Hi 

While using the laptop in office, every line or so that I type, my thumbs touch the touchpad and disorient the cursor, and I end up typing on the wrong line. I want to either:

1. Disable the touchpad automatically whenever the system detects an external pointing device like a mouse ,Or

2. Disable the touchpad entirely (Enable it when required)

Unfortunately this particular laptop doesn't seem to have a touchpad disable button. How do I accomplish one of the above?
