<p>PROBLEM TO BE SOLVED: To supply electric power from a battery for a longer time. SOLUTION: When a dedicated key 71 is operated in suspend mode, a switch monitor circuit 6 detects that and initiates an interruption to a CPU 61. At this time, the CPU 61 supplies necessary electric power to a CD-ROM controller 67, a CD-ROM drive 6, and an audio circuit 68 needed for CD reproduction. Consequently, a CD can be reproduced still in suspend mode.</p> |
