The touchpad and mouse buttons on laptop computers provide a built-in method for computer navigation when an external mouse is not available. The touchpad and mouse buttons are often found directly below the keyboard, which causes problems for some laptop users. When typing, some users inadvertently tap the touchpad or mouse buttons, causing the cursor to relocate to a different part of the screen. This causes error in the documents the user is typing. To prevent this from happening, you can disable the touchpad and mouse buttons.
Click the "Start" button and open "Control Panel." A list of options will appear in the window.
