    Macbook Pro A1278 Motherboard Damage

    Hi,
    I have a Macbook Pro 13" A1278 early 2011 i5 with 2 dead USB ports.
    (Motherboard model: 820-2936-B)

    I looked inside and noticed what seems to be the problem.
    An SMD component on the board is missing and I can't tell what type of part it is because it is gone. There is a "brother" part beside it (pictured below) that looks VERY similar, in size, form, and relative position.

    First pic shows what i think is equivalent brother part, second shows the 4 points where the old one was, third shows bother parts and their seemingly equivalent nature.

    Can anyone identify this part, someone suggested recently that it was a "choke" but didn't elaborate on the make and model of the part.

    Thanks,
    Brian

    It's a filter/inductor, and yes, it needs to be the same, good if you can just find a donor board (you can get them for about $20 on AliExpress.

      Looking for 13" Macbook Pro A1278 mid 2012 820-2565-A Schematics and Board View
      by Rezendes
      Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.

      I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.

      The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There...

      A1466 Macbook Air (Liquid damage repair)
      by mon2
      Hi. Recently serviced a damaged A1466 Macbook Air. Thought to post the issues and resolution for each.

      Macbook AIR Model A1466 Diagnostic 09-01-2021

      Issue: Liquid damaged (beer spill) Macbook AIR will not power up.


      Problems & Resolutions

      1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....

      MacBook Pro M4 16" A3403 on the table with water damage
      by TimSinger
      Hi guys,
      I have a MacBook Pro M4 16" A3403 on the table with water damage. I allready found the problem within a bad cap. As far as my researh went, I couldn't find the schematics and boardview for this MacBook model. They seem not to be released now. So my question is if anybody has a working A3403 on the table and could tell me, which specification this capasator has?
      I attached a photo of the missing cap. It's on the bottom side of the logicbard.

      I am very thankful for your replys.
      Thanks in advanced and best regards from Hamburg Germany...
