The touchpad on a Dell Latitude D630 laptop is a square pad just below the keyboard that you run your fingers across to navigate the computer. This can be a convenient feature, but many people like to connect a mouse to their laptops and use that instead of the touchpad. If you'd rather use a mouse than a touchpad, you can disable the pad via the "Mouse Properties" setting.
Turn on the Dell Latitude D630. Click on the "Start" tab in the left corner of the toolbar located at the bottom of the computer screen.
Select "Control Panel" from the list of options in the drop-down menu, and a new window will appear with a new set of options.
Select "Mouse" from the list of options. The "Mouse Properties" window will appear on screen. Click on the "Device Select" tab in the window to disable the touchpad.
Click "Yes" when prompted to confirm, and the touchpad on your Latitude will be disabled.
