The Surface Book is a 2-in-1 PC designed and produced by Microsoft, part of the company's Surface line of personal computing devices. Surface Book is distinguished from other Surface devices primarily by its full-sized, detachable keyboard, which uses a dynamic fulcrum hinge that expands when it is opened. The keyboard contains a second battery, a number of ports and an optional discrete graphics card used when the screen part, also dubbed as the clipboard by Microsoft, is docked to it. Unlike Surface Pro devices, which are marketed as tablets, the Surface Book is marketed as a laptop, Microsoft's first device marketed as such. Unlike the Surface Laptop devices, the two parts are detachable.
