I recently took apart my iBook G4 to put a new CD drive in. Mission successful, but now I have the unwelcome side effect that my laptop won't sleep when I close the lid. If I manually choose sleep all is fine, but even though I changed the power saving to best battery it won't sleep with the lid closed. Is there something I forgot to reconnect? I followed an extremely detailed guide on ifixit I'm almost certain I did everything right when I put it back together. Is it possible that something is simply misaligned because the case doesn't feel quite as tight as before. *EDIT* Sleep works OK on a timer too.
