Someone kicked my computer while the headphones were in the jack, damaging my expensive headphone. It also seemingly caused the laptop to believe that there are always headphones in the jack. Also, it sounds strange when I listen with my headphones, unless I fiddle with the connector. What should I do? Do you think I need a new jack? What is this called? How much do you think it would cost? Should I just live with without speakers? It's a Lenovo win 7 i5. Less than a year old.
Check with a repair shop, prices can vary.
