Check your laptop’s documentation for specific methods. For example, on some Dell laptops, the setting to disable the touchpad is located in the Dell's support software. The PC might also offer a keyboard shortcut (such as pressing Fn and F7 simultaneously) to disable the touchpad, or perhaps pressing a certain area of the touchpad itself will turn it off. The F5 key has a symbol on it that resembles the shape of the touch pad.

On my Toshiba FN plus F5 controls the switching of the screens (internal, external and dual). On some notebooks, you’ll find a physical switch to disable and enable the touchpad look around the laptop’s edge for it. re: trying to disable the internal touchpad. 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.
