    Hi guys, havent posted here in a long time...
    Im 13 now btw.... anyway

    I just got an old 2005 12 inch iBook G4 from my uncle. It won't turn on and I don't know what the issue is.
    Heres what I know:
    The battery is fine - led indicators on bottom seem fine.
    The charger is brand new, and working.
    The iBook itself doesn't show any orange led for charging but it still charges...
    It won't turn on; I cannot hear any HDD spinning up noises or DVD drive sounds, and the power led isn't active, at all.
    I don't mind testing the HDD, since I have all the tools and a SATA 2.5 inch caddy at hand.
    So, any suggestions on what the issue is?
    Thanks

    Update:

    Update:
    I managed to get it on for 3 secs with the battery in, i heard the boot sound and then it shut off, no screen backlight or picture though.
    It was only on for 3 secs.
    Maybe it is a battery issue?
    The battery has been charging for 1 hour and after taking it out and pressing the button, it has died.
    I think its the battery...
    Anyone else have a conclusion?

    Perhaps it's not charging? You stated it is still charging...how have you determined that?

    Thanks for the reply.
    I know because of this:
    Everytime I take out the battery, I press the button.
    It flashes for a few seconds. And then it doesnt flash again.
    It will only start flashing again when I put it back in and charge it...

    Unfortunately it sounds as if you have a non-user serviceable issue.

    Short of soldering, or in the case of liquid damage, cleaning, there isn't much to be done. Sometimes it is better to pull the plug on a part rather than repair it and send it to the big iCloud in the sky!

    You can try to reball the logic board... It's expensive, but you can send the logic board out to a BGA rework facility. They could desolder the CPU, GPU, and northbridge, reball the parts, then solder them back on.

    Of course, it would be cheaper to just buy a new logic board.

    A big thanks to all of you guys who replied. I managed to get it working again.
    Turns out, it was the charger port. It would only work if bent slightly. And the battery was totally dead too.
    I left it bent and taped at an angle overnight and it is fully working now.
    Thanks again guys for the help.

    Glad to hear it's working again, those aren't bad machines. What are the specs?

    A new DC in board isn't hard to do. It is a relatively affordable part too!

    That is my first suspect on all iBooks (2004-05) that don't turn on. About 90% of the time that's what it is.

    [solved]

    lol, reco2011 FTW - sorry forgot to mention you in last post...

    Specs?
    They are kinda just stock at the moment:
    1.33GHz PowerPC iBook G4 (12 inch)
    40GB HDD
    512MB RAM

    Anyway, now it's almost fully working, I am creating another thread for an OS X issue i have. If you guys could help, that'd be great!
    Thanks.

    Would you mind moving a resistor on the logic board? I want to test some overclocking settings, and I need a machine to test on.

    Really?
    What RAM type is it?
    (new to mac upgrades)
    And what's the RAM limit?

    (PS thanks for responding to the other post)

    It was sorta a joke :D
    I just got to the conversation later than you did, and since he directly quoted me I felt I had to reply not to be rude. Thus I used your answer. :D:):D
