Notebook Hardware and Upgrade Questions

I didn't really notice this problem until a few months after having this computer. I have been making bi-weekly payments on this wonderful laptop since fall of last year through a local Circuit World. I soon started to notice that even if I opened the laptop slowly or gently, there was this awful cracking noise coming from the computer. I had gotten used to it and assumed it was a minor thing, as I have experienced with other laptops in the past. It wasn't until I had run my hand over the left corner of the laptop that I noticed that the bottom cover had been starting to "pop out" or at least not connect itself correctly to the top cover as the right side did. 

I have never once damaged this laptop via tossing, dropping or rough handling. This computer is very expensive and takes a lot from my budget, so I have made sure to take the most absolute delicate care of this computer, including handling and virus protection. 

Unfortunately, with this computer now being excessively harder to open than it should, and the damage that I'm afraid this left hinge is causing, it has become more than just a "little" problem to me, and I fear that it will only worsen over time. I've noticed that in another forum, a customer had their HP ENVY replaced, but I'm wary that I cannot recieve the same treatment because of my purchase throught Circuit World. 
I will talk to the employees at Circuit World about getting it fixed or getting a replacement if that applies to me, but for now I'm looking to see if there is a simple, easy fix to this problem, at least one that could save time or money because the left hinge problem seems relatively easy to fix, I'm just not going to take chances with damages to my own computer. This also seems to be a problem that isn't solely happening to me, but very many other HP ENVY 17 owners. Thank you!
