Last week before going through airport security, I shutdown my iBook and placed it in a bin to get
x-rayed.

When I got on to the plane I tried several times to power up the system, and only once did it show any sign off life (on one attempt the screen lit up for a second, then went back to black without the system making any sounds (ie. drives or chime)).

Before making a connecting flight I found an AC outlet and discovered that the iBook would power up while plugged in and that all four of the battery's LEDs would light up when the button on the battery was depressed, but that the system simply will not run from the battery -- all of which is still the case.

I have tried resetting the PRAM,Open Firmware, and the PMU all to no effect.

Any suggestions would be greatly appreciated.

The battery status in the menu bar constantly shows "Calculating..."

For whatever it's worth the system still recognizes when the battery is not present, so while the iBook won't run off the seemingly fully charged battery or get beyond trying to calculate its level of charge, the battery status icon will show a bttery with an X in it if the battery is removed.

i have the same problem. i have had the logic board replaced twice in the past 3 weeks and the problem is still there. apple assures me that it is NOT the battery.

That is an odd problem. The best solution is to first try another battery, as the problem can only be the logic board or the battery. If the battery doesn't fix it, you have a logic board issue. Batteries for the iBook can be purchased at the link below:
