Definition: Surface Book

A convertible Windows laptop computer from Microsoft. Introduced in 2015, the Surface Book screen detaches like a hybrid tablet. However, the screen can also flip over like a convertible laptop. A more powerful graphics processor (GPU) resides in the keyboard, and when attached, makes the Surface Book more robust for multimedia editing and similar tasks.

Surface Book 2 and 3
The Surface Book 2 debuted in 2017, and the 3 in 2020. However, the Surface Book is no longer available in the Microsoft Store. See Surface versions, discrete graphics, convertible laptop and hybrid laptop.

Hybrid or Convertible
Available in 13.5" and 15" screen sizes, the Book's screen can detach (hybrid) or fold over (convertible). (Images courtesy of Microsoft.)
