I just received my new mbp and went to a company called Elan computers to have them install a ocz vertex SSD(my local apple store wouldn't install it). It all seemed fine before I took it in (stock 320 GB 7200 RPM) but now there is a buzzing noise coming from the left side after they installed it. The noise changes frequencies if I push a little on the left side. Is this normal? What should I do?
