kernel panics on a dozen different machines / models
I maintain 120 Macs & have had very few kernel panics over the years. Over the past few months, I now have a dozen iBooks that won't work or will work only in single-user mode. Five of these are 1.33 Ghz. I've read much on iFixit about iBook KPs, including the Airport-on-logic board problem. Thus far I've tried only software fixes (applejack / disk repair / memtest), with little/no success.
1. The 1.33 Ghz machines KP right after login unless in safe boot. In safe boot Airport is disabled but only until next boot. Can I 'permanently' turn Airport off somehow in safe boot (or otherwise)?
2. the other machines (1.0 & 1.2 Ghz) - despite my reading, I'm clueless how to proceed. Suggestions?
Thanks in advance - this is a great site/service!
For a test, install a system from the original installation disk. These are eight year old machines and may be coming to the end of their lives. If the reinstall fails, replace the airport card on one. Also after this amount of time it may be necessary to start fully tearing them down, clean the vent ports and heat sink and reapply thermal paste.
