What is the black tape on the lower case?
I got an issue on my MacBook Pro 13", I opened the lower case and I noticed some kind of metal dust all over the components (motherboard, memory, speakers). After some search I found the source and it is some kind of black tape placed in the lower case, it seems like it is related to the memory. What is it? Where can I buy it? What is the role of this thing in the lower case?
I uploaded an image highlighting the tape that I want do replace: http://postimg.org/image/6ce97e5qn/
Is this a good question?
