A strange power problem I can live with, but would like to know what it is

Question

Ok, for about 6 months or so, my 1 GHz 12-inch PowerBook with 768 MB of RAM, has been having a strange problem with charging the battery. The problem has recently gotten a little stranger, but nothing too major (it could probably be fixed with a part I'm guessing). Sometimes, when I plug it in, the battery icon on my Menu Bar will change from charging, to running on the battery and back to charging, until it will finally stop changing and charge up. Now, let's get to the strange part. Last week, when I ran it off of the battery and plugged it in to charge, the battery icon on the Menu Bar changed into the fully charged symbol (it will show a power plug, telling you that it is fully charged up). I also noticed that the LED's on the battery itself were not indicating a battery charging process. I played around with it (unplugging the AC adapter and plugging it back in) and it eventually started charging again, and it fully charged the battery. Today, I did the same thing, ran it off of the battery, and when I plugged it in, it eventually started charging without me fooling with it. Anybody have any ideas? I thought this was kinda strange.

Have you tried Resetting the Power Management Unit (PMU)?
