Will not boot, but only fan starts up. Dead DC board?
This iBook has been working fine for years, and began to behave strangely quite suddenly: the screen flashed and audio played. At restart worked at first, then it crashed. We were able to run in FireWire mode to back up some files. A subsequent attempt to startup from DVD failed (and the disk will not eject).
Now it will not boot at all: no chime, no screen display, no FireWire disk mounting. A fan starts when power button is pushed, and stops when pwr btn is held down for a few seconds. Otherwise, nothing. Tried keystrokes for PMU reset, no help.
The battery is good (4 lights) and AC adapter seems ok. Could this be a DC board problem, or is logic board failure more likely? What to test first?

I'm going to accept logic board failure as the answer to this, and many thanks to Dan for his response. I tore the iBook down, removed the hard drive and installed it in an older 12" 800MHz model. All the data is there. Along the way, I was also able to extract the DVD that had gotten stuck in the optical drive. So - I have parts! What fun.
