    My fiancee dropped her iBook G4 from about a foot off the ground a week ago and has had kernel panics since then (the kernel panic messages look like those I'm posting below):

    Code:

    Anybody know what that might mean? Does it mean that AirPort is the problem? That would be consistent with the fact that her computer runs completely fine in Safe Mode (AirPort is turned off in Safe Mode).

    Anyway, I performed a hardware check and nothing was found wrong. I did a 'archive and install' and the problem still occurred. I did a 'clean and install' and the problem still occurs (except, again, that it works fine in 'Safe Mode').

    What should I do next? Is it possible to see if the AirPort card is damaged or dislodged without taking it into the Apple Store? Also, she bought this in 2005 so the normal 1-year warranty has since long expired. If we take it into the Apple store, what sort of charges are we looking at for them taking a look at it?

    Thanks for your help!

    Why not just go get a new MacBook? It doesn't seem worth it to put money into this computer, as it is so old.

    Well, she still likes it, so no need to buy a new one if she's happy with it. I wasn't sure if the Apple store helped for free and then would tell you what the replacement hardware would cost, or if they'd simply start charging $50/hour or something just to take a look at it. If the costs of fixing it is over a couple hundred dollars, then yes, I agree, she should just suck it up and get a new one :)

    They will help for free, but charge you for diagnostics, repairs, and whatnot...

    I see. Thanks for the info. Just set us up a Genius bar appointment for Tuesday. I imagine they'll say "Yep, looks like you're $@%&ed and we'll have to ship it off to find out more" and then say no and move our way over to the new laptops.

    Assuming she gets a new one, is there anything semi-useful that we can do with the old one? Do computer stores pay for laptops that have some sort of problem (I suppose Apple doesn't do "trade-ins").

    Apple may give you $100 for it... but that's all...

    You can check the AirPort card quite easily. It's under the keyboard, which is released by 2 spring-loaded tabs in between some of the Function keys. The keyboard will then simply lift off and you can re-seat the AirPort card.

    The easily-removable keyboard is probably one of the best features of the computer. Also, FWIW, this should be in the PowerPC sub-forum, not the MacBook sub-forum.

    I don't think this is true with her model (I saw a Youtube video where this was true). I removed the keyboard yesterday and there is nothing sitting there except a metal grate which I suppose leads to the hard drive. I believe with her specific computer I have to take the computer apart much more in order to get access to the AirPort card.

    Oh sorry, I didn't really know what the iBook was considered. I guess I just thought it was the MacBook predecessor. If a mod could move the thread that'd be great.

    Which model do you have? To my knowledge, all iBook G4s have the AirPort card in the same location.

    The guy who made this video (http://www.youtube.com/watch?v=egYtb6MBnJU) says in the comments that in the 1.33 GHz G4s there is an internal AirPort card that you have to remove the top casing to get under. Hers is a 1.33 GHz G4.

    There you go. I learned something today.

    Those things are a pain to get apart, but not at all impossible. If you've got the tools and skills, I'd give it a try. You don't have a lot to lose... she doesn't have a computer that works well enough right now, so if it broke she wouldn't be much worse off.

    That's exactly what I was thinking. I'll see what the guy at the store says, but I'm assuming he's not going to be able to fix the problem for free. Then I'll take it home and open it up. If it's going to be worthless then I might as well have fun opening it up. At the very least I'll learn something and at the very best I'll fix the problem and save $1000.

    tl;dr? We already discussed how this iBook has the AirPort card on the logic board, so you have to take apart half the computer to get to it.

    Went to the Genius bar last night. I basically told them everything that I wrote in this thread and he agreed that the AirPort card might likely be the problem. One thing he did that I didn't was boot into standard mode and then turn the AirPort card off (I had only operated in Safe Mode with the card off). The computer worked fine in standard mode without the wireless card activated.

    So he recommended that we just get an external USB ethernet and go with that, which sounds like a good idea to me. Does anyone have any recommendations on a good one? I've never bought one of these before and don't know how variable the quality of these are.

    As for reliability, I can speak for a buddy of mine that's had one on his desktop since I met him 4 years ago. The thing is still going strong, and he's never had any issues with it. If I get a chance to ask him what the brand and model is, I'll let you know, but since it's fairly old, I don't know if that'd help or not.

    Regardless, those things are great. Very strong, and basic - the best part about basic technology is that not a whole lot can go wrong, since there's not a whole lot there to begin with.

    Great, thanks Skippy. Perhaps I'll just meander over to Newegg and see what gets good reviews.

    It looks like you the 1.33ghz model which is different than all of th other iBooks, the airport card isn't under the keyboard, anyways this is a very common issue and you can find a lot of information if you google 1.33ghz airport.

    You can take the iBook apart and shim the airport in place, just put a piece of cardboard betwwe the card itself and the supporting plastic part.

    Or you can resolder all the connectors on the logicboard if you have a good soldering skills.

    Ps or the card could be simply loose since she drop it.

    Having had one of these, I can say that it's not too terribly daunting. All you have to do is go to iFixIt or a similar website and look at the service manuals... As long as you just do exactly what they say, anyone can do it! :)

    They are awesome little computers.

    Thanks for the replies you two. I think there's a pretty good chance that if I followed directions online I could replace the internal card without damaging or breaking the computer. But I've got my qualifying exam in a couple weeks so I'm worried about that taking up too much of my time. Getting an external wireless USB would probably fix the problem without me having to open up the box and worrying about it.

    But if it doesn't work, or if something breaks in the future, that iFixit site looks great for repairs.
