<p>PROBLEM TO BE SOLVED: To supply power from a battery for a longer period. SOLUTION: When a dedicated key 71 is operated in the state where a suspension mode is set, which is detected in a switch monitoring circuit 66, a CPU 61 is interrupted. At the time, the CPU 61 supplies power required for CD reproduction to a CD-ROM controller 67, a CD-ROM drive 5 and an audio circuit 68. Thus, a CD is reproduced while the state of a suspend mode is maintained.</p> |
