What sort of mouse?

[Ferg]

Heres a quick one that someone is sure to know. I'm using a borrowed laptop - an IBM Thinkpad, not more than a year or two old. First serious time with a lappy.

I want to plug a mouse in, but the mouse socket at the back won't take a PS2 mouse. Besides a serial mouse, what is supposed to go in there? It has a rectangular hole at the bottom of the socket and accepts four pins.

Thanks.

The easy way is to just use a USB mouse.

That four pin port sounds like a firewire port.

Lots of new laptops do not provide the older PS/2 port anymore, so you would just use a USB port if you wished to connect an external mouse or keyboard.
