The problems affected 15in and 17in MacBook Pros from 2011 and 15in Retina MacBook Pros produced from 2012 to early 2013.Ģ011 MacBook Pro had complained about video issues for years before Apple addressed the issue with a recall. MacBook Pro video issuesĪ “small percentage” of MacBook Pros sold between February 2011 and December 2013 experienced issues with distorted video and out-of-the-blue system restarts. If your MacBook Pro has been damaged by the crackles and pops then you should be able to make a warranty claim with Apple. Notably, users affected by the issue report that simply turning the volume control down has no effect the loud crackling and pops continue. The crackling/pops will not be heard in the headphones. I found these instructions INVALUABLE in replacing my old logic board.You could also ensure that headphones are attached via the 3.5mm audio jack before using Boot Camp to boot into Windows, as this will avoid the MacBook Pro’s speakers being used. Indeed that was exactly the case, and logic board replacement did fix the issue. I ordered another new battery, and after draining a second battery without being able to charge, I figured that spark was the sign that I fried something in the logic board. Instead, the computer ran off the 30% charge that new batteries are shipped with. Further, the wall charger would not recharge the new battery.
New battery installed, but the OS didn't recognize the new battery - black "X" over the battery indicator. DON'T DO THAT! I saw the tiniest of sparks around pins 4-5-6 on the 9 pin battery connector. However, when removing the damaged, swollen battery, I used the end of a flat head screw driver to pry up the battery connection. I've replaced batteries before, so I knew that it was definitely a swollen battery.
