Resposta para "Do i need a new upper case?"I grabbed a top case, keyboard, and track pad for my 13" MacBook from Ebay. Last count, they were anywhere from $129, to $35 on Ebay. Either brand new (in box), or used. You can find them reasonably priced there. I will post the part number for the keyboard/top case assembly a little later. Need to get a stuck cd out of my SuperDrive. FYI the part number I will post will be for the "Santa Rosa" style Apple Keyboard. I think the Santa Rosa has an Apple Logo on the command key (by the space bar). The other types simply say command under the symbol. You have to be careful, because the wrong top case, and keyboard will have a different ribbon to connect it to the logic board.
