@gary64521 - Carefully disconnect the battery following this guide Remplacement de la batterie du MacBook Pro 15"Retina mi-2015 also inspect the battery to see if it’s puffy, if it is you may need to replace it. But for now with nothing connected and the battery not connected press and hold the power button for a goo 15secs that will de-energies the logic board. Now just plug in your MagSafe charger. The system should spontaneously restart, let it fully boot up and do a clean shutdown. Now reconnect the battery and try to restart the system again, did it startup this time?


If you’re running I would encourage you to install this gem if an app CoconutBattery ost a snapshot of the Apps main window here for us to see.

@gary64521 - No reaction is not good😫

This sounds like a logic board issue then. Time to find someone with the tools and skills to debug the logic board.
