Notebook computer system with a separable trackball

摘要

A notebook computer system with an easily separable trackball to give the system flexibility. The system makes use of a separable keyboard to achieve the goal of installing and separating the trackball. To this end the notebook computer comprises a keyboard that is able to be at least partially separated from the system, a socket for installation of the trackball module, with the trackball module being partially captured under the keyboard when installed in the socket. A notebook computer having a socket for accommodating a trackball may alternatively be provided with a plain plate, which allows the notebook computer to work normally without the trackball.
