Macbook pro early 2011 model motherboard short circuted on connecting data cable to USB port
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.
