Explanation

Swapping the battery with a known-good laptop of the same type is the best first step because it isolates the variable (battery vs. charging circuit) without requiring the system to be shut down, which would risk losing unsaved data. If the swapped battery charges normally, the original battery is faulty; if it still doesn't charge, the laptop's charging circuit is the problem. Option B (removing the A/C adapter while running) only tests if AC power is present, not the battery charge state. Options C and D both involve shutting down or removing power, which would erase unsaved data - directly violating the constraint in the question.
