    Dear folks,

    Recently i experienced some complicated issues with my Macbook pro 13" late "11.

    Problems started with a complete dead laptop. Not willing to start-up. Performed the official advised steps to check what kind of problem it could be. Nothing worked, complete dead laptop.

    However, after several days i tried again and the laptop gave a different respons when starting up. Instead of staying completly dead it gave me a 3-beep sound at start-up which indicates RAM issues if im correct. I swapped the RAM's and tried them one by one. Eventually even tried identical ones from another mac pro but problem stayed the same.

    To make things more complicated a few days later when trying to reboot the laptop it worked fine for half a day untill the problem returned. At this moment 50% of the time it is not booting and giving me the 3-beep sound on a black screen. Th other 50% of th time it gives me a start up chime and it looks to working fine for some minutes! Varying after 10sec. - 2min. it will show strange patterns in the screen and eventually it will reboot.

    I start to worry it might be a faulty logic board?
    Advise please!

    If you have a dGPU the it could be the graphics card failing. Apple has an extended repair program:

    The repair will require Apple to replace the logic board. Contact an Apple store to schedule testing if you have a dGPU.

    Now that your edit added in 13" it is obvious that my first post (#2) doesn't apply. Nevermind.
