HP and Compaq Presario laptop computers are made by the same company, so the hardware on certain models of each brand might be nearly identical. Many newer laptops, for example, use identical technology to control the touchpad, which in turn controls your mouse cursor. If you want to disable this touchpad use the software already installed on your PC.
Click "Control Panel."
Click the "Device Settings" tab.
Click on the listing for the HP touchpad to highlight it. Click the "Disable" button to disable the HP touchpad on your Compaq Presario laptop computer.
