I have a mid 2015 15" MBPR that I just noticed is bent. At first, I thought it was the lid/screen that was bent, but upon further inspection, it is bent just to the left of the trackpad. It has never been dropped, but I do carry it around in my book bag a lot. It has it's own compartment in my bag and I never have any heavy books or anything in there. Curious how this would happen? The only thing I can think of is if I was wearing it and sat down and leaned against something? Or if I had my book bag leaned against the wall and my infant fell on it? Everything works fine and there are no dings or anything cosmetically, just curious if anyone has had any experience with this. It does not sit even on the table now, the front left side does not touch.
