Mouse Connection

Dear Computer Lady,

I have a Dell computer, and have 4 usb ports in the back and two in the front. I bought a wireless mouse that has a round end and my ports are the rectangle size. I find that the mouse selections do not inform you of this before purchase. How can I determine that I am purchasing the correct one.


Dear Frances,

On modern computers, there are usually two different ways to connect your mouse. One is the round, PS/2 port, and the other is a rectangle USB port. I have noticed that many Dell computers have dropped the PS/2 connection entirely and depend entirely on USB connections for their mouse and keyboards.

When you go to purchase a mouse, wireless or not, the packaging will say that the mouse is either PS/2 or, USB. Often, the mouse will have an adapter and say both USB and PS/2. As long as you make sure the mouse says USB somewhere on the packaging, you will be assured that it will work with your computer.

    Hi Frances,

    All you have to do to make your mouse work is buy an adaptor that has a ps/2 port on one end and a USB connector on the other end. They only cost a couple of bucks. If I could send you an attachment, I would send a picture of one.
