CompTIA A+ Core 1 (220-1201) — Question 5

A help desk technician inspects a laptop keyboard because a single key has stopped working. The technician checks the keyboard for debris. Which of the following actions should the technician do next to troubleshoot the issue cost-effectively?

Answer options

• A. Replace the keyboard.
• B. Replace the key switch.
• C. Replace the circuit board.
• D. Replace the keycap.

Correct answer: D

Explanation

The correct answer is D because replacing just the keycap is often the least expensive and easiest solution when a single key is not working. The other options involve higher costs and more complex repairs that are unnecessary if the issue is merely a malfunctioning keycap.
