When the computer touch screen does not respond, you can troubleshoot and solve it from the following aspects: 1. Check the touch screen switch
1. Confirm the status of the touch screen switch: Confirm whether the touch screen switch has been turned on. For most laptops, touchscreens typically come with independent switches that can be controlled through combination keys on the keyboard (such as Fn+F6, Fn+F10, etc., depending on the computer model). 2、 Check system settings
1. View Device Manager: In Windows systems, you can use Device Manager to view the status of touch screen devices. Open the Device Manager, locate and expand "Human Interface Devices" or "Anthropological Input Devices", check for touch screen devices, and confirm if their status is "Normal".
2. Check system settings: Enter system settings to see if any touch screen settings options have been disabled or modified. For example, in the Windows system, relevant settings can be checked through "Settings" ->"Devices" ->"Touchpad". 3、 Update or reinstall the driver program
1. Update driver: If the touch screen driver is outdated or damaged, it may cause the touch screen to malfunction. In the Device Manager, locate the touchscreen device, right-click and select "Update Driver", and then follow the prompts to operate.
2. Reinstall driver: If the problem persists after updating the driver, you can try uninstalling the original driver and reinstalling it. Before uninstalling, please ensure that you have downloaded the latest drivers suitable for your computer model. 4、 Check for hardware malfunctions
1. Check the appearance of the touch screen: Gently tap the area around the touch screen to see if there are any signs of looseness or damage. But please be careful not to apply too much force to avoid damaging other components.
2. Try connecting external devices: If possible, try connecting the touch screen to another computer for testing to determine if it is a problem with the touch screen itself. 5、 Other solutions
1. Cleaning the touch screen: If there is dirt or dust on the surface of the touch screen, it may affect its sensitivity. Gently wipe the surface of the touch screen with a clean and soft cloth to ensure that there are no residues.
2. Check for viruses and malware: Sometimes viruses or malware in the computer may interfere with the normal operation of the touch screen. Use antivirus software to conduct a comprehensive scan of the computer to ensure system security.
3. Run fault diagnosis program: If none of the above methods can solve the problem, you can try running the system's built-in fault diagnosis program or third-party hardware detection tool to find the problem. 6、 Contact professional maintenance
If none of the above methods can solve the problem, it is recommended to contact a professional computer repairman for inspection and repair. They can diagnose problems and provide corresponding solutions through professional equipment and technical means.
When the computer touch screen does not respond, do not panic and follow the above steps to troubleshoot and solve the problem one by one. If the problem still exists, seeking professional help in a timely manner is a wise choice.
