My mouse touchpad doesn't work.

1. Restart Your Laptop: Begin by restarting your Dell Latitude 7480. Sometimes, a simple restart can resolve minor software glitches that may be affecting the touchpad.
2. Check Touchpad Settings: Access your laptop's touchpad settings to ensure they are configured correctly. Go to the Control Panel or Settings menu, find the touchpad options, and verify that the left and right click functions are enabled.
3. Update Touchpad Drivers: Outdated or incompatible touchpad drivers can cause functionality problems. Visit Dell's official support website, enter your laptop's model (Latitude 7480), and download the latest touchpad drivers. Install them and restart your laptop to see if the issue is resolved.
4. Rollback Drivers: If you recently updated your touchpad drivers and encountered issues afterward, consider rolling back to the previous version. Open the Device Manager, locate the touchpad drivers, right-click on them, choose "Properties," go to the "Driver" tab, and select "Roll Back Driver." Restart your laptop to see if this resolves the problem.
5. Disable and Enable Touchpad: Temporarily disabling and re-enabling the touchpad can sometimes reset its functionality. Look for a dedicated touchpad button on your laptop's keyboard or use a keyboard shortcut (usually Fn + a function key) to disable and enable the touchpad.
6. Clean the Touchpad: Dust, dirt, or debris on the touchpad surface can interfere with its sensitivity and responsiveness. Use a soft cloth or microfiber cloth to gently clean the touchpad, removing any buildup that may be affecting its performance.
7. External Mouse Test: Connect an external mouse to your laptop and check if it works properly. If the external mouse functions correctly, it indicates that the issue lies specifically with the touchpad and not with general input devices or settings.
8. Check for Physical Damage: Inspect the touchpad area for any visible signs of physical damage. Look for loose connections or broken components. If you identify any damage, it is recommended to contact a professional technician or Dell support for repair or replacement options.
