PowerBook G4 Dead

    I searched previous threads and I only got part of my issue addressed so I'm giving it a shot here.

    I just aquired a PowerBook G4 (500Mhz) and it is dead. It will not turn on no matter what I try and when I plug in the power adaptor it glows a bright orange (almost red)...what does that mean?

    Thanks! :) :apple:

    Do you mean you have a PowerBook G4?

    Oops..PowerBook. :eek: :apple:

    I thought so.

    It glows orange when it's charging the battery and green when it's charged.

    If you look at the battery there is a small button on it. If you push the button some little LEDs should light up.
    How many, if any, light up?

    EDIT: Not that that actually helps your problem. Sorry I got distracted. :eek:

    Do you know the history one it?

    I sometimes get a bulk amount of computer that I fix up to sell, use for spare part etc. etc. Sometimes I get them in with parts missing, do you know if everything is intact?

    I know a little of it's history....totally intact, had a minimal amount of usage, no hard or excess wear. It's been sitting unused for about 2 1/2 years.

    It's not a battery issue...I've already tried that. Now, as far as the orange light on the power adaptor, it's glowing bright orange..almost red, considerably more so than if it's plugged into my operating PowerBook G4.

    It could be the PRAM battery is dead. Although this should really stop it from starting up when connected to the mains. Does it make any noise at all when you push the power button?
  9. macrumors member


    Nope, no noise whatsoever. Totally dead.

    Maybe you have tried this already but try pressing the power button a little harder and hold it for about 2 seconds. It may just be a funky button. My iBook had a similar quirk.

    Have you checked to see if there is any ram in there? I know a lot of people take out all the RAM so they can sell it off for a bit more profit. There are quite a few pirates out there. :(

    It totally could stop it from booting. After sitting for 2.5 years there is a good chance the PRAM battery is toasted.

    I wasn't sure how critical to the startup process the battery is.
    My PowerBook G3 has a totally dead PRAM battery yet it still starts up from the mains.

    Thanks for the tips...tried the power button...no luck. It has RAM in it. I checked that earlier. Thanks again.

    Ok, so let's say that the PRAM battery is dead (sounds like that's what it is)how involved is the process of replacing it?

    Have a look on here:

    I know it's been a while, but I wanted to let you all know that it was the PRAM. After I changed it out, the computer booted up nicely. Thanks for all your help!
