    I need your help and expert suggestion. I have a Retina Mid-2015 15" - MacBookPro11,4 (IG) - A1398. It was working last 2 years without any issue. Suddenly 2 days before doesn’t turn it on. The mega safe adapter light stays on Green.


    I have made some attempt

    1. Reset the System Management Controller (SMC) with this method Shift+Control+Option keys and the Power button at the same time. Release all keys and the power button at the same time the MagSafe adapter stay as green NO flash.

    2. Resetting PRAM
    Command, Option, P, and R keys at the same time. No sound hear the startup. MagSafe adapter stay as green.

    3. I removed the battery connector from the Logical board and after 5 minute re plugged again and tried to open no success megasafe adapter stay Green.

    4. 2nd attempt removed the battery connector from the Logical board and connect mega safe adapter won’t boot but the mega safe adapter stay Orange color.

    Please give me your suggestion what exactly the fault. Is it the battery or Logical Board damage or MagSafe2 DC Jack Power Board.

    Try to hold down the power button for exactly 10 seconds and while still holding down the power button, plug the power cable in, and keep holding the button until it comes on.

    Nope, this is a board by and for users of apple hardware and software, technicians who repair apple hardware on a daily basis generally don't use apple hardware themselves (insert your own conclusion here why they don't want to invest in apple stuff) and thus are not on this forum.
