Zorluk: OrtaTroubleshooting Methodology

A field technician is troubleshooting a mobile workstation that experiences sudden display flickering and unexpected shutdowns during heavy graphic rendering. The technician gathered user reports, established a theory that the GPU cooling intake was clogged, and tested the theory by verifying that thermal throttling occurred under load. The technician then cleaned the internal heat sink, reapplied thermal paste, and replaced the degraded cooling fan to resolve the issue. According to the CompTIA 6-step troubleshooting methodology, which step should the technician perform NEXT?

  1. Perform a complete system check and execute a prolonged graphics benchmark to verify full system functionality.Cevap
  2. B
    Document the initial symptoms, diagnostic findings, and component replacement details in the ticketing system.
  3. C
    Replace the display backlight inverter board to ensure stable high-voltage power delivery to the screen.
  4. D
    Reconfigure the network DNS server to renew the workstation's IP lease and prevent connection drops.

Cevap

Perform a complete system check and execute a prolonged graphics benchmark to verify full system functionality.
After implementing a solution (cleaning the heat sink, reapplying thermal paste, and replacing the cooling fan), the next step in the CompTIA 6-step troubleshooting methodology is to verify full system functionality and implement preventive measures. Running a prolonged graphics benchmark confirms that thermal throttling and unexpected shutdowns are fully resolved under operational load.

Adım Adım Çözüm

1
Identify the completed steps in the CompTIA troubleshooting methodology.
The technician identified the problem (Step 1), established a theory (Step 2), tested the theory (Step 3), and implemented the solution (Step 4).
Determining the current phase of the troubleshooting process identifies what action must immediately follow.
2
Determine the next sequential step in the 6-step model.
Following Step 4 (implement solution), Step 5 requires verifying full system functionality and implementing preventive measures if applicable.
Testing the system under actual operating conditions ensures the fix resolved the primary issue without introducing new problems.
