Hello,
After I updated my my computer, the touchpad doesn't work. Formerly I am using Wins XP and now had upgraded to Vista. The 'Roll back driver' function do not active. Where can I have the earlier driver for the touch pad.
This link contains all of the Vista drivers for your computer. Install the appropriate driver and you are set.
