I've spent hours looking for a solution to this:
I have an Asus M51Ta laptop with the switchable "" gpu
It came with Vista originally, and I used that for a while, and the switchable functions worked fine. I recently installed Win7 and the switchable functions don't work.
I realize that AMD doesn't support switchable graphics on Win7 at this point ("Available only on Windows Vista® OS.") but I was under the impression that HP and Lenova have some support for switchable graphics on Win7.
Does anyone know of anything for this from asus? or independent developers?
As an alternate solution, does anyone know how to configure the system to just boot with the High-power gpu (presumably in the BIOS)? I don't need to be able to switch cards while the machine is on, just to have the ability to go into "gaming mode" when needed. At the moment the 3650 card is giving me a Code 10, even when I have the other card's drivers completely removed it won't start.
