PowerPC :: G4 Ibook Dead - Blank Screen - Fan Runs On High Speed?
Nov 22, 2008
I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.

I purchased my PowerMac G5 in 2003 and no problems till now. My problem is that on startup, the display first shows gray screen with a globe in a white box flashing in the center of the screen. This continues for about 90 seconds --- then the globe in box icon changes to a small file folder icon with alternating face/question mark flashing in the file folder. At about the same time, the fan speeds up dramatically. The fan continues to run at this high speed for about 90 additional seconds, then the fan returns to normal speed, and the startup continues normally to the blue screen. Once startup is complete, computer runs okay. The whole process takes about 4 minutes.
Information:
PowerMac G5, 1.8 Ghz, OS X 10.2.8
Mac OS X (10.2.x)

I just got this iBook 12" in the mail been to a mac shop before I bought it where the owner was told the screen had died. Motherboard was said to be Ok by the repairer. I replaced the screen with a know working one and the screen was dead. Then after the fiddle of pulling it apart again wondered if I could use the hard drive on another ibook. The hard drive I put in another iBook which loaded up fine with display. Later I tried again but it was a dead screen? Is it that both ibooks have faulty motherboards? Motherboard determines a display? Or could it be the display module? What else could cause dead screen? Cables good.

I need advice choosing a wireless router. It will be permanently connected to a pc but I plan on using its wireless for my IBook G4. My wireless card is 54-Mbps AirPort Extreme WiFi 802.11g. I am looking for whatever will give me the highest speed, reliability, and least amount of interference (I live in an apartment complex with multiple networks).

I signed up here to ask a life or death question for my iBook G3 While transferring through an airport last week on one of those moveable walkways, I got clipped off by another passenger who was running through the terminal to catch his flight. Unfortunately, he somehow managed to send my briefcase- with the iBook- sailing ten feet accross the terminal, landing onto the floor with a sickening thud. Although the iBook was fortunately in a protective notebook cover, and there were no cracks to be seen when I retreived it, my attempts to fire up the iBook have failed. That is, when turning the machine on, everything seems to lead me on that its going to run normally- the OS9 to OS10.3 transfer clicks in, I get the grey apple symbol on the grey background with the running circle below- and then nothing. The grey screen goes on, and on, and on. I tried it again this morning and it stayed like this for an hour. Worse, I cannot simply turn the machine off without hitting the reset button, and all attempts to reinstall the programs or do a hardware test lead to nothing. If I had more time, I'd probably search high and low through the forums to see if there was anything I could do to bring the iBook back to life. Unfortunately, I have to leave in two days again, and wanted to bring the laptop with me. is there some way that I can get this dear old beast running again, or is it curtains for my beloved iBook?

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.
Info:
MacBook Air, Mac OS X (10.7.4)

I have had my g4 for about two years and all of a sudden the thing decided that it's not going to turn on anymore. Power is getting to the machine and a certain amount of whirring is heard but not the signature! as it starts. The screen remains blank and would stay like that all night if I let it. The only thing I did differently before this appeared was to take it to work in a different bag a few times. Rucksack before, Side bag (more vibration).

I have recently come across an extremely cheap ibook (free) which i was able to keep if I got it too work. Well I've been successfully fairly by using it for a few weeks, then it just died. Not sure how it did but it did. The problems seem to be with the flashing (Finder/?) folder on a gray screen back ground. I've already run through the [URL] tutorials of what's wrong and have successfully done a PRAM and a PMU reset with no result. One of the times that I restarted the iBook and after the flashing folder got two new separate folders. One with an arrow turning clockwise on the left, and another folder with an arrow pointing right on the right. Both in blue folders as the flashing folders. Now I believe the problem is that the iBook is unable to find and utilize the Startup Disk. Forums I have read state to put in the reinstall disc, which I don't see how that will work on account of the CD tray not responding to anything I've yet put in there. Not trying with disc until i know that is the only possible solution. Don't want to loose my disc. Maybe some of you have come across this situation and know of a sure fire way to fix it. If not, Ill have to just send it in to some site.

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)

My ibook G4 turned itself off and when I tried to power it up the fan turns vigorously while the screen stays black. Thats it.
Prior to this I was doing some pretty heavy music importing and during that time the fan was going nuts (I then stopped importing)...also while it was charging it the past few nights the light on the connector would go out and it stopped charging while it was still plugged in. This was the first time it happened and it happened 2-3 times.
Like for most people my entire life is on that computer along with a very important document that I need to access ASAP. What could be the issue...not the logic board!

I have a 5 year old Ibook G4, which I belive just quit on me 4 nights ago. Ive had problems with it the last couple of months, like spotlight not longer working, the wifi indicatior, batteri indicator and the clock dissapeard from the top hand right corner.. and could not seem to get them turned on again. What happend; I was going to watch a movie with VLC, which kept switching itself of, I tried to restart it several times,. I then restarted the whole computer, but it would not boot up to the OS, but instead it was a black screen with a few lines written, but it did not stay on long enough that I could see what was written. Afterwards the window with MacOSX is starting up.. and the regular light blue screen. Then the MacOSX "tablet" dissapeard, and all that where visible was the light blue screen, and the mouse courser.. I could not turn up or down the brighness of the screen, nor would the volume. I restartet the machine 3-4 times but the same results. Tried the morning after, but to no use. I did download a Flash blocker program 2 days prioer to this happening, but I dont think that would "kill" of the Mac. I did try to restart it after some advice on another board, with holding the Shift button in.. this is what happend.
Darwin/BSD(m192k.studeby.ntnu.no)(console)

password:
Then I wrote some jibberish as login and password.. it just keeps repeating itself over and over again. I pulled out the network cable, and restart.. and this appears:
Uninet: monitor linkstatus, link is down
My name - ibook - g4. local (console)
Login:
Password:
Also, I held in apple+s and wrote /sbin/fsck - fy, let it run through and it said: Found 34 files, should be 35. HD was sucessfully reparied. Mac HD appears OK. Then I rebooted. all that happens is I get the light blue screen, and the mouse courser.. which works fine. What has happend to my machine? Is it dead? It's only 5 years old.. it has had such a short life.

My iBook G4 has dropped dead--the hard drive is toast, and it won't boot. I had everything backed up, and I bought a shiny new Macbook Pro to replace it, so I thought all was well. I still had a DVD in the dead iBook's drive. Does anybody have any ideas how to eject the durn thing, when the computer won't boot?

My mum has an trusty iBook G4, and finally, after ~4 years now, the battery is on the fritz. I have tried resetting PMU, but it appears the battery itself is on the way out. Is it worth purchasing a new battery for it? Or should I tell her to take the plunge and buy a low-end Macbook [non pro] to replace it?

Crucial lists PC4000 (500mhz) as well as PC3200 (400mhz) for my Power Mac. It has 1gb of PC3200 in it right now. I always thought that you wanted your RAM to be AT LEAST as fast as your FSB. Well...my FSB is 1ghz per processor. SO, would it be a good idea to run PC4000 RAM as opposed to PC3200? From what I gather if I mix them, it will just run the RAM at 400mhz. So would it be substantially faster with say, 1gb of PC4000 as ooposed to 1gb of PC3200 ?

Dual 2ghz Power PC G5 with Leopard 10.5.8Recently had it in for a repair, not with Apple (that expired a longggg time ago) because it would only turn on intermittently. They fixed this problem, citing bad components and also replaced the broken optical drive. However when they gave it back to me it was incredibly loud, they stated that they had to reconnect a fan and that was probably what caused the power problem in the first place. I'm pretty sure though that I had disconnected it unwittingly about a week after the power problem started when I opened it up to change the battery... believing that may be the problem at the time.

My iBook G4 is refusing to turn on. Yesterday it started going really slow and pressing the power button wasn't bringing up the usual options, so I held the power button to switch it off. On turning it back on it got stuck on the screen with the Apple logo and spinner for a long time so again I powered it off with the holding of the button. I then let it cool down (it was really hot) but now when I switch it on the spinner spins around 6 times then it turns itself off. It is still chiming. I'm away from home and don't have any discs - anything I can try or is it time for the Genius bar?

My iBook of six years gave up the ghost last week It's so old, I can't see any point in getting it fixed. Just wondering if it's worth selling some of the parts on eBay or the like? Airport Extreme card, battery, adapter etc.

A friend gave me one of these, said he didn't test it. i tested it but have observed the following: ring on PSU plug illuminates fine, was orange but now greed thus battery charges ok. battery button works too, pressing that initially showed 1 dot, now shows 4. charge ok and accepted. pressing the power button though, i hear the fan spin for 1 sec, the disk and the cd drive click in, but no chime and nothing on the display. no response nothing, a hard reset (hold power) turns it off. I did the PMU reset, and the pmu did do a reset, but nothing. I also did the PRAM, and again nothing. I am suspecting a faulty logic board, I hope i can get this going as aesthetically it's in good condition. For the info it appears to be an iBook G3 model A1007, If you need any more info then give me a shout.

My logic board is getting ready to crap out for the third time. I hadn't planned on wasting $$ on replacing it, but I have a friend who has an old iBook with a dead screen who told me I could have it. So, my quetion is how hard is it to switch out the logic boards? Has anyone done it? I'd prefer not to pump more money into this thing since it's probably going to die again in 6-9 months.
Also, is there a fan in the 500mHz iBooks? I'm thinking that may be the problem, b/c it's been running incredibly hot lately and have never heard the fan come on.

(I just posted this over at [URL] but figured I might as well post it here too) My Old iBook g4 1GHz, has just started kernel panicking. it wont start at all, it kernel panics my MacBook Pro when i try to start it in Target Disk mode, and it wont boot a DiskWarrior CD, or an OS Install disk i have either. I did manage to run an Apple Service Diagnostic Test CD, and it found no errors. ive booted into Single user mode, run fsck -fy and get no errors.
I tried:
/sbin/mount - uw /
and get the following message:

I have an iBook 500Mhtz PPC G3, 384 RAM, 10GB HD, Dual USB. Several months ago, I opened it up and it simply would not start up. No start up sound, no noise from the fans/HD/anything, motionless. Completely dead. I've held (many times) the PMU, and tried almost anything. Is there anything else I can do to get it to AT LEAST turn on? The battery is dead, and the charger is fine, but the battery won't charge. I tested the charger on a PB G4. I'd rather sell the whole computer as a working computer. I figured I'd get more money that way. do I need to sell it for parts?

I have a MAC IBook (800 MHz 32VRAM) ibook and when I turned it on this morning I got a blank screen. I tried turning it off and on several times to no avail. I know the computer is on because when I touch the sound button (F5) I could hear the noise, but I have just a blank screen. I am assuming its a monitor problem or did I touch a function(s) key by mistake and it blanked the screen.
