I've tried EVERYTHING and looked for EVERYTHING in the control panel and everywhere else I know to look. I've had other laptops that I could disable the touch pad in no time flat. This one is still a puzzle.

BTW, I've driven about 800,000 miles in diesel MB's and about 350,000 miles or so in gas MB's. All the diesel noise, efficiency and all that aside, only sitting in the drivers seat, I'll take any of those gas cars any day over the diesel cars, but that's just me.
