Power supply control method for standby power supply and power supply, motherboard and computer thereof

Abstract

The invention discloses a power supply control method for a standby power supply and a power supply, a motherboard and a computer thereof. The method comprises the following steps: detecting the voltage of a first pin of a power supply connector of the computer; when the power supply connector is not connected to a motherboard connector of the computer, measuring the voltage of the first pin as afirst voltage value, and cutting off an output standby voltage; when the power supply connector is connected to the motherboard connector, measuring the voltage of the first pin transformed from the first voltage value to a second voltage value different from the first voltage value, and outputting the standby voltage; and when the power supply connector is separated from the connection with the motherboard connector, measuring the voltage of the first pin retransformed to the first voltage value, and cutting off the output standby voltage. The power supply control method and the power supply,the motherboard and the computer which use the method to control the power supply of the standby power supply can solve the problem of poor or false operation of the motherboard caused by inserting the power supply connector into the motherboard with charge.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a power supply control method of a computer standby power supply and a power supply, a mainboard and a computer using the method to control the output of the standby power supply. Background technique [0002] As we all know, in the field of electronic equipment, for electronic equipment such as televisions and computers, maintaining a stable operating voltage and operating current is an important condition for maintaining the normal operation of the equipment. [0003] However, during the assembly process of desktop computers, the staff or users who assemble the computer may often inadvertently insert the connector of the computer power supply directly into the connector of the motherboard when the computer system or the end user's AC power is still connected. At this time, due to the output of the 5V Standby (standby) voltage of the computer power supply, the voltage or curre...

AI Technical Summary

Problems solved by technology

[0004] An object of the technical solution of the present invention is to provide a power supply control method for a computer standby power supply and a power supply, a mainboard, and a computer that use the method to control the output of the standby power supply, and can control the cut-off or connection of the standby power supply. When the main board is connected, the standby power supply is disconnected. When the power connector is connected to the main board, the standby power supply will be turned on and output voltage, thus solving the problem of plugging the power connector into the main board with power and causing the main board to malfunction or malfunction.
