Abstract
A computer system incorporating capabilities for displaying the audio disk track number when the computer system is playing an audio disk. The computer system determines if a disk is present in the disk drive. If a disk is present, the computer system determines if an audio disk is present in the disk drive. If so, the computer system then monitors the disk drive. When the audio disk is played by the disk drive, the computer system displays the audio disk track number. The computer system then periodically polls the disk drive to update the audio disk track number. The computer system displays a battery gauge status when the audio disk track number is not being displayed. The status display is visible when the portable computer is in either an open or closed state.
