Problems solved by technology

[0002] At present, when the main power supply unit (PSU1) and the slave power supply unit (PSU2) in the electronic equipment supply power to the power supply ports of the electronic equipment (such as the mainboard power supply port and the CPU power supply port), if the PSU2 is hot-swapped, it will cause PSU1 Short circuit with the output of PSU2, so that PSU1 can charge the power-down holding capacitor of PUS2, which will cause the output voltage of PSU1 to drop down, causing problems such as shutdown, restart or blue screen of electronic equipment

Abstract

The invention discloses an information processing method and an electronic device. The electronic device is provided with a first power supply unit and a second power supply unit. When the first power supply unit is used as a main power supply unit of the electronic device, and the second power supply unit is used as a slave power supply unit of the electronic device, the method comprises: detecting a first signal, the first signal representing output voltage information of the second power supply unit; based on the first signal, analyzing the power supply connection state between the second power supply unit and the power supply port of the electronic device; based on the obtained analysis result, controlling the second power supply unit to enter an electric power output state, so as to make the output voltage of the first power supply unit stable. Through the method and the device, the second power supply unit can be controlled to enter the electric power output state in time, so as to stabilize output voltage of the first power supply unit, and ensure stable operation of the electronic device.

Description

technical field [0001] The invention relates to electronic equipment power supply technology, in particular to an information processing method and electronic equipment. Background technique [0002] At present, when the main power supply unit (PSU1) and the slave power supply unit (PSU2) in the electronic equipment supply power to the power supply ports of the electronic equipment (such as the mainboard power supply port and the CPU power supply port), if the PSU2 is hot-swapped, it will cause PSU1 Short circuit with the output of PSU2, so that PSU1 charges the power-down holding capacitor of PUS2, which causes the output voltage of PSU1 to drop, causing shutdown, restart or blue screen problems of electronic equipment. Contents of the invention [0003] Embodiments of the present invention provide an information processing method and an electronic device, which can ensure a stable voltage output by a main power supply unit in the electronic device and enable the electron...
