Recently i’ve decided to start collecting laptops alongside desktops and I bought a pretty decent iBook G4 1ghz. It was listed as freezing at boot so I figured it would just be a dead hard drive and easy fix. Basically I got the computer and after taking it apart the cause of the faulty boot was found to be the optical drive. Whenever the optical drive is plugged in the computer hangs, when unplugged, it functions perfectly. I hooked up a replacement ribbon cable and drive thinking it was either of those, and to my dismay the computer still hangs even with a known working optical drive. I don’t know much about super technical things like logic board malfunctions and all that so i’m wondering if someone here can help me diagnose what’s wrong and possibly help fix it. Thanks.
