    Client's Macbook Pro (Late 2012, A1425) won't boot. Shows the splash screen, shows a status bar that gets to the end but as soon as it gets to the end the computer turns off.

    Running diagnostics returns:
    4mem/9/40000000

    I'm assuming this is an issue with the memory that is soldered to the logic board. Is there anything I can do other than replace the logic board?


    Thanks!

    Yeah it's RAM. Nothing you can do to fix the issue other than replacing the MLB, I'm afraid.

    That is indeed a memory diagnostics issue return code. Might be worth to check the memory

    keysofanxiety: Thank you. I am sure you are right, but I want to get a few more people's opinions before I order a board. I agree with you though.

    Floris: What? What do you mean check the memory?

    Try to see if you can do a memory test? Or ask Apple what your options are about swapping the memory?

    The system's a 13" rMBP unfortunately, can't just swap the memory as it's all soldered. New memory would mean new Logic Board :(

    OP, you could try MemTest x86 to be doubly sure – if you make a bootable USB on FAT32, it does run on Macs when holding 'Alt' on startup.

    I see, yeah, you can ask Apple to confirm the issue and request them the price on having them swapping it.

    My bad, I thought I had explained that. Yea, the memory is soldered to the board. Can't change it out. Testing it at this point is futile since that code I got was from the MBP's onboard diagnostic.

    Actually.. The issue I described where it wouldn't boot was due to an OS corruption, reinstalling OS fixed that. But there was also a motherboard issue with the RAM, and thats what the diagnostics was picking up. After the OS reinstallation, it would kernal panic and reboot.

    So we're good! Now the battery doesn't detect though.
