    Hi
    Today I opened my macbook pro late 2011 17", and when I was abou to upgrade my ram I saw a loose part laying just beside the ram slots (picture attached).
    I saw that on the mainboard there is some more of these things but I couldn't find the place where it was attached.
    Any idea what is this part and what is it responsible for? Should I worry?
    For now I checked the computer withe the new ram and everything seems fine.
    Can I repair it somehow? although I think that it was soldered to the board.
    pls help :)))
    thx in advance :)

    You are lucky it didn't short circuit something.
    Don't know what it actually is but looks like it's a cap for something, sometimes you see caps on bolts for safety, or not to get damage if there are cables nearby.
    Tried to do a reverse image lookup but the picture isn't good enough for that, to little contrast.

    I think it's one of this kind (see picture attached) there are several places on the board where you can find them, but I was looking for a missing one and could't find it maybe it came of while I was opening the case, or maybe it was done in the factory. I wonder what it does?

    I think I found out, but let me first ask on which side the "hoods" are?

    I am not english so forgive me if the word is wrong.

    Think it's a bushing with thread in it, the one where the bolt/screw goes in.
    And, if that is true I would open up the MBP again, there could still be a small bolt inside.

    Is there thread inside, it is probably very small, not bigger than 5mm (1/5"), is this true?

    Look at the attachment, it's where the heatpipe is attached to.

    but the bottom of it is completly flat, as if it was sticked to something

    I will do a better picture in a sec

    I think you're correct here. Those are just spring loaded pins that contact the case. If I had to guess, I'd say they're all connected to ground. There are probably half a dozen more, so if you're not having problems everything is fine.

    It's hard to tell from the first picture alone since there isn't anything there as a size reference.

    new pics of the piece, I also thought that it could be a stopper for the case bottom, but I want to be sure :)

    unfortunately the pictures out of focus :/

    I have issues with my internet here, slow like hell, cell tower maintenance was done but after it it's worse, sorry if I can not reply or late.

    Might have the wrong image posted from a different MBP, does not look similar.

    Really have to be a close-up to see it well, they seem to be tiny, if it's any smaller than lets say 3-5 mm my explanation might be wrong.

    Edit: just looked at the last images you gave, it seems like it was soldered to the logic board and I think you and the other poster are right, a stopper and/or a pin to make contact to the housing.

    Edit Again: what is the height of the pin.
    And, if the above is the case then there is little to worry about.
