[0051] The following describes the method, device, equipment, and storage medium for online diagnosis of the status of a laptop computer without disassembly provided by the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0052] Figure 1 The present invention provides a flowchart of a method for online diagnosis of a laptop computer's status without requiring disassembly, as provided in an embodiment of the present invention.

[0053] Combine Figure 1 As shown in the figure, the online diagnosis method for the status of a laptop without disassembling the laptop may include:

[0054] S101, receiving a diagnosis trigger instruction input by a user based on a matrix keyboard;

[0055] S102, the embedded controller controls the GPIO level change based on the diagnostic trigger instruction to select a TTL level debugging serial port path to a standard USB interface;

[0056] S103, receiving the diagnosis trigger instruction input by the user again, and the embedded controller controls the GPIO level change based on the diagnosis trigger instruction received again, so as to select the USB2.0 signal path to the standard USB interface.

[0057] In some embodiments, the diagnosis trigger instruction is determined based on the distance between keys on the matrix keyboard and palm parameters of the human body.

[0058] In some embodiments, when the TTL level debugging serial port path is switched to the standard USB interface, Figure 1 The method may further include:

[0059] The serial port baud rate, data bits and parity bit parameters are configured through the embedded controller, and automatic handshake matching with external diagnostic equipment is achieved through the standard USB interface.

[0060] In some embodiments, Figure 1 The method may further include:

[0061] Detect the current power status of the laptop before switching the signal path;

[0062] If the device is in sleep or shutdown state, the embedded controller temporarily activates the power supply to complete the path switching.

[0063] In some embodiments, after selecting the TTL level debug serial port to pass through the standard USB interface, Figure 1 The method may further include:

[0064] Send hardware self-test instruction set to the laptop through the debug serial port;

[0065] The notebook computer detects the status of the power management unit and the presence status of hot-swappable components based on the hardware self-test instruction set.

[0066] In some embodiments, the hardware self-test instruction set includes embedded controller firmware version verification, mainboard key voltage detection and tolerance range comparison, temperature sensor data reading, and fan speed feedback signal detection.

[0067] In some embodiments, Figure 1 The method may further include:

[0068] The laptop simulates load based on the hardware self-test instruction set, monitors the motherboard voltage drop, and forcibly adjusts the fan speed to the maximum value to detect the response delay of the temperature control system.

[0069] In some embodiments, the simulated load based on the hardware self-test instruction set and monitoring of the motherboard voltage drop may include:

[0070] Based on the hardware self-test instruction set, it sends complex computing task instructions to the CPU, starts multi-core computing to simulate load; sends graphics rendering instructions to the graphics card with a resolution and frame rate that meet preset conditions; and performs data read and write operations on the allocated memory space;

[0071] The voltage data of the key nodes of the mainboard are collected in real time at a pre-set sampling frequency, and the data is recorded. At the same time, the data is analyzed to determine whether a voltage drop occurs, and the amplitude, duration and occurrence time of the voltage drop are recorded.

[0072] In some embodiments, Figure 1 The method may further include:

[0073] The embedded controller adjusts the diagnostic process and parameters according to the user's operating habits, diagnostic results and device status changes during each diagnostic process to improve the efficiency and accuracy of the diagnosis.

[0074] In a specific example, since the processor debug serial port includes TXD, RXD, and GND signals, this design uses the processor debug serial port and the standard USB interface to multiplex. By default, the interface is in USB function, and only when the switching condition is triggered will the interface switch to debug function;

[0075] Since the notebook has a local matrix keyboard, and the matrix keyboard is controlled by an EC (embedded controller), a combination of keys is selected as the switching trigger condition, that is, the above-mentioned diagnostic trigger instruction;

[0076] The USB interface is used as the multiplexing function interface, and the default function is USB;

[0077] Use a combination of keys that have no specific meaning in actual applications and are not easy to trigger at the same time as the switching trigger condition. In a specific solution, this design can use the combination of ALT, B, and O keys as the trigger condition, such as Figure 2 As shown, the combination of the above three keys has no specific meaning in actual application, and the distance between them is relatively far, making it difficult to trigger them at the same time.

[0078] Figure 3 This is a block diagram of a USB2.0 signal and a debug serial port signal switching implementation provided by an embodiment of the present disclosure. Figure 3 As shown in the figure, in hardware implementation, in order to realize the switching between USB2.0 signal and TTL level debugging serial port, this design can use SGM77222 analog switch to implement this function, or use analog switch with similar functions. The analog switch must be able to meet the design requirements of USB2.0 signal.

[0079] In terms of logic design, after the EC is powered on, the default USB2.0 signal path is selected to the standard USB interface. After booting up, when the ALT+B+O shortcut key is pressed, it detects the diagnostic trigger command mentioned above, and the EC controls the GPIO level change to select the TTL level debug serial port path to the standard USB interface. As long as the EC is powered on, the GPIO signal level of the control switch remains in the previous state. At this time, while the EC is powered on, press the ALT+B+O shortcut key again to switch to USB2.0 signal.

[0080] The present disclosure multiplexes the processor debugging serial port with the standard USB interface, and can conveniently implement online diagnosis of the processor operation status without adding additional interfaces.

[0084] The embedded controller 402 is further configured to control the GPIO level change based on the diagnosis trigger instruction received again, so as to select the USB 2.0 signal path to the standard USB interface.

[0085] In some embodiments, the diagnosis trigger instruction is determined based on the distance between keys on the matrix keyboard and palm parameters of the human body.

The diagnostic method according to claim 7, characterized in that The simulating load based on the hardware self-test instruction set to monitor the motherboard voltage drop includes: Based on the hardware self-test instruction set, a complex computing task instruction is sent to the CPU to start multi-core computing to simulate load; a graphics rendering instruction with a resolution and frame rate that meet preset conditions is sent to the graphics card; and data reading and writing operations are performed on the allocated memory space; The voltage data of the key nodes of the motherboard is collected in real time at a pre-set sampling frequency, and the data is recorded. At the same time, the data is analyzed to determine whether a voltage drop occurs, and the amplitude, duration and occurrence time of the voltage drop are recorded.

9. The diagnostic method according to claim 1, wherein The method further comprises: The embedded controller adjusts the diagnostic process and parameters according to the user's operating habits, diagnostic results and device status changes during each diagnostic process to improve the efficiency and accuracy of the diagnosis.

10. A device for online diagnosis of the status of a notebook computer without disassembly, characterized in that: The device comprises: A receiving module is used to receive a diagnosis trigger instruction input by a user based on a matrix keyboard; An embedded controller, configured to control a GPIO level change based on the diagnostic trigger instruction, so as to select a TTL level debugging serial port path to a standard USB interface; The embedded controller is further used to control the GPIO level change based on the diagnosis trigger instruction received again, so as to select the USB2.0 signal path to the standard USB interface.
