and the same shit is happening Bought a MBP in July, and in August, a static hum appeared from the right speaker. Called Apple, sent it in and the service record stated that they replaced the right speaker cable and speaker assembly. The day I received it, the same hum was present, but I needed my computer and couldn't be without it. I finally took it to the apple store in Vegas, and I couldn't replicate the hum, but sent it in anyways and when I got it back, they replaced the same thing as before...and guess what? THE FUCKING HUM IS BACK What should I do when I call again? Ask for a replacement?
