My buddy has an old 1.42ghz iBook G4 that has run flawlessly for 4+ years but just today he was greeted by a few kernel panics back to back for no apparent reason. I suspect that his HDD might be going south, as his Crucial RAM upgrade has been working for over a year. When it first crashed he was moving files to the trash, after the restart it crashed again on the login screen. Took him several restarts to get the machine booted at which time he saved the crash log.

Just wondering if any info jumps out at somebody here. He is teaching now and uses his 'book on a daily basis. I am curious whether or not he should let me have the machine over the weekend to do a proper troubleshoot.

Have you tried running the hardware test disc?
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

Well, I would have liked to keep the machine for a few days in order to troubleshoot properly, but he needs it to teach classes and whatnot.

Another newer item is a battery he bought to replace the kaput apple one so that makes three possibilities in my mind, because I've never seen an OSX installation crap out for no reason before.

The battery is bad/odd/not seating correctly
The RAM has gone bad (it's Crucial brand)
The HDD is failing

I'll convince him to give me the 'book for over the weekend because I don't like the look of this situation. This iBook has run with zero problems for 4 years and now, within one day, it has crashed more times than in its entire lifespan. I was hoping the resident nerds would be able to garner some info from the crash logs, god knows I can't, but if that isn't the case I'll do a full diagnostic on it this weekend.

It could be the logic board. My iBook had its logic board replaced four times before my AppleCare was up. I started having similar random kernel panics.

Run the hardware diagnostics. Make sure you remove any upgrades or peripherals. Hopefully it's just the ram!

I had a 12" 1.33Ghz PowerBook given to me, diagnosed as having a faulty logic board, due to kernel panics.

I booted it up, listened to it and it was obviously the hard drive. Noisy and seemed to pause as if struggling to read data.
Replaced HDD, all working fine.

If you can run the application Smart Utility on it, that'd be a good start.
Post the attributes here.

I'll get to it over the weekend and see what SU says, thanks for the tips guys.

Talking to my friend over the week he says even when the machine is running it beach-balls constantly. I know it's an aging PPC computer but honestly the machine has always run very well for its age, especially after the RAM upgrade (total 1.5GB). The fact it still boots, but has been going through kernel panics and beach-balling makes me suspect the HDD first and foremost, especially since that is usually the weakest link, longevity-wise.

Dodgy HDD would also cause excessive beachballing, but then so would visiting flash websites on an old iBook.
I have plenty of more important things to do, if only I could bring myself to do them....

Ran Smart Utility and got bump-kiss.



Machine has been running ok, no kernel panics since then but it still is beachballing at inappropriate times.

Next question would be how much empty space the HD has?

That was my first question when I met with him over the weekend.

8GBs, which is more than enough AFAIK.

Doh, looks like that drive has been replaced before. I'm pretty sure iBooks never came with 80GB HDDs as standard.

I'm pretty sure this machine did come, from Apple, with the 80GB drive as a BTO option. Otherwise you would seem to be correct that this machine shipped with a 60GB as standard.

At any rate I have instructed him to back up all his important data, and I guess he'll continue to flog the machine until the HDD dies. I hear these machines are nice and easy to slap a new HDD in, so that shouldn't be a problem for me.

I just really, really hope it isn't the logic board.

Hmm, Mac Tracker says 40, 60, 80 or 100GB, maybe I'm wrong.

RAM could be the problem...
You could really do with testing it booted from a fresh firewire installation. If that's OK, it rules out the internal HDD and S/W issue. Then, clone the internal HDD to a firewire HDD and test it booted from there to rule out the internal HDD and test the software.

Check the airport card! I think those ones still had airport cards. My old 12 inch PowerBook KPed all the time for a while to the point where I got a new machine. After a while I tried using it and it would go for a while but then eventually KP. At one point I noticed my WiFi reception seemed wonky, so I popped the card out, popped it back in, never had another KP on it. It's been running as a bittorrent server for the next two years.

The 1.42 had a dedicated wireless card, not a removeable Airport Extreme. Also changing the hard drives in iBooks isn't hard if you are comfortable with remembering where lots of screws go. Many of them are marked (unlike the G3s) but I used to see iBooks regularly that people had attempted to rebuild themselves and failed miserably. Mostly lots of lost or misplaced screws but in some cases they gave up and handed me a bag of bits to put back together.

You need to remove the bottom case, the bottom heatshield, the top case and then the top heat shield to get to the drive, unless you don't mind bending the top heat shield which will save you about half the screws or so and won't really do any harm, just doesn't look so pretty for the next guy who opens it up.
I have plenty of more important things to do, if only I could bring myself to do them....
