I'm so sorry for such an amateur question but how do I locate the main logic board number? Not just on this MacBook but on any MacBook, im having a very hard time finding information on how to find it.
Look at the corner near the SSD connector.

Keep the battery out.
Be sure to use original 85W Magsafe 2 charger.
