I have an IBM 365x Laptop computer.

When I plug in my external PS/2 mouse, it does not work. The TrackPoint mouse on the keyboard still works, but the external mouse does not.

The Control Panel and Device Manager only show one mouse installed: PS/2 Compatible Mouse Port.

I can't find anywhere how to switch from using the on-board mouse to my external mouse.
