My MacBook doesn‘t turn on after SMC reset. I've found on Apple pages that this can happen if you reset the SMC without your MacBook connected to its AC power adapter. I've also tried PRAM and SMC reset and nothing.
Black screen, no charging sound and battery picture when connecting to power supply.
I wonder what is this little yellow button on logic board for? Do any of you have a problem like me?
For this model MacBook it is IMPERATIVE that the battery disconnect button be held for 10s (until the tiny led dies) before removing the track pad flex, else you can kill the logic board.
On power back up post repair it is IMPERATIVE that the MacBook be connected to a standard USB charger (5v 0.5-1a) until it powers on before connecting to the standard MacBook charger. This is to wake up the power management circuit. Connecting directly to a standard charger after having disconnected the battery can likewise permanently damage the logic board.
Trying to figure out how to unlock the stearing wheel without the car on, we had to break the ignition and start it with a screwdriver but now the steering is locked and we can't start it to get it unlocked!
