Try this.( you need a temporary USB mouse for this procedure...unless your a keyboard shortcuts expert)Start.Right click on my computer.Properties.Hardware tab.Device Manager.Expand mice and pointing devices.Then you should see your touchpad listed.Right click on the touch pad and then hit update drivers.Then after updating restart computer. If it still does not work then go back to device manager and right click on mouse pad and this hit properties and then hit trouble shoot.If both don't work sorry but you need to get your mouse pad replaced.Hope all this helps
