I have a Samsung NP700G7C, a gamer laptop, it comes with optimus disabled, even the GPU supports it (GTX675M). It cannot be enabled, computer is unaware of Intel HD4000 inside. As I have seen from a friend with another gamer laptop, he always have problems when launching games, they sometimes want to use Intel HD4000. And it goes on even if you explicitly state that "open this with nvidia gpu". So sad.
