On today’s Tech, No Babel: Troubleshooting Techniques: Using the Scientific Method

Asking a question: What is the cause of this problem?
Hypothesis: What you think it is
Prediction: If this is true, what is also true
Testing: Seeing if this aligns with reality
Analysis: Seeing if the hypothesis is correct

Repeat: If you’re correct, the results should be repeatable under identical circumstances.

Example: Switcher doesn’t work at all, no lights nothing.

Question: Why doesn’t it work at all?
Hypothesis: The outlet isn’t working
Prediction: If the outlet isn’t working, plugging the switcher into another, should cause it to work. Likewise, plugging something else into this outlet should cause that something not to work.
Testing: Plug switcher into another outlet, plug a known working piece into that outlet.
Analysis: Switcher works in new outlet. Lamp works in suspected bad outlet. Outlet isn’t the cause of the failure, unless it’s not sending enough electricity to power the switcher, but is for the lamp.

Repeat: Check if cord has an intermittent short, if switcher now works in the suspected bad outlet, etc.
