    • 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.
    • 提供了一种用于电子设备的低功率媒体播放器,例如具有在低功率模式下操作应用的能力的手持便携式计算机。 在低功率模式期间,对于低功率媒体播放器的操作不需要的便携式计算机的硬件,软件,服务和/或其他组件的部分被暂停或以其他方式被去激活。 低功率媒体播放器不是重复访问硬盘来读取媒体文件进行播放,而是在每次访问操作期间通过阅读尽可能多的媒体文件来限制其访问操作数量,然后缓存读取的媒体文件。 当要执行媒体文件的播放时,从缓存中读取媒体文件,从而减少归因于硬盘访问操作的功耗量。
