Macbook Pro turned off after pluggin' an usb wire

mine suddenly started working again. I tried charging it for a day when the charging light was very dim, then i just left it unplugged for a few days, because i gave up. battery probably discharged itself or something. Because when i took it in, they just plugged it in and it worked. I was so relieved lol.

You can try and find a new motherboard on ebay or some other site and replace it yourself? it may be cheaper.

how did you guys turned it on again?? thank you.. cause it happens to me, but with no particular reason, it just happens (no light in the charger not even in the led indicator, doesnt respond to the power button), and in a few days it just responds again... can anyone help me solve this?

It happened also to me:

MB Pro 13.3", I7, 2.7/2x2GB/500GB HD,

bought on the 11th march 2011 in NYC/5th av store.

I've connected a USB pen, 2GB, working in others mac and PC, and just in the moment I've plugged it, the MBPro turned off, no sign from battery led, when I connect the charger it doesn't show the light, or it shows an intermittent green light, very low power.

This just happened to me. I didn't realize it was the USB cable that did it (third party lightning cable). I then swapped my hdd and put into a different macbook pro we had. Worked fine, until I went to charge my phone. Then same thing, but I didn't even have the phone plugged in. As soon as I plugged in the usb cable, macbook pro turned off, and then the led light on charger got weaker and weaker. Then the LED on charger wouldn't show, and battery LEDs do nothing. Same thing as everyone else. Pulled ram, reset SMC, and am just about to pull the battery to see if that helps. Can't believe this "feature" got me twice in the same day on two different laptops.

Yeah, its the cheap wires and if the wire has a short in it, it probably messed up your logicboard. costs around 200-300 to repair from apple. you can try and discharge the battery, but i think that voids the warranty if you still have one.

I have to find my receipt or hope to get a new one from best buy, or ill just have to void my warranty and try discharging the battery

Masakre...worked for me. Even went out to buy a TriWing bit, but you don't need one. Just pop back cover off and disconnect battery from logicboard. Wait about 10 seconds, plug it back in, and it's good to go. Fixed both laptops in a span of 5 minutes! Thanks.

Same thing happenned to me last week. I went to get it fixed, it worked til I plugged by Bamboo usb in again. Now my motherboard is screwed and they must change it for 600,00$... I bought my 15 inch Mac in 2011. Has anyone also got that problem with a computer dated from 2011 ? Cause I don't want to pay that, it's a quater of the price I bought it. However, I can't find anything on Internet that would help me save money...

HELP !

Eroms,

This is a rather old thread - you might get more responses by starting your own.

Do you have the same problem as the original poster? Does your MacBook Pro 'turn off' after plugging in a USB device?

Instead of replying you may want to start your own thread and decribe exactly what problems you're having.

NO - DO NOT let the battery completely discharge.

I don't know why, but we get dozens of complaints from folks who have had their MacBook Pros 'die' after having plugged in an iPhone to charge/transfer files. If an SMC reset won't do the trick the only thing that I can suggest is taking the machine to your local Apple Store or an AASP and have them fix the problem. And when they do, please let us know specifically what they did... I read of the problem often but, if an SMC does not work, very few solutions.

You might also want to post in the iPhone forum to see if any of the pros there know of a resurrection trick.

What worked for me was disconnecting battery for about 5 seconds, then connecting it again. Make sure when you do this you have the power adapter disconnected as well.

If you don't want to/can't do this, just let it discharge completely. Either way it will work.

Hey I also had the same problem with my mac book pro late 2011 about a year ago. I was using a charger I bought at a gas station because the other one broke. Plugged it in and dead. Totally dead no lights no nothing. So I called tech support and talk with about 10 different helpers, even one or two "experts" no one could tell anything more than the mother board was fried. I stayed up all night researching and i finally came to a conclusion of opening up the back of my mac book pro and taking the battery out and putting it back in. As simple as that. I have never personaly seen this problem after it happened to me but it's worth a try. I hope this saves some purple a lot of time and money.

Even though I am sure that you solved the problem since it was 5 years ago, do this:

(1) pop out all of the screws on the bottom of the computer,

(2) make sure to discharge any static electricity,

(3) disconnect the internal battery cable and wait for 10 seconds,

(4) reconnect and press power button with bottom cover still removed,

(5) if works, re-attach bottom cover and re-insert screws

If not, let computer battery completely die, then attempt recharging.

Once computer is working again, do a PRAM reset and refrain from using the USB that caused the issue.

My daughter tried to plug her lightning cable from her ipod into a USB slot or other slot on my 2010 laptop, trying to hook up speakers, She's 12 and it was a random mistake. Same thing, computer cut out, would not start, no lights nothing. Took out battery, held restart for 4 minutes, and left for 20 minutes. Put it back together and worked. So, if your computer shorts out from electrical charge or other, try it.

I've had the exact same thing happen to me before. After hours of googling, I found the best solution for those who can't unscrew the back and take out the battery, is to just leave it how it is and the battery will drain by itself. Depending on how charged your laptop is, could take a few hours to a few days.

Hope this helps!!!
