When the built-in mouse (touchpad) of the laptop does not respond, you can try the following steps to solve the problem:
1. Check touchpad switch: Some laptops have dedicated touchpad switches or function keys, which may be located on the keyboard or on the side of the laptop- Ensure that the touchpad switch is turned on and check if there are any other function keys that can enable or disable the touchpad.
2. Update or reinstall driver: - The touchpad requires the correct driver to function properly- Go to the official website of the laptop manufacturer, download and install the latest touchpad driver- You can also try to find the touchpad driver in Device Manager, right-click and select "Update Driver" to update it.
3. Check device settings: - Go to the computer's settings or control panel and find the "Mouse" or "touchpad" settings options- Ensure that the touchpad function is enabled and not disabled by other settings.
4. Check hardware issues: If none of the above methods solve the problem, it may be due to a problem with the touchpad hardware itself- Try connecting the laptop to an external mouse to see if it works properly. If the external mouse can be used normally, it is likely that there is a problem with the touchpad itself.
5. Cleaning the touchpad surface: - The touchpad may be affected by dust, dirt, or fingerprints, causing it to malfunction- Gently wipe the surface of the touchpad with a soft, clean cloth to remove any dirt.
6. Restarting the computer: Sometimes, simply restarting the computer can solve some temporary problems.
7. Update operating system: - Ensure that the operating system is the latest version and apply all available updates. Sometimes, updates to the operating system can fix issues with the touchpad.
If the above methods still cannot solve the problem, it is recommended to contact the manufacturer of the laptop or seek professional technical support for troubleshooting and repair. They can provide more specific guidance and offer solutions based on specific situations.
