The good news is that manufacturers of modern laptops have tried to address the issue up front. The easiest way to disable a touchpad depends on the hardware. You don’t need to put up with that, however-here’s how to turn it off. When you’re typing on a laptop’s keyboard, it’s common to brush against the touchpad and inadvertently send the cursor flying across the screen. But whether you love touchpads or just tolerate them, they still get in the way sometimes. Even when a mouse or another pointing device is available, some users prefer the feel of a touchpad above anything else. Since touchpads are built into a laptop, they work well when you don’t want to carry around another pointing device.
The touchpad has been the standard laptop pointing device for years.
