PowerPC :: IBook G4 Won't Boot Beyond Blue Screen?
Dec 13, 2007
After installing an app ('Detour') I was asked to (or it was suggested that I should) restart my computer. I did so, and now my 1.33GHz iBook G4 turns on - but it will not go any further than a blank blue screen (after the initial grey screen that appears.) Thankfully, all my data is on an external drive. I keep my music and footage which I have shot on there amongst other things. I also have a backup on my external via Time Machine of all my data which I keep on the iBook drive, so nothing should be lost.

I am trying to reformat an iBook for a friend. Everything was running, but, there was no chime on boot. I logged into the machine, and was checking files and folders when it locked up. It actyally locked up while trying to run Microsoft Word. It now boots to a grey screen the the little "spinning" thing, and then, instead of going to the login screen, it just turns blue. It will NOT boot into Safe Mode, it will NOT boot to the iBook Install CD, I just get the same blue screen using both methods. I used Command-Option-P-R without success. I booted to Open Firmware and typed reset-nvram without success. I don't know what else to try. I am copying her files right now by booting into Target Disk mode, but, once I get that done, I still won't be able to boot the install disc to get the system wiped and reinstalled. What else can I do to correct this?

just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.

The LCD display on my ibook will get a intermittent blue tint. I have no idea what could be causing it. The LCD seems to be in good shape.

I just started my iBook g4 up and after the initial grey screen with the spinning thing and apple logo, it just stays at the blue screen straight after that. I have left it for ages and it is still there and I have tried several times now. Does anyone know what the problem is and how I could fix it?

My ibookG4 won't boot past the blue screen. I have run fsck several times in single user because it won't boot in safe mode. Every time it comes back **** FILE SYSTEM WAS MODIFIED **** and never that the volume is ok. This blue screen problem occurred after trying to hook up a wireless router and changing settings in airport. If anyone knows how I can fix this.

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 was on the internet with my iBook G4 the system froze for over 10 minutes so i did a hard shutdown of the system (held the power button) When I attempted to turn the computer back on, the start up chime played then showed the grey apple screen, attempted to start up then went to a blue screen and now stays that way. I have attempted to change the PRAM and PMU to no avail, I also restarted in safe mode but all i got there was a different blue screen with no desktop icons.

I have an iBook G4 1.07 GHz 30 gb 256 RAM with Panther. It was working fine until my HD got close to being full. Now I can't get it to boot past the Apple screen. It will either freeze there, or move on to the blue screen and freeze before the progress bar enters. I want to re-install Panther but I can't get any CD to boot during startup by holding "C", including the Panther OS CD, the Hardware Test CD, or the Tech Tool CD. I am able to boot to single user mode, where I type fsck -fy, and I recieve no errors with the hardware. I had this issue beore and my HD had to be replaced by Apple.

I have seen this talked about a fair bit, but i thought i'd start my own thread because it seems slightly different.
To start, when the computer was last running, the (what sounded like fan) started making a terrible noise, then stopped, and the computer turned off.
After that, when booting, it just goes to a grey/blue screen and sits there.
I have an iBook G4, 1064mhz, 256/30.
I dont know what model that makes it, but from the Mac website, I have tried to reset the PRAM to no avail. All of the methods listed do not seem to do anything on my ibook.
I tried using this link to reset the [URL]
I dont know which one is for my model, but i see no reset button under the keyboard, or on the case. There is a little tiny hole on the case beside the LCD???
I have tried the shift-ctrl-opt-power but it doesnt do anything.
As well, i did hold down the "option" button when booting, and it brings me to a screen which shows an image of a hard drive with a green "x"
I dont know if the green means good or the X means bad..
I have read that resetting PRAM and/or changing the resolution seem to help the problem, but I do not know how to do either.

I'm trying to resurrect an iBook (translucent white case, 14.1 LCD) that was long neglected, so not sure on its past service history. The following do NOT work: - won't boot up past the gray screen with Apple logo and spinning gear icon (just hangs) - same problem if I try to boot from install DVD ("c" or using "option" then selecting DVD) - same problem with safe boot with "shift" - reset PRAM It will connect via firewire target disk mode to another computer, and I used that to completely wipe the disk and do a clean install of 10.5. When I tried booting into single-user mode (cmd-s), it fills about 2/3 of the screen with normal-looking messages, but then hangs after this (no keyboard response): Got boot device = IOService... [various other stuff] BSD root: disk0s6, major 14, minor 5 I'm out of ideas. Any suggestions? The machine is old enough that it's probably not worth the diagnostic fee of the local Apple shop. Since I can't get it to boot, I can't even run TechTools.

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.

I've been reading the other post and searching for ways to fix this. My ibook froze a couple of days ago, so I pressed the power button to do a hard turn off and then restarted it. It hasn't made through the blue screen since. It seems to load all way and then stops at the end, but stays on the blue screen. The mouse is not frozen though, I noticed that was a problem for some people. So I've already tried a lot of the suggestions I could find. I've tried resetting the PMU,Start your computer holding the ⌘ and S key on your keyboard. When the black screen turns up and the "writing" stops, you will see something like

I have an ibook g4. It freezes at the blue screen with the apply on it. The little circle goes around and around but nothing happens. I took it to an apple technician yesterday who told me the hard drive is toast so I should just throw it away. (Actually, he offered to take the keyboard.) When you do the fsck -fy it says that the hard drive was repaired sucessfully. Is it possible to have a hard drive that is bad and a message which says it has been repaired successfully? I don't mind having the hard drive replaced if that is what is wrong. I do not have any of the install discs any longer.

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.

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

My macbook pro cannot boot pass the blue screen, all startup keys failed to work [URL]. If all I need is one successful boot to copy all my files off the hard disk. Should I:
A. leave it as it is and hope for the blue screen will eventually go away;
B. keep rebooting and hope for the computer will boot up correctly by chance; or
C. Power off and unplug everything, leave it overnight and try booting it again next morning?
I've heard some people could get their computer back to normal just by option C, which sounds weird to me. Is that possible? How does that work?

I hardly ever turn off my Macbook unless i need to - I just close it and use it whenever i need to. I let the battery run dry as Apple suggests to do every now and again, and turned it on the next day. It started to boot and took a little longer to get past the grey apple logo and loading circle and then froze on the blue screen. I can control the mouse, but every few seconds it changes to a darker blue, cursor disappears but returns after a second or two. I've tried:
- Booting into safe mode (Same thing happens)
- Booting from CD and repairing permissions (Said everything was ok, same thing happens when I booted)
- Single user mode (used some commands from an Apple page and restarted)
I can however boot into windows perfectly fine, which leads me to suspect it's a corrupt log in item. I'd like to know for sure it's not a hardware problem so I don't have to take it into an Apple Store.

I have a fifteen inch 800 MHZ 768 MB ram iMac G4 and for some reason it won't boot up. The apple screen shows up, goes away and then the screen is apple-blue with the cursor you can move around. I left it on overnight and it didn't get past the apple-blue screen. What do I do?

Mbp had a kernel error and would not boot so I took it to Apple store and they said it needed new harddrive. I installed a new hard drive and 8gb of ram while i was at it.When trying to install the OS on the new hd, it would stall at random points every time, so I made another appointment at the Apple store.The morning of my appointment I managed to get the OS to install but then it froze in the setup stage so I went ahead and went to my appointment.This time they suggested it was the hd cable, so I got that replaced and the mbp was working fine when the guy brought it back out to me.When i got home i tried to install Snow Leapord, it froze, and now I cant do anything.Now when it boots I get the apple logo screen with a loading circle underneath for about 1 minute, and then it goes to alternating between blue screens, one with a loading circle and one without.I've tried all the basic bs stuff and nothing has changed?

MacBook Pro, Mac OS X (10.6.8)

Display flatters for up to one second while doing the regular boot.Means it gets blue with Apple logo bright - like a negative of original screen.Was not observed with Mavericks first releases .1, .2.iMac Late 2013, 27 inch, NVIDIA GeForce GT 755M 1024 MB.Again possibly a problem with SMC and it's reset as first solution candidate,or rather graphics?

I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.

Today, when I have been playing Warcraft III, randomly everything will freeze and I will get a blue screen of death error for a fraction of a second, then my laptop will restart.
I am currently playing on a Macbook Pro with bootcamp for windows XP with service pack 2.
