This is sounding awfully similar to what happened here: I changed my A1398 battery last week, with the iFixit kit Everything went well then 3 days later the computer suddenly shuts down and stays dead. The battery is charging, a SMC reset shows the LED changing colour, it just won’t turn on. Disconnecting the battery doesn’t help. I have to wait a few hours before being able to power it on again, only to see it die again after a couple minutes. Would that be the battery that killed the logic board? I’m using an original magsafe charger. Edit: I managed to boot it long enough to run CoconutBattery, before it died again. Actually a Simplo battery
I don’t see a battery issue here, so that’s good! As you didn’t have the system under charge I can’t tell you what’s happening with the charging logic. Allow the systems charge to drop below 60% and then plug in your charger give it a few minutes to start the charging cycle and take a second snapshot. As to the sudden shutdown, You’ll need to look deeper using the onboard diagnostics for starters: Restart the system and pressing the D key to enter. Did you get any errors? Reference: Mac startup key combinations
