Intended Learning Outcomes
At the end of the lesson, the student must be able to:
- Defined troubleshooting and hardware troubleshooting;
- Identified the procedures of troubleshooting method;
- Appreciate the importance of hardware troubleshooting.
Troubleshooting is the ability of individuals to adopt a systematic approach towards identifying and then solving the problem or issue (Mabiog, C., 2019). Hardware troubleshooting is the process of reviewing, diagnosing and identifying operational or technical problems within a hardware device or equipment. It aims to resolve physical and/or logical problems and issues within a computing hardware. Hardware troubleshooting is done by hardware or technical support technician. (Rouse, M. (2014)
Troubleshooting Method
Troubleshooting requires an organized and logical approach to problems with computers and other components. Asking the right questions, testing the right hardware, and examining the right data helps you understand the problem. This helps you form a proposed solution to try. Troubleshooting is a skill that you will refine over time. Each time you solve another problem, you will increase your troubleshooting skills by gaining more experience. (Ullah, I. 2010, as cited in Mabiog, C., 2019)
According to Ullah, 2010, these are the procedures of troubleshooting:
1. Explain the purpose of data protection.
2. Identify the problem.
3. Establish a theory of probable causes.
4. Test the theory to determine an exact cause.
5. Establish a plan of action to resolve the problem and implement the solution.
6. Verify full system functionality, and if applicable, implement preventive measures.
7. Document findings, actions, and outcomes. In this section, you will learn an approach to problem solving that can be applied to both hardware and software. You also can apply many of the steps to problem solving in other work-related areas.
Meanwhile, here's also a general guide since certainly, troubleshooting hardware involves a systematic approach.
1. Identify the Problem:
Clearly define the issue: What specific hardware isn't functioning as expected?
2. Check Physical Connections:
Ensure all cables and connections are secure.
Look for loose components or disconnected peripherals.
3. Power Cycle:
Turn off the hardware, wait a few seconds, then turn it back on.
Restart the computer or device to reset configurations.
4. Check Power Supply:
5. Ensure the device is receiving power.
Test with an alternate power source or outlet.
6. Run Diagnostic Tools:
Utilize built-in diagnostic tools or third-party software to identify hardware issues.
Check system logs for error messages.
7. Update Drivers and Firmware:
Ensure all drivers and firmware are up to date.
Visit the manufacturer's website for the latest updates.
8.Hardware Testing:
Use diagnostic tools to test individual hardware components (e.g., RAM, hard drive).
Run hardware diagnostics from the device's BIOS/UEFI.
9. Isolate the Issue:
Disconnect peripherals and test one component at a time to identify the problematic hardware.
10. Temperature Check:
Overheating can cause hardware malfunctions. Monitor temperatures and clean cooling systems if needed.
11. Check for Physical Damage:
Inspect hardware components for any physical damage.
Verify that all components are properly seated.
Remember to document your troubleshooting steps and any changes made, as this information can be valuable when seeking assistance or diagnosing more complex issues.
