Hey, you can “open” your laptop computer if we are staying true to the “notebook” analogy. Notebooks can be opened, and you can open your notebook computer, it just doesn’t necessarily mean you turned it on.
Anyway, GPU doesn’t magically make everything go faster. Even if some of your apps or your OS’ graphical interface can be accelerated with GPU, running small tasks on GPU usually is a waste, as any speed up would be traded for data transfers between the GPU and CPU. So unless it’s your browser making use of the GPU as it renders streaming video or HTML5 graphics, you are not going to notice a huge difference unless you are playing games, or rendering videos.
