I got the base Macbook pro 15 inch recently and from my own point of prospective I have been taking care of my Macbook pro very well. I mean who wouldn't if you bought something close to 2k right? Anyways, when I went about finishing my business with the MBP, I gently closed down the lid and right when it hit at about 40 or 50 degree angle there was a slight creaking sound. I mean its like creaakkkk..... and then it closed. There doesn't seem to be any creaking when I open the lid though. So it seems kinda strange that there would be a creaking sound when the macbook pro was bought recently at an Apple Store. I still have a one year warranty if anything goes wrong but I am just wondering if exterior sounds pertaining to the machine is normal?
