I brought my iBook 12" 1.33ghz in to have the trackpad replaced and when i got it back the combo drive didn't work at all. In fact the computer refused to acknowledge that it had an optical drive. I decided, instead of bringing the computer back in and waiting for another week, I would just open up the iBook and see if it was jhttp://www.ifixit.com/Guide/Mac/iBook-G4-12-Inch/Optical-Drive-Page-10-DC-In-Board iBook G4 12" Disassembly: Installing Optical Drive - Removing DC-In Board (page 10/18)ust a loose connection. I opened up the computer, following iFixit's (previously pbfixit) directions. The directions only specify that they are for up to the 1.2ghz model, but I figured I'd see how it went. It went fine except when I disconnecting the optical drive the part pictured below popped up out of nowhere. I can't figure out where it goes. It is metal but the black part you see is foam. It is roughly 2 1/2 - 3 1/2 inches long. Now after the 2 hours i spent taking it apart and trying to figure out where the random part went, I said, "screw it," and put everything back together minus this one piece. And guess what, the computer now found the optical drive, saw the blank CD that I put inside the computer about 2 months ago (when I first got my computer back), but couldn't eject it. It tried, made the eject noise, but it wouldn't come out. So now I want to bring it back to Apple. I still have about 4 days left on my original warranty so they should do it free, but I'm worried that if they open up the computer and find a part is missing that they will blame the problem on me. So in conclusion, does anyone know exactly where this part goes? Many thanks! And of course, merry Christmas and holidays!
