I just recently bought a new ibook from apple. Well actually it was from the refurb scetion but it looks brand new to me. Its a G4 12" 1ghz, the problem I am having is that I took the battery out and after I put it back in it doesnt sit flush with the casing. Its only a small gap and it works fine it just makes the ibook look slightly off. Not sure if any other people have had this problem or if it is common but any advice would be great.
