Abstract

Abstract An information processing apparatus includes a cover member of a display unit movable between open and closed positions relative to a main body of the apparatus, and a detector for detecting the open or closed position of the display unit so that predetermined information processing is carried out in response to the detection. In another embodiment an information processing apparatus has a disk drive, a display movable between an open position and a closed position, a detector for detecting the open and closed positions of the display, and a controller for switching a drive control mode of a disk drive motor of the disk drive in accordance with the detection output of the detector. In another embodiment, an information processing apparatus includes a cover accommodating a display therein, movable between open and closed positions for displaying input data on the display unit, a memory for storing input data, an external memory for saving data, a detector in the cover for detecting the open and closed positions of the cover, and a controller for saving the data stored in the memory in the external memory when the closed position of the cover is detected by the detector.
