IBook freeze

I have a problem with my ibook freezing that started a few days ago; it began by freezing at the blue screen (prior to the login window), and now will variously freeze at black screen, grey screen, apple logo, or on rare occasion make it to the desktop.
The particulars:
ibook G4 800 with 512 additional RAM, Airport, 60 G HD (new)
I have done fsck (no reported issues), Disk repair utility- repair permissions, repair disk, Hardware test (no reported issues, but I couldn't do the loop test due to freezing) Disk Warrior, I installed a new hard drive with a clean install of OSX (I installed 10.3), (no effect), and have tried starup with and without the removeable RAM and Airport installed (no difference).
I'm out of ideas, but am beginning to think that the problem may be with the fixed RAM; however I can't run the ibook long enough to get a good test without freeze up. One additional note: the problem seems to get progresively worse the longer the ibook has been on, i.e. it gets further into startup say, if it has rested overnight.
Anyone have thoughts on this? Also, if it is the fixed RAM, does that mean a new logic board?
Thanks all!

I hate to add on to everyone else but the same thing has happened to me. It stalls on the opening grey screen with the swirling circle, then after about 15 mins or so it goes to an empty blue screen with mouse capabilities(meaning I see the mouse arrow, and can be moved). Im kind of runnin the same specs as the first poster. I really don't want to get have my wallet raped over getting this laptop fixed. Is there any help for us?
Cheers

Transferring Images to SD Card - iBook Freezes

I'm trying to move photos from iPhoto 5 to a Kodak 512MB SD Card via a USB card reader. Trying to move about 320 images (approx 480MB). The iBook freezes every time I try to copy the files across.
iBook is a G4 with 1GB RAM. I've tried to load them a few (approx 50) at a time, but I still end up with the iBook freezing.
I'm doing this to load the SD card for a digi photo frame for Xmas pressie. Any thoughts/ suggestions?
Thanks for any help you can give me.

Thanks - I tried that (of sorts). I dragged them into a folder from iPhoto and then tried to transfer them onto the card - didn't work unfortunately.
I did solve the issue. Much to my chagrin I burned the photos to CD then dragged and dropped them onto the SD card on my mother-in-laws windoze machine (to much gloating from her!).

IBook freezes when items are sent to print

hi there.
our iBook freezes whenever we send something to print. the icon for the printer never shows up in the icon bar and there is no reaction from the printer, but when the computer is restarted, the printer spits out whatever was being printed.
this happens no matter how many applications are open, and even when the printer's usb cable is plugged directly into the computer (our normal set-up has the printer's usb plugged into a usb hub that houses a couple other peripherals.)
any ideas?

Are you trying to download items simultaneously? If so, you may be taxing the RAM on the iPad. You mention apps download fine as long as you are not trying to download any other content at the same time. I would suggest one download at a time if the iPad is freezing when you perform simlutaneous downloads.
If you insist on continuing that way - and it is your choice to do so - you may want to close any open apps and restart the iPad on occasion if you want to download this way.

IBOOK freezes! Please help!

I was talking to my friend one day and I was saying sorry..my apple froze. He told me he was suprised because apples don't freeze.
I have been having this occasional problem for a while now. I had my ibook for about 2 years now..perfect condition..but sometimes when I am just typing an essay or makign a movie..or whatever the whole thing freezes and I have to force shut it down.
Does anyone know why this might be happenign? I have enough hardrive space..everything seems to be perfect. I update and everything..so what is going on?

Do you get a message on your screen asking you to restart your computer or does it just stop responding?
If you have had any additional memory installed I would try removing that and see if it happens again. Another thing to try would be to boot from your install disc and run Disk Utility to check and hopefully repair any errors.
Had the same problem and it turned out to be the additional memory I installed.

Ibook freeze from sleep

In trying to wake from sleep on my ibook, my screen freezes. I can move the pointer but it won't click on anything on the desktop, the menu or the dock. I tried re-closing the lid for a minute -- sometimes it helps, sometimes not. If not, the screen goes dark, and I have to re-start. Sometimes it fully restarts, sometimes it hangs before the restart is complete.
After the last freeze, my console showed about 50 copies of the following line:
ibook kernel[0]: IOHIDSystem: postEvent LLEventQueue overflow.
(The graphics card was replaced under the recall a couple of months ago.)
Anyone have any suggestions on how to deal with it?

That didn't work, but I tried re-setting the Power Management Unit, and it seems somewhat better so far.
It still sometimes doesn't find the Airport (the icon in the menu bar is grayed out) on waking from sleep, but I think I can fix that by putting it to sleep again, closing the lid, waiting 30 seconds, then opening the lid again.
Thanks for your help.

Help my ibook freezes when I connect usb devices

Hi there
I have had problems for weeks when I attached usb devices to my ibook. I have a usb (MAC approved) headset which caused the ibook to freeze when I connect it before or after startup. I also have a usb modem for a broadband connection which causes the ibook to freeze. The printer is usb also, but it only causes the ibook to freeze some of the time ????? I have run the hardware test disc, there were no errors. If anyone has any ideas I would really appreiate hearing them.
Cheers

Ibooke freezes when minimizing or using expose to show all windows

I have a bought a refurbished ibook from the mac refurb site 2 weeks ago, no other hardware, and have only installed office 2004.
It freezes often when several windows are open and i use expose to show all windows (approx 1 time in 2), and also when i minimise a window if a few apps are open. (approx 1 time in 3 or 4)
When frozen it just hangs & shows rotating disk & only way out is to restart using power button.
I Have tried hardware tests & disk utility etc...
Any other suggestions? or anyone else having a similar problem?
Would prefer to resolve myself as opposed to sending back on guarantee as I need it daily..
THANKS

furthermore..
i have spent so much time trying to sort this out over the past week that my girlfriend has given me an ultamatum;
either the computer goes... or she goes...
has anyone else discovered that buying an ibook has had such a dramatic effect on thier relationship? and has anyone got any suggestions how to resolve this?
i think the computer has to go back to apple... unless someone comes up with a fast fix.......

Is the new Firefox update the cause for my iBook freezing up?

I have an iBook (the last model before they were discontinued) running OSX 10.4 and have noticed that it has been freezing up, forcing me to do a hard reset, ever since I downloaded the latest Firefox update.
Sometimes it seems like the screen will go to sleep and won't wake up, also forcing a hard reset.
I have done some preliminary googling but I don't think I am using the right terms to get meaningful answers.
Is this a known issue? If so, can I uninstall the update? Or is it something else that I can fix? I have Applecare, but it might have expired by now.
Haven't noticed the problem in Safari, although it's only been since last night that I switched browsers and I may just not have used it long enough for the issues to surface.

Hi Liz!
The Firefox update, and your issue, coming about in close proximity, may just be a coincidence.
Exactly which model iBook G4 is it?
What is the Processor speed?
What size is the Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?
What peripherals do you have connected? A keyboard, mouse, printer, external drive or modem, router, etc?
Have you made any additional changes, like upgrading the system, updated or installed any other applications or programs, etc?
Have there been any unusual occurences, like freezes, crashes, power outages, etc?
Insufficient available space, can cause performance issues, system corruption, and possible loss of data.
Depending on Mac system usage habits, it is a general recommendation, to keep 10% to as much as 20%, of the Total capacity, available at all times.
Review the suggestions, in the documents that I have linked to below.

Have you ever run any routine Maintenance procedures, as suggested in the articles linked to below?
Mac OS X 10.3/10.4: System Maintenance, authored by Gulliver
Maintaining Mac OS X, authored by Dr Smoke
Is the iBook shutdown overnight, or does it run 24/7?
If you turn the Mac off nightly, the Background Maintenance Tasks, may not run on a timely basis.
These can also be run, using a Third-Party utility, or manually using Terminal, to run the CRON Commands.
I use MacJanitor, when necessary.
INSTRUCTIONS TO RUN CRON MANUAL COMMANDS
Quit all applications/programs.
Navigate to HD > Applications > Utilities.
Double click on Terminal, to open.
At the prompt, type:
sudo periodic daily
Press Return.
Enter your Admin password when prompted, then press Return.
This will execute the daily script that is sheduled to run every night.
When completed, repeat this procedure, but change the command to:
sudo periodic weekly
This one rebuilds a database or two, and usually takes somewhat longer to complete. It is scheduled to run once a week.
Repeat again, with command:
sudo periodic monthly
Or they can all be run in one pass, which is preferable, with this command:
sudo periodic daily weekly monthly
When the tasks complete, and return to the prompt, you may quit Terminal.
Restart the Mac, and run Repair Permissions.
TO REPAIR PERMISSIONS ON THE STARTUP DISK
1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
2.Click First Aid.
3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)

Ibook freeze, flashing file folder

My brother sold me his hardly used iBook g4 in December. The day I received it (parents flew it out to me, carried it on the plane), it froze within 30 min or so of it being on. When I tried to restart it, I got the grayish screen with the file folder icon and flashing question mark.
For several weeks, it did pretty much the same thing: would work for 20-80 min, then freeze, and would give me the gray screen upon restart. After sitting overnight, it would start up just fine and repeat the cycle. After a couple weeks of doing such, it stopped doing anything but giving me the gray screen upon turning it on.
From everything I've read, it seems like I probably need a new hard drive for it. The good news is, I have absolutely nothing on the harddrive, since I never got to use it much, so I won't lose anything. Am I better off taking it to an Apple service provider (which will be a difficult 2+ hour drive) or can I purchase a harddrive and have my IT people install it?

Welcome to Apple Discussions!
Do you have the software discs to reinstall the operating system and any applications you require?

IBook Freeze Up Memory(?) Problem

I have a 14” 800 MHz G3. It has 128 MB permananent RAM and came with another 128MB in the additional slot. Shortly after buying the iBook in 2003, I bought a 512MB memory module to bring the total RAM up to the maximum of 640MB.
Everything went quite swell for a number of years. Then, earlier this summer, our computer started doing some quirky freezing up which got progressively worse until we could not turn it on for more than a minute or so before everything would freeze and we would get the gray screen of death.
I ran the Hardware Test disc that came with the machine and it identified the problem as coming from the auxilliary memory slot. Lo and behold, when I took out the additional memory module, the computer functioned normally again (although, of course, very slowly with only 128MB total RAM). So I thought I had identified the memory module as the culprit, which seemed to be confirmed by the fact that the iBook also operated correctly (and marginally faster) when I reinstalled the additional 128MB module that had come with the machine.
I returned the purchased module to the retailer (lifetime warranty) for a warranty replacement and they sent me a new module. When I installed that one, the computer acted funky for a few times, then began to work normally. But this only lasted a couple of days and soon it was freezing up in a matter of minutes again. And again, the Hardware Test indicated the 512MB module as causing an error and removing it and putting in the original 128MB cured the problem.
I contacted the retailer and they informed me (1) that the module they sent me had been tested before shipping; (2) that they tested the module I had returned to them and found no problems with it; and (3) that the iBook memory slot is known to go bad and cause problems. Also, when I was searching for information on the web, I came across some references to the upgrade to version 10.3.9 creating issues.
Does anyone have any ideas about this?
Thanks.

You hadn't mentioned the multi-language message. What you are seeing are _kernel panics_, and bad memory is one of the most common causes.
Have you tried running the Apple Hardware Test CD with the 128 MB module installed? That would be a sure check on whether it is the memory module or the slot.
I think your RAM vendor is not being truthful with you. If the slot checks out, call and tell them that the 128 MB RAM module you have works perfectly fine in your computer, but their 512 MB module does not. This contradicts their contention that the fault lies with the computer. It can't possibly be so.
I wouldn't accuse them of lying. I would suggest that perhaps this module was damaged in shipping (and ignore their assertion that the one shipped back tested out okay). Tell them you want a replacement until you get one that works or you want your money back so you can buy one elsewhere.
Good luck.

IBook freezes - any ideas?

Hello,
I have some trouble with my iBook (G4, 14``inch, 1.33Ghz). I bought it in November 2004 and got additional memory (512MB) installed at the shop. It run fine until August 2004, when the ethernet port was no longer detected. As a case of guarantee the logic board was changed and everything seemed okay, but shortly after that the iBook started to freeze or crash now and then. After two total system crashes at the end of last year I took a closer look to the problem and found, that in the system profiler most times the built-in memory (256MB) was referred as "empty". Resetting of PRAM und PMU didn't change anything. Then I extracted the additional memory and surprisingly the iBook run fine again. I tried a new memory (again 512MB), but the iBook again started to freeze after a few minutes. My guess was that the memory slot was defect. A problem, which I can clearly live with. So I run the iBook for two days (only built-in memory) and everything was okay, but yesterday I made an intensive session (several installations and then some applications at the same time over 3-4h) and after a while the iBook slowed down and eventually froze. I wasn't able to restart until today (after about 6h, but of course I didn't try the whole night). Has anyboby an idea, what's could be wrong? Is it possible, that my iBook has a heating-problem? That's another possibility that occured to me yesterday.

iBook G4 14'' 1.33GHz Mac OS X (10.3.9)

Ronda, we're talking past each other! I wasn't trying to use a cloned drive (MBP or iBook) in any of this!
What I had learned from experience (and from advice here and on the net) was that if you wanted to use an external drive with both an iBook and a MacBook Pro, you needed to format the drive as an Apple Partition Map. And that is true.
Clearly wrongly, I assumed that if I did a fresh install of Tiger using an Apple Partittion Map, it could boot an iBook. Clearly, an Intel-Mac installs something in that scenario that makes the drive only bootable from an Intel-Mac. I had mistakenly thought it was the partition scheme the determined which laptop it could be booted from and used with!
For my future reference--and for any one else who might be in this situation--here's the solution.
1. Format the external hard from the iBook.
2. Then connect it to your MBP or other more recent device, and drag your home folder and needed programs over to the drive.
3. Now, you can boot the external drive using your iBook.
4. Any changes to documents, mail (e.g., Eudora), etc. will register on that external drive.
I wish I had thought of that, or been advised to do that. It would have made short work of reconstructing the MBP's home folder contents on its return--a simple drag and drop operation!

IBook freezes on Apple logo white screen, NO spinning rainbow wheel

Hello,
I bought my iBook 12" 1.33Ghz used in May. It has worked flawlessly until two nights ago when I was surfing the web via Airport. Everything started to take forever to load, the spinning rainbow wheel appeared several times, and applications took minutes to switch between. Since the iBook had been on for a few days, I thought it was time to do a reboot to fix whatever was backlogged in the system. It didn't want to respond, so I force quitted all programs. I could click on the blue logo and hit shut down or restart, but they didn't do anything towards a shut down. I finally held the power button to force a shut down. Ever since, when I power up, I get the Apple chime, a gray screen (for less than a second) and then the white screen with the gray Apple logo. There is NO spinning rainbow wheel, as others with similar sounding problems have mentioned. I've cleared the PRAM and PMU, but they didn't help anything. Holding Shift on startup does not do anything differently. It still just freezes on the Apple logo for hours. I did not get a Mac OS X startup disk with my computer. What else can I do to troubleshoot this? Please help, this is my first Mac, and up until 3 days ago, I had all but sworn off PC's, now this thing is acting up too!
Also, I'm guessing which version of Mac OS X I have, is there anyway to confirm without booting? Holding option is the only thing I have found to give me a different startup process, and the mouse pad is very sluggish and there's a watch logo for 20 seconds or so on it.

Hello! Since you don't have the startup disk your best shot is using fsck. Tom
when you re-start, hold down the apple key AND the "S" key You'll start up into a command line interface.. it'll look strange but just hang in there. When it's done booting up, you should see something that looks like this: localhost:/ root# at this point, type in 'fsck -f" please note the space before the dash, and of course, ignore the quote marks, then hit return You computer will no go thru some low level checks on your HD. Most likely you'll get a list of a few files that have problems and this procedure will fix them. This should take about 2 or 3 mins, so don't be in a rush. When the line says "VOLUME WAS MODIFIED", this means that changes were made. At this point you should be back at the same localhost:/ root# prompt. run fsck -f again. Wait for it to finish. if you continue to get the "Volume was modified" message, continue to run fsck -f until you'll get a prompt that says The Volume(your HD) appears to be ok, again with the localhost:/ root# prompt. AT this point, type reboot, hit enter and your computer will start up normally. This is not difficult, but you may want to give it a shot when your feel you have a few moments where you can attempt something new and not stress too much.

IBook freezes

I tried to find a post of a similar problem, but I didn't find anything that was just right.
I have an iBook G4 that freezes up about 5-10 minutes after the desktop loads (cursor won't move). I tried to reinstall the OS but 15% of the way into the installation it froze up again.
Anyone have any suggestions of what possibly may be the problem? Or something I can try to do on my own before taking it down to the genius bar? I have a huge research class this semester (am half way through physical therapy school with NO money to buy a new lap top) and I really would like to get the old bird fixed.
Thanks!

Welcome to Apple Discussions!
I think at one point that Apple did have a program for iBook G3 logic boards, but I imagine that it has expired by now.
Unfortunately, if you are past the warranty period, you are likely not covered. The only exception would be if this was a recurrence of a problem that first occurred under warranty that was not fixed by whatever repair was done at the time.
I am a little puzzled by what happened at the Brent Cross Apple Store. I do not understand why you had to go home without someone taking a look at your iBook. If you made an appointment at the genius bar, you should have had someone spend some time with you.
I don't really know of a good way to talk to Apple about your problem. Here is a link with how to contact them:
http://www.apple.com/contact/
Freezing can actually have several causes, both hardware and software. If you want more help determining exactly what is wrong with your iBook, I would suggest you post a new topic, as your problem won't get the attention it deserves buried in someone else's thread.
Good luck!

Ibook freeze at startup

My ibook is freezing at startup.
When i power on, apple logo and loading symbol comes up. It looks like it is starting up as normal but then freezes without bringing up the login screen. A code in the top left hand corner appears: sh-2.05att
Can you please help!
Thanks

I had the same problem, but no error message! My hard drive failed!

IPad 2 iBook freeze problems

Hi. I just received my iPad 2. I downloaded my iBook app on my iPad and my girlfriends and we are both having problems with it freezing when we are in the library store looking for new books. I have to turn my whole iPad off to fix the problem. Any ideas on how to fix this? Also if I delete my app and reinstall will I still have all the books that I have purchased already or will I lose them?

Hi,
If you are both using the same Wi Fi connection, tap Settings / General / Reset / Reset Network Settings.
Restart the iPads, try the iBooks store.
You can try deleting the iBook app to see if that helps. Your iBook content is stored in iTunes so even if you delete the app, your books will not be deleted.
You can see your Books/PDF's etc in the iTunes window on the left under Library / Books.
If you haven't done so, create back up your iPad(s) follow the instructions at this link.
