The power supply 23 is connected.

The embedded controller is used to send an enable signal to at least one power supply, and then the embedded controller waits for the relevant power supply PG signal, that is, the embedded controller determines whether to detect the PG signal of the power supply, and if the embedded controller determines whether to detect the PG signal of the power supply. If the controller does not detect the PG signal of the relevant power supply, it is considered that the power supply is abnormal, that is, the power supply is an abnormal power supply. Then the embedded controller records the state of the abnormal power supply and numbers the abnormal power supply, and finally outputs the serial number and the power supply name of the abnormal power supply through the serial port, thereby facilitating after-sales maintenance.

It should be noted that, the electronic device fault detection method 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 an actual application process, the application environment may also include more or less power supplies.

As shown in FIG. 2 , an embodiment of the present invention provides a fault detection method for an electronic device. The method is applied to an electronic device, and the method is executed by an embedded controller inside the electronic device. The method includes:

Step 202, sending an enable signal to at least one power supply.

In this 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, When the enable signal is at a high level, the power supply will output a voltage of 3.3V.

Step 204, determine whether the PG signal of the power supply is detected, and if the PG signal of the power supply is not detected, it is determined that the power supply is an abnormal power supply.

In the embodiment of the present invention, the PG signal is the POWER GOOD signal in the power supply, also known as the "power good" signal, and the PG signal is controlled by the power supply and represents whether the power supply is ready. When the embedded controller sends the enable signal to the power supply, it waits for the PG signal of the relevant power supply. If there is no PG signal waiting for the power supply, it is considered that the power supply is abnormal. Specifically, after the embedded controller sends an enable signal to at least one power supply, the embedded control determines whether the PG signal of the power supply is detected, and if the PG signal of the power supply is not detected, confirms that the The power supply mentioned above is abnormal power supply.

In some of these embodiments, as an implementation of step 204, the method includes: judging whether the PG signal of the power supply is detected within a preset time period, and if the power supply signal is not detected within the preset time period PG signal, then it is determined that the power supply is an abnormal power supply.

In the embodiment of the present invention, the preset duration is used to wait for the PG signal to come up, and the preset duration can be set by itself according to the actual situation. Specifically, firstly, the embedded controller sends an enable signal to at least one power supply, and then the embedded controller waits for a preset time period. If the PG signal of the power supply does not come up within the preset time period, it is considered that the power supply is abnormal . Specifically, the embedded control sends an enable signal to at least one power supply, and then determines whether the 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, It is true that the power supply is an abnormal power supply.

Exemplarily, the preset duration is 500ms, the embedded controller sends a 5V S0 enable signal to at least one power supply, and the power supply will perform a power-on operation after receiving the enable signal. The embedded controller will wait for 500ms until the PG signal of 5V S0 rises, 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 not detected within 500ms , which means that the PG signal is not up, and the power supply is considered abnormal.

Step 206: Record the state of the abnormal power supply and number the abnormal power supply.

After the embedded controller determines the abnormal power supply, it is convenient for after-sales maintenance, records the state of the abnormal power supply, and numbers the abnormal power supply. The abnormal power supply is numbered.

In the embodiment of the present invention, the embedded controller sends an enable signal to at least one power supply, and then determines whether the PG signal of the power supply is detected, and if the PG signal of the power supply is not detected, it is determined that the power supply is abnormal power supply, and then the embedded controller records the status of the abnormal power supply and numbers the abnormal power supply. Through the above method, when the power supply is abnormal, the electronic device will keep the fault record, so as to facilitate subsequent maintenance personnel to find the relevant power supply Troubleshoot.

In some other embodiments, the method further includes: if the PG signal of the power supply is detected within a preset time period, determining that the power supply is a normal power supply.

In this embodiment of the present invention, after the embedded controller sends an enable signal to at least one power supply, if the PG signal of the power supply is detected within a preset time period, the power supply is considered to be a normal power supply. Following the above example, the embedded controller sends a 5V S0 enable signal to at least one power supply. After the power supply receives the enable signal, it will perform a power-on operation. At this time, the embedded controller will wait for 500ms and wait for 5V The PG signal of S0 is up, that is, the embedded controller determines whether the PG signal of the power supply is detected within 500ms. The power supply mentioned above is a normal power supply.

In some other embodiments, the method further includes: outputting the information of the abnormal power supply.

The information of the abnormal power supply includes the power supply name and number of the abnormal power supply. Specifically, as shown in FIG. 3 , after the embedded controller records the state of the abnormal power supply and numbers the abnormal power supply, it outputs the power supply name and the corresponding number of the abnormal power supply through the serial port, thereby Can facilitate after-sales maintenance.
