will this procedure remove my warranty? I have applecare for another 2 years, Laptop was dropped on the side, there is a very small dent on the side of I/O.

If I am facing the MacBook like I'm surfing or typing, this I/O board is referring to which side of the MacBook? Left or right side? How about replacing the other side of I/O board? The other side I/O port are part of LogicBoard? If I want to replace it, need to replace the whole LogicBoard? TQ.
