I completed this replacement successfully, with one glitch and two leftover items. The glitch: I failed to insert the keyboard ribbon cable at first. The leftover items: A multilayer soft pad, silvered, about 3x1 ¾-(7.5x4.5 cm) and a piece of foam in a quarter-round shape, 7/16”(1.2 cm) long, ⅛"(3-4mm) ,on a side, with a fine metal mesh on the long sides. I don’t recall in which step I removed either part. I’m hoping neither is critical, but I’ll replace either as best I can if I’m wrong. I have a photo of the two parts but I don’t see how to add it to the post.
