1. Check your laptop’s system settings to make sure trackpad clicks are enabled.
2. Clean any debris or foreign substances from the surface of the trackpad.
3. Test if the trackpad clicks can be registered when using an external mouse.
4. Check to see if the trackpad settings have changed in your laptop’s mouse and touchpad settings.
5. Run a diagnostic to ensure all of your laptop’s hardware is functioning properly.
