- To reply to my own posting:
-
- It turned out is was the fuse that was blown. (I repeat, WHY
- SOLDER A FUSE ONTO A MOTHERBOARD? Jeez...)
- So, I bought a conventional 5A fuse, soldered on pigtails,
- covered the assembly liberally with heat-shrink, and soldered
- it in in parallel with the old fuse. Presto.
- The socketed thing behind the power jack is a choke inductor.
- So now my PowerBook works again. I wouldn't recommend this
- repair unless one is an experienced solderer. I`m not THAT expert
- but I was careful to insulate things carefully and use fine solder
- and a 15-watt pencil.
- Sooner or later I will find a really tiny 5a fuse and replace the
- big monstrosity I have in place now.
