Abstract

A low power media player is provided for an electronic device, such as a hand-held portable computer having capability to operate an application during a low power mode. During the low power mode, portions of hardware, software, services, and/or other components of the portable computer that are not necessary to the operation of the low power media player are suspended or otherwise deactivated. Rather than repeatedly accessing a hard disk to read media files for playback, the low power media player limits its number of access operations by reading as many media files as possible during each access operation, and then caching the read media files. When playback of the media files is to be performed, the media files are read from the cache, thereby reducing the amount of power consumption attributable to hard disk access operations.
