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...
