The method for detecting the fault of the electronic equipment provided by the embodiment of the invention is suitable for the application scene shown in fig. 1, wherein the application scene comprises an embedded controller EC and at least one power supply, the power supply is connected with the embedded controller, the embedded controller and the power supply are both arranged on the electronic equipment, and the electronic equipment can be a notebook computer, for example. Fig. 1 exemplarily shows an embedded controller 10, a power supply 20, a power supply 21, a power supply 22, and a power supply 23, and the embedded controller 10 is connected to the power supply 20, the power supply 21, the power supply 22, and the power supply 23, respectively.
The embedded controller is used for sending an enabling signal to at least one power supply, then the embedded controller waits for a related power supply PG signal, namely the embedded controller judges whether the PG signal of the power supply is detected, if the embedded controller does not detect the PG signal of the related power supply, the power supply is considered to be abnormal, namely the power supply is an abnormal power supply. And then the embedded controller records the state of the abnormal power supply and numbers the abnormal power supply, and finally outputs the number and the power supply name of the abnormal power supply through a serial port, so that after-sale maintenance can be facilitated.
It should be noted that the method for detecting a failure of an electronic device provided by the embodiment of the present invention may be further extended to other suitable application environments, and is not limited to the application scenario shown in fig. 1.

In the embodiment of the present invention, the enable signal may be understood as a control signal, and the enable signal is used to control the output voltage of the power supply, for example, when the embedded controller sends a 3.3V enable signal to at least one power supply, and the power supply outputs a 3.3V voltage when the enable signal is at a high level.
And 204, judging whether a PG signal of the power supply is detected or not, and if the PG signal of the power supply is not detected, determining that the power supply is an abnormal power supply.
In the embodiment of the present invention, the PG signal is a POWER GOOD signal in the POWER supply, and the PG signal is controlled by the POWER supply and represents whether the POWER supply is ready or not. And after the embedded controller sends an enabling signal to the power supply, waiting for the PG signal of the related power supply, and if the PG signal of the power supply is not waited, considering that the power supply is abnormal. Specifically, after the embedded controller sends an enable signal to at least one power supply, the embedded controller determines whether a PG signal of the power supply is detected, and if the PG signal of the power supply is not detected, the power supply is determined to be an abnormal power supply.

In the embodiment of the invention, the preset time length is used for waiting for the PG signal, and the preset time length can be set according to the actual situation. Specifically, the embedded controller sends an enable signal to at least one power supply, then the embedded controller waits for a preset time period, and if the PG signal of the power supply does not exist within the preset time period, the power supply is considered to be abnormal. Specifically, the embedded controller sends an enable signal to at least one power supply, and then determines whether a PG signal of the power supply is detected within a preset time period, and if the PG signal of the power supply is not detected within the preset time period, the power supply is an abnormal power supply.
Illustratively, the preset time duration is 500ms, the embedded controller sends an enable signal of 5V S0 to at least one power supply, the power supply performs a power-on operation after receiving the enable signal, at this time, the embedded controller waits for 500ms, and waits for a PG signal of 5V S0, that is, the embedded controller determines whether a PG signal of the power supply is detected within 500ms, and if the PG signal of the power supply is not detected within 500ms, meaning that the PG signal is not detected, the power supply is considered to be abnormal.
And step 206, recording the state of the abnormal power supply and numbering the abnormal power supply.
After the embedded controller determines an abnormal power supply, after-sale maintenance is facilitated, the state of the abnormal power supply is recorded, and meanwhile the abnormal power supply is numbered, specifically, the abnormal power supply can be numbered according to the power-on sequence of the power supply.
In the embodiment of the invention, the embedded controller sends an enabling signal to at least one power supply, then judges whether a PG signal of the power supply is detected or not, if the PG signal of the power supply is not detected, the power supply is determined to be an abnormal power supply, then the embedded controller records the state of the abnormal power supply and numbers the abnormal power supply, and through the mode, when the power supply is abnormal, the electronic equipment can keep a fault record, so that subsequent maintenance personnel can find the related power supply to perform fault elimination conveniently.

In the embodiment of the invention, after the embedded controller sends the enabling signal to at least one power supply, if the PG signal of the power supply is detected within the preset time period, the power supply is considered as a normal power supply. Taking the above example as a support, the embedded controller sends an enable signal of 5V S0 to at least one power supply, the power supply performs a power-on operation after receiving the enable signal, at this time, the embedded controller waits 500ms, and when the PG signal of 5V S0 is received, that is, the embedded controller determines whether the PG signal of the power supply is detected within 500ms, and if the PG signal of the power supply is detected within 500ms, which means that the PG signal is already detected, the power supply is determined to be a normal power supply.
In some other embodiments, the method further comprises: and outputting the information of the abnormal power supply.
The information of the abnormal power source includes a power source name and a number of the abnormal power source. Specifically, as shown in fig. 3, after the embedded controller records the state of the abnormal power supply and numbers the abnormal power supply, the power name and the corresponding number of the abnormal power supply are output through a serial port, so that after-sale maintenance can be facilitated.
