Hello, Yesterday we disammbled our macbook to replace the keyboard because a few keys weren't working. After putting everything back together the macbook seems to be working perfect again, but....there a two pieces left over and we have no idea where they had to go...Searching on google hasn't helped me find these exact pieces, could someone identify these pieces, and maybe tell me to witch part they belong to? I've left the laptop off after testing just in case these are essential parts or something... In the picture you see the parts, the smallest part has the number NSX A2 on it, and the other part says ZY1. Thanks in advance!
