Hi all. I purchased a 15.4 in Macbook Pro two weeks ago and I carry it in a Swiss Gear SYNERGY Computer Backpack, but I noticed that my notebook lid isn't closing perfectly parallel with the hand rest base, i.e. the top corners of my lid are 1mm or 2mm apart from it. I realized that when placing the notebook in my backpack, resting on any of the ports side, it causes the other side to create a (tiny) gap between the lid and the base (especially in the top corner). So my questions are: Is this normal, or is it related to the position I put the notebook in my backpack? Would it be better if I got a carrying case that positions the notebook horizontally (like Vyper exo) instead of vertically (as in my backback)? Thanks in advance!
