CompTIA A+ Core 1 (220-1001) — Question 368

A user brings in 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

The most probable solution is to clean the keyboard, as dirt or debris can obstruct the keys, causing them not to register correctly. Disabling the Sticky Keys feature would not address the hardware issue, resetting the BIOS settings is unlikely to resolve keyboard registration problems, and charging the laptop is irrelevant since the device powers on and operates normally with an external keyboard.
