Problems solved by technology

Therefore, when the notebook computer breaks down, the user can only send the broken notebook computer back to the original factory for inspection, but cannot judge the cause of the failure by himself.

Embodiment Construction

[0020] Please refer to figure 1 , which is a flow chart of a computer startup debugging method according to an embodiment of the present invention. The computer boot debugging method allows the user to input guessing signals through the input device to obtain the POST code or the device information corresponding to the POST code. The computer startup debugging method 100 includes the following steps:

[0021] In step 110, a POST is started. Wherein, the power-on self-test is used to perform a series of detection actions on the computer's processor, display card, memory, disk drive, optical drive, chipset, keyboard and other devices on the computer to detect whether the devices are working normally. Each functional test will be assigned a POST code, and the definition of the POST code varies with each manufacturer.

[0022] Next, during the POST execution, a POST function test is performed (step 130 ) to detect a device on the computer. When executing the function test (ste...

Abstract

The invention relates to a computer startup error debugging method. Specifically, a computer boot error debugging method includes the following steps: start to execute a power-on self-test; execute a plurality of functional tests of the power-on self-test one by one, wherein when performing a plurality of functional tests of the power-on self-test one by one, the executed The codes corresponding to each function test of each function test are stored in a memory; when the power-on self-test is interrupted, the user inputs a guessing signal through an input device; and at least one stored code stored in the memory is obtained according to the guessing signal. The present invention can judge the cause of the failure of the computer according to the power-on self-test code or the device information corresponding to the power-on self-test code without adding additional seven-segment LED subtitles or inserting a debug card.

Description

technical field [0001] The invention relates to a debugging method, and in particular to a computer startup debugging method. Background technique [0002] When the computer is booting up, it will first perform a Power On Self-Test (POST) through a Basic Input / Output System (BIOS). Among them, POST is used to perform a series of detection actions on the processor, display card, memory, disk drive, CD drive, chipset, keyboard and other computer peripheral devices, so as to detect whether the peripheral devices are working normally. [0003] During the POST process, the BIOS will store the power-on self-test code (or POST Code information) corresponding to each hardware test process into the I / O port 80h (input and output port 80h) address when testing each hardware. In this way, when a hardware fault is detected, the user can determine the problem of the computer by reading the POST code in the I / O port 80h. [0004] The prior art is to read the power-on self-test code from...
