I replaced the logic board on an early 2014 MacBook Air and the laptop booted right up into OSX. I was able to use it like normal and then shut the system down. Now when I go to turn it on there is nothing, no boot no sound no nothing. I’ve tried all the resets I even reseated all the connectors on the board itself. Has anyone encountered this problem before? I’m stumped any help is appreciated.
Lets give this a try, disconnect the battery, then press the power button for a good 15 secs. Then carefully plug the magsafe back in did the system spontaneously boot up? If it did then the battery has a problem! If it didn’t the logic board is damaged.
