boltzwagon, first I'd try to reset the power manager: unplug the ac adapter, take off the battery and push on the power button for 5 seconds then reinstall the battery, connect the ac adapter and try to boot the ibook.

You say the ibook doesn't boot but do you ear a hard drive activity and the reset sound of the optical drive when you push on the power button ? If no activity at all then you have an electrical problem caused by:

- a bad AC adapter combined with a dead or low battery

- a faulty power switch

- a bad DC board

- the DC board cable connector is not well inserted in his socket under the motherboard

- a dead motherboard

To check if the problem is related to the power switch: take off the ibook top case, disconnet the power switch connector from the motherboard, connect the ac adapter, carefully enter a very small flat screwdriver inside the power switch connector and briefly short the two pins inside the connector. The ibook should then boot and you now know that the problem is the power switch.
