MacBook Pro suddenly shut off and won't turn on

I realize now that this was probably a dumb thing to do, but I put my wife’s MBP on top of my own MBP. Right when that happened, my MBP suddenly shut down and will no longer start back up. I tried resetting SMC and NVRAM, no luck.

I don’t have the tools to go tinkering inside the laptop, is there anything I can do from the outside to fix this?

Physically stacking your systems shouldn't do anything.

Where they both on and or hot?

Did you plug in the wrong charger thats assuming you have both a 13" & 15" system each uses a different charger?

You are forgetting something here.


They were both on, not sure about hot.

My laptop is a 15", it was plugged in.

My wife's laptop is a 13", it was not plugged in.


Hi did you ever find a way to fix it something like that happened to me and now the laptop is dead


@Fabian Frans - Its best to create your own question giving us your details as Jeremy Ma never came back with any update.


Hi, got an email about this thread, sorry for not updating!

Thankfully this was a company computer and they were able to send it to Apple, RMA it, and have it fixed. Sounded like the logic board was replaced.

The only thing I can think of is a power polarity issue. But that would have required both systems plugged in either to a charger or other AC powered device like a printer or external HD which is directly powered.

Basically, one of the MacBook Pro’s cases is tied to the White (Neutral) side of the outlet and the others case is tied to the Black (Hot) so it fried things!

This can happen when you are plugging two chargers into the same outlet if the charger is not properly designed (knock off charger)

Make sure the chargers are all lined up in the same direction to be safe.
