Recently brought my 2016 mbp to the apple store to replace battery via free replacement program... when the laptop was shipped to the service center i got a call from the apple store saying that i have to cough up $400 because the logic board was bad and the laptop does not boot...laptop worked just fine before i shipped it... Had to escalate to the manager to get the logic board repaired for free... I was mad that i would lose all my data but it is what it is and i didnt have to pay so i conceded.. More than a week later my unit comes back and lo and behold my MacOs user data was 100% intact.. How is this possible?? I thought SSD was soldered to the logic board and replacing logic board would mean lost user data. I checked the battery count and it was indeed 1... so i did get a brand new battery.. Did anyone have an experience like this? Did the service center try to pull a fast one on me? How is my data intact when they replaced the logic board??
