    2. Trouble Shooting Models This topic covers the following Comp TIA A+ Essentials (2006) exam objective Identify tools, diagnostic procedures, and trouble shooting techniques for personal computer components. Recognize the basic aspects of trouble shooting theory, e.g. Perform backups before making changes Assess a problem systematically and divide larger problems into smaller components to be analyzed individually Verify even the obvious, determine whether the problem is something simple and make no assumptions. Research ideas and establish priorities. Document findings, actions and outcomes.

    3. Trouble Shooting Models cont’d Identify and Apply basic diagnostic procedures and troubleshooting techniques, e.g. Identify the problem including questioning user and identifying user changes to computer. Analyze the problem including potential causes and make an initial determination of software and /or hardware related problem. Test related components including section connections, hardware/software configurations, device manager, and consult vendor documentation Evaluate results and take additional steps such as consultation, use of alternative resources, manuals Document activities and outcomes

    4. Trouble Shooting What is trouble shooting? Trouble shooting is the process of determining the cause and ultimately the solution to a problem. By applying a logical , consistent method to the trouble shooting process, you make you job easier and shorten the time it takes to discover the root of the problem. Popular Models of Troubleshooting: The Comp TIA A+ troubleshooting model The Comp TIA A+ Network+ troubleshooting model The Novell network troubleshooting model The ASID trouble shooting model

    5. Trouble Shooting cont’d All models incorporate basic troubleshooting theory. The stages of basic troubleshooting theory include: Backup data Divide and analyze Verify Research Document

    6. 1. Comp TIA A+ Troubleshooting Model Steps Identify the problem Analyze the problem including potential causes Test components related to the problem Evaluate the results and take additional steps to correct the problem necessary Document the activities you took in correcting the problem as well as out comes of the actions you took.

    7. 2. Comp TIA’s Network+ Troubleshooting Model Comp TIA recommends a troubleshooting model for network technicians. You can follow this process for computer repair as well . It consists of 8 stages: Stages: Identify the exact issue , use open ended questions to query the customer to determine the precise nature of the problem. Re-create the problem, Have the customer repeat the action or demonstrate the problem. Isolate the cause, eliminate factors that obviously not part of the problem. Then starting with the most likely cause of the problem, begin to identify the cause. Formulate the correction, implement the correction . If this does not solve the problem undo everything you have done and try another approach. Test the solution; make sure your solution actually fixed the problem, double check with your client , make sure that your solution does not cause other problems. Document the problem and solution Provide feedback.

    8. 3. Novell’s troubleshooting Model Novell the maker of the popular NetWare network OS, publishes trouble shooting model for network technicians. STEPS Try some quick obvious fixes: like making sure all the peripherals are plugged in and turned on or the user is performing the procedure correctly. Gather basic information: determine the exact symptom of the problem. Determine whether the system worked correctly before, and if so what has changed . Check is others are having the same problem. Develop a plan, prioritize possible solutions Execute your plan Verify user satisfaction Document the problem and solution

    9. 4. The ASID troubleshooting model The ASID trouble shooting model offers a four stage process that you can apply to many types of problems. Its Stages are: Acquire — Acquire information about the problem Simplify -- Remove any non critical components Implement—Identify and implement potential solutions one at a time. Document— Document the problem and its resolution DOCUMENTATION Paper or software Organizational scheme Level of detail
