CompTIA A+ Core 1 (220-1201) — Question 158

A customer's laptop has been randomly shutting down. The laptop charges intermittently, and the screen dims when the laptop is not charging. Which of the following is the most likely cause of the issue?

Answer options

• A. Malware
• B. Failed digitizer
• C. Faulty battery
• D. Damaged power port

Correct answer: C

Explanation

The correct answer is C, as a faulty battery can lead to power issues, causing the laptop to shut down unexpectedly and not hold a charge. Options A, B, and D are less likely to be the cause, as malware typically leads to performance issues, a failed digitizer affects touch input, and a damaged power port would not explain the dimming screen behavior.
