CompTIA A+ Chapter 1 What is the first step in the six step troubleshooting process? - ✔✔Identify the problem. How should you identify a problem? - ✔✔Question the user, identify any changes ... made to the computer, and review documentation. What is step two of the troubleshooting process? - ✔✔Establish a theory of probable cause. What is the third step in the troubleshooting process? - ✔✔Test the theory to determine cause. What happens if your first theory fails? What happens if all theories fail? - ✔✔If the first theory fails, go back to step two and establish a different theory. If all theories fail, escalate. What is the forth step of the trouble shooting process? - ✔✔Establish a plan of action to resolve the problem and implement a solution. What is the fifth step of the troubleshooting process? - ✔✔Verify full system functionality and, if applicable, implement preventative measures. What is the final step of the troubleshooting process? - ✔✔Document findings, actions, and outcomes. What should you do before making any changes to the computer? - ✔✔Perform a backup.

I would then take preventative measure to ensure that the problem would not occur again. What would your preventative measures be? - ✔✔I would either move a computer to another outlet, or contact an electrician to install a new circuit. What should you do after taking preventative measures? - ✔✔Document the findings, actions, and outcomes. What are field replaceable units (FRU)? - ✔✔Power supplies, hard drives, and RAM. What are the tools you should have in your toolkit? - ✔✔1. antistatic strap, 2. demagnetized Philips head screwdriver, 3. multimeter, 4. power supply tester, 5. torx screwdrivers, 6. hex screwdrivers, 7. plastic tweezers, 8. compressed air, 9. penlight, 10. magnifying glass What do antistatic straps protect fro [Show More]
