same issue for me
It's because you have 2 videocards in your laptop, discrete(Ati or Nvidia) and integrated(intel HD)
Nvidia videocard consumes more power of your laptops battery than Intel HD, so when you run something that needs good videocard, your laptop will switch them automatically.
I think blizz will fix that later for our laptops
If you want to run D3 now, you need to make your discrete videocard to be "used always"
