I was in a Zoom conversation when my MacBook suddenly turned off. The light for the battery kept being Green. I have tried diagnostic the issue myself and this is the behavior: When power cable is plugged in the light is greenWhen I do the shift+cmd+opt+on button light does not flickerI have opened the back and disconnected the battery:With the battery disconnected and the cable connected the light is AmberIf I do the long shift+cmd+alt+power reset at release the light flashes green and then it comes back to Amber Still it does not seem to turn on. The laptop has not suffered any water damage. The battery looks fine on the inside and there is no sign of damage. Is this something you can help me with?
Lets give this a try, Disconnect the battery again, but this time don’t connect the MagSafe charger, press the power button for a good 15 secs to fully discharge the logic board now plug in the MagSafe without the battery connected, your system should spontaneously start did it?
