How to disconnect MacBook Pro 15 2017 battery? I'm struggling to figure out how to "unplug" or disconnect the battery of my retina MacBook Pro 15' 2017 from its logic board, to reset the SMC.

What cable(s) do I need to disconnect exactly? 

Those?





Thanks in advance!
Sometimes it helps to look at the replacement part to see what connectors it has.

From this picture, we can see that there is a PCB and a small connector cable at the top of the assembly.
This would correspond to this part in your photo

Disconnect that, and your SMC should reset.
