I just bought a used iBook G4 1.33GHz on eBay from a seller that offers a 30 day return policy. It came today and upon boot i don't get the classic "boot sound," but instead a somewhat garbled burping-like sound. However, the iBook seems to function fine otherwise. It's a bit slow and "hesitant" running Leopard, but it's running the stock 512MB of memory so I'd expect that from it until I stick a 1GB stick in there. Also, the regular speakers work fine once the computer is booted up, so I'm guessing the "boot sound" plays on something analogous to a PC Speaker in a non-Mac PC. The casing looks good and no defects on the screen, the bottom does get pretty hot, but I think that's usual behavior from a G4 iBook, right? So, what does everyone think? I'm hesitant to make a stink over the stupid "boot sound" speaker, particularly since it might be easy enough to replace (and it's supposed to still be under AppleCare anyway, so it may just be a trip to the local Apple store to get a fix anyway). Thanks for the advice guys!
