Laptop Touch Screen Not Working: Troubleshooting and Solutions

The touch screen on a laptop is often one of its most coveted features, providing users with a more interactive experience and ease of navigation. However, like all technology, touch screen functionality can sometimes fail. This can be frustrating, particularly if you’re accustomed to using the touch features for productivity or leisure. In this comprehensive article, we will explore various reasons your laptop touch screen may stop working and provide detailed troubleshooting steps and solutions.

Before we delve into troubleshooting, it’s crucial to understand how laptop touch screens work. Most laptops today utilize capacitive touch screen technology, which relies on the electrical properties of the human body to detect touch. When you touch the screen, it alters the electrical field, allowing the device to know the exact location of the touch. This system is usually integrated with drivers and software that interpret this data to function correctly.

While most laptops use capacitive technology, understanding the type can help in troubleshooting.

There are several reasons why a laptop’s touch screen might stop working. The issues can be broadly categorized into hardware and software problems.

Before diving into detailed troubleshooting, consider the following:


  • Restart your Laptop

    : A simple restart can sometimes resolve many issues.

  • Check for External Conditions

    : Ensure that there are no external objects, such as a stylus or other devices, interfering with the screen.

  • Inspect the Screen for Physical Damage

    : Look for cracks, scratches, or signs of liquid exposure.

  • Clean the Screen

    : Clean the touch screen with a microfiber cloth to remove any dirt or smudges that might obstruct touch sensitivity.

Sometimes, the issue may lie in the device’s settings. Here’s how to check touch screen settings:


  • Windows Devices

If the touch screen stopped working after a recent update, consider rolling back to a previous version:


  • For Windows

    :

    1. In Device Manager, find the “HID-compliant touch screen”.
    2. Right-click and select “Properties.”
    3. In the Driver tab, click “Roll Back Driver,” if the option is available.

If touch inputs are not registered accurately, you may need to calibrate the touch screen:


  • For Windows

    :

    1. Search for “Calibrate” in the Start menu.
    2. Select “Calibrate the screen for pen or touch input.”

Ensuring that your operating system is updated can resolve conflicts that affect touch functionality:

If the touch screen was functioning well before a certain point, a system restore might help:

Certain applications can interfere with the touch screen’s performance. Booting in Safe Mode can help diagnose if third-party software is the culprit:

  • Restart your laptop and boot into Safe Mode.
  • Check if the touch screen works normally in Safe Mode.

Sometimes, external USB devices can interfere with drivers. Disconnect all peripherals and restart your laptop to see if the touch screen issue resolves.

If all else fails, it may be time to seek professional assistance. Several factors may be beyond the capabilities of home troubleshooting, such as:

While some issues may be unavoidable, there are steps you can take to minimize the occurrence of touch screen problems:


  • Regular Software Updates

    : Keep your drivers and operating system up to date.

  • Clean Your Screen

    : Regularly clean the screen to prevent debris buildup.

  • Avoid Physical Damage

    : Use protective cases and be cautious of how you handle your laptop.
