2 round plastic pieces blew out of the case?
After replacing my trackpad in my mid-2010 Macbook Pro, two 4-5mm round plastic pieces blew out when I was blowing dust out. I don't know where they came from. They aren't flat, but are cupped about 1mm, and they have 4 pinholes in the bottom in a square configuration. They look like caps, but I can't find where they fit.
As a side note, why does my case clearly show my Macbook Pro as a A1273, when everything I've read says that it should be A1278? A misprint?
Thank you in advance.
Is this a good question?
