How can I disable the touch pad when an external mouse is attached?

Hello and welcome to the Windows 7 Forums.
The easiest way to do so would probably be to press the function key (Fn) and Either F5,6,7 or 8 (So Fn+F7 for example)
If that doesn't work, please post some system specs so we know exactly what computer model you have,
Cheers!
