IBook G3 Won't Start Up It Just Goes To A Grey Screen

I tried to turn on my ibook this morning but it wouldn't boot up! I turn it on, it made the start up noise, and then it went to a grey screen with an apple in the middle of the page along with the little status gear just below the apple. When I power it on, the harddrive sounds like its trying to boot up, but if I leave it alone for a while the noise of the harddrive starting to book up stops, and the ibook just sits there with the grey screen with the apple and the little status gear thingy.
I don't understand what happened, because I was using it last night and it was working fine....
What do I do now, anyone have any suggestions, any help would be great
thanx

Hi Tigger_Rules!
See if anything HERE helps.
Specifically blank, grey screen.
If you need help with any of the instructions, please repost.
Good Luck!

After powering on, iBook G4 won't start up and fan goes crazy

I closed the lid of my iBook almost all of the way, but for some reason the display turned off. I'm not sure if it went to sleep or not; I can't remember if the front light flashed or not. I pressed the power button, but it wouldn't turn back on. I think I then held down the power button and it powered on, but the fan just started going at full speed and the computer never booted up. Since then, it refuses to boot; the fan just spins at full speed and the screen stays blank. I've tried resetting the PRAM and and PMU but it wouldn't work. Usually, the fan immediately starts going, but after resetting the PMU it takes a few seconds before the fan turns on. When I first press the power button, I can feel the hard drive "click" on. Once the CD drive did made those weird noises it's supposed to make, but the rest of the time it never does even that. It also never chimes. I'd really appreciate any help or suggestions. Thanks!

Welcome to Apple Discussions
The display is designed to automatically go into sleep mode when you shut the lid. That part is normal.
However, this part is not: it sounds like the wire connected to backlight on the lid is shorting out, preventing your machine from starting. The wire runs near the lid's hinge. Seems opening/closing the lid over time can cause the wire surface to degrade. Once the wire itself is exposed, the machine won't turn on if there is an electrical short.
If this is what has happened to your machine (sure seems like it from your description) you'll have to return the machine for repair.

TS1367 My iMac starts up and just goes to a white screen wats going on how do I fix it

When I turn on my iMac I just get a white screen how can I fix it

Hey Khagenson78,
I know you said it was white, but I found an article that sounds like it might apply to your situation. It goes over what to do if a gray screen appears during start up:

HT1349 My Apple MacBook Pro won't start up. It is stuck on grey screen and I reset all of the stuff. It still won't work also half the screen goes dark then you have to shake it till it goes back on. Please help.

MacBook Pro Older version with grey keyboard

You might have better luck posting on the Mabook Pro discussion forum, as this is the OS X Xserve server forum.
Have you tried booting it from a DVD? If so and you find the same result, then its probably a hardware issue.

My 13" macbook pro isnt starting up. I goes to a grey screen and flickers between the mouse icon and then the spinning start up icon. any ideas?

I have just updated my macbook pro 13" with requested updates and asked me to restart. Upon restarting it went to the grey startup screen where it just sticks flashing betwwen shades of grey. One shade which the mouse pointer and another shade with the start up wheel?
Any suggestions would be a great help.

You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

Will it boot in Safe Mode? See What is Safe Boot, Safe Mode? (Mac OS X)

Try a safe boot.

This boot takes longer than a normal boot, be patient. If it boots login, and see if it seems normal. If so, logout and reboot normal.

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.

Here is an example of a USB cady

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

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!!!

IBook G4 won't start up, can't find HD

My iBook won't start up. It gets to the grey apple screen and nothing else happens. Sometimes when I try to start up I briefly get the icon with the question mark inside a folder.
I tried reseting the PMU and nothing happened. I instaled the MacOS 10.4 installer CD starting up from the CD, tried disk utility but says it cannot repair disk. As a last resort I figured trying to reinstal OS X but in does not find the hard drive.
I'm kind of desperate. Would love to save some files but I'm also open to any suggestions.
Thanks in advanced.

HI Tanya,
Go here for help with the flashing question mark: http://support.apple.com/kb/TS1440
The flashing question mark indicates that when you boot the iBook it can't find the drive to boot from... Shut down your Mac. While holding down the C key, press the power button, and insert your restore disk all at the same time. Keep holding the C key until you see the Apple logo on the screen. An Installer window will open, select English. From the Menu Bar, select Utilities/Startup Disk. When that window opens, select MacintoshHD 10.x.x and click Restart. It can take a minute or two for your Mac to find the startup volume, have patience.
The reason it can't repair the disk is because it couldn't find the start up volume to repair. If you can get it to boot into the hard disk, you can then run Disk Utility from the restore disk and check for any errors and repair them.

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?
