Computer, computer power supply control device and power supply control method

Abstract

The invention provides a computer, a computer power supply control device and a power supply control method. The device comprises a monitoring unit, a judging unit and a control instruction generating unit, wherein the monitoring unit is used for acquiring state information of one power consumption component in the computer, and the state information of the power consumption component comprises aworking state and an idle state; the judging unit is used for comparing the idle state duration time with a preset threshold time when the state information is in the idle state, and generating a comparison result when the idle state duration time is equal to or greater than the preset threshold time; and the control instruction generating unit is used for generating a control instruction for controlling the power failure of a host power supply according to the comparison result, and the host power supply stops supplying power to the power consumption component based on the control instruction. By using the technique provided by the invention, the power supply of the power consumption component can be thoroughly cut off in the idle state so that the whole computer system can save electricenergy so as to realize timely and flexible power failure according to the state of the power consumption component and improve the power supply efficiency of the system.

Description

technical field [0001] The invention relates to computer power supply technology, in particular to a computer, a computer power supply control device and a power supply control method. Background technique [0002] During the application process of the computer, not all power-consuming components on the computer are in real working state at the same time when the power is turned on, such as digital video disc or digital video disc / compact disc read-only memory (DVD / CD-ROM, Digital Video Disk / Compact Disc read-only memory), floppy drive (FLOPPY) and display, etc., will only really work when the CPU reads and writes data to them, while DVD / CD-ROM and FLOPPY are in an idle state at other times ( IDLE), and the display does not need to display information in some states. Usually, when the computer is in an idle state, there is no control to cut off the power of the above-mentioned power consumption components, that is to say, the power consumption components still consume powe...
