    Noticed today during a weekly "scratch inspection" that my bottom case seems to make a tapping sound near the middle when a little bit of pressure is applied. Is this cause for concern?

    Umm, is this post necessary?

    Edit: I know from previous experience that there are two clips that attach the bottom case. These two clips are positioned between the logic board and the battery. Could it be that the bottom case clips are not secured into the slots?

    have you had it opened before? - if yes just push harder, if no try it anyway.

    really there are a few snaps on the inside and they may not be pushed in all the way, they will make a click if you push them in, but you have to push kind of hard.

    Yea, I opened it up a few weeks ago. I did notice that it was rather difficult to separate the two halves even with all 10 screws removed. Sure enough, it was those clips holding it on. However, when I reattached the bottom case, I never really heard these clips "re-engage" with a noticeable "clip"

    I just upgraded the RAM in my 15" MBP yesterday. It does take some pressure to re-engage the clips. The pressure should be applied directly on the clip locations. You'll feel and hear it when the clips snap in.

    Between the clips there's a strip of sharp grounding fingers that makes a radio frequency ground connection between the bottom plate and the logic board, and requires a firm connection. If the clips aren't engaged, the fingers will scrape or tap against the bottom cover when it flexes.

    Here is a thread on what I think is also what you are talking about PoPPIng

    Apple put on a new screen for me today, and the "popping" is gone. I noticed it as well after upgrading the RAM and HD.
