In your system you should be using synaptics touchpad driver. First of all look for it under mouse properties in control panel. If its not there then install in from support.dell.com. Under this application you would be having option to disable touchpad when external mouse connected. Try this.

Will your laptop work properly with an external mouse? If so, check your touchpad settings in "Control Panel" by selecting "Mouse". Here you can reassign your Buttons. Try setting your Right Button function to "Double Click". If the "Double Click" function works on your Right Button then chances are you have a problem with your Touchpad Assembly which means it will have to be replaced. Dell refers to it as a "Palmrest" which they will replace if still under warranty.

You should have a "FN" key on the keyboard and one of the "F" keys should have a symbol that looks like the touch-pad, hold FN while using this key should disable it, failing this in control panel, then mouse and pointers, you should have touchpad setting there should be a disable button/radius.

Hi MKW,

I know the feeling. Here we go,

1. Go to Control Panel
2. Click System
3. Click the Hardware Tab
4. Click Device Manager
5. Click the '+' located to the left of Mice and other controllers
6. There should be two mice listed. Select the touchpad.
7. Right Click it then click on Properties.
8. At the bottom where it says 'Device Usage', Change it to Disable.
9. Click OK until you're out.
10. If it wants to reboot, let it.
