Ok, I bought a MBA on 10th of January , and i have issues with the left speaker, it makes some buzzing noise even when I'm at 50% of volume. Also the magnets that keep my lid closed , the left one is weaker than the other. I am covered by Apple's 1 Year Limited Warranty , and I'm going to Torino tomorrow and there's an Apple Store (Le Gru). What can I expect and what should i do ,will i have a reparation ,a replacement ?? Any advice what to do ?? Thanks
