Hi all

Seems that my power adapter no longer wants to glow orange while charging the battery. It always stays green, although the battery does get charged. This behaviour started after upgrading to 10.3.3... anyone else have this problem? I'm on my trusty 600MHz iBook G3.

Nope, fine here (same iBook). Have you tried the PMU reset? After an overnight charge to be sure the battery is full, unplug your iBook, take out the battery and press the little reset button. Then start it up again; the clock should be reset I think, maybe not if you've got a net connection. Anyways now you'll have a clean PMU, so let the battery drain and recharge to calibrate it.

If it doesn't work, it could be that the light in the adaptor is broken...

Thanks for the tip, I'll give that a try.

Fine here too. iBook G4 1GHz.

I just recently started to have the same problem. If I watch the adapter it'll change from green to amber and back and forth. It's annoying and the battery never gets charged. I'm going to try the PMU restart though.

BTW, I searched the apple site but didn't figure out how to reset the PMU. Anyone know how to for a G4 ibook? I've looked everywhere for the button.

If memory serves, it DOES say what to do for iBook G4s on the page that was linked to in a previous post in this thread.
Here's what it says;

http://docs.info.apple.com/article.h...num=14449#faq6

iBook (16 VRAM), iBook (14.1 LCD 16 VRAM), iBook (14.1 LCD 32 VRAM), iBook (32 VRAM), and iBook (Opaque 16 VRAM), iBook (Early 2003), iBook (800 MHz 32 VRAM), iBook (900 MHz 32 VRAM), iBook (14.1 LCD 900 MHz 32 VRAM), iBook G4, iBook G4 (14-inch)
For iBook (16 VRAM) computers and later models of iBook, there is no physical reset button.


1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the power button to restart the iBook computer.

Hope that helps.

Welcome to the club. There was a big brouhaha a year or two ago about the adapters ceasing to turn amber. The way to fix it is to get a new adapter (unless you can figure out how to fix the LED (or whatever mechanism inside) of the power adapter plug.

Hey, thanks for the follow-up. Good (or sad?) to know I'm not alone on this one. The PMU reset didn't work so I guess I do have a broken light inside the adapter. Not really a huge problem, at least my battery still charges.
