Troubleshooting a Non-Responsive Touchscreen: Driver Check

This 220-1201 practice question tests your understanding of display devices. 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 technician is setting up a new all-in-one PC for a reception desk. The PC has a touchscreen display. After installation, the touch function does not respond. The technician has verified that the display works and the OS is loaded. What should the technician check first?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "first"

    Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

Quick Answer

The answer is to check if the touchscreen driver is installed in Device Manager. This is the correct first step because a non-responsive touchscreen on a working display almost always points to a missing or corrupted driver rather than a hardware failure; the display itself is functional, so the issue lies in the software layer that translates touch input into system commands. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of the OSI model’s driver layer and the troubleshooting methodology—specifically, verifying driver installation before moving to hardware diagnostics. A common trap is immediately assuming the touchscreen is defective or needs calibration, but the exam emphasizes checking Device Manager first for any yellow exclamation marks or unknown devices. Remember the mnemonic: “If the screen lights but the touch won’t write, check the driver before you fight.”

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

Check if the touchscreen driver is installed in Device Manager

The most common reason a touchscreen fails to respond after a working display and OS load is a missing or incorrect driver. In Windows, the touchscreen driver appears under 'Human Interface Devices' in Device Manager; if it's not present or has a yellow exclamation mark, the OS cannot interpret touch input. Checking Device Manager is the quickest, non-invasive first step before considering hardware replacement.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Replace the touchscreen digitizer

    Why it's wrong here

    This is a hardware repair step, not a first check, especially when drivers are a common cause.

  • Check if the touchscreen driver is installed in Device Manager

    Why this is correct

    Missing or incorrect drivers are the most common cause of touchscreen non-functionality.

    Clue confirmation

    The clue word "first" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Clean the screen with a microfiber cloth

    Why it's wrong here

    Dirt rarely causes total touch failure; this is unlikely to resolve the issue.

  • Disable and re-enable the touchscreen in BIOS

    Why it's wrong here

    BIOS settings are less likely the cause; driver issues are more common.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may jump to hardware replacement (digitizer) or BIOS settings, overlooking the fundamental troubleshooting step of verifying the driver in Device Manager, which is the most common cause of a non-functional touchscreen after a fresh OS installation.

Detailed technical explanation

How to think about this question

Touchscreens on all-in-one PCs typically use a USB HID (Human Interface Device) protocol to communicate touch coordinates to the OS. If the driver is missing, the device may appear as an 'Unknown USB Device' or not at all in Device Manager. In some cases, the driver may be present but corrupted, requiring a reinstall from the manufacturer's support site rather than a generic Windows update.

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.

TExam Day Tips

  • 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.
