Hi I got my new Macbook pro 15" (Mid 2015) last week and have been enjoying it completly without any problems so far! But yesterday i was carrying the laptop in my sleeve (Inside my bag withnothing else in it, so no weight on the laptop) and i heard a "snap" sound which i didnt think more about. But today when i was going to lift it, i noticed that the bottom right part of the case is flexing up and down about 1-2mm, its quite hard to see it, but it feels like the aluminium bottom part is flexing so it touches the hardware inside and makes a very weak "dot" noise. The left side of the bottom is completly solid / rigid and has no flexing, and its only flexing around the area that i've marked with a coin (see picture). Is this something that is normal and i didnt notice when i got the laptop? Or should i head to a apple service center and see if something is wrong with it? It's barely used and only 5 days old since i got it.
