If you’ve recently reinstalled Windows or completed a system recovery on your Dell Inspiron laptop, you may need to reinstall the touchpad driver. System changes or a corrupted driver may leave the touchpad unusable, making an external mouse a necessity for quick navigation. The touchpad driver enables you to use the built-in touchpad and control its settings. Download the Dell Inspiron touchpad driver from Dell’s website or use a Dell driver disc to reinstall the driver.
