How can I determine the proper schematic and boardview

Schematics for this Macbook have various numbers, such as K24 and J30. I have done quite a bit of research, but have not figured out which schematic is correct. What am I missing?

Is this a good question?

Get the board number that's printed on the logic board. You'll have to open it up and inspect the logic board. It's usually 820-xxxx

Make sure not to get the number from the DC IN board a.k.a charging board.

Thank you for this. I had the board removed from the laptop, and did not see identifying characters that seemed relevant. I did see the characters on the DC in board. I will look again soon, Meanwhile things are working fine. Thank you, Ben.

I just opened the MLB. I saw this number before but discounted it because it did not correspond to any of the available schematics. It is MLB: C02107606N3DM6MAQ.

Am I just having a senior moment here....?????

It was in the vicinity you outlined. I expected white on black, but it is simply raised black. And the number is 820-2936! Thank you oldturkey03
