solution for "plink" that worked for me
Hello friends -- I am a first time poster, so forgive me in advance if I mess up any rules of etiquette. I am posting because this "plink" issue was giving me a problem, and forums like these really helped me figure out what was going on. I hope that I can share something that will help.
So anyway, based on the fact that if i put pressure on certain parts of mbp's bottom I would hear this plink with greater frequency, and from what others have said on other forums

I figured that the best hypothesis was that something was scratching the inside of the bottom cover. I took the screws out (if you do this, try to arrange the order of the screws in the way you took them out...some screws are different). I removed the cover, and noticed that there are tiny pegs. they are springs so that the cover doesn't damage the internal hardware. These pegs make contact with the inside of the mbp's bottom -- there is even some plastic covering on the inside of the mbp's bottom cover so to avoid metal-to-metal contact. It seems that Apple may have screwed on the bottoms so tight that these pegs have worn away this plastic and thus introducing metal-to-metal contact (hence the plink, especially with certain pressure).
As many others have mentioned -- the sound may go away simply by putting the cover back on. The reason is because we may not put the screws back on as tightly as Apple did. This worked for me -- I haven't heard the plink since.
Sorry for the long post, but this method worked for alleviating my "plink" and I thought I'd share some reasoning on why it may work for you. Good luck!
