CompTIA A+ Core 1 (220-1101) — Question 524

A colleague has a laptop that has been working as expected for several years, but the laptop now has a small bulge in the bottom casing and overheats occasionally while plugged in to a wall outlet. The MOST likely component that needs to be replaced is the:

Answer options

• A. power adapter.
• B. battery.
• C. system fan.
• D. hard drive.

Correct answer: B

Explanation

The battery is the most likely component to be replaced because a bulge in the casing is often a sign of a swollen battery, which can also lead to overheating. The power adapter typically doesn't cause such physical changes, while the system fan and hard drive do not usually exhibit bulging and are less likely to cause overheating in this manner.
