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?
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.
