PowerPC :: Ibook Won't Recognize RAM / Showing Grey Screen
Oct 16, 2007
So i bought a 1gig RAM stick for my iBook for Kahlon. Kahlon said that this RAM was supported for my iBook. The specs for my iBook are 12in, 1.2 Ghz, 120gb hard drive and 1.25 gigs of RAM. Ok so I put in my RAM in about March and it worked fine for about 3 months. Then in late July my Mac started showing the "Grey Screen of Death." So i thought that it might of been the hard drive so i did some repairs and nothing changed. So then after that I reformatted my hard drive and reinstall Tiger and nothing changed either. So i finally took out my RAM and tested to see if that was the problem and low and behold my computer ran fine (a little slow because it was was running on 256mb of RAM but it ran fine for about a week). Then I put the RAM back on in it but the Computer only read that the 1gig stick was actually a 512mb RAM stick but it still worked fine for a week until I installed a update and so I had to restart my computer (restart being the Key Word). So when I restarted my computer my computer recognized that it had a total of 1.25gigs of RAM. But when i went to start up itunes or any other application it would immediately show the "Grey Screen of Death." Does anyone know what could have happened I think that it is the Logic Board but I don't know.

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.

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.

my problem: IBook G4 that recently on reboot is just sitting on the grey screen with the spinning icon as seen here:
what i have done: basically followed apple's tips here
1- booted into safe mode; no change
2- booted into safe mode with shift-command-v to watch the boot; and it just loops around and around; no change
3- reset the nvram/pram; no change
4- booted into single-user mode; ran "fsck -fy" and returned with no errors and "...OK" and rebooted; no change
5- would move on to using my boot disc, however, here is the difficulty- my cd player gave out a bit ago and never replaced it.
so any suggestions? put in a new cd drive? would it recognize it? bring it into the store? i have searched around and haven't seen what to do in my kind of case.

I have an iBook G4 (Late 2004) that I just recently upgraded to Leopard using the 10.5.6 DVD included in the Mac Box Set. Whenever it boots, after the chime the screen stays black until the login screen. This happened occasionally with Tiger, but I found a post somewhere where someone suggested to hold the power button while powering on until you hear a beep. That solved it in Tiger, but I have not once seen a grey Apple screen in Leopard.
I forgot to mention that I have reset the PRAM and PMU.

before I went to bed, I was playing the Sims 2, when my iBook G4 crashed. Our power cord can be a bit dodgy, so sometimes that happens. I didn't really think about it much, just closed the laptop and went to sleep.Last Monday morning, I opened it and pressed the power button. It began turning on, and got as far as the grey screen with the apple and the spinning circle. And then it just froze. The circle stopped turning.
I freaked out a bit, and restarted it a bunch of times, each time with the same result. (One time it stopped spinning, and then told me a restart was required. Huh. The rest of the times the exact same thing happened though.) I even tried unplugging and removing the battery, but it made no difference. So eventually I just shut it and decided to try again later.Last Tuesday I opened it and pressed the power button without much hope, and again the apple and circle came up just fine, then stopped, but then a bunch of words and numbers popped up.I'm a complete computer noob, but they don't look good to me... or are they good?

I have an ibook g4 1.2 ghz 14 inch model with the 60 gig HD runnig Os X. One day, it start freezing up, and when I restart it, it would be fine. However, after a couple of day, it would not longer boot and I would get the folder with finder and question mark. I ran the hardware test on the CD, and it said I had a mass storage error. So, I went and bought a new hd and put it in. (another hitachi one, exactly the same). So i boot it up, run the hard ware test and it is fine. Then I go about installing os x and stuff, and everything is fine. However, on my first restart a couple of hours later, my computer no longer boots up again. I run disk utility, and it does not see any Hard drives, and when i reattempt to install my os x, it can not find a destination folder. What is going on? Also, I have the old HD from my ibook that I put in my external Hd case. If this thing is not actully broken, can I use it to boot through the usb 2.0 drive on my mac? I tried to plug it in, but for some reason no power goes to it, but if i plug it to my desktop, it powers up. (the light on the case)

Part of my iBook says there is an initialization error when I open up the DVD program, and the other part of it says I have have no drive at all. But I have tried everything that I was told to do. Basically I have a problem with my white iBook Laptop, a G3-4 800 mhz, which runs on OSX-10.14.11, and has 384 sd-ram
It has a DVD application program, but opening it just gives an initialization error. The date on the App is something from earlier this year, so it's not that old. It has the corporate "DVD" player logo. (but it won't open) If I drop down the Apple menu at the top corner, "About this Mac" I see the list, and if I select Burners, it says No Burner Found. If I look for CD or Audio devices, there is nothing like that on the list but i can find the cd drive under ATA drives (it has the HD listed, and then a CD drive). When I open Disk Utility to find out about 'repairing disk permissions' all I see on the left side of the screen are 2 drives: the hard drive and a CD drive (LG Model 8245B), and I cannot select 'repair permissions' or 'verify' because they are in light grey (un-selectable). If I click on 'First Aid" bacically nothing happens. It's sort of like "nothing's broken, nothing to fix."
So I went on to reset the PRAM, as this was the last suggestion
someone gave me.
Some interesting things: The thing plays CD's. It detects a CD drive, like I said. There is no CD/Audio player Application, anywhere (i was looking to see if it was read/write). There is also, buried somewhere, an older Apple DVD application, for an Apple DVD player. It wants to run on OS-9. So I open OS-9, and after OS9 has opened, it tells me that OS-9 doesn't support it.
The DVD application I mentioned earlier (it's about 28 MB) is newer, and runs on OS-X 10.14. (So.. yes, this was an OS-9 computer which got upgraded to OS 10.4.11)
Lastly, it came from a brother in law who is a filmmaker, and I know that he used it for DVD's. I was told i could also burn with it.(it doesn't burn cd's right now) He re-set some names and passwords when he gave it to me; from what I can see, all the 'permissions' are ok, and set to my name. I have his passwords in case I need them.
If the computer has forgotten that it has a DVD drive, then I can't run OS 10 (which is a dvd), if it were to crash. This worries me, since I had to do this with my old Pismo only 2 months after buying it (at least it had a dvd drive!) I lifted the keyboard to see if there was a label on the cd-dvd player.
Nothing. I can't pull it out (like I could in my old Pismo) to examine the underside. How does it come out? (it's a tray-loader)
Before I start trying to remove the drive, just to see what it says...
Is there any program on the iBook which will actually detect, and tell me what hardware I have? I think that the computer still thinks it has the old cd drive in it, even though it was obviously upgraded to a dvd drive. If I could find out the brand I could maybe download some software driver
for it..?
(i am sort of afraid to go poking around the system files if I know that I cannot use the OS- 10 startup disk when it crashes (since it is a dvd)...
So is it beginning to sound like there WAS a dvd drive in there first, which burned out, and was replaced by a cheaper LG (that's Dell) CD-R drive

My iBook could be on it's last leg. I have an iBook G4 1.2 Ghz with 512 mb of RAM running 10.3.9. It started about 2 to 5 months ago. When I restart my computer, instead of the white screen with the grey Apple logo that appears during a normal start-up, I get the grey screen with a flashing box with a picture of the world inside the flashing box, then the small flashing folder that flashes the OSX logo, then a question mark (?), then it would go into the normal start-up screen (white w/Apple logo). I thought this was the Safe mode boot.
Well, recently, it would just stay on the flashing OSX logo and "?" and nothing would happen. So I would do a forced shut down (holding the power down) and power it back up. Same thing. I'd repeat this for 30 minutes to an hour, restarting anywhere from 15 to 30 times and it would eventually work.
So, the flashing OSX logo and "?" happened again last night, and I could not get it to boot after countless restarts. This morning, I grab my iBook Install disc to do a full restore. I restart and hold the C key to boot from the install disc. I go through the normal steps and when I get to Choose the Drive or Destination tab, my hard drive isn't listed. Nothing is listed. I reboot holding the option key to run the Apple hard ware test. Airport passes, Logic Board passes, then I get an error when the Mass Storage test runs. Reboot and run Test again, same results. I reboot to the install disc again and it still says no drive. I open Disc Utility and the only drive it reads is the iBook Install Disc. I restart normally, and it loads fine, and I instantly come here to seek a diagnostic as to what my problem is.
I don't understand is the strange frequency or my problem. Sometimes it works, sometimes I have to restart it a dozen or so times. How can it not recognize my hard drive [I]some[I] of the time and not all of the time? I don't want to do a full restore just yet. I'd like to know what my problem is before I do anything drastic. I do have my hard drive backed up.

I�m not new to macs, but i am to my ibook g4. I just got this for my birthday and it is a secondhand Mac. I cannot for the life of me figure out how to change the question mark, apostrophe, and others on the keyboard, to actually type what they are.
This is the question mark: �
this is the slash: �
it also does the same thing for the apostrophe and the quote.

I had to replace the hard drive on my daughter's iBook G4. I replaced the original Toshiba with a seagate 160gb ATA drive. When using the original install disk, the installer cannot find the hard drive to install the OS on. I was told the problem could only be the cable or a DOA drive; so I got another new hard drive and replaced the replacement, being sure that the cable was connected properly. In the past, I've replaced hard drives several times in various machines I've owned.
I seem to remember that on one occasion I had the same problem, and found the unmounted drive with Tech Tool Deluxe that I had gotten with an old AppleCare purchase. On this iBook G4, however, the Tech Tools disk won't boot the machine. Perhaps I am mis-remembering that incident, but I'm pretty sure that I was able to mount a hard disk in the past using some sort of software. Problem is that this iBookG4 won't boot off of ANY of my older system disks I own.

Ive searched all over, and cant find a solution. I put in a new HD for the 1.2ghz iBook 12", and it wont be recognized by the computer. I tried resetting the Vram/Pram, with no success. I also made sure the hd connector is connected. When I hold down "C" to the install disc, it reads the disc, but does not detect the HD. When I do not hold down c, it takes me to a question mark/folder icon.
I do not think its the new hard disk or connector or logic board, because I have read others having the problem...some say it is the firmware, and that its the OS/Installer disc that has the error...but I have no clue how to fix it.

Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.
Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)
and
the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.

It makes the startup chime, and I've tried resetting the PRAM and PMU and none of it works. Apple store said they thought it was hard drive failure, but I doubt it because it won't boot from CD either. Do you think it's logic board failure?

When I turn on my computer, the wheel keeps spinning and stops on the grey apple screen. If I leave it there for a few minutes, the fan gets really loud.
I tried pressing Apple, Option, P, R, but it only chimes once.
I also tried holding down shift and restarting.
And I tried holding down option and restarting.
I even tried to take out the memory and put it back in.
Nothing is working.
I have the startup disks, but I don't know how to put them in the cd drive.
Since the computer won't boot up, I can't open the tray.

I'm a film composer in the middle of a deadline, and my G5 crashes won't boot again, only get grey screen with Apple and spinning logo.Boot from Applecare disk, run tech tool, hardware fine, disk is corrupted. Catalog B-tree stuff. Cannot re-build without destroying data.Of course I have a clone of my system drive and try to boot from that, but IT is corrupted too of course!Go to Apple Store (I have ProCare), then run diagnostics and find the same. Advice? Wipe the drive and start from scratch.I do just that. I own about 35 plug-in instruments for Logic 8, so it took two days. The same thing happens. Disk won't boot.

Greetings and saluations everyone. I've recently delved into the OSX world via secondhand eMac. The specs are eMac (2006 - not a typo... this is what it says)/1.42gHz/80GB HDD/1GB ram/etc. It came equipped with 10.4.6, did an update to the software and it brought the machine to 10.4.11.
After a week or so of tinkering, I think I have accidentally deleted some very necessary system files. Given that the computer did not come with any manuals or recovery discs, I've been doing some major digging over the last three days via internet and can not come up with a fix for my new love. I saw this post on MacRumors and it nearly is exactly what I'm experiencing: Mac chimes upon pressing of start button, goes to greyish screen with grey Apple logo and a spinning progress indicator then the computer goes silent (no HDD/CD activity)... yet keeps the active grey screen.
I've tried booting into safe mode but to no avail which leads me to think I've accidentally deleted some extremely necessary boot files. However, I do not remember emptying the trash during the last successful boot... is there a way from a command line prompt to "put the files back" to where they go?
I've downloaded several Mac OSX Leopard torrents but can't get them to boot off of USB drive, DVD RW external drive, external USB hard drive nor via OSX 9 CD ... Indeed, I am trying to burn from windows but have learned of several utilities which create ISOs in Mac Format and will decompress DMG files (ISOBuster & TransMac).
Please... will someone give me some good news? For example, telling me there is a way to boot from USB drive (and in what format the mac needs to boot - ISO? DMG? Expanded file system in appropriate directory folders? I don't care about wiping the hard drive... that's absolutely fine... I just need a working system again.

The other day the screen started blinking randomly. It'll flicker for a few seconds and then go white with vertical grey lines for a few seconds. Then it will go back to normal. There doesn't seem to be a pattern to it. Sometimes it will go through that process for five minutes and then stop. Other times I can be working on it for hours and nothing will blink or act screwed up.

My Mum has just turned on our family computer- an iMac G5, 1.9ghz 17" (first model with built in iSight).
It gets to the grey screen with the apple, with the loading icon below it, then after about a minute the fans turn out pretty loudly, and it goes no further, just stays on the grey screen.

I changed the permissions from read only to read and write on my start up HD and chose the change everything inside option to read and write. After I did this, my secondary HD no longer allowed me to use it saying I did not have permission. When I tried to change it all selections were in custom mode and would not accept my changes. Same with my main HD.
I rebooted and the grey screen shows up with icon and no spinning wheel. I tried safe mode...same thing. I even tried booting off my back up firewire drive and got a null sign on the grey screen instead of an apple icon. Booted up from the G5 disk and tried to run utilities permissions repair and it would not do it, gave me an error, "No valid packages". Ran disk repair and it said nothing needs repairing. I then booted up using Disk Warrior and rebuilt the HD's directory successfully, but still the G5 will not boot past the icon grey screen, no spinning wheel. I'm spinning though...HELP, I'm dying here. FYI this is a G5 dual core Cypher running Leopard with 3.5 gigs of ram. The start up HD is 250 gig and the secondary is 500 gig

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!

Ever since I sold it here on MR and got it back, there has been a problem with my 12" Dual USB iBook G3 500MHz's screen (lord, that's a long name). Whenever the screen is tilted back farther than 45 degrees or so, the backlight shuts off. I can open the casing and fix it if it's possible. Does anyone know what the problem with it is? I'm trying to get it fixed up and ready to sell back to my friend as his first Mac, and I'm trying to get every problem resolved

I have an rev. A iMac G5 that was purchased in January of 2005. The applecare has long expired. However, in May of 2008 due to factory defect Apple replaced the logic board, power supply and super drive [URL]. In December 2008 after experiencing problems with my hard drive I took my computer to the apple store. There they said it was dying and it would be cheaper to replace it myself. After purchasing a seagate hdd [URL] my computer won't recognize it. It stays at the black screen while the power light glows. After a few minutes the fans kick in at full force. I tested the hdd in another iMac G5 rev. B and it works fine. Any ideas on what the problem is or how to resolve it?

I have a Powerbook G4 with me and it doesn't boot up. I am suspecting it is hard disk/ software error that is stopping it from booting up. Here is what I see when I try to power it up: White screen, Apple logo with the round circle with rainbow color. Do you guys think that is is a software error that is stopping it from booting up? The last thing I did was to install Windows Messenger for Mac! I am thinking of trying to do a re-install using the disc that comes with my Powerbook purchase but I am at a lost of what to do. Can anyone please share with me the steps that I need to take? I've got a 'new' hard disk already, please advise on how can I rebuild my Powerbook!

...as the color green becomes dominant. The background on the browser is a faded greenish color, and the desktop image is degraded. Got some dandy streaks too! Searches say maybe logic board, but the guy I bought it from said it had a new logic board installed. Cables was a thought, but rotating iBook does not effect changes. I've shut it down for the moment, but am anxious to pinpoint the problem?
