Chosen Solution
I have a beautiful MPB Mid-2012 Retina that has thrown unexpected temper tantrums up until the point where the Mac will not start. It originally shut it down a couple of times when on battery power and plugging it in would calm its nerves and bring the unexpected shutdowns to a stop. However after a week of keeping him on power he quite suddenly stopped booting. When I plug his mag safe cable in, the green light appears to show that the battery is charged, but he no longer responds to my attempted start-ups. He did, at one point, start his fans in the middle of the night, which scared me to death since my desk is in my room, but beyond that he has been mostly-dead. What should my next steps be? Just like the Princess Bride, is my Mac somewhat alive? Was he just trying to breathe out the words true love and am I missing it as to blave? Or have I just beat this analogy dead and there is no hope? The Apple store was absolutely no luck and simply recommended a new computer (Sad, because I think there is a great deal of life still in this mac: There isn’t a single scratch on him). I have repaired motherboards on other’s Macs before, so I am not afraid to make it happen, but I would like to verify that the issue isn’t something smaller before I blow the cash. The iFixit community has never let me down before, so here’s to you guys! Let the advice rain and thanks for your help in advance.
Lets see what a SMC reset does How to reset the System Management Controller (SMC) on your Mac Did that change anything? If the keyboard method fails lets try disconnecting the battery and holding the power button so the system is fully drained. With the battery still disconnected plug the MagSafe the system should spontaneously start did it?
