it's a 9 pin plug in in back of laptop....have an adaptor plugged into that then plugged my mouse into it (round connector).
but windows does not pick up external mouse...have gone to control panel etc., can't figure out how to get it to recognize the external mouse instead of the little one in the middle of the keyboard...rather use external. I guess it doesn't really matter, but setting it up for my daughter to use for her school work. Going to hook it up through router so both mine and the laptop can run off LAN/CABLE.
