Attempting to resurrect dead 1 GHz DVI PowerBook motherboard.

What are the minimum components required to be connected for the motherboard
to show signs of life?

I currently have these connected:
- power-in connector & pcb
- power button
- 3.6v backup battery pcb
- headphones (to hear the boot gong or error beeps)

What else:
- keyboard?
- hard disk?

All I'm looking for is a boot gong or error beep code.

Also looking for group, mail list, or other forum that has the greatest
wealth of PowerBook hardware repair discussion. Suggestions welcome.

Thanks,
