how to disable touchpad on Latitude D620

This question has suggested answer(s)

How can I disable the touchpad on my Dell Latitude D620.  Just recently started having this problem.  When I am typing I guess I brush it with my thumbs and the cursor is jumping all over.  So very hard to type anything.

  • Remove the Keyboard and disconnect the cable to the track-pad which is separate from the keyboard.

    Removing the Keyboard

     CAUTION: Before working inside your Dell™ computer, follow the safety instructions in your Product Information Guide.

     CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface.

    1. Follow the instructions in Before Working Inside Your Computer.

    2. Remove the hinge cover (see Hinge Cover).

    3. Remove the three screws at the top of the keyboard.

     NOTICE: The keycaps on the keyboard are fragile, easily dislodged, and time-consuming to replace. Be careful when removing and handling the keyboard.

    1. Lift the keyboard and rotate it slightly forward to allow access to the keyboard connector on the system board.

    2. Disconnect the keyboard cable connector from the system board.


    Replacing the Keyboard

     NOTICE: To avoid scratching the palm rest when replacing the keyboard, hook the tabs along the front edge of the keyboard into the palm rest, and then secure the keyboard in place.

    1. To replace the keyboard, connect the keyboard connector to the system board.

    2. Place the tabs along the front edge of the keyboard into the palm rest and lay the keyboard down on the palm rest.

    3. Replace the three screws at the top of the keyboard.

    4. Replace the hinge cover (see Hinge Cover).

  • Hi Ll60200,

    Welcome to the Community. The Latitude D620 does not have a function key to temporarily disable the touchpad. However you can disable the touchpad, by click on start, control panel, mouse, click on the Dell Touchpad Image, click on device select, and you have an  option to disable the touchpad there. If you use an external mouse instead of the touchpad, you also have an option there to disable touchpad when USB mouse connected.

    Hope this helps.

    Thank you
