The invention relates to the technical field of electronic equipment, and in particular to a coreless notebook computer and a notebook computer.

A conventional notebook computer consists of a core part (CPU, graphics card, wireless and wired data network connection devices and peripheral devices that assist the CPU and graphics card work) and auxiliary parts (battery, display screen and peripheral interfaces). With the continuous improvement of the performance and functions of smart phone chips and solutions, a smart phone can completely replace the core part of a conventional notebook computer. Not only that, but smartphones also include features such as voice communications and wireless data networks missing from laptops.
