I'm having difficulty disabling the internal pointing device on my laptop computer

To learn how to disable the built-in pointing device, see the manual for your laptop computer.

If you disabled the built-in pointing device, but it was automatically enabled again when you restarted your computer, try the following:

• Manually disable the laptop's built-in pointing device each time you want to use the external pointing device.
• If you have a Microsoft serial-or-PS/2 compatible (serial-mouse-port-compatible) pointing device, use the adapter to connect your pointing device to a serial port on your computer. The label on the bottom of your pointing device indicates the type of pointing device that you have.
