The usb port that I plug things such as my printer/mouse into is really touchy. I have 2 ports so I am using the other one right now, but it seems like the other one doesn't work and I have to jiggle my cord a certain way to even get it to connect and then it doesn't remain connected. I have no idea how to go about this but is it possbile to go buy another port and replace it or do I have to have a professional look into it? I have a Dell Inspiron 8500 laptop and have had it for about 3 1/2 years now. Thanks!
