Abstract

The invention relates to a power-saving power supply management unit, a computer system and a power saving method of the computer system. In one embodiment, the computer system comprises the power supply management unit for managing the power supply of the computer system, a storage unit for recording image data and a graphic processing module. The graphic processing module reads the image data recorded in the storage unit according to a storage clock and performs the graphic processing of the read image data so as to output the image data to a display unit to display the image data in form of a picture that can be seen by users; and the power supply management unit gates the storage clock when detecting that the graphic processing module does not need storing the storage unit for processing and outputting the image data. Thus, the method can reduce power for clock signal conversion to save the power of the computer system.

Description

technical field [0001] The invention relates to a power management unit capable of saving power, a computer system and a power saving method thereof, in particular to a computer system capable of reducing power consumption when a display unit of the computer system is idle and a power saving method thereof. Background technique [0002] Power control and reducing power consumption have always been an important issue in the development of computer systems, especially in the case of limited power supply for portable computer devices. In order to achieve the effect of power saving, currently well-known computer system power saving methods include advanced configuration and power interface (Advanced Configuration and Power Interface, ACPI) to detect the use of the computer system, and according to the defined power state (Power state), when the computer system is in different degrees of idle state, the power supply of some hardware devices is turned off, so as to reduce the over...
