IBook won't boot up after a rest..

I hava the most weird problem with my iBook..
As I have it running, it works just fine.
I can boot it up, install software and do all sorts of things with it but when I turn it off and let it stay like that for like couple of hours, it won't boot up no more.
With the OS disk I can revive it, just now it took 5 tries, but it started and now as I shut it down and turn it on again there is no problem. But yet again, if I let it stand there for a hour or two, we are back in with the same problem, it won't finf the boot disk and needs to be revived with the OS intallation disk.
I reinstalled the whole (clean install) system today, had everything set up and installed all my software and such and there was no problem during the whole day, but now I had it turned off for few hours, it's just the same..
What might be the problem??

Now there is a new HD and it works better than this iBook has ever done.
That's great! Glad that resolved your issue.
So, problem solved, not in a conventional way but solved.
Well, actually, pretty conventional. The average life of an internal HDD in a laptop is approximately 3 to 5 years, and even if they survive beyond that they can fail suddenly or else continue with progressively degraded performance until they expire. The new HDDs have larger capacities and faster rotational speeds, both of which significantly boost performance.
Good luck.

Help! iBook won't boot up after latest security upgrade....................

I have an iBook G4 12 inch screen mac. I have recently updated with the latest Apple security update (15/9/08)Since installing the update my iBook has failed to boot up successfully. There is no start-up chime and the boot stops at the grey screen with the Apple logo and goes no further. I have tried safe mode, won't go there, have tried various other tips, holding down various keys on start-up, all with no joy! Does anyone have the same problem and does anyone have any answers?! Thanks in advance!
Jim

Thanks, Cornelius. I am just afraid now, is it safe or should I forget about reinstalling the most recent update? It is moot right now though anyway, because I still can't get my computer to fully boot up. At least attempting to book with the OS 10.5 disc in the drive it does not power down, but it is getting stuck for a long time (over 30 minutes) on the gray startup screen with the apple and the DVD drive repeatedly spins and stops, then finally just seems to stop spinning and gives up.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

Mac OSx won't boot up after update to 10.6.7?

Mac OSx won't boot up after update to 10.6.7?

Hi Mike
This is called a kernel panic, similar to s 'blue screen of death' on Windows. When you say you reinstalled 3 times, do you mean the OS or the Update?
When does this kernel panic appear? You may have a hardware issue if it's happening on boot.

IBook won't boot from CD

I bought this iBook, used, with Tiger on it. A while back, it had Debian Lenny installed onto it. Now I can't reinstall Tiger...
I have tried holding "C" before the gray screen when it boots, and I've tried holding "option". It only shows the disk with the Linux penguin, but not my Tiger install CD. Holding C, it only loops trying to read the CD; it does NOT reboot, it just unsuccessfully continues attempting to read the disk.
I know it not be a problem with my CD, because I can't reinstall Debian or Kubuntu or Ubuntu, even from the disk used in the past. I have tried resetting the PRAM and PMU..
Is there any hope?? I'm done with using Linux.

Yes, the iMac will still boot from the CD. The iBook won't boot from any disk anymore, not even retail Panther. I know that the CD drive still works, because I'm using it right now to listen to music in Debian.. I think something's up with the open firmware, and I should update it but that can only be done through Classic right? There's not even an update for my iBook, I think.
I've tried burning several different linix distros, and they all work with my iMac but not iBook.
And, yes, it is a set of four CDs for Tiger.

Clamshell iBook Won't Boot from Jaguar CD (v10.2.3)

Branching off from a prior thread (https://discussions.apple.com/message/13222609#13222609) in which booting from an OS X CD was a potential solution to a problem, the problem encountered with the potential solution warrants its own thread.
My machine is a Clamshell iBook (G3), Revision B (with 64MB base RAM and no FireWire). It was purchased new eleven years ago and later ugpraded to 192MB RAM.
The OS on the hard drive was 9.0.2 until yesterday, when I updated it to 9.1 so I could bring the firmware up to date. I did this before attempting to use the Jaguar CD.
The CD in question is an original Jaguar install CD, version 10.2.3. This is a two-disc set (the discs are labeled 1 and 2) and is a retail version; my iBook was manufactured prior to the release of OS X (non-server) and does not have an OEM OS X disc.
When the iBook attempts to boot from the CD, either by pressing "C" at startup or by running the Installer from OS 9.1, it seems to be loading fine until the following appears:
At this point, the iBook won't load any further and a restart is required.
The iBook does boot an OS X Cheetah (10.0) CD as well as its own restore disc (9.0.2) and the 9.1 disc that came with Cheetah. Unfortunately, Cheetah doesn't seem to have any effect on the battery (this is why I'm booting with an OS X CD; see the posts in the other thread for details). I don't have any other retail CD versions of OS X to try (aside from a Snow Leopard DVD).
Aside from this boot problem and the battery issue (the computer won't recognize the battery and displays an "X" through it even after having charged it with an external charger) the iBook is working perfectly fine.

No. I get the "X" through the battery in the menu bar and no bars, just a plug icon, in the control strip under OS 9.
The battery is a year old and has never been recognized by this computer. I don't have another Clamshell to test it in but did verify that it can charge in a VST charger.
The last time the computer recognized a battery was about 6 years ago when the initial batteries were still in use. Both were completely depleted after my charger shorted out; they didn't charge again after I got a new charger. The batteries were healthy at the time and were able to hold 3-4 hours, which was pretty typical mileage for me on this laptop.

Ibook won't boot up on own or from OS installation CD (need help in Yemen)

Hello,
I'm currently in Yemen for a few months and my ibook seems to have died on me. The country isn't exactly brimming with Apple support technicians so any advice or suggestions people could give me would be really appreciated.
I have an older ibook (dual USB G3 which I bought in June 2001). It has the occasional application or OS freezes, but typically restarting solves these. Yesterday, however, when I tried restarting the computer wouldn't boot up - it would get to the gray start up screen with the apple and spinning wheel and would just sit there with no progress even after an hour. I removed the airport card and extra RAM, but no luck.
I ran the Apple Hardware Check CD, but everything came up clean. I also ran Norton Utilities Disk Warrier and it found Major Errors in some of the directories (I have the list at home if that would help) all of which it said it fixed. However, it wasn't able to complete checking the HD, at one point it tried to find some files and never was able to get any further in the check - it would just sit for hours with no progress. When I tried rebooting the computer on its own it got no further than a gray screen.
At this point I decided it might be easiest just to reinstall the opperating system. I put in the installation disks (OS 10.2.4) and tried booting up from the CD - the boot up was very slow and ultimately (maybe after 10 minutes) instead of a gray screen with an Apple logo it came up with the "forbidden symbol" (i.e. the circle with the slash through it that you see on no smoking signs).
At this point I'm not quite sure what to since it isn't booting up from the installation CD - are there any other tricks I could try or reason why it won't boot up from the CD? I also have a copy of 10.4 installation CD but I'm hesitant to install it just because the ibook is such an old computer and it would require the extra RAM to run it (currently I have 300 something of RAM in the computer). I also have a 20 GB external harddrive with me if there's anyway I could boot up with it.
Three years ago the laptop had major problems and basically died, but went into Apple and seemed to have been fixed and had the logic board replaced. After this point I got a new laptop (which I'm hiting myself for not bringing with me at this point) and haven't really used this computer frequently - maybe 5 to 10 times in the last 3 years, it really is a "spare" laptop. I used it for about a week before coming and it seemed to be working fine.
At this point I'm really open to any suggestions on how to fix and jury rig it to work for the next 3 months (really I just need to be able to use Word and iPhoto) or so as I won't be using it once I get back to the States. Any suggestions or help would be greatly appreciate. Thank you very much!!

Hi, and welcome to Apple Discussions.
Which utility did you use on the iBook? Was it Norton DiskDoctor or Alsoft's DiskWarrior? They are two entirely different things.
Norton DiskDoctor was developed for OS 9. It doesn't recognize OS X as a legitimate operating system, identifies OS X as "errors" on your drive, and sets about "fixing" those errors, really messing things up in the process. (It does this even if you run it in OS 9 on a drive that has OS X on it.)
Apple calls the sign you are seeing when trying to boot from the CD a "prohibitory sign."
Check out this Apple Knowledge Base article on what to do about a prohibitory sign at startup:
http://docs.info.apple.com/article.html?artnum=106805
Maybe something there will help.

Tangerine iBook won't boot

My cousin has a Tangerine iBook, and she noticed today that it won't boot. She says the power indicator light ring around the power port isn't lighting up anymore, so I am guessing fried motherboard or the power adapter has gone bad. Does this make sense or are there other things I should be looking for? Thanks!

Try a different power adapter. Maybe one of your friends has a clamshell or a black G3 PowerBook.
It is a known issue that the cable connection between the yoyo power adapter near the plug breaks easily after some years of use - so don't give up too soon.
Next thing would be the DC-in board.
http://www.ifixit.com/Guide/Mac/iBook-G3-Clamshell/DC-In-Board/49/12/Page-1
When the plug goes in and out a thousand times it looses its contact and needs to be resoldered.
Sometimes the DC-in board is fried and the logicboard is still working.

Computer won't boot up after installing SIIG card

Hey Everyone,
I having problems with my SIIG FireWire 2-Port PCIe DV card that I've installed into my PowerMac G5 Quad. With the card installed the computer will not boot up, which is the same thing that happened with my previous two models of the card. I installed a new card yesterday and it worked fine all day, but after shutting the computer down for the night and then restarting it in the morning I am experiencing the same problems. The light on the front of the computer turns on, but the screen does not, and after about a minute a loud fan noise comes one. I have the card installed in Slot 2. In Slot 1 I have a ProTools HD card and in Slot 3 I have an AJA Kona LHE card. Even with all of the cards removed the computer still does not boot up. Anyone seen this problem before? Any help or information anybody can offer would be greatly appreciated.
PowerMac G5 Quad Mac OS X (10.4.8)

Hi, I had the same problem with my dual core G5.
I installed the card and my computer won't boot up. The screen stays gray and the fan keeps spinning.
I contacted SIIG and they said the card is defective, which, I doubt it is.
I then returned it for a refund.

Won't boot anymore after nvidia-xconfig

Hey Guys,
Got a problem with my Arch Linux here, hope you can help.
Today I tried to install the official Nvidia Driver and BumbleBee following along the great Wiki on this topic.
Everything worked just fine and I also could run optirun gfxgear or somemthing like this.
I wanted to switch to the Nvidia Settings in the settings menu and it told me to configure my xconfig and restart x so I typed nvidia-xconfig in the terminal and it gave me an success output.
I restarted my system and now it hangs on the graphical thing I think. It won't boot anymore.
Hope you can help me out.
Thanks alot
Edit: My Nvidia Card is a Nvidia GT 740M if this matters

No, I have a laptop with 2 graphic cards an intel hd4000 and a nvidia gt 740m.
I ran the Arch Linux installation well until I tried to get the nvidia gt working with bumblebee.
I followed the wiki of the bumblebee topic and it worked well. I wanted to switch into the nvidia settings and it told me my x isnt configured properly and I should type nvidia-xconfig and restart X.
After the restart it won't boot to the graphical interface anymore.
Hope this cleared up the things
Also I dont get any errors but it just wont load..

IBook won't boot, stops at gray screen--HELP

I couldn't find this exact topic at first glance and I am hoping someone can help me. My ibook is about 5 years old and has only really crashed on my once 2 years ago but I was able to reinstall the OS and go on my way. This time, however, nothing works. I tried to boot up yesterday and the gray screen appeared and that was it along with a strange buzzing sound. I tried Disk Warrior, wouldn't even boot off that. Also tried booting off system disk 1 and didn't get past the language screen, just hung up with that buzz again.
Does this sound like a logic board issue? Can it be rescued?
Thanks in advance for any help!

I'm not sure if the computer can be checked out at home in such a way
in its present state, to see if there is a logic board failure behind it, now,
or not. There could be a hard disk drive failure, or ATA controller failure;
and a short list of other possibilities, best checked over by a specialist.
Certain keyboard commands and things could be tried (and I usually
assume they'd been tried before asking here, but that's often not so)
just to see if one or more of them could get a rise out of the dead Mac.
Be sure, if you can get the installer disc to boot the Mac, that you
try and use the Disk Utility to repair disc; maybe more than once;
and do not try to just reinstall an Archive and Install. The HDD may
have corruption issues and it may need low-level zero-data and re-
formatting before a new system could go on there, if it worked at all.
{Even trying to reset PRAM/NVRAM and then seeing if you can get
the bootable OSX installer disc to start up the Mac could be OK.
Maybe that PMU reset, as a last resort? It probably won't hurt...}
A system on an external bootable enclosed hard disk drive could be
used by a tech or a prepared home-tech owner, and a clone of the
machine's system then attempted to be used to boot the ailing Mac.
If the optical drive and other components relying on the logic board
are dysfunctional due to a defect on that main board, most external
devices may also have a hard time trying to use these methods of
outside efforts to troubleshoot be nominally successful.
There may be a way a tech can use an second computer to get
data off the drive in your iBook, should it come to that, by using
the FireWire Target Disk mode and see if your iBook can start
and act like an external hard disk drive. A copy of the drive's
content or parts of it may be made by the second healthy Mac.
A clone (perhaps not bootable if data on it is damaged and not
recoverable) could be made if the second healthy computer has
a clone utility and also an external drive it can copy/clone the
iBook's drive content over to. This may be asking too much;
but the home user who has stuff on hand could do it shortly.
Anyway, there are some ideas online, if you can search google
and choose appropriate words; I looked but you may need to
read through several different source links to see if anything
sounds like it may work. re: iBook won't start past grey screen
Some users have tried resetting the PMU, others tried NVRAM
and PRAM; a few tried SafeBoot to see if the system was OK
enough to load in a reduced startup mode; maybe where the
system's own Disk Utility could be ran to at least fix permissions.
And of these, if it is truly a logic board or a failed hard disk drive,
they won't really do much. Probably no harm; and that is part
of what troubleshooting is all about, working with zeros and ones!
Good luck & happy computing!
edited to add a chapter.

Dropped iBook - won't boot up, help!

Because I'm an idiot, I dropped my beloved G4 iBook on the ground and now it won't boot up. I can get it to turn on, I get the startup chime, it gets to the blue screen with the grey Apple and spinning progress indicator...and that's it. The spinning disc just keeps on spinning indefinitely. No error messages, no kernel panic, nothing like that. Tried booting in Safe Mode...get the blue screen with grey apple, no spinning disc, and that's as far as I can get.
I bought it secondhand from a friend so no warranty or Applecare or anything like that. Is the hard drive okay? Could something have come loose and just needs to be snapped back into place? Did the motherboard get cracked? What could cause this type of problem, especially since I can't even get it to boot in Safe Mode, and what can I do to fix it? Is it even fixable? Have I lost all my files? Can I just take it to a repair shop and everything will be okay?!?!
helllllllp!!!! :'(

Hi from another idiot iMac user (I last posted when I spilled a glass of water on my desktop's keyboard...)
I dropped my iBook G4 on the stairs this morning Since it sort of slid down the carpeting I thought I'd be OK but it was just like the other used described - Apple logo, spinning startup icon, a few clicks and whirrs then nothing.
I followed your instructions below, and the Installer loaded. I have clicked on Introduction, agreed with the licensing, selected a destination (clicked on HD), but then I got a message "You cannot install Mac OS X on this volume without changing your install settings. Click Options to change settings. A newer version of Mac OS is installed."
I never got a Repair Disk button. I never installed newer software, unless it was an update that downloaded from Apple. What should I do?
Thanks!!!!

Btrfs: System won't boot anymore after unclean shutdown

Hi,
I have a problem with my ArchLinux (kernel 3.19.2-1-ARCH).
I have my root partition as BTRFS and no /boot partition.
After an unclean shutdown the system won't boot anymore.
GRUB loads the kernel and the kernel starts but it hangs saying: Mounted /dev/sda3 on real root.
Then, I have to start a Live CD and do:
btrfsck /dev/sda3
After that the system boots correctly.
I've tried adding fsck to the HOOKS in the mkinitcpio.conf file and in fact it tries to fsck the filesystem (but with BTRFS, fsck.btrfs doesn't work...)
What can I do?
Thanks

I'm also having this problem. I tried booting up the netinstall image to debug it, but I can't mount my btrfs volume from there either: mount just hangs. After a while, the kernel goes:
[...] INFO: task mount:612 blocked for more than 120 seconds.
[...] Not tainted 3.19.2-1-ARCH #1
[...] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
[...] INFO: task btrfs-transacti:636 blocked for more than 120 seconds.
[...] Not tainted 3.19.2-1-ARCH #1
[...] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
From this post I guessed that I might just need to wait so that I could defrag the volume once it was mounted, but it's been hanging for over 15min now (the message above continues to come up periodically).
Like the OP in the thread I linked to above, my btrfs volume is inside an LVM volume (which is on dm-crypt). Don't know whether that's relevant.

MacBook Pro won't boot up after Lion upgrade

I upgraded my 13" macbook pro to lion last night. I watched some movies until the battiery died. Now it won't boot up. Indicator light does not come on and it makes no noise. Battery indicator says it's full. Any suggestions?

MBP's are very finicky about RAM. Most of us here will recommend Crucial or OWC as the best source. If I were you I'd put the original RAM back in and see if the problem goes away. If so, return what you just bought and buy from one of the vendors I mentioned.

IBook won't boot up after a rest..
