Surely if you want to do something that needs a GPU then having it switch off beacause your on battery kind of defeats the point of having a laptop.
Now I can see the point of having a chipset that only powers the GPU when its features are being used. If I am logged on and checking my mail then I dont really need my GPU so no need to have it running. However once I have checked my mail and want to game for 20mins or so whilst I'm waiting for my flight then fire up my GPU.

Why would you want to do it this way?
