Hello, I am computer novice and have a question regarding an unusual port on the back of my (old) laptop. It is a female port, small circle, same size as an s-video. It has 2 lines of holes, one line with 4 holes and another with 3 holes. It also has 2 indents for a proper fitting of the cable. I wish I could attach a picture but this dialog box wont let me.
Thank you
