Powerbook Kernel panic

Hi all,

I'm having a problem with a powerbook G4 1.67ghz/1gig ram/17". The powerbooks keeps kernal panicking, it could happen at any! I have rebuilt the machine and replaced the ram. Another problem that I have realised is that on the odd occasion when it does crash, when I reboot it just beeps at me four times and the light flashed on the open latch......screen is blank!

This crashing is becoming more frequent and I'm running out of ideas on how to resolve. I have also tried TechTool pro and Disk warrior on the drive.

Anyone got any suggestions?!?

Smiffy.
 
It's "kernel". The "kernal" was Commodore's ROM-residing operating system part or something. Maybe even then a missspalling. ;) -> http://en.wikipedia.org/wiki/Kernal ...

Your problem certainly sounds like a hardware problem, and I'd have figured it would be the RAM also. It could be, though, that it's the RAM _slots_ instead of the actual RAM, and that could certainly be a bad problem. I'd have it checked at a repair centre...
 
4 beeps = Bad checksum for the remainder of the boot ROM

Call Apple for service.
 
I'm glad you found that amusing! I chuckled a little myself whilst writing it then had a vision of a powerbook in a 1000 pieces on the concrete!
 
Wow. Yeah, and it's what, USB powered? ;) ... However: I sure would _love_ such a feature. :)
 
Yeah its a pretty sweet feature! Anyhow, getting back to the subject!!! I ran an Apple hardware test on the powerbook, it wouldn't go past the logic board test and failed with the following error:

2 fan/4/1 : rear left exhaust.

I'm sending it back to Apple for a warranty repair anyway but thought you might be interested in my findings!
 
It seem like the fan stop working. it possible your mac was overheating, so maybe it not the kernel, it the fan that is not functioning properly.
