Abstract

A power management device and a power management method, used in a computer system with audio output, the power management device includes a battery unit; a power detection unit is coupled to the battery unit for detecting the power of the battery unit; a memory unit stores a music file, the music file has sound data and sound output parameters; a central processing unit is coupled to the power detection unit and the memory unit, and retrieves the music file and outputs a sound signal; and An audio output unit is coupled to the central processing unit, and the audio output unit receives the sound signal and generates a music signal. Wherein, the central processing unit reduces the sound output parameter in the music file as the power of the battery unit decreases.

Description

technical field [0001] A power management device and a power management method, especially a power management device and a power management method used in a computer system with audio output. Background technique [0002] Generally, portable computer systems (portable computer systems) use batteries as their power supply. Due to the increasing functions of portable computer systems, the demand for power supplies is also relatively high. Without affecting the normal operation of the computer, the power supply Management is very important for portable computer systems. [0003] Referring to FIG. 1 , it is a schematic diagram of a known portable computer system architecture. The traditional portable computer system 1 has a central processing unit 12 (CPU), a hard disk 13 (Hard Drive), an audio board 14 (AudioBoard), a power supply 15 (Power Supply) and a power management circuit 17 ( PMIC), and the portable computer system 1 is further coupled with a display unit 2 (Monitor) ...
