FC0-U71 Infrastructure Practice Question
A user reports that a laptop battery no longer holds a charge and the laptop shuts down immediately when unplugged. The laptop is several years old and the user wants to keep using it. Which of the following is the most appropriate replacement component?
⚠ Common exam trap
The trap here is attributing power loss to the adapter or motherboard when the specific symptom of immediate shutdown on battery power points to the battery itself.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A new laptop battery compatible with the model
A battery that no longer holds a charge and causes immediate shutdown when unplugged is failing and should be replaced with a compatible unit. Power adapters, motherboards, and RAM do not address battery capacity loss. Replacing the battery is the correct, targeted repair that restores portable use.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A new laptop battery compatible with the model
Why this is correct
The symptom of shutting down immediately when unplugged indicates the battery can no longer store or deliver power. Replacing it with a compatible battery restores portable operation. This is the direct fix for a worn-out battery and allows the user to continue using the laptop without replacing the entire system.
- ✗
A higher-wattage power adapter
Why it's wrong here
A higher-wattage adapter may charge faster or support a more demanding system, but it does not restore a battery that no longer holds a charge. The laptop already runs when plugged in, so the adapter is functioning. Replacing it would not solve the shutdown-when-unplugged behavior and could even be unsafe if the voltage is incorrect.
- ✗
An additional RAM module
Why it's wrong here
Adding RAM increases memory capacity and can improve multitasking performance, but it has no effect on battery charging or power retention. The laptop's shutdown when unplugged is a power issue, not a memory issue. This option does not address the root cause and would not restore battery operation.
- ✗
A replacement motherboard
Why it's wrong here
A motherboard replacement is a major repair that addresses logic or power-delivery faults on the board, not a degraded battery. The described symptom strongly points to the battery itself. Replacing the motherboard would be expensive, time-consuming, and unlikely to resolve the issue, making it an inappropriate recommendation.
