    Macbook Pro 13" A1278 820-2936-B three beeps

    Hi,

    When i turn on the Macbook, it sounds 3 quick beeps each 3 seconds.
    I've already swapped memories each slot; tested with new memories; checked screws on slot; checked pads soldered on Logic Board and still the same problem.

    I read it also could be faulty Bios, or faulty graphic memorie? Am i right?


    What else can i check?

              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...

              MacBook A1278 (3115) No PPBUS_G3H Issue
              by pcbmaniac
              Subject: Help Needed: MacBook A1278 (3115) No PPBUS_G3H Issue

              Hello everyone,

              I'm working on a MacBook A1278 with the 3115 logic board and facing an issue with no PPBUS_G3H voltage. Here's what I've checked so far:
              1. U7000 Measurements:
                • Pin 3 has 0V, even though R7012 shows 16.5V from PPDCIN_S5_CHGR.
              2. Resistors:
                • I measured R7010 and R7011 with one leg disconnected, and both tested OK.

              Based on these findings, I believe U7000 needs to be replaced. However, I have a related question:
              • If I also decide to replace the SMC, do I need to order it pre-programmed,
              ...

              MacBook Pro 2018 with Activation Lock
              by envym
              Hi everyone!

              I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

              I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...
