Abstract

The embodiment of the invention discloses an electronic equipment protection method. The electronic equipment comprises a control switch which controls power supply output. The method comprises the steps that whether an abnormal event occurs is detected; if the abnormal event is detected, a control signal which controls the control switch is generated; and based on the control signal, the control switch is controlled to switch off the output path of the power supply. Correspondingly, the embodiment of the invention further discloses the electronic equipment. According to the invention, effective shutdown is realized after the electronic equipment is abnormal; and the potential safety hazard of continuous power on of an abnormal chip of the electronic equipment is eliminated after the electronic equipment shuts down due to the abnormal event.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a method for protecting electronic equipment and the electronic equipment. Background technique [0002] With the development of electronic technology, the protection requirements for abnormal events in electronic equipment are getting higher and higher. At present, the processing method of electronic equipment for equipment abnormality is as follows: [0003] When the electronic device detects that an abnormal event occurs, it starts a shutdown process, and at the same time notifies a power management module (Power Management, PM) that the chip is powered off. [0004] However, the inventors found in the above technology that when the electronic equipment was shut down due to an abnormal event and the PM chip was powered off, the power supply (for example: external power supply or storage battery) of the electronic equipment was still powered on, so that after the PM chip was powered...
