Thank you for this write up. I was able to change out a bad logic board on my mid 2010 macbook pro that my ex wife had ruined with a spill of a soft drink. The heat sink on the new-used logic board was in worse shape than the original heat sink, so I had to swap them out. Wouldn’t have been able to do that without this guide. Once again, many thanks on helping to get new life into my 10 year old macbook pro :D
