Abstract
A system and method to reduce power consumption in a portable computer system while allowing the CDROM drive to continue playing audio CDs. When the system enters a suspend mode, the status of the CDROM drive is checked, and if it is playing an audio CD, it remains powered, otherwise power to the CDROM drive is also suspended. The system recognizes when the audio CD is finished playing and then places the CDROM drive into the suspend mode.
