Abstract

A power supplier of a computer system and a power supply method thereof are described. The power supply method includes the following steps, receiving a validation code when a computer system enters a working mode from a standby mode; determining whether the validation code is in accordance with a preset code; If the validation code is in accordance with the preset code, executing a power sequence control so that the power supplier generates a plurality of working voltages required by the computer system; and if the validation code is not in accordance with the preset code, powering off the computer system or keeping the computer system in the standby mode.

Claims

1. A power supply method of a power supplier, comprising:

receiving a validation code when a computer system enters a working mode from a standby mode;

determining whether the validation code is in accordance with a preset code;

if the validation code is in accordance with the preset code, executing a power sequence control, so that the power supplier generates a plurality of working voltages required by the computer system; and

if the validation code is not in accordance with the preset code, powering off the computer system or keeping the computer system in the standby mode.

2. The power supply method according to claim 1, wherein before the step of the computer system entering the wording mode from the standby mode, the method further comprises:

detecting a power-on request signal or a wake-up signal, so as to determine whether the computer system enters the working mode from the standby mode.

3. The power supply method according to claim 1, wherein before the step of powering off the computer system or keeping the computer system in the standby mode, the method further comprises:

if the validation code is not in accordance with the preset code, generating an error signal and performing an accumulation on the occurrence times of the error signal;

determining whether an accumulated occurrence times of the error signal exceeds a preset value;

if the accumulated occurrence times of the error signal exceeds the preset value, powering off the computer system or keeping the computer system in the standby mode; and

if the accumulated occurrence times of the error signal does not exceed the preset value, returning to the step of receiving the validation code.

4. The power supply method according to claim 1, wherein the preset code is generated by a dip switch or a keyboard.

5. The power supply method according to claim 4, wherein the preset code is stored in a non-volatile memory.

6. A power supplier of a computer system, comprising:

a power supply module for providing a plurality of standby voltages and a plurality of working voltages; and

a control module coupled to the power supply module for receiving a validation code and a preset code, based on which to determine whether to control the power supply module to execute a power sequence control according to the validation code and the preset code to convert the standby voltages to the working voltages,

wherein when the computer system enters a working mode from a standby mode and the control module determines that the validation code is in accordance with the preset code, the control module controls the power supply module to execute the power sequence control, so that the power supply module provides the working voltages to the computer system, and when the computer system enters the working mode from the standby mode and the control module determines that the validation code is not in accordance with the preset code, the control module controls the power supply mode not to provide the working voltages to the computer system or to continue providing the standby voltages to the computer system.

7. The power supplier of the computer system according to claim 6, wherein the control module further detects a power-on request signal or a wake-up signal to determine whether the computer system enters the working mode from the standby mode.

8. The power supplier of the computer system according to claim 6, wherein when the validation code is not in accordance with the preset code, the control module generates an error signal and performs an accumulation on the occurrence times of the error signal, the control module determines whether an accumulated occurrence times of the error signal exceeds a preset value, if the accumulated occurrence times of the error signal exceeds the preset value, the control module controls the power supply module not to provide the working voltages to the computer system or to continue providing the standby voltages to the computer system, and if the accumulated occurrence times of the error signal does not exceed the preset value, the control module compares the validation code and the preset code again until the accumulated occurrence times of the error signal exceeds the preset value.

9. The power supplier of the computer system according to claim 6, wherein the computer system comprises an input module coupled to the control module for generating the validation code.

10. The power supplier of the computer system according to claim 9, wherein the computer system comprises a non-volatile memory coupled between the control module and the input module for storing the preset code.
