CompTIA A+ Core 1 (220-1001) — Question 113

An end user brings in a laptop that no longer charges. A technician troubleshoots the laptop and notices it works while the power adaptor is plugged in but shuts down as soon as it is unplugged.
Which of the following is the NEXT best step to resolve this issue?

Answer options

• A. Plug the laptop into another power outlet.
• B. Replace the power adaptor.
• C. Replace the laptop's battery.
• D. Plug the laptop into a UPS.

Correct answer: C

Explanation

The correct answer is C, as the laptop's battery is likely faulty and unable to hold a charge, which is why it powers off when unplugged. Options A and D do not address the underlying battery issue, and while B suggests replacing the power adaptor, the adaptor is functioning since the laptop operates when plugged in.
