• Sudden boot problems, iBook G4

    From see_signature@see_signature@mac.com.invalid (Jon) to comp.sys.mac.hardware.misc,comp.sys.mac.system on Thursday, April 20, 2006 08:24:33
    From Newsgroup: comp.sys.mac.system

    Suddenly, my iBook G4 1.33 GHz (just out of warranty...) will not boot.
    It stops at the grey apple before the little carousel appears, or even a
    tad before, mostly not allowing me as far as a single-user boot so I can
    see what happens.

    It was running Tiger (10.4.6 w/latest updates) in 768 MB of RAM at the
    time this happened, and we can see no clear change that happened just
    before and that maight have a connection.

    The funny thing is, the disk spins and works. In Target mode, I got all
    the data off the disk, no sweat. I reinstalled Tiger on it via FW, doing
    a clean install w/format, given the circumstances. Both that _and_
    Migration Assistant ran without a hitch (MA both ways).

    It is worth noting, though, that the iBook also would not boot from the
    Tiger Install DVD, but that I had to connect to another Mac and run the Installer from there. However, that ran smoothly.

    However, once having a new OS installed, the same symptoms: No boot,
    only the disk spinning idly.

    Is it poossible that a repartitioning (slight shrinking) might eliminate
    bad (boot) blocks at the start of the default single partition, or is
    the disk simply a goner and should be replaced? Or are there other
    solutions compatible with the scenario, such as a bad disk controller or connection somewhere, or RAM gone bad (suddenly)?

    I'm stumped, and ideas are welcome! :-)
    TIA.

    It looks as if your PRAM is corrupted. Boot and press Alt-Opt-p-r until you hear the startup sound. Keep the four keys pressed until hear the startup sound a second and a third time. Then release the keys and see, whether your iBook will boot (might take a long time the first time afterwards).

    Alternatively, when you press Alt-V during boot, do you see anything interesting?

    That seemed to help in that the iBook then gets past the grey apple, but
    stops at the blue screen before the login window appears. I repeated,
    but got the same result.

    I tried taking all power from the computer for 30 minutes + resetting
    P-ram for good measure, but got the same result.

    Alternatively, when you press Alt-V during boot, do you see anything interesting?

    The last item before stop seems to be pretty consistent:
    "Login Window Applicaton started" *)

    *) Please remember that this is a completely fresh system install and
    that this happened both before and after that install, which makes it
    hard to believe that two copies of the same app in different versions
    (first the one from the 10.4.6 system and then the fresh 10.4.0 version)
    should be shot in both cases.

    After that it either stops, still in console mode, or goes on to the
    blue screen and then stops.

    I then tried to delete the loginwidow prefs by mounting the machine in
    Target mode, but that had no effect.

    I am running out of options here. And as you can gather, the FW Target
    mode still works without a hitch. Strange!

    To eliminate hardware as an issue, start the _other_ machine in Target
    Disk Mode, connect it to the failing iBook, and start the iBook while
    holding the Option key down. Select the other machine's disk and
    continue the startup.

    If you get the same class of failure, you have a non-disk related
    hardware failure.

    If everything is normal, something is wrong with the installation or configuration on the iBook. Attach the iBook in TDM and examine its log
    files for some clue.

    I have now even changed the disk and - again - reinstalled the system +
    again zapped PRAM. No effect, it still stalls in the boot process.

    I can also report that running the iBook in Target Disk mode, it will
    happily work as a boot volume for another Mac, so it seems more and more
    likely that it is _not_ the disk that is the problem, but some other
    component. The question, of course, is _what_ component, and can it be
    changed by me?

    Booting in Verbose mode, I still get to around "Login Window Application starting", then everything stops - if not a little before. And it is
    still impossible to boot from the internal DVD drive as well.

    Ideas? I am stumped...

    Will do - in fact, have done. Doesn't work, because I don't get far
    enough to select the other startup disk.

    hardware failure.

    That is what I am thinking now.

    I'll do that. Thanks.

    You might also try starting the iBook in OpenFirmware mode by holding Command-Option-O-F. If you get as far as a prompt, type
    reset-nvram (return)
    reset-all (return)

    The iBook should restart and maybe even boot. :-)

    Good luck.

    Do you have anything plugged into the USB or Firewire when this occurs?
    If so, and you remove it, does it boot?

    I ask because I had a USB hub that would totally hang my iMac, just as
    you describe your iBook doing. Just a thought.
