Computer System Self-Diagnosis Using Internal Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing methods for computer systems require external instruments and dismounting, leading to inefficiencies and inaccuracies, especially in systems with complex issues like faulty heaters under low temperatures, which are not addressed by existing tools designed for single component testing.
Innovation Solution
An automatic testing device and method that uses internal components like a recording module, connection interface, and power control module to test electric components within a computer system without dismounting, by recording battery-related status and determining component functionality through voltage and current measurements, with the ability to detect malfunctions and alert users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If external instruments and dismounting are used for testing, then testing can be performed on circuit boards and components, but testing efficiency is low and the process is troublesome
Solution Approach 1:
The computer system performs self-diagnosis by using its own internal components (CPU, memory, I/O interfaces) to test itself without requiring external testing instruments or dismounting, thereby improving testing efficiency and simplifying the testing process
Solution Approach 2:
The testing device integrates multiple testing functions into a single system that can test various components (heater, hard disk, CPU, memory) and modes (cold start, warm start, power on) through a unified self-diagnosis mechanism, eliminating the need for multiple external testing tools
2Measurement precision
If single component testing software is used, then specific components can be tested, but system-level issues such as poor wiring or configuration cannot be detected
Solution Approach 1:
The testing system performs comprehensive system-level diagnosis by testing not only individual components but also their interactions, wiring, and configurations through integrated self-diagnosis routines that cover the entire computer system
Solution Approach 2:
The system uses feedback from I/O interfaces and status registers to detect system-level issues such as poor wiring or configuration errors by monitoring signal integrity and component communication during the self-diagnosis process
3Measurement precision
If manual testing with external instruments is used, then detailed component status can be checked, but testing time is excessive and accuracy may be compromised
Solution Approach 1:
The system performs preliminary self-diagnosis by checking component status registers and I/O interface states during initialization or designated modes, enabling fast detection of component failures without time-consuming manual measurements
Solution Approach 2:
The system replaces manual mechanical testing with automated electronic self-diagnosis by using software-controlled I/O interfaces to read component status registers and detect failures, thereby reducing testing time while maintaining or improving accuracy

AI summary
An automatic testing device and method are provided to automatically test a computer system that has an electric component and a battery. First of all, a power control module controls the electricity supplied from the battery to the electric component. Next, when the computer system enters a designated mode, a battery-related component status is retrieved from a recording module through a connection interface. Afterwards, according to the battery-related component status, the computer system obtains testing information to determine whether the electric component operates normally. Since the power control module, the connection interface and the recording module are internal elements commonly configured computer system, the proposed device and method facilitate the testing tasks without any external instruments.
