CompTIA A+ Core 1 (220-1001) — Question 216

A customer accidentally drops a laptop while it is charging. The next day, the customer notices the laptop will not turn on and calls a technician to investigate. The technician confirms the laptop will not turn on even though it is connected to the power adapter.
Which of the following components is the MOST likely cause of this behavior?

Answer options

• A. Power adapter
• B. Battery
• C. DC jack
• D. Hard drive

Correct answer: C

Explanation

The most probable cause of the laptop not turning on after being dropped is a damaged DC jack, which connects the power from the adapter to the laptop. While the power adapter and battery may also fail, the physical impact of the drop makes the DC jack the most likely component to be affected. The hard drive is unrelated to power issues and would not prevent the laptop from turning on.
