PowerPC :: IBook Locked Up And Not Booting After Restart
Aug 9, 2007
I have an iBook G4 (1.25g memory and 1ghz processor) running Tiger. I have never had any problems with my iBook in the past and now it seems the second my warranty expires I do. I was using it earlier today and the entire thing just locked up for the first time ever and little lines started appearing on the screen. I turned it off and rebooted it and it froze on the Grey screen, I repeated and it keeps doing the same things. It actually loaded a few times and then promptly froze. I tried booting from the CD and it freezes right on the screen to select your language (if it gets that far).
I went into applejack/single user (which runs fine) and repaired disk/repaired permissions/cleaned up system files/ and cleaned up virtual memory. I also used the fsck -y check disk which I'm assuming is the same as typing in 'applejack' and then selecting 1 (But I thought I would use it anyway). The first time I ran fsck it said it changed a system file. I then ran it again and it said that the HD seemed okay. Assuming that fixed the problem I restarted my computer and it froze...again. Or is there a way to reformat from single user?

I started up my iBook today and it took me all the way through sign-in to my desktop before giving me a grey overlay with a little box saying that I need to restart. So I did and then it took me to my desktop again before scrolling code across the screen in a very messy, un-mac-like way. I tried getting into safe boot (restarting and pressing shift from after the tone until the apple and wheel show up) and it just ran the apple and wheel grey start-up screen for a while before kicking back into a normal restart and giving me the earlier results. So I went and got myself into single-user mode and ran the fsck -yf command. It told me this: Checking Catalog file Invalid extent entry (4, 190) Volume check failed Is there any way to fix this, to save my computer? I don't know anything about code or computers. My general mode of operation has been "I bought a /mac/. I shouldn't ever have to look at code."

My PowerBook G4 15" alu 1.25 ghz locked up out of nowhere the other night (while only running firefox). Couldn't even force quit, so after a long wait I manually shut it down. Then I couldn't get it going again. I pulled the battery, let it sit overnight, and then it started up, only to freeze up again in 30 minutes. Same routine yesterday (though it lasted an hour or so).
I live in Germany and the only Apple store is hours away. And of course my Apple Care is expired. I've zapped the PRAM, reset the PMU, ran first aid on disk utilities (everything came back OK), but I'm freaking out. This thing is seriously important to me, and I can't afford to replace it. I've read plenty of speculation that it could be the logic board, or that it's locking up from overheating, or maybe the hard drive is going bad (though the tests come back OK).

Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was:
1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up.
2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does).
3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...)
4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart.
5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.

I recently came into possession of an iBook G3 (Clamshell) model M6411. Unfortunately, I believe it had a cactus HDD - it shows up in Target Disk Mode on my current model 13" MBP but refuses to format or read - locks Disk Utility/Finder up when accessed. The iBook also has NO CDROM drive in it, either (removed by previous owner, reasons unsure). I'd just like to get it to boot to see that everything else works ok. I have a retail install of OS 9.2.1 as well as an iMac G3 OS X 10.1 install CD, and a 10.3 retail disc too.
I am aware that PPC Macs cannot boot from USB CDROM drives, but they can using FireWire. So, I tried plugging it in via FireWire to my MBP, put the MBP in Target Disk Mode, put the CD in it, and held Option while booting the iBook. The iBook sees the CD on the MBP, I click on it to boot it, and it shows the Happy Mac (this is with the 10.1 CD). However, after about a minute, it shows a strange "broken folder" icon (a Mac OS 9 folder with a tear down the middle) on a grey background. It gets no further. If I use the 9.2.1 CD, it shows a Happy Mac briefly then switches to a floppy disk with a question mark. The 10.3 CD refuses to boot at all. One thing I forgot to mention is if I try and boot the iBook normally, it shows a Finder icon alternating to a ? in a blue Mac OS 9 folder.

I've had my iBook for about a year and a half now, haven't had any trouble with it until now. For some reason it won't start up. It's plugged in and the green light is on but it's just not booting up. why my iBook isn't working all of the sudden?

my ibook 800mhz g3 isn't booting up. I just turned it on one day & it showed the apple logo as usual, it went to the Starting up screen, and then it just disappears and i'm left with a blue screen, and the mouse sometimes appears for about 10 seconds and then it goes away. i've tried formatting, installing an earlier operating system, using a boot cd, booting from an external hard drive, everything.

I've been given an iBook g4 (Late 2004 Model according to apple) and... It's completely dead! No lights come up on the Battery when I press the button. I've tried restting the PMU..But nothing yet. I dont have the offical Apple plug, its a replacement one. Can that make much of a difference?

I just moved back up to Jacksonville with my friend and now his iBook G4 is not booting. It goes to the white Apple screen and spins for about twice as long as normal, and then goes to a black screen with just a type-cursor in the top left hand corner which erases any text submitted. Now, from there I went ahead and booted from the Tiger Install disk and ran permission repair and also disk repair, without any glitches. Also, we then booted again and ran a hardware diagnostic and it turned up absolutely no problems with the computer. Any ideas? Luckily, he's still under his first year of AppleCare (and he's about to purchase an extension since you can now get it in Florida legally) and he should be covered.

I'm relatively new to Macs and I wanted to try a clean install (or erase and install) on my ibook. I recently purchased a MBP and since Leopard is on the horizon, I wanted to do a "trial run" of installing an updated operating system. I know that you can just hit update instead of doing a clean install, but I've been reading that things run better when you do a fresh install. My old ibook still has Panther on it and I figured I could try to install Tiger on it from my MBP disks.
I know that this represents a violation of the license, but I thought it would be worth it to ensure that I don't make any major mistakes when I'm doing the same procedure with my brand new MBP when Leopard gets released. When I tried booting from the disk from my ibook I got a kernel panic which I interpreted as a sign that it was not a good idea so I abandoned the project. Now every time I try to start my ibook I get another kernel panic and I'm afraid I just broke my old computer.

I get a message saying "You must restart your computer." (hold down the power key, blah blah).
I've researched a little bit, and apparently its indicative of a kernel panic.
It's not booting from CD either.... what's going on?

A friend of mine brought over his 14" iBook G4, 1.33GHz, 60GB HDD and 1.25 GB RAM. The problem with it is that upon start-up, the grey screen with the apple/turning gear comes up, then after a few moments a blue screen will appear, though no box showing the start-up process. I've run a few basic diagnostics on this, including the lovely disk utility (which did nothing), I've run fsck, zapped the PRAM, etc, no success as of yet. At one point, I received a screen with alternating folders, one showing the smiley mac face, the other folder with a flashing "?". I cannot replicate this for the life of me. I have attempted to acquire files via TDM, though am not able to see the hard drive despite using 2 different laptops. Possibly the firewire cable itself is spent, though it's brand new! Here is where I become increasingly frustrated: I ask my friend for the boot disks as the ones for my own 12" iBook don't work (for whatever reason). He tells me that he loaded Leopard this summer (currently running 10.5.2, no updates loaded since), then proceeds to bring over boot discs for a MacBook...:headdesk: To begin with, it seemed like the HDD was fried, however, after running disk utility (and not hearing any negative sounds), it does appear that the HDD is fine. I'm thinking a kernel panic, though not sure how to resolve these.

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

I just bought a iMac M5521 from a friend and it won't boot. It looks like it's about to start up and then it goes to a gray screen and tells me to press the reset button or hold the power button, and it says that in like 3 diff. languages. What do I do? I'm a PC guy and know nothing about Macs.

my dual 2.3 ghz G5 power mac with 3.5 gig memory running 10.4.11 started crashing (grey screen "you must restart your computer...) and soon stopped booting. suspecting the hard drive as it had been noisy for some time I ran "repair disk" in disk utility from my mac book (connected by firewire, G5 booted as target) and it booted again but soon crashed again and after a couple more crashes it would not boot and attempts to repair failed. I installed a brand new hard drive, installed osx 10.5 and updated it to 10.5.8 and it seemed to install and boot fine but while trying to burn a .dmg dvd with toast (10.0.5) I got the grey screen anain and repeated attempts to burn a disc with the same .dmg resulted in a crash every time. it has also crashed while downloading, playing back itunes hd video, and using an "eye tv hybrid" tv tuner as a dvr. below is the most recent crash log - note that most of them have referenced cpu 0 although the most recent it's cpu 1 -THANX & PLEASE HELPInterval Since Last Panic Report: 0 sec Panics Since Last Report: Anonymous 4A58CF1E-844-409F-8BF3-65A3A3CD2E79.......

I ran a disk check on my MacBook Pro which told me to run disk repair. Since this was my boot HD, I took out my Installation DVD, put it into the running system and started the installation file then selected that I wanted to reboot and start utilities. The system then rebooted, the "chime" came, and then, silence, gray screen with apple logo, nothing is happening. What do I need to do, to get further and repair my hard disk?

I recently received a friend's iBook (G4 - not sure about other specs) and it isn't booting. The computer just hangs at the Apple logo when I try to boot from the hard drive.
So I decided the easiest way to fix it would be to simply take my retail leopard disc and install it on the machine (they don't need any data recovery). When I hold the option key the Leopard disc shows up fine, but after I select it and click the arrow to continue it just sits at the apple logo with a twirling loading icon. Anyone else had this issue? Any ideas?
Do I need to reset the system profile or something? Sorry I am an old-school mac newbie... my own machine is a MacBook and I'm much more familiar with it than this G4 iBook.

I am having a problem booting up my Ibook G3 with Tiger OS X 10.4.11. The problem started when my ac adapter blew a fuse and I let my battery die completely (but it continued working after the ac adapter fuse blew). I bought a new ac adapter and the battery has been fully charged, but since the battery died originally, I have not been able to boot up. It stays on the grey screen with the Apple and the loading wheel. I reset the PMU and the PRAM and had no luck. I've restarted several times. I am hoping that I do not need the CD that came with the computer because I bought it second-hand and don't have it.

The last two lines just continue repeating. I am thinking that there might be a corrupted file but how to go about figuring that out. There is only one user login for my computer (G3).

I have an ibook g4 early 2004, my computer had problem with the HD and i had the change ir for a new one. After I installed the new hardware (samsung IDE 160 GB) my mac wont boot from the original installation CD's. It boots up, shows me the apple logo, stays there for a while and then shows me a forbidden sign. I have tried with Disk Warrior and the same thing happens. In a desperate move to see if the disk was correctly installed, i booted up a version of yellow dog linux, and it can recognize the newly installed HD. I have tried booting up the machine, pressing option button to display boot up options, but the machine freezes everytime i do that. I have also tried to run Apple Hardware test but keeps freezing also in the splash screen that shows a little mac with the words "loading...". The disk is recognized by yellow dog, so i dont think is trashed... how can i format the disk and install panther?

I have a G3 iBook and just the other day the display stopped working. There were no signs of the display going bad, it's just went. Am I able to boot the iBook via Target Disk Mode on my PowerBook and run the iBook Hardware Test CD on it? Also, can I reboot my PowerBook and choose the iBook as the startup volume?
I know how to do Target Disk Mode but the latter I'm not sure about.

My brother's iBook G4 (800Mhz, First Rev) has completely splattered itself and we're getting a new Macbook for him under insurance. My iBook G3 (White, 900Mhz G3..the last G3 Rev of the iBook) has a failing hard drive.
Now, could I swap out those two drives, at least to recover stuff? And is there a specific method of opening up the iBook G4 so that I don't break stuff (I've already messed with my G3..and ended up with a dozen extra screws ^_^
Mainly the aim is to salvage the hard drive and swap them out; replacing my faulty iBook G3 one with the iBook G4 one which is perfectly fine.

Thought the house power had gone off because when I returned home, my Mac was off. Rebooted checked email, and went to get breakfast. Came back fan running very fast, and machine is locked and no video. Turned off by holding in power button. Same thing happens when I left again. I have now been on the machine for over an hour and no problems. What is causing this?

When I select Restart or Shut Down from the Apple menu, all of my apps close, but then it just sits there showing the desktop pattern. The cursor remains live. Nothing else happens. I have to hit ctrl-opt-power to force a power down.
This happens regardless of which account I'm logged into. (I have an extra "safety" account that I never use for anything. It has admin privileges.)
It also happens if I click Restart or Shut Down in the Login screen.
It also happens if I force reboot into Safe Mode and then try to Restart or Shut Down.
This iBook (see sig below) has a brand new HD in it, and I just spent an entire day doing a fresh reinstall of Tiger and all of my apps.

Right now I have a G3 iBook (900 MHz, 640 MB RAM, Combodrive, 40 GB HDD). I'm looking at a G4 iBook (1.2 GHz, 768 MB RAM, Superdrive, 60 GB HDD).
How much faster would the G4 be over my G3. I figure that after selling my G3, the G4 would only be another $200ish on top of it. Would this be worth it?

I have the tiger family pack, so I have a license for it. It only has a CD-ROM drive, so I am wondering if I can buy a 40 GB HD, and clone the one from my G4 onto it.
