That even an apple pad can fail. There is a fine discussion about hardware out there but why must you fix this? It's well inside the warranty.
-> First idea!!! On my laptop I press Fn+f10 to disable the pad. No driver update would ever fix that!!! I don't know which key combo it is on your Tosh but look for that.
-> Second idea. Get a mouse to mouse by for a while.
Have a brand new toshiba satellite, win 7, 95days old and i am out of the country, the touch pad just stopped working. I updated the driver from toshiba.com with no results. Any other suggestions would be helpfull. And all this because I chose this over a mac. ha ha.
