, as long as I get back control over switcheable graphics and brightness. Hopefully it will also improve my battery life, it's been cut in half since updating to Win 8, but might be faulty power management settings. Damn lenovo....
thanks in advance, any help would be really precious!
I think you can try SoftPaq 58788, as it does support the 6470M as well. You may also want to run DriverFusion first to remove any existing drivers you have installed.
After that, you can update via the AMD Catalyst 12.10 or 12.11 Beta.
