    Is there any option to disable the GPU so the Surface Book works as if it didn't exist?

    IDK, try disabling it in Device Manager.

    Isn't it a reason you bought the version with dGPU?

    Turning off the dgpu might save battery power and it might generate less heat. Dunno, but maybe.

    That doesn't disable the dGPU, its frame buffer is still in tact and is still drawing power along the PCIe Bus, etc.

    because there is better solutions instead of disabling the dGPU, its like buying a fast car with nice turbo and then asking the dealer to disable the turbo :rolleyes: also battery life and heating issue will sort itself out when win 10 doesn't have so many bugs! just need a couple of more updates and then it will be all good...

    Err, I think the dGPU is by default off. See this video and Anandtech's description:



    It doesn't "disable" the dGPU, but just makes sure it doesn't turn on.

    From all the threads we've seen so far about bugs, I think there are about 100 different reasons why you would want to disable it (besides any power or heat concerns even come into play).
