CompTIA A+ Core 1 (220-1101) — Question 70

A user brings an older laptop to the help desk and reports issues with the keyboard. Upon inspection, the technician does not see any external damage but notices that many keystrokes do not register in a word processor. The laptop works fine when the technician tests it with an external keyboard. Which of the following actions would MOST likely resolve the issue?

Answer options

• A. Disable the sticky keys feature.
• B. Clean the keyboard.
• C. Reset the BIOS settings to default.
• D. Charge the laptop.

Correct answer: B

Explanation

Cleaning the keyboard is likely to resolve the issue because debris or dust under the keys can prevent them from registering properly. The other options are less relevant; disabling sticky keys may not impact regular keystrokes, resetting BIOS settings does not address keyboard hardware issues, and charging the laptop is unnecessary if the device powers on and functions with an external keyboard.
