iBook 600 MHz G3 here, and that happened to me back in July 2003. I've only needed to reset it once since then.

Unfortunately it did develop another problem now: I can start it all well while connected to the mains power. As soon as I pull the plug, it goes to sleep, and I cannnot wake it unless I reconnect the power adapter. The battery is full, and less than 1 year old.

Any ideas of whether this is repairable with little effort and how?

Sounds like Power Management again. A hail-mary might be to do a complete NVRAM reset. Search for "nvram-reset" on Apple Support. Basically, we want to boot into OpenFirmware and run the two commands to reset the iBook to factory settings.

There is a chance the battery, while still holding a charge, is failing in some manner. It may not be telling the iBook it has a charge.

Hint: don't run the iBook with a full charge all the time. A laptop likes to be used like a laptop, with the battery being partially a few times a day.

I've seen this (with a different model). I never solved it. :( The computer just stops knowing that the battery is there. You might try cleaning the contacts with the eraser end of a pencil... It may be that the battery has gone bad (despite its relative youth). m.

I did notice it did not recognize the battery - the menu bar symbol with the cross in the battery. Cleaning contacts made that go away, it shows the battery as being charged (even though the charger still charges - yellow light), and 0% - there is definitely something wrong here. I did all the reset-nvram and reset-all in open firmware.

Looks like it is time for a new one ... The battery was exchanged by Apple on the exchange programme - I'd guess from the behaviour that the charger actuall charges the battery ok, but the computer seems not to recognize the battery, at least it behaves as if it was not there. Not bad - 6 years for a portable.

Thank you for your help.

Well, sorta. Try Apple's page for their recommendations:

Perhaps I wasn't clear. I meant /exactly/ this:

"An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge."

Factor that trip home and a recharge in the home office, and you have your "few times a day."

LoL! I guess I wasn't being clear myself. I was agreeing with you, broadly speaking, and attempting to provide more detailed info in case the OP wasn't familiar enough with Li-chemistry batteries to clearly understand what you wrote.

Ah! The joys of the written word! :-)

Ah, ok then. I do this myself. I wasn't sure if I was being unclear or not. However, yes, that is the exact document I read, lo, those many years ago (I note that it has been updated to read "MacBook" instead of "PowerBook"). Followings the instructions therein has led to many years with a G3 iBook and only two batteries (so far).

Actually, three, since I was able to participate in the recent laptop battery exchange.
