I attempted to replace the battery on a MBP 15" mid 2014 but I can’t get it to work. It doesn’t change, it doesn’t start. Makes a strange clicking sound like once a second very faintly, sounds like a short to be honest… Tried to reset SMC, no help. Any ideas? Maybe remove all components again and reinstall one more time? Why is it making this sound? Details: Connecting charger When the magsafe is connected, charging light blinks green once, then blinks orange once with long pauses. There seems to be a clicking noise coming from the logic board (coil or mosfet?). The orange light does not blink at the same frequency as the clicking sounds. Pushing power button Clicking sound changes and seems to go elsewhere on the logic board with a faster frequency (2 Hz maybe?). Resetting SMC Holding all 4 buttons to reset SMC clicking goes away while holding the buttons. After releasing the buttons, charging light flashes green but laptop still doesn’t start. Trying old battery Same issue
Let’s give this a try, carefully disconnect the battery and now press the power button to fully discharge the logic board, now plug in the MagSafe charger what is the MagSafe chargers LED color Amber? Now try starting the system did it start?
