Restored Microsoft Surface Book 1 13.5" Intel Core I7 DualCore 8GB RAM 256GB Storage Windows 10

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 Refurbished 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. The Surface Book's design was influenced by a goal to design a 2-in-1 convertible tablet that could be folded like a laptop, and not require the keyboard to be heavier than the tablet portion in order to support and balance the tablet portion. To reach this goal, the Surface development team developed a special hinge on the keyboard that would increase the footprint of the device when opened, thus maintaining the balance without increasing the weight differential between the two parts. The hinge is accompanied by muscle wire locks that secure the tablet portion to the keyboard. The wires are made from nickel titanium—an alloy that contracts when exposed to an electrical current; pressing a release button on the keyboard sends an electrical impulse through the wires that attach or release the clips. The team also worked with the Microsoft team developing Windows 10 to implement a switchable graphics system, where the tablet would be able to switch to a discrete graphics card located within the keyboard when docked, and revert to internal graphics when undocked.
