How to Disable a Dell Precision Laptop Touchpadby Tara Cantore
Dell Precision laptop computers come equipped with touch pads that use Synaptics Pointing Devices that operate through the Synaptics Touchpad software application and driver. If you have a USB or wireless mouse, you may find that the touchpad goes unused and accidentally brushing it disturbs the accuracy of your moues movements. You can disable the touchpad on all Dell Precision systems.
Open the Start menu and type "Device Manager" and then click "Device Manager" from the list of applications.
Scroll down to "Mice and Other Pointing Devices" in the Device Manager window and press the "+" symbol next to it to expand the tree-view.
Right-click "Synaptics PS/2 Port TouchPad" and click "Disable." The touch pad will be disabled until you return to this screen, right-click the TouchPad and then click "Enable."
