Hello, this computer is a VGN-TXN15P which originally ran on XP but now runs on Windows 7 Ultimate. I need an ALPS download so I can have scrolling and turn off the tapping.
HERE is a link for the touchpad drivers on that computer for Windows Vista. Unfortunately Sony did not release Win7 drivers for that computer due to sheer age of the machine. Try the Vista drivers which being what it is should work fine.
