There is something loose in it, or some broken solders that are creating
problems only when the heat increases. That's a tough problem to
troubleshoot. I'm not sure but does the Lombard have a processor
daughterboard snapped on the motherboard? If so, that would be the first
thing I would try to fix, e.g. removing the daughterboard and putting it
back while making sure it is solidly in place.

Then, there is something with the power. A connector or maybe an hairline
crack in the AC/sound board or something like that. Have you tried a
different adapter?

If that was all, yes. But Thursday night, immediately after it crashed, 
the observed problem was that it wouldn't power up - no chimes, no grey 
screen, no icons, no sign of life at all. At that time, therefore, my 
assumption was that it must be the power side. Friday morning, without 
doing anything in the meantime, I idly tried it 'one more time', and it 
chimed and powered up, as far as the screen with the question mark / 
folder. So today, the observed problem seems not to be with the power 
at all but with the disk. That's what's confusing me - how can the 
symptoms & observed behaviour have changed?

Just had a similar thing happen to me. The burning smell apparently was 
the chip that controls the hard drive, on the bottom of the 
motherboard. I took the mobo out and could see that it's melted. It 
will recognize a CD or Superdisk, so it's not the entire IDE 
controller, just the hard drive.

I'm confused. You're saying it's dead bu then, later, that the Disk Utility
from the installation CD sees only the installation CD. So, it's not
completely dead, is it? If you can boot from a system or installation CD,
and if Disk Utility can't see the internal hard drive, then it seems pretty
clear that the internal drive is toasted, hence the smell...

Ongoing Problems with Lombard

2004-05-28 Thread Tom Burke 
Last night my daughter's Lombard appeared to give up the ghost. It just 
stopped dead - no sign of life at all - and would not restart - no 
chimes. Plus, when I lifted off the keyboard there was a smell of 
electrical burning.

Today it'll power up, but it won't boot - I just get the flashing 
folder / question mark icon. I have done the following things:- a) 
reset the pram; b) reset the nvram, having booted into open firmware; 
c) reset the PMU. I've also tried using Disk Utility via an

I suspect that the Lombard is dead, but I was just wondering if anyone

must be a power issue, today the power side of things appears to be OK 
and the issue seems to be with the HDD.
