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.
