a couple of times while using my laptop with the screen open, ive had to lift it up while holding onto the bottom of the computer. in doing so i noticed a slight metallic tinking sound . at first i ignored it but i started noticing it everytime i would pick up the laptop. ive localized the problem and notice that it only makes this noise when im applying pressure towards the middle of the laptop. ive read many people having this problem online, but most had to do with the 2010 macbook pros where they were using some spinning hard drive but the mb pro 2012 retinas are supposed to be SSD right? so i shouldnt be having this problem can those of you who own mb pro retinas hold your laptop and put pressure on the bottom of the laptop? just gently push around toward the middle area and if you dont get a "tinking" sound right away just start gently pushing all around the general area i really want apple to replace my mb pro im still within my warranty but im outside of the 14 day return policy.
