How to Troubleshoot Dell Laptop Touchpad
Dell is a computer company that produces a wide range of both desktop and laptop systems, most of which use the Microsoft Windows operating system. The laptop computers have a built in touchpad, instead of the older trackballs and cursor control buttons.This touchpad allows you to control the mouse cursor with your fingers. However, if you find the touchpad is acting up, and the cursor not following your finger movements or not moving at all, you need to troubleshoot the situation in order to correct whatever is causing the touchpad to not function properly. This problem ranges from the equipment being damp to the driver for the touchpad coming up missing on the computer system.Dry Dell Laptop TouchpadFirstly, dry off your hands. If your hands are wet the touchpad for the Dell laptop computer may not function correctly. In addition, the touchpad requires direct skin contact, so it is not going to function properly if you are wearing gloves or anything else on your fingertips.Warm up your hands. As with wet fingers, the laptop is unable to detect your finger strokes when either the touchpad or your fingers are extremely cold. Dell laptop touchpads are heat sensitive, so the equipment detects your finger movements by the head that is applied to the touchpad. This is why you are unable to use a touchpad with any cold object (such as a pen, pencil or other static device).Wipe off the touchpad with a clean cloth. If there is any dust or debris stuck to the touchpad, it prevents the touchpadfrom accurately reading your finger movements and may send your mouse in the opposite direction from your commands.Install Dell Laptop Touchpad DriverDownload the driver for your Latitude D620 touchpad. It is possible the driver to the touchpad was removed during a routine software cleanup or anti-virus sweep. You may need to connect an external mouse for this if your touchpaddoesn't work at all.Navigate to the Dell website, choose "Support," then select "Downloads and Drivers."Type in "Latitude D620" as the device you want, then choose "Installed Drivers." From the list click the touchpad option to download the updated driver. Once you have the driver downloaded onto your computer, double-click the driver to launch the installation wizard.Follow the short series of prompts to install the driver, restoring functionality to the touchpad. If you are unable to use the mouse at all to reach the driver download you can connect an external, USB based mouse to the laptop in order to perform the mouse duties. You can either borrow the mouse from a nearby desktop or purchase an inexpensive mouse from your local electronics store.
