CompTIA A+ Core 1 (220-1001) — Question 266

A user powers on a laptop and receives a message that it is under power. Which of the following should the user check FIRST?

Answer options

• A. The surge protector
• B. The power cord
• C. The power adapter
• D. The power cable length

Correct answer: C

Explanation

The correct answer is C, as the power adapter is crucial for converting electrical power for the laptop. If the adapter is malfunctioning or not providing sufficient power, the laptop will not charge properly. Checking the surge protector, power cord, or power cable length may be helpful, but they are secondary to ensuring the power adapter is functioning correctly.
