Cevap

Test the theory to confirm whether the power strip switch is turned off.
Following the standard CompTIA troubleshooting methodology, once a technician establishes a theory of probable cause (Step 2), the mandatory next step is to test the theory to confirm or disprove the cause (Step 3). Checking the power strip switch directly tests the established theory.
