Macbook pro early 2011 model motherboard short circuted on connecting data cable to USB port I have macbook pro early 2011 MC700 model. Few days back I was using it on battery and connected my samsung phone data cable to USB port and when I was about to connect other end of cable to my phone, macbook crashed. I took it to service centre and after few days technician told me macbook motherboard has short circuted and it need to be replaced. My macbook is just 3 month old and warranty has saved me from the cost of repair. I want to know what exactly is reason of short circuit. Is it fault in that model or this kind of short circuit of motherboard on connecting data cable is a common phenomenon. Now in future I will think twice before connecting my USB cable or pendrive to USB port of macbook. What can be exact reason of shortcircuit of motherboard. Thanks in advance.

I youtubed/googled the issue and all I needed to do was remove the battery plug on the logicboard and I guess the system resets and it worked again. MacBook Pro alive.



How did I learn this? This happened to me at well. I had my MacBook Pro 17' connected to my Thunderbolt Display and when decided to charge my ipad using the USB and when I connected the iPad, everything shutdown. I couldn't even power it back on. Took it to apple store and they told me 500 bucks. WHAT$$$ They don't even diagnose the problem.
