PURPOSE: A substructure of a lap-top PC is provided to promote the efficiency of computer functions by semi-permanently increasing the life of a battery of a notebook PC, by providing a convenient mouse, by removing cables unnecessary for computers, and by integrating CPU chips and peripheral elements. CONSTITUTION: The life of a battery of a notebook PC is semi-permanently lengthened by a charging battery case. A joystick mounted on a body of the notebook PC is operated by the long finger. A touch button for the first finger is installed on the left of the joystick. A touch button for the thumb is installed right under the button for the first finger. In case that all circuits of the PC are simply and clearly formed, the speed of the computer is increased. The size and the weight of the PC are reduced through circuit chips. A structure of an auxiliary memory unit is unified through MD diskettes. Therefore, the efficiency of functions of the PC is promoted.
