Abstract

The invention relates to a computer system and a dynamic power saving method thereof. The computer system comprises a switch, a system power supply unit, and an arithmetic control unit. The switch is selectively and electrically connected with a peripheral device. The system power supply unit is electrically connected to the switch. The arithmetic control unit is electrically connected to the switch, detects whether an application program being related to a peripheral device is implemented, and outputs a switch control signal to the switch so as to decide whether the power supply unit supplies working power supply to the peripheral elements.

Description

technical field [0001] The present invention relates to a computer system, and in particular to a computer system and a dynamic power saving method thereof. Background technique [0002] Please refer to FIG. 1 , which is a schematic diagram of a traditional computer system and a USB device. The traditional computer system 10 includes a central processing unit 162, a chipset 166, and a system power supply unit 164, and the chipset 166 includes a north bridge 1662 and a south bridge 1664, wherein the south bridge 1664 has a universal serial bus host controller (Universal Serial Bus Host). Controller) and PCI-E controller. [0003] The central processing unit 162 communicates with the south bridge 1664 via the north bridge 1662, and the south bridge 1664 can control the operation of the peripheral components 20 through the control signal line 1666, wherein the peripheral components 20 can include USB devices or PCI-E devices. The system power supply unit 164 can provide a wor...
