I'm dealing with a department Powerbook that is out of warranty (some smartypants forgot to buy applecare ). The short story is that someone turned it on a few days ago and it wouldn't start up, just a little OS9 looking folder appeared on the middle of the screen. The department being a little worried that the little man running around inside the machine might just have a cold, left the computer in this state for a few days to keep him warm. So when I get to it, I first tried zapping the pram, fsck'ed it etc. I also tried target disk to see it I could locate anything unusual (like a little man) on the disk. Target disk did not work. Since nothing was happening, I put in the install disks, pressing the c button. Installation screen came up and when I went to install, the hard disk was not there to install on! So, I went to disk utility. First time I went, nothing was there. I rebooted and this time I found the disk so I ran a check on it. The check stalled and never got anywhere. Now I cannot locate the disk no matter what I try. I suspect that a cable is loose. I doubt HD failure because there were never any warnings (HD noise) - oh, and disk warrior can't find anything either. Since it is out of warranty, my impulse is to open it up and check the HD connections. However, I've never opened a PowerBook before and it seems rather tricky (this is the 1.67 model). Does anyone here have any suggestions? Anything else I can try? Where are the best instructions for opening up PowerBooks? I found these instructions. Do they seem ok to anyone more experienced with this kind of thing?
