One of mine did the deathbead GLOD thing, where it would work sometimes and then degrade, before finally not cooperating at all. A new power board cured that problem. I figured tha…

Generally when I get something with no docs I put them on the shelf and look around on the web. Sometimes while looking for something else I find a thread that leads me to the know…

From experience, info on the 2400 is tantalising but, sadly, dying out. My own machine arrived totally intact (complete with original box, all cables etc. - totally pristine if tru…

Thanks to everyone for their comments and suggestions. This is what I've found: Machine ID: 406 ROM Version: $77D.45F6 MacOS ROM file Version: 8.4 The ROM is apparently the sa…

I'm partially there. Fortunately the donor machine was basically the case and the mainboard so it was pretty easy to remove. On the customer's original computer I have the heat s…

To save you from endless speculation about the ROM version currently in your Mac, and which ROM that might be, you could go to Production information at the foot of the System Prof…

Thanks for all the responses. [] ]'> The ROM on my B&W G3 CD is 1.4, and on the 'retail' CD it is 1.6. Unfortunately neither one will boot my G4. When running th…

[] ]'> Try install another Mac OS 8.6 with MacOnMac on the SawTooth, and put the 2.5.1 ROM in the new installed system afterwards... [] ]'> And... can I have the.…

I see there was a firmware update listed for the sawtooth G4s in 2001. It says it is for improved compatibility with OS X. I'll need to learn how to use Open Firmware to see if tha…

Ugh. A mobo swap in those is a long process. It is fortunately rather straight forward, and less blood drawing than an 8500. I wish you luck and much patience. TBird

Looks like liquid may have spilled onto the board at one time. I'd also replace that 5 pin IC next to that burned out IC, along with that capacitor between them. I small soldering …

Well, an update, though not one I'm happy about. I think I may have found the problem. I found a section of the logic board towards the very front, near the front latch, that loo…

It's possible it has a grounding problem because my iBook clamshell did not have the ground wire screwed into the metal shield and I could not get a charge or use the power adapter…

The iBook G4 may have been (relatively) free of the bad GPU issue, but it still had a fairly common issue: cracked solder joints, typically in the power section. There are some web…

I'd go with a firmware update. Its unlikely that OS X would have anything to do with it - despite the fact that I primarily run my iMac under Mac OS X, it will quite happily boot o…

You might be able to instal directly in Open Firmware.

Might be a firmware update, yeah.

Good news: I got a hold of ROM 2.5.1, on an installation CD for a G4 system. [] ]'> Bad news: The CD won't boot my G4! [xx(] ]'> According to the system profile…

I have a USB2 PCMCIA card that I can use if that particular change is made.

For my Lombard I just pulled 5v from the pads on the bottom of the mobo from the USB ports. They are nice and exposed and it is super easy. I have never used much more than a keybo…

I've heard of some people (like this one) using the +5v from the PCMCIA card cage to run the fan off of a little switch they've installed. May be worth trying, or googling for othe…

Can't say I know the inside of the Lombard too well so I might be well and truly off the mark here but is there any sort of thermal sensor that's tripping (or in this case not trip…

I replaced the fan and it was spinning OK when installed. Heck even the original one looked OK.

Can you spin the fan with your hand? Check the connections.
