OK I finally took the time to figure out how to disable touchpad mouse so it doesn't take two hours to make a post !
I wanted to share this with everyone !!!
Touchpads can get very annoying at times, especially when you are writing a long mail or a piece for your blog. Most of the laptops around have a special button to turn the touchpad on\off, like my old Toshiba had a Fn+F9 button to get rid of it. In Sony Vaio there is no such special button to take care of the same (and I wonder why?) So, how do I get to disable the touchpad when I don't need it?
Here's the key:
Go to C:\Program Files\Sony\Setting Utility Series
Untick the "Enable" checkbox and voila!
This would disable the touchpad. You could create a shortcut to the file above for quick, easy access!
To enable the touchpad you need to run the same executable and tick the "Enable" checkbox. You need to have an external mouse to move around, and if you are a GNU-Linux freak, I guess you can make you way around without the mouse.
