Hi, My power-button is dead, i want to try changing the keyboard before buying a whole uppercase (not the same price). But, the first time i opened the Macbook, to see the inner, cleaning it up and to power-it up unplugging the battery. I torn the black paper behind the keyboard. What is it for, do i need it if i replace the keyboard?, if i need it, what is it called, where can i buy some? Thanks a lot,
I’ve done tear downs of the the many layered keyboards. Note the circuits in black plastic. There’s no way to get all the parts. A complete upper case replacement is required.
