If the touchpad fails to work after you tinker with the drivers and cleaning it, you can always plug in a separate mouse. I find that works best with me. I just can't get use to the little built in pointer or touchpad mouse.
i do use the external mouse more, i only use the touch mouse at night, so i dont wake up anyone, cause they're grumpy if there woken
Edit: oh yea, forgot to post it the first time, it works now, i cleaned it as good as i could and restarted.
