Retina Mid-2015 15" - MacBookPro11,4 (IG) - A1398 won't turn on -
I need help and your expert help. I have a Retina Mid-2015 15" - MacBookPro11,4 (IG) - A1398.
It was working great for the last 2 years without any issues. Suddenly 2 days ago it won't turn it on. The MagSafe adapter light stays Green.
I have made some attempts:
- Reset the System Management Controller (SMC) - Using 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.
- Resetting PRAM - Using Command, Option, P, and R keys at the same time. No sound hear the startup. MagSafe adapter stays Green.
- I removed the battery connector from the Logical board and after 5 minute re plugged again and tried to open no success MagSafe adapter still stays Green.
- 2nd attempt removed the battery connector from the logic board and connected MagSafe adapter it still won’t boot but the MagSafe adapter stays Orange color!
Please give me your suggestion what exactly the fault.
Is it the battery or logic board damage or MagSafe DC-In board?
