Why won't my LG Optimus link with my lenovo laptop?

My laptop won't recognize my cell phone. I will charge, but it will not recognize it in any other way. I'm trying to transfer pictures from phone to computer and vice versa, as well as song. I have never been able to with this lap top. Only my old one. I checked the box in applications saying debugging, but it still doesn't work. I have tried different cords. Does not work. I have also tried all my USB ports. Still doe snot work. Lenovo tech support said that there's not driver needed to be updated, and my cell phone tech support said there's nothing wrong with the phone. Who can i depend on if both sides can't help me?
