Ibook not starting & "underlying task reported failure on exit"

My ibook is not starting up. It was having problems loading up and getting in interminable spinning ball fits as I tried to use the computer for basic things like surfing internet, word processing, itunes. I ran disk repair several times, and the problems would resume. Finally I left it on, afraid to turn it off, but my boyfriend unplugged it, and it eventually ran out of juice. Now I hear it power up, but it doesn't start up all the way (it's gotten to different points in start-up process after I took each step below, but never all the way).
What I've tried so far:
1. I've run disk repair from the start-up disk, and got the "The underlying task reported failure on exit" message.
2. I did the archive reinstall, did not work either. Tried disk repair again and still getting same message as #1.
3. Also tried starting up in single-user mode and running fsck, but getting message "root device is mounted read-only." Not sure what this means. Ran disk repair again after this, gets me same message as #1.
I'm hesitant to do a complete reinstall, as I have documents and music files that haven't been backed up. I have an external hard drive to move files if I could just start up my computer.
My questions:
1) Any thing else I can try short of complete reinstall to fix the problem?
2) Any way I can save my files if I can't get the computer fully loaded?
3) Would a 3rd-party disk repair program allow me to fix the problem without wiping out my files?
4) Why is fsck not running?
Any advice would be appreciated!
iBook G4 14 1.33GHz 768 RAM Mac OS X (10.3.9) Think it's 10.3.9, but can't verify. Bought ibook in '05.

Last question first, the command to shut down from Single-User Mode is:
shutdown now -h
Check out this Apple Knowledge Base article which addresses the exact problem you're seeing:
http://docs.info.apple.com/article.html?artnum=302411
DiskWarrior is likely your best bet for recovering your hard drive. Someone said it is available at Apple Stores, or you can use the online link I've provided here.
If you have another Mac, you may be able to access your hard drive via FireWire Target Disk Mode in order to retrieve your important files to the hard drive of the other Mac.
Good luck.

IBook not starting properly

My iBook is not starting properly. The machine begins normally: gray screen to blue and a bar filling from left to right, but it does not move past this point. I understand how to re-install OS X for example, but I am reluctant to do that when it seems the problem is only in getting the wheels spinning... Help! What do you suggest?

IBook not starting, fan going really fast

Hi everyone.
Yesterday something happened. Everytime I try to switch on my iBook G4, the power goes on, but the screen remains black and the fan starts to go really fast, like never happened before even when it was too hot. Yesterday I managed to hear the startup chime, and even once I managed to switch in on, but it lasted for around 10 minutes, and the the screen went black again.
Now I can only hear a sound, like a click (not the start up chime) and then the fan going fast, as I said, but nothing else happens.
Sorry for my English and thanx in advance for any help. It's much appreciated.
Regards.

Did you try booting off of Install disc #1 to see if you have video? If you can, it wouldn't hurt to navigate to Disk Utility and verify both permissions and the disk and repair if necessary. This probably won't solve the problem, but it is good practice to do before and after software updates.
If you can boot off of a CD, you could also try running the Apple Hardware Test and check for hardware problems. Very likely there won't be any that show up, but it will give you some assurance that your hardware has no major problems. The AHT won't find everything, but it does test quite a few things.
If you can boot from a CD, then you could consider doing an Archive and Install, as suggested in the article. It would be best to back up your data in advance if you can. If you have access to another Mac, you might be able to do this using Target Disk Mode. A fresh install of the OS will take care of any corrupted software, especially if it was caused by an update.
If reinstalling the OS does not fix the problem, then it is likely a hardware problem. But given what you have said here, it sounds more likely to be software.
good luck!

IBook not starting Mac OS

Hi, recently a customer bring me an iBook G4 12, the mac didnt start the MAc OS X.
The problem is this:
When the iBook starts it stays a lot in the Apple logo and round loading circle... afeter 10 or more minutes change to a blue screen without any on screen, finally after 10 or more minutes it change to the same blue screen but with the mouse pointer on it, whe I can move the mouse but no more else.
1. I dont have de software.
2. After trying the key SHIFT after the sound scheme y shutdowns after some minutes.
3. If I enter in single user (Apple key + S) and try some commands appears the next:
"/sbin/fsck -fy"
**/dev/rdisk0s3
**Root file system
**Checking HFS Plus volume
**Checking Extens Overflow file
**Checking Catalog file
Invalid node structure
(4, 1152)
**Volume check failed
4. If I try to mount the drive, it also sends an error:
"strategy err 0x5"
"I/O error"
5. If i put logout the ibook try to start but stops as the same problem, blue screen with mouse movement.
Thanks.

Hi there!
Sounds like the hard disk drive may be bad, or have bad sectors or file structures.
Perhaps a bootable disk tool (or the OS X installer which is bootable and has a
disk utility on it) would be necessary to hope to fix the errors on the drive; or to
be able to further study the problem to see if the hard disk drive may have failed.
Since the hard disk drives in iBook G4s are not so easy to exchange with a new
replacement, though that probably is a necessity, some users try to check and
repair the internal drive before replacing it. A tool such as Disk Warrior is helpful.
And any supported retail version of OS X the machine can use, in appropriate
disc media, should be able to start the computer (hold C on start) and be able to
use the Installer's Disk Utility to repair disk. That may not be enough; but you
can also verify disk to see if it passes the SMART test. Sometimes these do,
but still have issues requiring eventual replacement if they are well-used iBooks.
If you have a second Mac running OS X, you could see if the portable in question
could boot into FireWire Target Disk Mode, and then be seen as an external HDD.
With a FireWire cable, you may be able to see if the iBook's drive could be repaired
from a Disk Utility version in a host computer, so attached. (Use FW 6-pin to 6-pin.)
I have not tried this; so you may wish to check out the Support page for Target Disk
Mode, and other reading to see if there is a problem with this idea!
Good luck & happy computing!

Ibook not starting Mac OS X...keeps freezing up and asking to be rebooted

Hi,
Having trouble since I installed the latest OSX Update in that the iBook G4 gets to the opening gray screen (with the spinning wheel) and then feezes with a message saying "You need to restart your computer. Hold down the Saturday, Power button for several seconds or press the Restart button."
Restarting or rebooting does not help. Neither does trying to boot up in Safe Mode. Neither does running fsck seem to do anything (it runs but says that the HD is ok).
I'm a little screwed because I left my OSX disk and other software on CD-Rom at home in Canada while I'm on an extended stay in Europe. In other words I don't have the disk to run Disk Utility from startup. Any suggestions? Can I download anything on another computer, and burn a startup disk of some sort. Or do I need to get somebody to break into my apartment and mail me over the disks? Or am I beyond repair and have to take her in to a German reseller for service?
iBook G4 Mac OS X (10.4.3)

An Apple Authorized Service Provider in Europe should be able to help you out with the correct install disks for your iBook. They may charge you to help out, though... Without some troubleshooting using your disks, it might be difficult to figure out what's wrong with your iBook.

IBook is not starting up - "still waiting for root device"

The 600 MHz / 640 MB / 20 GB iBook did not want to wake up and after forced shutdown would not start up. grey screen. With MacOS X CD - "prohibition sign", MacOs 9 - no start at all
I had 2 partitions on the HD one with Tiger and other with 9.2.2 - none of them appear in the list of startUp folders. would not go into the Target mode.
I know there are few threads here with similar problem - I went through them but nothing of the suggestions would help.
Did reset the PRAM (only once though) - when I still heard the startUp chime
Did reset PMU
Left the machine unplugged for about 12 hours
Now I managed to get into single user mode while attempting to start up from a Tiger DVD. Here is what I see on the screen:
"using 1638 buffer headers and 1638 cluster IO headers
Extension "com.apple.driver.AppleTexas2Audio" has no kernel dependency.
(then there are 14 extensions listed that has no kernel dependency)

also I did not hear start up sound anymore. Yesterday it was still audible.... can someone please help?!
iBook dual USB Mac OS X (10.4.5)

thanx for replying. Last night I finally managed to start up the machine using a FireWire ext HD as a StartUp Disk. Disk Utility and TechTool Pro and Disk Warrior are not showing the internal HD at all.
Since I was not able to use any start CDs including original MacOs X and 9 Cds maybe it is a problem with Data Cable that connects both HD and optical drive with logic board? It is hard to imagine why it would come to something like that. Overheat? I did not have enough free space on Tiger partition - 1GB. Maybe that. I am starting to look for a replacement HD....

IBook will not start up!

My iBook will not start up all the way. It gets to the gray apple screen and just spins.(3hrs) I tried everything. It will not start up with 10.3 CD or OS9. It will start up with nortons CD but you cant see the Hard Drive. Hardware test CD starts and every thing checks out fine. What to do. I hope its not its final day.

Paul,
Do you have OS X 10.3 installed on it?
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, and repair permissions on it.
See if you are able to do a little hard drive maintenance to helps things out.
If it won't start up in Safe Mode, you can try Single User Mode and fsck, but if Safe Mode won't do it for you, fsck may not, either.
Keep Norton far, far away from any hard drive with OS X installed on it. DiskDoctor is known as DiskDoctor Kevorkian around here. It finds non-existent "errors" and sets about "correcting," them, killing your hard drive in the process.
If none of Apple's own disk repair procedures work (Safe Mode, Disk Utility from the Install disc, or fsck), it may be wise to invest in DiskWarrior. It can often find your hard drive and repair it when Apple's own utilities cannot. DiskWarrior has saved my hard drive more than once.
Good luck.

IBook will not start up - solid black screen

I am in love with my iBook and have not had a single problem with it the first sixteen months I had it. This morning I was using it and everything was fine, I put it to sleep, then it fell from a desk onto my foot. It fell at an angle, but my foot broke the fall. After that it does not start up, but remains in a solid black screen. The caps lock and number lock lights change when the appropriate buttons are pushed, but the power button does nothing, there is no sound, no fan, nothing.
When the battery is in, the power cord light is amber, but when I remove the battery, it goes to green. I have tried starting with the battery in and without it. The computer is slightly warm on the bottom. Also, the four lights on the battery are constantly lit, which I never noticed before.
Naturally I created an iMovie for a Christmas gift that I have not yet burned, so I want to resolve this asap.
Please offer suggestions! I'm not the most technically minded person, so layman's terms would be much appreciated. I looked through 20some pages of posts, but none of the suggestions seemed to help.
I do have the disks that came with the computer, but when I tried to insert a dvd, the computer would not even accept it all the way and did nothing to respond.
Thanks for any suggestions!

Cricket419,
Welcome to the forum.
I was told I can never buy one. Ever. Nice customer service there. I'm sure they know the majority of the warranties are never used, so I was offering pure profit for basically nothing on their part. As much as I love my computer, I'll think twice next time if this is how they respond to customers' requests to purchase additional items.
On the other hand; the flip-side of the coin as it were, there's this post from someone with a totally opposite experience from you:
http://discussions.apple.com/message.jspa?messageID=1348953#1348953
Specifically the following, from The TKDKid:
He spoke to the store manager, who authorized an exchange for a brand new one. They asked me if I could leave it for a couple of hours, and transferred all my files and personal settings to the new one. I was very pleased with the service I got.
I'm glad that your iBook is working again. With regards to AppleCare we all have 1 year from the date of purchase to buy it. It's up to us to decide and to remember to buy AppleCare during this period should we choose to do so. If we forget, then it's our fault and we have to own the fact that it's our fault, accept it and move on. It's not Apple's responsibily or fault.
If you have Home Contents Insurance then an option for you is to add the iBook to the items covered. Some (most?) home contents insurances automatically include repairs/replacement to computer damage (including any damage caused by accident). That would solve your cover queries. Wouldn't it?

IBook will not start up past gray screen w/ apple logo

iBook will not start up past gray screen w/ apple logo. So I have zeroed out the hard drive and reinstalled tiger. No change except if I start up holding shift it will boot and welcome comes up then black screen that says you must restart by holding down power key.
Zeroed out the HD again with same results. Also I have a iBook G3 with the same symptoms.

What you are experiencing is a kernel panic.
Try starting up from the Mac OS X Install Disc by inserting the disc and restarting your computer, holding down the C key as the startup chime is ending. Then choose Installer > Open Disk Utility (in Panther) or (in Tiger) click 'Next' at the language screen and choose Utilities > Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with the Install disc's Disk Utility, then try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if a little hard drive maintenance helps things out.

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.

IBook app, does not start !

Hi
The iBook app does not start !
I can't get into the library, it takes a minute at the gray background without shelfs, and then goes out.
I tried somethings like:
-remove books by iTunes and re sync them.
-reset the phone
-turning off and on the phone
but still have problem.

Howdy Safa,
If you are having an issue with your iPhone's iBooks application not being able to launch, and you have already tried resetting and restarting the iPhone, I would suggest the next step would be to back up any data on your iPhone and restore it as a new device. See this article for directions -
How to erase your iOS device and then set it up as a new device or restore it from backups
Thanks for using Apple Support Communities.
Best,

My IBOOK has shut down, and will not start back up

ok here is what has happened. yesterday my 1.2ghz g4 ibook started randomly shutting down. it would shut down and it would take a while of me pushing the power button to get it to start back up. when it would come on, it would switch between charging and not charged quite rapidly even though my power cord was in. now however, it has shut down and will not start up. the battery is fully charged. anyone have any ideas?

I'm telling you. I have lost all faith with Apple. The old iBook I had, 800MHz G4, simply worked fine with no problem waking up or starting up, although it's just a bit slow. Now, I am super frustrated when it just couldn't wake up, either with the sleep light flashing or not, ie it's black screen initially and when I press the Power button once to get it back to life, it just stays black!!!
So the only thing to do is to force power down by pressing the Power button for 10 seconds. Then I press the Power button once to start up, but it just stays black screen. I've left my iBook in that state for a day now, hoping that it will come back alife. But no! And the worst is, I had a similar problem starting up from wake just the day before. I called the Help Desk and they advised me step by step, from taking out the battery, to pressing OptionsCommand+PR, and OptionsCommand+OC, and doing Apple Hardware Test. The iBook seems to just work fine while on the phone with them. And barely 3 hours later, the thing just couldn't wake up. I've powered down and up many times now, and I've left it powering up, but still black screen till now (one day already).
Finding out about resetting PMU on the support page, I've also tried that, but it still can't work.
And you know what? I've sent this unit for repair 3 times already! First they say it's the HDD problem, so they changed that. Then when it still happened, they say it's the logic board problem, so they changed that for me. And again when it happened, they changed another logic board for me. So now, it's the fourth time, what do you think I should do? I don't think going back changing another logic board will help!
I am in fact ****** off! If Macs are great, then why me? Why my iBook? I am telling this forum that we cannot accept a big corporation giving us sub-standard products. I've since read this forum carefully and found that many of us faced the same problem! We just cannot sit down idly and let the company get away with it. This is a warning to fellow users out there that face this same problem. Let us voice out our frustrations and make Apple give us some compensation for it. I say this because I depend on my laptop iBook for presentation to clients, and this happened exactly twice when I was in front of my clients. I don't mind losing face but can Apple compensate me for my loss of business and future business from my clients?
Voice out strongly your unhappiness to Apple now!

Intel iMac not starting...please HELP!!!

Hey all,
Well I just arrived to my new dorm room in college with my one week old iMac and I'm encountering some serious problems....
I plugged the computer in while it was on my desk, with other hardware attached into a surge protector and it worked fine for about two days. Today I recieved some new furniture so I had to unplug the computer to move things around....I unplugged it and placed it flat (screen side up) on a pillow.
I plugged it back in with a new surge protector, connected the hardware and pressed the button...didn't start. The printer, the speakers, everything else had power so it wasn't a faulty power strip...just the computer wouldn't start. I then did the following:
1. Tried different connections on the same surge protector
2. Switched back to the old surge protector
3. Plugged the computer w/o external devices into the wall directly
4. Tried it as described above into a different wall outlet
And nothing has worked. I'm going to call Apple in the morning, but as you can imagine with the year starting this is the last thing I need. I'm using my old G3 iBook at the moment to get by, but what has happened to my brand new iMac? Thanks for your help

DIRECTLY from the iMac Help site:
The System Management Controller (SMC) is a chip on the logic board that controls all power functions for your computer. If your computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including:
* Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.
* Handling system resets from various commands.
* Controlling the fans.
Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues in which your computer is unresponsive—in these situations, restarting your computer will generally suffice. If your computer isn't responding, perform these steps one at a time, in this order, until the issue has been resolved:
1. Force Quit (Option-Command-Escape).
2. Restart (Control-Command-Power).
3. Force Shut Down (press the power button for 10 seconds).
Resetting the SMC can resolve some computer issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth. If your computer still exhibits these types of issues after you've restarted the computer, try resetting the SMC. To reset the SMC on an iMac (Early 2006), iMac (Mid 2006), or Mac mini (Early 2006):
1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2. Unplug all cables from the computer, including the power cord and any display cables.
3. Wait at least 15 seconds.
4. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5. Press the power button on the back to start up your computer.
The iMac (Early 2006) and later models do not have a button on the main logic board for resetting the SMC, which eliminates the need to remove the computer's cover to reset it (as required for some earlier models).
