What is this thin black layer under the keyboard, is it important?
When attemprintg to redo the thermal paste on an early 2011 macbook pro 13", I was having great difficulty removing the logic board as it seemed to be stuck on something underneeth it. After much gentle wiggling I finally got it off but have ripped a hole in the thin black material that goes above the logic board and is just underneeth the keyboard. The inside of the hole is still stuck onto the heatsink, so should line back up when reassembling the laptop.
What is this material and what does it do? Does it need to be replaced because I broke it? Can I just tape it back on? Where can I find a replacement part?
Thank you very much for any help :)
