Well, Arild and LF,

let's see what Apple themselves have to say about this topic
(titled "PowerBook and iBook: Resetting Power Manager):

PowerBook 160, 165, or 180
       1. Remove the AC adapter and the battery.
       2. Let the unit sit without power connected for 3-5 minutes.
       3. Reinstall the battery and, if necessary, reconnect the AC adapter.

Note: Steps 1 and 2 will usually reset the Power Manager, however if the computer still exhibits the same issue, redo steps 1 and 2 and then follow the step listed below before reinstalling the battery. 1. Using two paper clips, simultaneously press and hold down the reset and interrupt buttons for 5-10 seconds. They are located next to the power button on the back panel of the PowerBook. ----

Hope this may be of some help,

Mac and Newt regards,
