Plugged in USB, MacBook turned off & won't turn back on.

Hi all,

I've got a Retina Macbook (A1502) that seems to be totally dead after plugging in a USB to charge my phone. As soon as I plugged the USB cable into the port, it abruptly shut off and now won't turn on at all. I've tried disconnecting/reconnecting the battery, letting it sit for a week to totally drain the battery, multiple chargers, SMC reset etc.

I took it to the Genius Bar and was told this was a known issue but that it would cost 500$ to replace the logic board as I'm out of warranty. I know this stuff can happen, but as a student with little money I can't afford to fix it right now and I'm a bit peeved that simply plugging in a USB would totally kill the machine (the usb cable wasn't even one of those really cheap ones!). I was hopeful that it was a minor issue after reading about multiple people with similar issues that were resolved after disconnecting/reconnecting the battery but I don't seem to be one of the lucky ones. I had a glimmer of hope after the orange light on the charger came on whereas initially there was no light, but still no boot up. Anyways I'd like to ask if there's anything else I could try or if my only option is a logic board replacement. Thanks for your help.

First try an SMC reset. Here's how:

This failing, and all else that may be recommended, and you do find that it needs a logic board, go for a "Flat Rate Repair". This costs about $357.00 directly from Apple. They FedEx you the box overnight. Total time is four days including shipping. Just call 1-800-MYAPPLE. Just tell them what the machine is doing, don't mention what you did to get it that way.

Hey I had the same problem, I plugged in a usb i don’t normally use on my 2012 macbook pro, and my computer black sreeened and was showing no signs of activity. I took it into apple and they just took out the battery, restarted it and it works fine!

Hey Nathan, Same thing just happened to me. I am so !#^&@@! Did they charge you to take out the battery and put it back in?

Bro, with all types, i just happened to experience the same thing,

Just find any way to replug the battery connector, each mac type has it's own way to replug the battery connector.

Mine is this, https://youtu.be/GgzjJ6A455U

After you replug the battery connector, dont have to replug the battery itself, only the connector. Voila you will see miracle, your mac will start again, there is nothing broken… maybe only an error occured when you plug something to your USB socket

Thank you!! This super easy fix restarted my Macbook Pro, all I had to do was purchase the correct size screwdriver(s) from Wal-mart for $9.00 to unplug and replug the battery connector. Your video probably saved me somewhere between $300 for a repair and $2000 for a replacement. I will NEVER plug anything new into a USB port. As it was, all I plugged in was a little desk top fan that I paid $10 for!!

Thank you so much !! I did the same thing and plugged in a usb charger, which cause my computer to instantly powered off. I tried everything and it wouldn’t turn on. I was so scared I fried it and that it would cost hundreds to repair !! If you have an email I’d love to send you a gift card to Starbucks as a thank you !!

Guess I’m not so lucky… same issue with mine, disconnected and removed the battery, and still nothing but a black screen. Still have a green power signal on my charger however. Weird :(
