As technology evolves, touch screens have become a prevalent feature in modern computers, offering a more interactive and intuitive user experience. However, when a computer touch screen fails to respond, it can disrupt productivity and cause significant frustration. In this comprehensive guide, we will explore the common reasons why a computer touch screen might not work and provide detailed troubleshooting steps to resolve these issues. Follow these steps carefully to restore the functionality of your touch screen.

1. Restart Your Computer

The first and simplest step to troubleshoot any issue with your touch screen is to restart your computer. A restart can resolve minor software glitches or temporary malfunctions that might be affecting the touch screen’s responsiveness.

1. Save your work: Ensure all your files and documents are saved to avoid data loss.
2. Restart the device: Click on the Start menu, select the Power icon, and choose “Restart.”
3. Check the touch screen: After the computer reboots, test the touch screen to see if it is functioning correctly.

If the touch screen still does not respond, proceed to the next steps for further troubleshooting.

2. Check for Software Updates

Outdated software can lead to compatibility issues, which may cause your touch screen to malfunction. Ensuring your operating system and touch screen drivers are up to date is essential for optimal performance.

How to Check for Updates on Windows:

1. Open Settings: Click the Start menu and select “Settings.”
2. Go to Update & Security: Navigate to “Update & Security.”
3. Check for updates: Click “Check for updates” to allow the system to search for any available updates.
4. Install updates: If updates are found, follow the on-screen instructions to install them. Once installed, restart your computer to apply the changes.

How to Check for Updates on macOS:

1. Open System Preferences: Click the Apple menu and select “System Preferences.”
2. Go to Software Update: Click on “Software Update.”
3. Check for updates: The system will automatically search for available updates. If any are found, click “Update Now” to install them.
4. Restart your Mac: After the update process is complete, restart your computer.

After updating your system and drivers, test the touch screen again. If it still does not work, continue to the next step.

3. Clean the Touch Screen

Dirt, grease, and dust can accumulate on the touch screen over time, which may interfere with its sensitivity and responsiveness. A thorough cleaning can often resolve this issue.

Cleaning Steps:

1. Turn off your computer: Before cleaning, ensure the device is powered down to prevent any accidental inputs or damage.
2. Use a microfiber cloth: Dampen a microfiber cloth with water or a screen-safe cleaning solution. Avoid using harsh chemicals, as they can damage the screen.
3. Wipe the screen gently: Use the dampened cloth to gently wipe the touch screen in a circular motion, removing any fingerprints, smudges, or debris.
4. Dry the screen: Use a dry microfiber cloth to remove any remaining moisture from the screen.

Ensure the screen is completely dry before turning the computer back on. Test the touch screen again to see if the cleaning has improved its functionality.

4. Remove Screen Protectors and Accessories

Sometimes, screen protectors or other accessories can interfere with the touch screen’s sensitivity. If you have a screen protector installed, try removing it to see if it resolves the issue.

How to Safely Remove a Screen Protector:

1. Power off your device: Turn off the computer to avoid accidental inputs.
2. Lift the screen protector: Carefully lift the screen protector from one corner using a fingernail or a plastic card.
3. Remove slowly: Peel off the screen protector slowly to avoid leaving any residue on the screen.

If removing the screen protector resolves the touch screen issue, consider replacing it with one specifically designed for touch screen devices.

5. Calibrate the Touch Screen

Calibrating your touch screen can help improve its accuracy and responsiveness, especially if it does not register your touch correctly or has dead spots.

How to Calibrate a Touch Screen on Windows:

1. Open Control Panel: Click the Start menu, type “Control Panel,” and select it from the search results.
2. Navigate to Tablet PC Settings: In the Control Panel, search for “Tablet PC Settings” and click on it.
3. Calibrate the screen: Click the “Calibrate” button under the Display tab and follow the on-screen instructions to complete the calibration process.

How to Calibrate a Touch Screen on macOS:

For macOS users, calibration options are generally more limited. However, you can adjust touch screen settings through third-party calibration software or by adjusting touch sensitivity settings in the Accessibility options under System Preferences.

After calibration, check the touch screen’s functionality. If calibration does not resolve the issue, proceed to update the touch screen drivers.

6. Update Touch Screen Drivers

Drivers are essential for your hardware to communicate effectively with the operating system. Outdated or corrupted drivers can cause the touch screen to stop working. Updating these drivers can often resolve the issue.

Updating Touch Screen Drivers on Windows:

1. Open Device Manager: Right-click the Start menu and select “Device Manager.”
2. Locate the touch screen driver: Expand the “Human Interface Devices” section and locate the touch screen driver (usually labeled as HID-compliant touch screen).
3. Update driver: Right-click the touch screen driver and select “Update driver.” Choose “Search automatically for updated driver software” and follow the on-screen instructions.
4. Restart your computer: Once the driver update is complete, restart your computer to apply the changes.

Updating Touch Screen Drivers on macOS:

macOS generally manages driver updates through system updates. Ensure your macOS is up to date to maintain the latest drivers.

If updating the drivers does not fix the problem, further diagnostics may be necessary.

7. Check Touch Screen Settings

Incorrect touch screen settings could be another reason why your touch screen isn’t working. Checking and adjusting these settings might resolve the issue.

Checking Touch Screen Settings on Windows:

1. Open Control Panel: Go to the Start menu, type “Control Panel,” and open it.
2. Navigate to Pen and Touch: Click on “Hardware and Sound,” then “Pen and Touch.”
3. Adjust settings: Ensure that “Use your finger as an input device” is checked. You can also adjust other touch settings to your preference.

Checking Touch Screen Settings on macOS:

For macOS users, navigate to “System Preferences,” then “Accessibility,” and adjust any relevant settings under “Mouse & Trackpad” and “Touch Bar” options.

After adjusting the settings, test the touch screen to see if the issue is resolved.

8. Perform a System Restore

If the touch screen issue started after a recent update or software installation, performing a system restore might revert your system to a point where the touch screen was functioning correctly.

How to Perform a System Restore on Windows:

1. Open System Restore: Type “System Restore” in the Start menu search bar and select “Create a restore point.”
2. Choose a restore point: Click on “System Restore,” select a restore point before the issue began, and follow the prompts to complete the process.
3. Restart your computer: After the restore is complete, restart your computer and test the touch screen.

How to Perform a System Restore on macOS:

macOS users can use Time Machine to restore the system to a previous state. Ensure you have a backup available before proceeding with the restoration.

9. Contact the Manufacturer

If all the above steps fail to resolve the touch screen issue, it may be a hardware problem. In this case, contacting the manufacturer for further assistance or considering a professional repair may be necessary. Check your device’s warranty status before reaching out, as the repair might be covered under warranty.
