Have you tried installing/reinstalling the software from Dell that controls the touchpad (assuming there is software released)? You might try that first just to see if its a hardware or software issue.
You might check in the Hardware Devices area and disable the touchpad. I don't know if on that model if there is an actual hardware driver that you can disable though. ( Rt. click My Computer, Click on Properties, Click on Hardware Tab, Click on Device Manager, expand Mice and Other Pointing Devices.)
You might also check the Mouse control panel ( Start --> Settings --> Control Panel) and see if there is something you can set in there.
You can also call Dell's Parts and Upgrades line (800-357-3355) and see how much a replacement touchpad would be. Cannot be too much I would imagine.
