How to deactivate the touchpad on a Sony Vaio laptop?

Not permanently, as well as but carrying to reboot a laptop. Just a discerning approach to spin a touchpad upon as well as off. Is there any set of keys by-pass or freeware to do that? The indication is Vaio SZ3.

Suggestions:


1. in the keyboard settings (will need to restart for it to work)

2. im not sure of the model, but on the models out in the last few years, there’s usually a button next to the touchpad or an icon on the touchpad that will lock it.

3. try a hammer, that should stop it workin
