Bummer... didn't fix a thing. Happely I could reboot my machine by first removing its memory and then inserting it again... :(

Hi there,
I'm seeing similar problems with my G4 iBook bought september 2005. Due to lazyness, I'll just quote (from this thread) the symptoms I'm seeing:

I will add to this that the problems getting past the start-up chime only seems to appear when airport is turned 'off'. Restarting proceeds as normal if airport is turned 'on'... until the KP occurs, that is ;)

Now that's interesting... I hesitate to try though, because at the moment I don't have time to spend hours on rebooting if it fails...

I can sympethise.. I've just returned from a work stay abroad, and due to the start-up problems, I have been using the ibook for 5 weeks without turning if off, only putting it into sleep mode when not in use. Without turning airport 'on' or the computer 'off', my iBook has been working flawless all those weeks. It's only now that I'm back, and switched on my airport card again, that the KPs started to re-appear.

okay, i've been following this thread for a few days now and it took a minute to get registered, but i'd like to share my experience with this problem as well.

a few weeks ago (nearly a month now) i downloaded the latest updates from apple. i'm uisng a G5 iMac that is almost 2 years old now. pre-Intel and pre-iSight. my roomate has an airport hub and we all run wireless through that. one morning i woke up and my airport bars were empty (this never happens). so i went in and clicked on a different connection (there must be 30 people in our brooklyn apt. complex with wireless). upon doing this my airport icon disappeared entirely from my top bar and i could not connect to the web, so i restarted.

bad idea.

i got a kernel panic almost immediately and proceeded to get panics for about 15 more restarts. i tried everything from zapping my pram and nvram, starting from my install disks and running disk utility, deleting login items, deleting 3rd party apps. everything, and to no avail. safe mode starts up without any problems, as others have noted, but i can't get a normal startup to save my life.

so i called apple and since i'm out of warranty they made me pay 50 dollars for them to "troubleshoot" the problem. of course the guy told me to do all the things i'd already tried. he didn;t even know what verbose mode was or how to resolve a KP, and he charged my credit card twice. so i called apple the next day and they deleted BOTH of the charges, since they couldn't fix the problem and because i told them that there were entire forums devoted to this issue online that they needed to see (forwarded them this thread, hope that's alright). they denied any knowledge of the bug.

and they told me i needed a new logic board and to take it to the nearest apple store. the thing is, i read in this thread that others have replaced their boards to no avail. so i haven't done that yet.

and i don't know how to turn airport off. i go into "network" in my preferences and it says "airport is currently turned off," but the comp won't start up outside of safe mode.

so has anyone figured this out? because right now i have a 50 pound paperweight in my room and it's bothering me. i can't run my website without it, or work on the animations that i'm required to do...

anyone know how to get it to startup in normal mode so that i can use an ethernet cable to connect without wireless?

please let me know, and kudos for starting this thread.

hi all, i've made some experiments and i've come to something, so now i'd like to have some feedback. Please try to do the following:

when you have airport turned on and you are experiencing kps, try to boot the ibook while pressing strongly the down side of the laptop under the left alt/option key.

i've noticed that if i boot this way, everything goes flawlessly until i put the ibook back on the table. when i do this, i get istantaneous kps.
please let me know if you experience this.

now the speculation part: what if there's a chip on the logic board involved with airport that is loosely soldered? what if this chip was used by the software in a different way until 1 or 2 months ago? notice that a loosely soldered chip was an issue on old ibookg3 logic boards also, although the design of that logic board was much different from ours, and that an issue like this can trigger very strange and erratic behaviours..

See http://www.applefritter.com/node/10193 That article. They're saying the whole KP/logic board error is due to a bad chip and you can fix it...I still have yet to do it cause I need my laptop to finish my final paper, but I'll try it next week and see what it does for me.

I checked this serveral times.When I boot without the presure under left alt/ctrl. I won't get graphics. If I do, I get them, and the beast boots...

and how about kernel panics while running airport and keeping this spot under pressure? does it work?

if so, maybe this tutorial can help to apply permanent pressure:
http://www.coreyarnold.org/ibook/ (though i don't know if the chip in this tutorial is located under the left alt key)

it's a link from the page Hairnester suggested...

I'm going to give it a try now... it is a heavy device... so i keep squeezing :D

good luck!

This only helps to boot the machine... not to fix the kernel panic.

hmmm... bummer. so we have two problems now.

Which started roughly at the same time... decent hardware don't buy apple :mad:

I just want to join this forum after reading it for a couple of days.

I have exactly the same problem as the rest of you with my iBook purchased in November 2005. It happened after updating to 10.4.8. Before that everything worked perfectly.

I think Hyperknight summed the problem up very well in his message on 12-17-2006. And I agree that this must be fixed and initialized by Apple in some sort of program. It's a flaw in the design, not an error created by the user.

It's obvious that a fix will only happen if many "airport panic"-users get organised and show Apple that the problem really exist.

It would be interesting to create a list of all affected iBooks and look at the actual production date or serie. Maybe also but together a simple webpage with all computer affected in a database. (not the whole serial number, just to point to production date and model)
New users could then join in when their iBook got the "airport panic".
I don't know how many cases are needed before Apple would start acting upon the problem. 50? 100? 1000?

Maybe we could create an IRC channel (#airport_panic?) for faster discussions?

it's a good idea to start a list of some sorts, because it seems we're still talking different problems here and this may help to get them a bit more organized.
i too never had a problem before 10.4.8, and this is true for a lot of us, but others experienced the same or very similar problems earlier.

sorry i cannot provide any ideas for the list(s), as i have no idea which numbers are relevant in this case, but if somebody who's familiar with hardware issues could set up this list, i'll happily provide the specs of my machine.

Survey?
 

I think about creating a webpage with a survey where you can fill in e-mail, serial number, date of purchase, problem description (booting, kernel panics, other), contacted apple.


And just figure out how many people have these issues.

Since Apple sells several million Macs a year and a large fraction of these are laptops, it is likely that there are a million or so of this generation of iBook around. So anything less than 1000 is probably not going to attract any interest.

I agree with Skinkie.
A simple webpage that clearly describes the problem and purpose of the webpage for the visitor.
Then some sort of survey to collect each visitors experiences and possible differences in each case.
For each survey maybe name, part of computer serial, production date/factory, user contact and some questions that make the user describe the their experiences.
A goal with the webpage should also be stated clearly I think.
To collect as many users with the same problem so Apple starts a investigation/repair program?

Anything else should be in before we put this online?
