    The iBook does not have a backup (PRAM) battery. It only has the main battery and a small capacitor which maintains the settings long enough to do a battery swap. If the battery is dead, what you are seeing can happen.


    If the battery is not a problem (or even if it is), you could try resetting the PMU and see if that helps.

    thank you ronda for the post.  i will try it and see.  one thing i have noticed is that i still have the battery charged when it happens.  the bar will be half way down.  it won't let me turn back on until i plug in the charger then it starts up.  if that makes sense, 


    thanks for the post.. will try it and post back.

    I have an iBook too, and the same thing happens to me, because the battery is cooked. The battery will not hold a charge anymore. You can replace the battery, but the battery is worth more than the computer.
