i have a creaky hinge on my 3 month old mbp

the title says it all but after searching a lot, there has been no answers. every time i open ore close my 15inch mbp, it has this creaky sound in the hinge. this is really annoying because its every time that i open or close it it does this. does anybody have any suggestions on how to fix this? i really dont want to go to the apple store because i just yesterday had to beg my mom to drive me 30 minutes to get my iphone replaced. this has been happening for a little over 2 weeks. any help would be appreciated.

That is a real creak..... unfortunately, unless you want start with trying things like graphite powder, silicone or dry lubricant spray, Apple is the way to go.
