Abstract:
1. A computer system capable of power management in a working state, the computer system comprising: a processor, operated at a processor frequency; a memory, supplied by a memory voltage and operated at a memory frequency; and a chipset coupled between the processor and the memory, supplied by a chipset voltage; wherein the computer system is provided a plurality of power saving modes under the working state, the chipset monitors data volume of a buffer of the computer system to determine whether to switch the computer system into one of the power saving modes; wherein each one of the power saving modes has individual values of the processor frequency, the memory frequency, the memory voltage and the chipset voltage; while the computer system is switched into one of the power saving modes, the chipset correspondingly changes values of the processor frequency, the memory frequency, the memory voltage and the chipset voltage.
