Well I can tell you it's NOT a dead battery. I have the exact same problem with my old Macbook Core Duo. I have several old batteries and a couple of new ones, and all cause the same behavior. 1) All batteries will charge 2) Adapter LED goes from orange to green, and the batteries peak at 97-100% 3) Macbook will only turn on when plugged in. 4) If not plugged in to AC, Macbook will spin up the drive, no chime, then spin down. Of what I can find online, it's either something wrong with the battery connector circuitry, although everything, even coconut battery utility, says everything is within normal limits. Or it's the logic board.

I completely agree with joshAU. This design is the worst hardware I’ve ever had the displeasure of having to deal with.

Impossible if you don’t have this tutorial.

Perfect!

Anyone suffering from a broken iBook G3 screen should start with this approach.

There is no need to take ANY of the lower body apart in order to replace the LCD.

Just remove the rear display bezel as per this set of instructions, then find the iFixit instruction set for replacing the LCD.

You'll have a new screen installed in about 8 steps and 10 minutes instead of the 36 steps and 2 hours it takes to remove the hinge assembly of the display first (requiring the lower body disassembly.

First of all, awesome guide. I am using it in July 2015, and there is no way I could have successfully navigate the typical Apple laptop Rubik's cube of Powerbook maintenance.

Second, there is a REAL trick to removing the upper case here, and it involves knowing what those stupid internal metal catches look like so you can free them without folding your aluminum case into a pretzel.

Another PERFECT iFixIt guide!

Had to replace the screen in one of these little beauties, and this walk-through worked like all iFixIt tutorials: Flawlessly.

Kudos Mr. Barker!

I've done this procedure successfully 3 times. On my fourth attempt, I fell victim to the dreaded Speaker Jack Motherboard Disconnection Nightmare.

Oh the silent humanity. Sound still works from the audio out jack, but I'll add my voice to the "hold the jack down to the motherboard while you unplug the connector" chorus. You might even try carefully applying superglue to the jack to the motherboard BEFORE attempting to remove the little connector from the dainty, fragile jack.

I wouldn't have even attempted this procedure without Walter Galan's excellent iFixIt base walk-through. Thanks Walter!
