Embodiment Construction

[0026] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0027] Please refer to figure 1 As shown, it is a block diagram of some components of the computer system of the present invention. In this embodiment, it is assumed that the computer system 100 is in a standby mode (Standby Mode, such as an idle mode (Idle Mode) or a power-off mode). The computer system 100 includes a power supply 110 , and the power supply 110 includes a power supply module 120 and a control module 130 . The power supply module 120 is used for providing multiple standby voltages and multiple working voltages. Wherein, the standby voltage is the voltage required by the computer system 100 in the standby mode, and the working voltage is the voltage required by the computer system 100 in normal operation. Also, the standby voltages include 1.1V, 1.25V, 1.5V, 3.3V, etc., and the operating voltages include 1.1...

Abstract

The invention discloses a power supply of a computer system and a power supply method of the computer system. The power supply method comprises the following steps: when the computer system enters a work pattern from a standby mode, receiving a verification code, judging whether the verification code is consistent to a preset code, if the verification code is consistent to the preset code, carrying out power supply sequence control to enable the power supply to generate a great amount of work voltage the computer system needs, and if the verification code is not consistent to the preset code, powering off the computer system or keeping the computer system in the standby mode.

Description

technical field [0001] The invention relates to a power supply, in particular to a computer system power supply and a power supply method thereof. Background technique [0002] Generally speaking, the power supply usually divides the voltage supply into auxiliary power (AUX Power) and main power (MAIN Power). The standby power is the standby power used by the computer system in the standby mode, and the main power is the main voltage source actually required for the computer system to operate. By separating the two voltages, when the computer system is in the standby mode, unnecessary power consumption can be avoided to cause waste of wasted power. [0003] When the standby power is activated, the computer system enters the standby state. Next, when the computer system detects a boot request or a re-login request (commonly referred to as S0-S5 boot modes), through the power supply sequence and judgment management system inside the computer system, the modulation voltage ci...
