IBook G4 Blue Screen

Since this problem seems to have happened with most people here, as a result of an Apple software update, Apple should be responsible to help us solve this problem. It is their responsibility. ... They broke it, They bought it.
Has anybody gotten through to Apple regarding this mess?? Has anybody found a solution?

There probably are variants, as well as alternative cause scenarios
and their resultant troubleshooting and repair procedures....

Re: ibook g4 blue screen

I am having trouble loading my ibook g4 since a friend held command S and then changed some info on the page that came up, now it only goes to blue screen and stays there, is there a way to reset the computer to factory specs????

Hey! Did you ever figure any of this out, I have had this problem for a few years, every once in a while attempting to fix it. Please let me know, thanks and good luck to you!

I am using ibook G4 PPC with mac os x10.4.11. A day before I delete one file from my hard disk by mistake and after that when I restarted my notebook, it's not starting the os. Only that blue screen is there. please, show me how to deal with it.

I am using an old ibook G4 ppc with mac os x 10.4.11. A day before by default I delete one file and I think it was the startup file of os because after that when I restarted my notebook it's not running the OS only that blue screen is there. This notebook was a gift for me and still it is so close to my heart. I don't wana loose it. Please, help me out.

Without the install CD, you are hosed.
What happened to it?
It is possible to call AppleCare and order a replacement. They will charge you a nominal fee for shipping and handling.

G4 iBook works in Safe Mode, but not in regular mode (stuck on blue screen)

14" iBook G4 1.2GHz with 1 gig of RAM.
I recently had an issue with this machine in that the image on the screen would freeze but the cursor would be able to move around. This was narrowed down to an issue with the logic board. I wanted something a little more permanent than a shim, so I sent the board in to have it reballed.
After installing the maching back into my iBook, it seemed to work fine until I applied a software update to the machine.
It was then that I got to experience the first of many kernel panics.
Restarting at different times always brought me to the dialog box which states that the machine needed to be restarted in multiple languages.
Running the Apple Hardware Test off my install disks yielded this error code: 2ATI/2/4:113-xxxxx-125
I have no idea what that means. I do know that just before I got the results of the test, the screen changed to all kinds of colors. It was only for a few seconds and then the results (with the error code) were displayed.
Still, not sure what to do next, I tried resetting the PRAM. I also tried resetting the NVRAM.
I also tried booting up into Safe Mode which actually worked. There were no issues with the machine and everything seemed to be working fine.
When I tried to restart the machine in regular mode, I'm taken to the infamous blue screen and the machine just stays there. When I let the machine stay off overnight, it booted up normal, but after applying the software update, the machine was in kernel panic again.
I've tried running fsck, but nothing changes.
I'm still not sure why it seems to work in Safe Mode but not in regular mode.
I'd appreciate any suggestions or ideas.

Hi,
A couple of the things that are disabled in safe mode are AirPort and non Apple startup items. The easiest thing for you to test is the AirPort card. Shut down and remove the AE card under the keyboard. See if it starts. If it does your AE card is bad. If not, start in safe mode and go to System Preferences>Accounts>youraccount and disable all non Apple startup (LOgin) items by clicking on them and then the minus sign. Restart normally and see if it will start.

Ibook G4 freezes either when its on the grey loading screen or the blue screen. Sometimes I get it to my desktop but it always freezes in like a minute. Someone help I really need this computer!

I have tried everything online and my iBook g4 wont stop freezing. Safe Mode doesnt even help, it still gets stuck on the blue screen! It either gets stuck on the grey loading screen or the blue screen. Rarely I am able to boot past everything and get to my desktop but after about 30 seconds it freezes again. This laptop was passed down to me and I have no original papers or disks that came with this laptop. I am really trying to figure this out without buying a disk because if it doesnt work I wont be out $60. Someone help I have tried putting it in safe mode single mode holding c down during start up! I need more options.. Please this is the only computer I have right now! (PS: I know warranty has expired a long long time ago)

IBook G4 Freezes at Startup Window or gives Blank Blue Screen

Ok, so I realize my description is long, but I've been going through these forums gleaning off the wisdom of the past...and so here's what I've tried
Description of Problem:
1. Computer froze, had to be shut down by holding down power button
2. On restart, goes to apple pages with status wheel (looks like turning gear). But then either freezes on that page, or more frequently goes to a blank light blue screen.
3. Tried restarting from install CD, ends in blank light blue screen.
4. Restarted holding option, tried to restart from a firewire clone of the drive, ends in blank light blue screen.
5. DId a reset to firmware, typed in two lines of code as found on discussion board, it restarted, no effect.
TARGET FIREWIRE
Opened computer as target firewire drive
6. used disk utility to repair, there was nothing to repair.
7. Used DiskWarrior to rebuild.
8. Backed up drive using superduper
UNMOUNTED FIREWIRE
9. No change
HELP???? This computer is NOT under AppleCare anymore.

This EXACT thing has just happened to me!
It is a 12 inch ibook G4.
I am hoping it will come back up one more time so that I can transfer it to a Terra server I have here in the lab.
I am wondering what I am going to do...

Help! blue screen of death and ibook won't boot at all

I ran the software update on my ibook (800 mhz, G3 running 10.4.3) today. I repaired permissions and rebooted before hand. I don't have any hacks on it. I have plently of room on the drive for the update (more than 6gigs on the 30 gig drive). I know my ibook is feeling its age, but now she won't start at all!
When I ran the update (which I already did on my imac with no problems), the ipod updater, quicktime and something else installed without problem. I came into the room to find that the Mac OS 10.4.4 updater had a red exclimation point next to it, and I had an error message that there was a problem with the update and that I needed to reboot. Restarting was my only option so I did. ibook would not start. It hung on the "starting OS X" screen forever (45 minutes). I force-restarted and booted in single-user mode. I have an app called AppleJack installed so I ran that (repairs permissions and such in single-user mode). I rebooted. Nothing. Blue screen of death.
Any ideas? Should I reinstall OS 10.4 from the CD?

How is mail different than that?
Mail keeps mailboxes in their own separate Finder files.
Home -> Library -> Mail
Home -> Library -> Mail Downloads
Notice also that Mailboxes themselves have their own folders in
Home -> Library -> Mail -> Mailboxes
Addressbook keeps addresses for Mail in its own set of Finder Files.
Home -> Library -> Application Support -> Addressbook
iCal keeps it in
Home -> Library -> Calendars
Whereas Microsoft Office is simply everything in one user belongs to:
Home -> Documents -> Microsoft User Data -> Identities -> Main Identity -> Database
So in reality you have 4 different places, and simple data corruption inside the database file itself is not going to take out all of the data when you use Mail, Addressbook, and iCal. I find it is much more robust to use Mail, Addressbook, and iCal purely for the reason that data corruption is not as prevalent a problem when your database gets large.
Single user mode is not a good idea, until the data is actually backed up in some fashion. Once you are getting input/output errors, trying to get it out of a place where there is data corruption by using a data recovery program is the first step with Prosoft Data Rescue.
You may try to rebuild the database file too, which might work, but since your machine is suffering a lot of input/output errors, I'm suspicious of the health of your hard drive, and you are booting to a blue screen, single user mode may not be enough, even Disk Warrior may not be enough. Now's the time to get all the data off the hard drive into another in a safe place. Data Rescue may be able to recover it. If not, you may have to deal with a data recovery firm.

Ibook won't boot completely ! (stops at a blue screen)

Hi...first time poster here, please be kind. Also, I'm not brilliant by any measure when it to computers.
Yesterday I was installing updates (now, my ibook was out of use for at least 8 months, so I was bit back logged on updates) and after the second round (a safari update, a java update, and a security update) it said it needed to restart. Ok, easy enough, though apparently not it never booted up again. I get past the grey apple loading screen and to the blue screen that says "loading os x"...the progress bar finishes and then it disappears and all I get is a blue screen with a rotating "busy/working" symbol. A few times I got a black screen with white text asking for my login and password, but it always says it's wrong or it won't even let me type in a password before it freezes and goes on to the blue blank screen again. I did a PRAM cleaning and that ran correctly but did not help. It will not load in safe or verbose mode. Any one have any idea why my ibook is doing this or if there is anyway to fix it ? (also, I'm not sure eaxactly which os X I am running other than it os x 10.4) Help...

If you can't find the system discs that came with your computer, use fsck (a command-line utility that may be able to verify and repair a disk)
To use fsck:
1. Start up your computer in single-user mode to reach the command line.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

After Software update yesterday, ibook cannot reboot & stay in blue screen.

After yesterday software update, My ibook restart and got stuck in the blue screen with the spinning spiral icon in the middle of the screen.
I try to reset the pram and PMU but in vain.
I also use CRTL-V while rebooting and found the repeating last few lines which the command prompt shown was as follow:
localhost/system/library/coreservices/loginwindow.app/contents/MacOs/loginwindow s:Login Window Application Started
Anyone can assist, thanks in advance.

I only use Software Update to see what is needed, then get them for real via...
http://www.apple.com/support/downloads/
That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.

IBook G4 Freezes at Blue Screen During Startup.

iBook G4 933 MHz
Mac OS X 10.4. Tiger
640MB RAM
40GB internal ATA hard drive
Computer boots but then quickly locks up.
If I immediately restart, then the iBook hangs at the blue screen before the Mac OS X progress screen appears.
If I remove the battery and unplug the power cord then allow the computer to sit for at least 30 minutes, able to fully boot, but then the machine quickly freezes up.
I assume the problem is heat related?
I have so far:
- Totally disassembled/reassembled
- Reset PRAM
- Reset NVRAM
- Reset PMU
- Unable to do target disk mode
- iBook freezes same way when booting to Mac OS X install DVD
Able to boot to shell command line mode no problem.
FSCK reports no issues with the HDD.
Sometimes during startup a fan turns on briefly, but not every attempt to boot.
Yes-- I know about the 'solder' issues with iBook G4 logic boards, but I do not think the above is related. The VGA works fine.
Thanks for any assistance that can be rendered.

After a month, I have been notified by Superior Reball that the logic board has been repaired. I promptly made payment of $35 and the board was shipped back to me on June 17 via USPS Priority Mail Delivery Confirmation. I have received the tracking number and anticipate receiving the package by June 20.
In my situation, well worth the wait for only $35.
Even though I chose to totally disassemble the iBook, Superior will do the disassemble/reassemble for $75.
I would not have done it by shipping the entire iBook, though. With the higher shipping cost, insurance, having to send out the hard drive with no back up, the higher repair cost, etc.-- in the end a prohibitive expense. I could probably buy a used iBook G4 for no more than $200, to put things in perspective.
In summary, Superior Reball had a great price, good enough communication (they answer the phone, but not e-mail) and it looks like fast return shipping. It took a lot longer than the ad states, so I am applying the old 'price, speed, quality-- choose any two' rule here.

IBook G4 Incomplete Start-up / Post-Apple Icon Blue-screen

My brother's iBook G4 is acting strange and I've run a number of tests to sort the problem, none of which have yielded any useful results. This is a summary of what I've tried/seen:
• iBook was running 10.4.?? - not totally sure which version he had last updated - I suspect 10.4.9
• iBook starts to boot up, but after showing gray Apple logo and "load progress spinner" below
it then displays a blank blue-screen and sits there. No pointer, no loading - just sits
• His machine is Target-Mode access-able from my machine (MacBook Pro), and Target Mode symbol correctly appears and moves around the iBook screen. I was able to copy/archive his most important files just in case - though some picture files seemed to cause the transfer to hang
• *iBook seems unable or unwilling to boot off of OSX disk - no matter how many times we try. It doesn't appear to see it even when holding down 'C' at startup. The disk in his drive, however, shows up fine and readable on my desktop via Target-mode. Odd.*
• Running Disk Utility from my machine and looking at his drive in Target-mode reveals that his drive checks out 'OK'... however it doesn't appear to see a valid OS on the drive as options to "Verify/Repair Disk Permisions" are grayed out.
• Have reset PMU & PRAM successfully - and have run 'fsck', which says disk is fine.
I cannot think of what else the problem might be. He doesn't run any complicated/odd/non-standard software as his needs are simple. I would like to clean-install from his original disks, but see no way to do this as my machine does not allow me to boot from his older OS disks in order to do so by remote.
Any additional suggestions before considering the repair-shop? Much appreciated.
ant.

Welcome To  Discussions ant!
"My brother's iBook G4 is acting strange..."
Please post what the strange behavior is.
Exactly which model ibook G4 is it?
What size is the Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?
What happened between the last time the iBook functionmed properly, and when it didn't?
Had he made any changes, like upgrading the system, updated or installed any applications or programs, etc?
Have there been any unusual occurences, like freezes, crashes, power outages, etc?
"iBook seems unable or unwilling to boot off of OSX disk - no matter how many times we try."
Are you sure you are using the correct disc, for the iBook, and the installed version of OS X?
What version of OS is on the original system install disc, if that is not the disc you are using, and will the iBook start from that?
If you are using a disc other than the original, is it the Full Retail Version, of the Tiger Install DVD?

IBook G4 suddenly freezes, does not go beyond blue screen

My iBook G4, recently upgraded to 10.5.2, suddenly went into a freeze, where neither the mouse nor nothing else would move anymore. I had to shut down by pressing the power button. When starting anew, I did not get past the blue screen. Same problem when trying to start in Safe Mode. I managed to get past the blue screen twice, with long intervals in between start-ups (ie. starting from cool), but the machine immediately froze up again in the first 10 seconds. Since the machine had the same problems two years ago, I am suspecting the Logic Board (yet again), although the Board was exchanged by the Mac Service in 2006. I backed up all the data in Transfer Mode without problem, so the HD seems to be unaffected. I cannot start the iBook from the disc so cannot run TechTool or Disk Utility. Please help.

Thanks - none of these problems seem to refer to my own blue screen problem, which did not occur just after updating to 10.5 or 10.5.2 - I had the software running without problems for weeks now. So it must be something new coming up. I ran a hardware test on the machine, and no logic board or hard disk problem was found. So it seems to be something else. Without being able to start on the installation disk, I can't even do an archive and install.

IBook G4 won't start up, blue screen death! HELP!

I have an iBook G4 (1.2ghz). It has a new hard drive (5 months old), 2 gigs of ram (5 months old), and a new battery (2 months old). I was checking some baseball scores today, and everything froze, as if the hard drive had died. I tried to reboot, and it got stuck at a blue screen. I tried to reboot 4-5 times, and once it worked! I tried running my backup software, and it froze, without backing up my files. Since then, I have:
zapped the pram,
tried to start from a CD
tried to start up in safe mode
nothing gets me past the blue screen of death. I can't even fathom why it won't start from a CD. Is my computer dead? is the hard drive dead? what is let to do?

for those who come across this - and have similar issues - i have an ibook g4 - 14". I used the shim method described by http://www.coreyarnold.org/ibook/ . While he used this method on a 12", I used it on a 14", and it seems to have worked. The computer has been up and running for nearly 4 hours and everything has been backed up. I used 2 3/4" rubber gripping pads purchased at true value for less than $2. The tools cost me $25 from ifixit.com. Beats a reball, and certainly beats a $300 logic board replacement (not including labor!).

14" iBook won't boot past Blue Screen?

Hi,
I have in my possession my Sisters 14" iBook G4. It boots with the grey Apple logo but then freezes at the blue screen. I'm guessing it's either the hard drive or logic board, does anyone have a procedure to follow to diagnose the fault? I don't have the original discs but do have a 10.5 retail box.
Thanks in advance.

Spudnuty - I think you might want to hear this...
I just bought an ibook G4 1.2Ghz "Late 2004" model off of ebay, had the blue screen problem. I bought it because I thought it might have been the OS (freeze at login) and the previous owner didn't know, but it was an actual freeze... actually froze a few times while at the spinning wheel at startup, and would randomly display a dark blue screen sometimes at startup.
I am an ACMT, I decided to disassemble the machine as per the service manual and get it down to basically the logic board, even pulled off the top display entirely. Ran an external monitor via mini-VGA, external HD via Firewire... still froze at blue screen. So I decided something similar to your suggestion - I pulled off the heat sink, only to discover that the conventional way of cooling a cpu/gpu (heating compound directly under heat sink) had been abandoned on this model for some crappy adhesive pads. The pads had a bit of thickness to them, so I decided to cut of a small section of the top shield, fold it into a nice square and flatten it. I then put some heat sink compound on both the cpu and gpu, put the metal "shim" on the gpu and tightened down the heat sink. Guess what? Started up in a jiffy. I put a fresh install of Tiger on it, have been playing multiple Quicktime vids looped for a while now... machine is going strong.
All that to say, shimming works on these later ibook G4 models that get the blue screen, I've confirmed it. Just remove the adhesive pads, shim with something heat conductive (maybe even aluminum foil!), add heat compound and run it for a while.

IBook G3 will not start up-hangs up at blue screen

My IBook G3 will not start up. I can get the gray apple screen with pinwheel and then after a really long time it will go to a blank blue screen. A couple times it went to the login screen instead but in the user id it says "other" and when I try to enter my username and password it won't recognize me. I am a college student and one of the Apple geniuses here did a check of my hard drive and it checked out okay. We were not able to get it to start up in safe mode; it seemed like it was starting in safe mode but then it came to the login screen and would not allow me to login with my usual information. I was able to start up in single user mode and run fsck which found a couple things and after another fsck it said everthing was fine. But, it still gets hung up at startup. When I try to boot from the OS X installation CD it doesn't seem to be booting up with it, it only goes to the screen to install OS X. According to the directions on the Apple support site when I insert the CD and start up holding down the "c" key it should start up and then I should be able to repair permissions but I can't get that far.

Hi, and welcome to Apple Discussions.
To post a new topic when you are on a forum's topic list page, at the top left (under the word Forum), you will find a link to "Post New Topic." Click on that link, title your topic, and post in the box provided.
There are many things that can happen when you bounce an iBook off the floor.
It sounds like something may have been knocked loose, perhaps a connection? Probably it is going to take an analysis by a technician to tell you exactly what's going on. I have links for firms on both coasts, but you should be able to find an Apple Authorized Service Provider (or just someone who advertises that he/she works on Macs) in a metropolitan area like Chicago just by grabbing your Yellow Pages or local classifieds. I would think you would have a fairly competitive market there. Maybe you can find someone who does free diagnostics who will tell you what it will cost so you can decide whether its worth the cost to repair it.
Good luck.
