So I just received an iBook G4 I purchased on eBay for a decent price with unknown specs. Ends up it's a 2005 12" 1GB/80GB/Combo/BT/AP model (on the sticker anyway) so that is a nice bonus. On the listing it shows it booted up and on the Tiger login screen: But I haven't had any luck getting it to do squat. It didn't come with a charger, but I've got one from another iBook G4 a family member had that has since been sold for parts. And it seems to be working. The battery doesn't light up at all when you check the charge, and even after being plugged in all day it is still completely dead. So this makes me wonder how it was booted up in the first place. My guess here is that the battery is 100% dead and is not going to charge back up. And apparently unlike a MacBook these iBooks have a capacitor instead of a PRAM battery, so when the main battery is dead, even when plugged in, it won't boot up. If this is correct it looks like I need a new battery and then it *should* boot assuming all else is functioning. Just wanting someone with experience on this model to confirm. I will be contacting the seller and seeing what they did to get it to boot, or if they used another battery by chance. It looked like the seller had a lot of them. Thanks for the info all!
