- A
The touchpad driver has been corrupted by the liquid
Why wrong: Liquid does not corrupt drivers; it causes physical damage. The driver would still be intact unless the liquid damaged the storage, which is unlikely.
- B
The touchpad has been disabled in the BIOS due to a safety feature
Why wrong: No such safety feature exists in typical BIOS. The touchpad would not be automatically disabled by liquid detection.
- C
The liquid has damaged the touchpad or its ribbon cable
Liquid can short-circuit the touchpad's capacitive sensors or corrode the ribbon cable connector, causing the touchpad to stop working while the keyboard remains functional.
- D
The laptop's operating system has detected the liquid and disabled input devices
Why wrong: Consumer laptops do not have liquid detection that disables input devices. This is not a standard feature.
Quick Answer
The most likely cause is liquid damage to the touchpad or its ribbon cable. When coffee is spilled on a laptop keyboard, the liquid can seep beneath the keyboard surface and travel along internal pathways, often reaching the touchpad’s separate connector or the touchpad assembly itself before it reaches the main system board. Because the keyboard still functions, the liquid likely did not reach the motherboard, but the touchpad is a more exposed component with its own dedicated ribbon cable that is highly susceptible to short circuits and corrosion from conductive residue. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of component isolation and liquid damage progression—a common trap is assuming the entire input system fails together, but the keyboard working rules out motherboard damage. Remember the memory tip: “Coffee hits the pad, not the board”—if the keyboard still types, the liquid likely stopped short of the main logic board, isolating the fault to the touchpad or its cable.
220-1101 Mobile Devices Troubleshooting Practice Question
This 220-1201 practice question tests your understanding of mobile devices troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 reports that their laptop's touchpad is not working after they spilt a small amount of coffee on the keyboard. The keyboard still works, but the touchpad cursor does not move. What is the most likely cause?

Correct answer & explanation
The liquid has damaged the touchpad or its ribbon cable
Coffee can seep into the touchpad connector or the touchpad itself, causing a short or corrosion. The keyboard working suggests the liquid did not reach the main board, but the touchpad is a separate component that is more exposed. The correct answer is liquid damage to the touchpad.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 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.
