<p>The present invention relates to a portable information apparatus which can maintain electrical power for a longer period of time. Under the condition that a suspending mode is set, when an exclusive key is manipulated, a switch monitoring circuit detects this condition and issues an interruption signal to the CPU. In this timing, the CPU supplies the necessary electrical power to a CD-ROM controller, CD-ROM drive and audio circuit which are required for reproduction of CD. Thereby, information stored on a CD can be reproduced under the suspending mode.</p> |
