Acer's Aspire 5920 is a laptop that runs Windows software. Like other laptops, the Aspire 5920 has a built-in keyboard. It also has USB ports that make it possible to use an external keyboard in case the built-in keyboard is malfunctioning, or in case the user simply wants to type on an external keyboard. If you use an external keyboard, or if your Aspire 5920's keyboard is malfunctioning, consider uninstalling the keyboard driver. This will disable the laptop's built-in keyboard from use.
