ABSTRACT:
A portable computer provided with a power switch, a drive for an optical device, an audio signal processing unit processing the audio data of a disk inserted into the optical device drive, and an inputting unit formed with a plurality of selection buttons for inputting movement and selection of a pointing cursor. Each selection button of the inputting unit has a selection inputting function in response to a plurality of operations of the optical device drive. The audio signal processing unit is supplied with assistant power while system power is turned off. The audio signal processing unit controls the optical device drive based on selection by the selection button as inputted. With this configuration, the present invention provides a portable computer wherein an inputting unit, for movement and selection of the pointing cursor when the optical device drive is operated while the power switch is turned off, can be utilized as a control button involved in reproduction of the optical device drive.
