You can use a Dell laptop's touchpad - or its built-in mouse pad - in place of an external mouse. You can use the touchpad to move around the screen or to click on icons. But sometimes the touchpad can become unresponsive or slow to respond. The reasons for this could be the touchpad is dirty, settings are wrong or you may need to update the drivers for the touchpad that are available on Dell's website.

Turn off the laptop by holding the power button down for 15 seconds. Unplug everything except for the power cord. This includes speakers, printers, USB flash drives, external monitor, keyboard and mouse, scanners and PDAs. Make sure the touchpad is clean and has no dirt, grease or food on it. You can wipe the touchpad off with a damp cloth with a small amount of alcohol. Wipe gently, then turn the laptop back on.
