    Louis, I am have the same A1278 and 820-3114B board. I have power, green charger light, full battery; on power button press the fan momentarily jerks and white light on front right lower edge lights briefly. I have tried various changes i. e. Removing ram, disconnecting HD, disconnecting the battery, disconnecting the fan, tried all the reset routines etc but on pressing power button the same thing happens. It does this on bat and on charger. Now stuck in Colombia on lock down without a laptop. Whatever happened, happened after I closed up the laptop for the night, just wouldn't start the next morning. Clues? Advice? Thanks!

    I have an A1278 Macbook Mid 2012 Core i5. Old owner used it with a janky power supply and it always felt like the body was sometimes stingy like minute electric shocks while plugged in. Of course after some days my audio failed, no output devices showed up in system information, and now the macbook does not turn on, and sometimes it does by itself if I leave the lid open, boots up all the way to the login page and then powers off. I'm very confused, the Magsafe shows green light and the battery indicator shows the battery is fully charged. The battery was already over a 1000 cycles so that's that.
