Macbook Pro 2012 13" Screen/Hinge pops when closing
Title basically describes what my problem has been. Sometime when I close the laptop, a loud popping noise is heard coming from either the screen or the hinge (I believe it is the hinge). Other times it is just a faint creaking noise. I understand that this is a common problem among Macbooks that is caused by a small group of wires popping back into place, but I was just wondering if I needed to have it seem about and if it can cause future problems. I am still under warranty, so would this be a free fix? I have never dropped the laptop and haven't altered it in any way, so I assume it is a manufacturing problem.
MacBook Pro (13-inch Mid 2012), OS X Mountain Lion (10.8.4)
