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!
