Quick Answer
The correct component to replace is the battery, as it is the only part responsible for storing and maintaining a charge when the laptop is unplugged. When a laptop battery no longer holds a charge, the chemical cells inside have degraded to the point where they cannot retain electrical energy, forcing the system to rely entirely on the power adapter. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of basic hardware roles and power management, often appearing as a straightforward troubleshooting question where the trap is confusing the battery with the power adapter—but the adapter still works, since the laptop runs when plugged in. A common memory tip is to think of the battery as a rechargeable fuel tank: if the tank leaks, you must replace it, not the fuel pump or the engine. Remember the mnemonic “B for Battery, B for Broken charge” to quickly link the symptom to the correct fix.
This FC0-U61 practice question tests your understanding of infrastructure. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user's laptop battery no longer holds a charge and the laptop only works when plugged in. Which component should be replaced?
Battery
The battery is the component that holds charge and needs replacement when it fails.
RAM
Why wrong: RAM is temporary memory and does not affect battery life.
Hard drive
Why wrong: The hard drive stores data, not power.
Power adapter
Why wrong: The power adapter charges the battery but does not store charge.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Battery
Option D is correct because the battery is the component that stores charge. The hard drive (A), RAM (B), and power adapter (C) do not affect battery charging.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Hard drive
Why it's wrong here
The hard drive stores data, not power.
Power adapter
Why it's wrong here
The power adapter charges the battery but does not store charge.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
