#Macbook logic board replacement serial number serial number

I was wondering if a change of fingerprint button from a 2018 Mac could cause this (although I ordered a 2020 button from china). When logic boards are replaced in a system, the technician is supposed to update its serial number to match that of the Mac's chassis. Now I have no clue why software says different serial and 2018 and customer thinks we 'did something' to his board that by the way Apple said could not be repaired. Now the serial number on the ABOUT THIS MAC window shows SystenSeUmb and theres no serial number. It said that my Mac had an unknown manufacture date and no serial. We have changed the charge port, power button and reinstalled the software. Today, I opened up an application to see check how my battery is going along, health, etc. He did bring it to Apple before coming to us and when he brought it in I only registered the bottoms serial which showed 2020 mac pro. So I cannot explain the customer how the serial number 'changed'. Only in the software 'about this Mac' the serial number does not correspond with the bottom plate and states 20. To find the board for your model, choose your model from the drop down list below or search through the chart below for your model. Its a 820-01949 2020 model, the housing matches it has a physical ESC key which 2018 does not have. We carry replacement logic boards / motherboards for all Macbook, Macbook Pro, and Macbook Air models. So the discussion is not if this is the correct board. I am 100% sure this was what was brought in as exactly the same pin on the charge port is corroded, I made a pictures of it. I did not have the board at hand, that's why I have not mentioned the model, but it is 820-01949.
