What is that SMD part next to fan connector?

    Which mini is that Adam? What happened to the SMD part? Did someone attempt a repair to the connector?

    If you could take a sharper picture of the area it might help. More light and/or a different camera can help image resolution and contrast.

    hi Celerondon,

    It's 2011 mini (mini 5,1).
    I was trying to replace HDD and when disconnecting the fan connector - I dropped my tool on the board and the thing came off (with solder points unfortunately...). I couldn't find it (must have bounced and landed on the floor I guess).
    Anyway - end result is that I don't know what it was (I'm guessing a resistor) and I don't really have anything to solder it back to. There's one point I could use hidden behind the fan socket (that I can track) but I don't know how it was connected to the other side (again - guess - probably to the capacitor right next to it but no idea which way)...
    Anyway - if somebody could at last measure what resistor is that...?

    Can't take better picture - the only camera I have is my phone.. And it's not the best one as you can see...

    To measure the capacitance / resistance / whatever on a component when it's on a circuit board, you're likely to get an inaccurate reading unless you disconnect at least one end of the component because of the influence of the components connected to it. I doubt anybody would be willing to do that.

    Aha! So you do not have the part. Believe it or not, this could be good news. :rolleyes:

    If you never reassembled that job we may be on the verge of the acid test for your mini. First though, I suggest that you visit iFixit to research the appearance of your missing component. https://www.ifixit.com/Teardown/Mac+Mini+Mid+2011+Teardown/6131

    Do you see it in this image? :cool:
