dropped my macbook air and the logic board was damaged
It was an incredibly easy process. I just followed the step by step instructions on Ifixit for removing the old logic board and installing the new one. I did not need to look to any outside resources for additional instructions
keep the small screws from each step in separate containers (I used shot glasses). many of the screws look the same but they are all slightly different so you will want to have the grouped by each step in the process.
