CompTIA A+ Core 1 (220-1001) — Question 412

An employee's laptop will not power on. When the power button is pressed, the power light goes on and then suddenly off. A technician replaces the battery, and the laptop powers on. The employee works without issues until the end of the day, but the laptop presents the same problem the next morning.
Which of the following is the MOST probable cause of the issue?

Answer options

• A. Swollen battery
• B. Damaged AC adapter
• C. Improperly seated RAM
• D. Cooling fan failure
• E. Imminent hard drive failure

Correct answer: B

Explanation

The most likely reason for the recurring issue is a damaged AC adapter, which may not provide consistent power to the laptop. A swollen battery could cause initial problems, but since it was replaced and the laptop worked for a day, it is less likely to be the cause. The other options, such as improperly seated RAM, cooling fan failure, and imminent hard drive failure, would not typically cause the specific symptoms described.
