So I messed up! Had a USB expansion hub and thought it would charge a phone if I plugged the power cord into it. I grabbed the wrong cord. It fit perfectly, but it put 12v into the USB hub that should only have had 5v and instantly killed the computer! Anyone else ever do this or know what I fried and need to replace. Model A1419.

I think your best direction here is just going to an Apple Store with your system and letting them fix it. Clearly your logic board is messed up and you could have also damaged the power supply. I would ask for the flat rate repair and pray they don’t need to replace to many parts. You might want to get a cheap Brother P-Touch cable printer and cable both you power bricks and devices so you don’t mess up again. Don’t feel back I’ve blown a few things not realizing the same thing.
