G4 PowerBook lock up issue found

[Macdrone]

Ok to start I had a 1.25 and a 1.67 set of PowerBooks. The 125 was kernel panic king with no obvious reason so I start pulling it apart to swap better pieces to the 1.67. I didn't expect to find what I did considering how hard I was on it while removing parts.

When I pulled the hard drive the card underneath the hard drive was burnt. Both sides. Plastic charred the whole 9 yards.

So I pull the card. I guess it's most likely the modem card as blue tooth and airport were available on boot.

So now I have this working rode hard put away 1.25 machine that now works. The support next to the DVDs drive was broke but other than that it's good to go.

I have some pictures I'll try and post when I'm not so tired.

Suffice to say this thing got so hot it got molten and capacitors slid across it. One tantalum capacitor is actually lifted on one side with a leg of solder down to the board.

Searched around, could not find any similar defects to speak of.

That's fixable. My 1.0GHz 17" PowerBook had the GPU melt to the heat sink, found out why it was making a terrible smell when I tore it apart.

That was not fixable.   It was a used and abused machine I'd gotten from a pawn shop for less than $50, and I got a year out of it, so while I was sad I did get my moneys worth.

The cards replaceable but at this moment I don't need 2 of these.  Both screens are great.  Both not pristine but the 1.67 is in way better shape.
