Ibook g4 won't read RAM

I have been having a lot of issues with my ibook g4 1ghz lately. I replaced the hard drive, and in the process I am worried something may have gone wrong, because now it is only reading 128mb of built in RAM, I had a 1gb stick in there. I bought a new stick thinking maybe the old one coincidentally went bad, but upon installing the new stick it wouldn't read that either. Any help?

Are you sure it's seated properly and was handled correctly?

MBP/iBook won't read repaired USB drive?

I have an ativa thumb drive I've been using for a few months now. In the past few days suddenly my MBP (also an iBook) gives me the message "Disk you've inserted cannot be read by this computer - Initialize / Ignore / Eject."
So I opened Disk Utilities and ran 'repair disk' and it said minor repair was needed to the header. Ran repair disk it says disk is repaired. Run verify disk and it stops saying the header needs minor repair. Run repair disk, it says disk is repaired. Computer still won't read it.
I boot up from my startup disk and again open Disk Utilities from there. Run Verify Disk and Repair Disk and both say no repairs are needed? For grins I checked my HD and a minor problem was found so I ran repair disk on it. Disk Repaired. I've rechecked both drives nultiple times and each time the reslt is no repair required.
I launch from my on board system (i.e. without startup disk) and again computer says disk can't be read - initialize / ignore / erase? In fact I get 5 windows with that same message in rapid file on my screen.
Any idea what gives? If both drives are OK - why won't it read the info as before???

IBook g4 won't boot from CD or read CD but will boot from and read DVD

My iBook won't read from CD's anymore. I can put in my 10.4 Tiger DVD and it boots just fine and will mount just fine but when I insert a CD it will think for abou 10-15 seconds then eject it. I can't get it o boot with any diag tools on CD either. Any tricks

I've been having a similar problem. Can't boot from diagnostic disks (Disk Warrior, Norton, and can't use certain functions of Disk Utilities on Mac OS disk). What's more, I now have 3 partitions on my hard drive and I didn't partition it! I tried wiping the HD but I still ended up with 3 partitions. Permissions keep changing on my files. I haven't been able to access the other volumes to see what's there. I feel as though something on one of the other volumes has taken over the admin privileges for my iBook.
NAV finds nothing, but also tells me I haven't permission to scan certain files in the priv, usr, bin, and similar files.
Disk Utility repairs permissions temporarily, but only on the one partition I can access. When I try to use it to look at other vols from the CD, it shuts down and restarts my computer from the HD.
What's going on and what can I do about it? Apple claims it's impervious to rootkits et. al., but I'm beginning to think one has gotten onto my system.
Has anyone else heard of similar behavior and a way to remedy?

Ibook G4 won't start - beeps 4 times-flashes 5 times

My ibook G4 won't start - beeps 4 times-flashes 5 times. It has been working great - I installed 1 gig ram and new hard drive last week and pro tools. It has run for a week great then this. Very Frustrated.

to whom ever may read this.
I took the keyboard off and made sure the ram was secure ( took it out and stuck it right back in) and everything SEEMS to be working. (maybe it got knocked loose from when they inatlled the Hard drive - which was done after the ram installation - or just got bumped) - If any one has had these problems I would still like to know how you solved them - this was very scary!!!

IMac won't read startup disk

Longstanding problem. Older iMac won't read the Leopard disk. I got around this by using my daughter's iBook in slave mode and then installing 10.5. Everything works but I can't start up with the disk to use disk utilities. It was suggested that I get a new ext dvd drive which I did. (Kanguru qs2)
I started it up and installed Office for Mac without a problem. Then I tried to use the 10.5 disk and it would not read it. I had a hard time getting the disk to eject. After it did eject I tried using some other disks including Office and none of them work now. Any ideas?

Sounds like your new drive broke.

Won't read selected CDs & CD-Rs

hey guys!
why is it that my iBook won't read/load selected CDs and CD-Rs which my PC can? how can i fix this problem? thanks.

I believe there are detailed instructions in the Nero user guide. Download it here http://www.nero.com/en/UserGuide_Burning_ROM6.html
and search it for "Mac".
Of course, if this doesn't help, please post back! But I hope it helps.

IBook G4 won't boot using Install Disk

My iBook g4 won't boot from its original Mac OS X Install Disk (10.4.2).
When I try to start by holding down the 'C' key, the drive starts to spin up the disk, but then starts up from the hard drive.
When using the System Preferences to select the install disk as the start up drive, it shows in the preference pane, I can select it, but when it restarts, I get a flashing question mark before the computer continues by booting up from the hard drive.
I've also tried holding down the 'Option' key to run the Apple Hardware Test on the disk, but my internal hard drive is my only option when trying this.
I find it odd that the drive would work normally for all other purposes (reading/writing CD and DVD's), but will not start up from it.
Thanks in advance for any thoughts or suggestions!

An update:
I tested the startup disk using an external FireWire DVD drive and received the exact same results as when attempting to boot from my iBook's internal drive.
Since it's definitely not the drive, I'd have to agree with you that my install disk is bad (although I'm still at a loss as how an undamaged install disk goes bad).
You mentioned that Apple Support would replace the disks for a fee. I went through the Apple Support page and which led me to a page informing me that I had to pay $50 to talk to them once about this issue. I'm hesitant to spend $50 on a call where they'll tell me I can purchase new 10.4 install disks for the discounted fee of $50+shipping for a total investment that's almost the cost of simply upgrading to 10.5.
Has anyone actually purchased replacement install disks from Apple? I'd be interested in knowing what you were charged.
Or is there another method of contacting Apple regarding this issue that won't cost me $50?

Ibook G4 - won't start up, spins, and shuts down... disk utility repair...

ibook G4 - won't start up, spins, and shuts down... disk utility repair quits. says "invalid sibling link" "volume check failed" "1 volume could not be repaired because of an error" "the underlying task reported failure on exit"
any ideas about how to start and/or recover data ??
thanks

Hi chesterday, and a warm welcome to the forums!
You must repair the HD, your best bet is DiskWarrior from Alsoft...
http://www.alsoft.com/DiskWarrior/
You'll need the CD though.
Unfortunately, Disk Utility can't fix all that much, and the only other Apple Options are erasing the HD, or installing OSX to a second drive, then using Migration Assistant to move stuff over to the new HD.

My ibook g4 won't start anymor from the harddisk. so I tried to reinstall the system from the orginial system cd. Doesn't work. It says the system cd is damaged. What should I do?

I would question that error message if the Mac OS X 10.5 DVD doesn't work, either.
What error message(s) did you get with the Mac OS X 10.5 DVD? Is the Mac OS X 10.5 DVD the full retail install DVD, an upgrade DVD, or a DVD that came with another Mac?

My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )
Here is a link giving further details about this chip solder problem.

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

My iBook G4 won't turn on

My iBook G4 won't turn on. I was charging my iPod. I took out the iPod charger and the computer suddenly went dead. When I pushed the power button, the fan comes on but nothing else happens. I've tried taking out the battery and plugging the computer directly into the wall without the battery in it. I also tried all the troubleshooting tricks on the Apple website, and nothing has worked. I need help!

I am having this same problem. I let my iBook g4 12 inch (purchased in Jan 05) stay sleeping on low battery a few times recently and when I was later working with it the screen would go black, and after a reboot attempt I got nothing but the fan running full blast. At the suggestion of others on the internet I pinched it on the left near the track pad and it started up. Is there a permanent fix to this or is it just a matter of time before I have to kiss my laptop goodbye? How much time do I have to get all of my information off of this machine?

My iBook g4 won't boot up

My iBook g4 won't boot up.... I tried the option key and there is a reset option maybe and then it loads and after that the blue screen comes and after that only blue.

Hi, and welcome to Apple Support Communities.
It sounds as though it could be having hard drive problems. Have you tried starting up in Safe Mode? If not, I suggest that you give it a try. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if you are able to do a little hard drive maintenance to help things out.

IBook G4 won't sleep on schedule

I twice tried resetting the PMU as per Apple's instructions (power off then press and release shift, cntrl, option and power buttons) but it hasn't helped. My iBook simply won't sleep when it's scheduled to. The screen darkens when it's supposed to but no sleep.
This is the case both on battery and when plugged in. Both with external keyboard attached and without. Both set at 3 hrs and 1 minute. And it's been happening for several days.
It will only sleep when I close the lid or select sleep from the Apple menu.
Only recent software changes were the latest Apple system updates.
Ideas? Is there something else to reset?
Thanks.

Your method seems to have worked. My clock went back to 7:01 on 12-31-1969 (after I turned off the Airport, that is; the first time I tried this it automatically give me the correct date and time, so I wasn't sure I'd done it right). Then the iBook went to sleep on its own about 30-60 seconds after the screen went dark.
I should note, though, that I didn't wait that extra 30-60 seconds after resetting the PMU the first way. So that first method may have worked, too -- I just assumed it didn't when the iBook didn't go to sleep immediately after the screen dimmed.
Anyway, thanks for the great tip. Any idea why Apple doesn't mention this on its support page on resetting the PMU? Do you know anything else about this issue? Like why the PMU get's screwy to begin with?
Thanks again.

DVD drive won't read disks at boot

I have a Paviliton DV6-2113sa running Win7 HP 64bit.
I removed Acronis True Image and when I rebooted I got a BSOD at the point when the coloured balls should merge into one.
I thought OK, put the system repair disk into the DVD drive and boot up, but the drive is failing to read any recovery dosks. I think the drive has packed up as I haven't used it for some time.
Can I use any replacement drive in this model or must I get the same one again?
The drive light flickers as though it is reading data but it doesn't 'spool up' to speed and I don't get the 'press any key to load from DVD'.
The BSODs are a seperate issue which I think running a system repair will fix but I can't as the drive won't read data.
Is it possible to put the repair disk files onto a 4gb USB stick and if so, how do I do it?
Thanks.

Hi Peeps
I had exactly the same problem with my Macbook, again from the UK. Really weird though as would intermittantly read DVD film's which worked fine previously.
Well.... Took it to my local Apple store and saw a genius and anyway they replaced the super drive and logic board (surprised about the logic board!).
But just got it back today and the DVD drive is completely fubard so is being returned tomorrow to get this sorted!
Moral of the story, sounds like a drive or board problem. Will keep you updated when I get mine back
