PowerPC :: IBook G4 Blue Screen Assistance - Change The PRAM And PMU?
Dec 20, 2009
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.

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.

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 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?

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.

My wife accidentaly dropped our ibook with the screen open. It landed on the corner of the screen, and the right hinge cracked a bit.It still close, but not perfect. It also seems that the hinge get worse every time I open and close it, so I left it open.happened a couople of weeks ago, and the machine it self runs perfect (or so it seems, no trouble since)I took it to my local Apple center and they said the hinge is a part of the screen, so to fix it they?ll have to change the screen. This is very expensive, especially due to the fact that it still works perfectly.The guy added that they MIGHT be able to improvise and just glue (or whatever) the hinge What do youthink are the chances that they can fix it without changing the screen?

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 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?

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 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.

About eight months ago I had to change the hard drive in my ibook. Because I did that change in Germany, some features are in German. Others are in spanish because I lived in Mexico. How do I change the language settings for the programs and operating system. (I hope I am explaining this correctly)?

My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

For the first time ever, my Titanium Powerbook won't load OSX. I was using Excel when the beach ball started spinning. I've had that happen, so I just went to force quit. It wouldn't force quit for me. So I let it sit a while and tried again. Again, it wouldn't force quit. So I tried to Restart the Mac. It restarted, but when it did, I don't see the OSX load screen. I get a blue screen with the spinning lines, but that's it.

When I press the power button on my eMac, it takes extra long on the gray screen with the Apple logo and the spinning gif, then takes about two minutes on the blue screen with just the spinning gif, then goes to a solid blue background, with a functional cursor, but no OSX. I've tried trying to eject the CD tray at all points in the startup process to put in the Mac OSX re-install discs, but it doesn't respond. What should I try before sending it in to an Apple store or Cupertino?

I software updated my iMac g5 (powerPC 1.6 OR 1.9GHz), with the mac OSX updated(170mb), and it never fully completed the download, said it had problems with the package. So I restarted it, and now its just stuck on the blue screen with the grey box (where it loads the IP extension, etc).
