Pismo G4 550 - no startup chime after 10.4.6

Since installing 10.4.6 I've had trouble with my start-up chime not working. I have isolated the problem down to the IOAudioFamily.kext file. When I take it out of extension and boot into Classic then back into Tiger I get a chime and it stays on even if I reboot into tiger. If I replace IOAudioFamily.kext to the extensions folder I get a chime on the next boot but after that my reboots are silent. The audio function works well after the boot-up is complete only if I have IOAudioFamily.kext installed. So, I either have a start-up chime and no sound or I have no chime and normal sound. Also, when I run profiler either way I get "There was an error while gathering this information." under the Audio (built in) tab. I've tried taking the IOAudioFamily.kext off the TIger install dvd and using it instead but I get the same problem as before. There must be some sub-extension or something that was changed to cause this. Does anyone have any suggestions besides live with it?
I've tried the PRAM reset thing and its doesn't work.
Thanks

When
booted in 10.4.6, do you always get the startup chime
through a restart? If so, then the difference lies
with the cold start versus the restart and there are
a few differences.
I lose the chime whenever I boot into Tiger and let it run to the log-in page. When I safe boot the chime is preserved but the os doesn't recognize my built in speakers and the volume control disappears. If I boot into OS 9 the chime is still gone until I shut down and power up or reboot, then the chime is back. So, my thinking is that there is a kernel extension that enables Tiger to see my IO card (built in speakers and headphone jack) and it must turn off the speakers from the system somehow. The OS 9 startup must unhook the IO card from the driver and therefore allows it to chime when no driver is present.
A cold start runs the POST (power-on self-test); when
powered on, the Start Manager, contained in ROM,
makes sure that certain hardware components on the
computer's logic board are working, like the
microprocessor, ROM, drives, ports, expansion slots,
and RAM. When you hear the startup chime, the Start
Manager has successfully completed its test.
Open your System Profiler > Hardware > Diagnostics
and see what the last POST reports.
OK, this is weird. When I go to profiler and look up Diagnostics it says "No information found" but you say that post should give some sort of account.
On my iMac G5 it says:
"Power On Self-Test:
Last Run: 6/12/06 8:17 AM
Result: Passed"
I think that means the boot ROM on the pismo (boot rom version 4.1.8f5) isn't talking to the system profiler log.
Just another tidbit: Audio (built in) says "There was an error while gathering this information"
No error code.
This smacks of a firmware issue. Do you think there is a firmware update that would fix it?
I don't know what else you can do. If it is in fact
strictly a software problem (which I cannot explain
since software does not begin to load until after the
startup chime), I would not be concerned. The other
test you could perform is removing the added
RAM...maybe OSX has a small problem with the new
memory module.

Anyone notice a delayed or a missing boot chime after Performance Update?

24-hours into this Performance Update, and I either get a delayed boot chime or nothing at all.
Anyone else?

Having spoken to an Apple product specialist, I have learned that if you have not been hearing the boot or startup chime after having installed the Performance update, download the update again from the following URL, and install it again. This will correct the installation and restore the boot chime.

Make sure that you check your graphics selection under Energy Saver in System Preferences, as the Performance update sets graphics to the default setting of Better battery life.

No Startup Chime on Pismo

I'm trying to figure out while after installing Mac OS X 10.4.6 on my Pismo, why it would not chime at startup, does anyone have any ideas?
Thanks in advance.
PowerBook G3 (FireWire) Mac OS X (10.4.6)

LyonAdmiral:
I am sure you have checked to see that the sound is on (or the mute is off), but just in case.
Try resetting the PRAM (from a cold start hold down Command + Option + P + R while you hit the power button. Hold for 3 to 5 chimes then release). One of the things reset is the speaker volume.
Good luck.

TS1367 My PowerMac G5 will not start up. There is no startup chime, no display and the fans speed up and sound like and airplane after about 30 seconds. Can someone help?

I push the power button, and it turns on, but there is no startup chime, no video display, and after 30 seconds, the fans spin up. Any ideas?

G5 has these hardware issues:
-- bad capacitors on logic board
-- bad capacitors in power supply
-- badly soldered video chip
-- "There were several Mac models with flat panel displays that had bad displays.
     Most had serial numbers beginning with "W8"---the code for one specific factory.
     This affected PowerBooks as well. If that's the case, the rest of the computer
     is probably fine." by Allan Jones in

Quicksilver shuts down after startup chime

Hello,
I got an old Quicksilver 2002 (933) which won't boot : it shuts down 3 or 4 seconds after the startup chime. What's wrong ?
Thanks

Thank you for your answer, but it didn't work.
I forgot something important in my first post : the story of this Quicksilver
So yes, I just acquire this Mac, didn't work at all. It was missing a screw on the CPU card. After adding the screw, the PM booted into my Tiger DVD. I shut down the PM to close it correctly. It didn't boot anymore for this time.
I tried PRAM reset, motherboard reset. I've taken apart all I could (modem, graphic card, hard drive, ...), I've replaced the PSU, but nothing. I noticed that when I try to boot without RAM, the powermac makes one beep (no RAM installed) but don't shut down after that ! So I tried with 2 different RAM modules on every RAM slot, but it didn't work. (each RAM module is PC133 and works fine on my iMac G3 DV SE).
I think the motherboard or the CPU is screw up, but which one ? Maybe I forgot one thing to make it work ?
Cheers, Aurélien

MacBook shuts down about one minute after startup chime

I have an older (2007?) Macbook, and I think it is running OS X Snow Leopard (10.6.3). I can't verify this because it won't boot up. It does the same thing whether on battery or ac power: startup chime, grey screen with apple logo, twirling spokes, and grey bar filling in. Then, exactly one minute and 38 seconds after the chime, it goes black (keyboard and everything).
I have tried unplugging and waiting, starting with and without the battery, resetting PRAM (tried that a bunch of times), and starting in safe mode with shift (doing that caused it to shut down in 1:08).
I have two disks that came with the MacBook: OS X Install Disc 1 and Disc 2 (2007; v10.5), plus one disk Mac OS X Snow Leopard Install DVD. If I should try rebooting or reinstalling, which disk(s) should I use?
Or is there another trick to try?
Thanks!

Try this support article > Mac OS X: Gray screen appears during startup
Boot from the Snow Leopard disc following the instructions from that article.
While you have Disk Utilty open, check the S.M.A.R.T. status at the bottom of that window.
Hopefully it says: Verified

MacBook Pro keeps shutting down immediately after startup chime

I booted into Windows 7 on my boot camp partition and was about to play Dirt 3 for the 1st time. I was in the options menu of the game and my MacBook Pro just shut down/turned off instantly.
I turned back on, holding in Option so I could boot into Windows again, but the computer just turned off immediately after the startup chime. I turned on again, this time I didn't hold in Option, so I could boot into OS X (my default startup volume) and the same thing happened - MBP shut down immediately after the startup chime. I tried again, same thing. I tried again, and this time it booted fine into OS X, and all seems ok.
Any idea what's going on?

Hi. When you were in the recovery drive doing permissions, did you try and run a repair of the boot drive? Did you try single user mode? Try these first and then go back and try to reinstall the operating system.When I say repair boot drive I don't mean permissions. There are both options in disk utilities.When you open disk utilities ,you will see in the left column two drives plus possibly a boot partition that look like an external driv. click on the second drive and in first aid use repair disk. If you still can't boot and it will not let you restore, you may have to do a clean install. http://support.apple.com/kb/PH18869?viewlocale=en_US

Re-Start Issue: Chime Echo after startup chime ??

My 20 Intel Imac running OS 10.4.9 has developed a minor problem related to its startup sequence and I suspect firmware startup instructions:
When using the control panel startup disk dialogue to reboot from Windows XP back into OS 10 I get a repeating shorter echo of the familiar startup chime and the machine will not reboot into Mac OS until I hold down the power key at the back and force it to.
Similarly, altho with less serious effect, the machine echoes its startup chime a second or two following the normal restart chime when in OS 10, but in this case it des then reboot normally.
I suspect a corruption of firmware or NVRAM but I am unable to force a reset of NVRAM by holding down COMMAND-OPTION-O-F during restart. This works on a PPC G5 but does not seem to reset NVRAM on an Intel-based Mac.
Any suggestions from the list as to the cause and fix for this strange echo of the startup chimes ??

A NVRAM or PRAM reset is accomplished with Option +  + P + R.
Startup key combinations for Intel-based Macs
The startup chime is an indication that your RAM is OK and the Mac has passed the Power On Self Test. You might try reseating the RAM modules.

Mac Mini won't boot, distorted startup chime, gray screen

Hi all --
I've seen similar posts (http://discussions.apple.com/thread.jspa?messageID=12170891&#12170891) but thought I'd start a new one, mainly because I haven't heard anyone mention the startup chime.
I woke up my 2007 stock Mac Mini Friday morning and the cursor was frozen. Unplugged and replugged the mouse to no avail. Couldn't force quit, so I had to power down. Restarted with a badly distored startup chime (not "speaker breakup" from excessive volume, just distortion, and some "stuttering") and a gray screen that didn't go away. Restarted many, many times. Inserted Snow Leopard DVD to run Disc Utility but it wasn't recognized -- just a gray screen. Tried resetting the PMU and SMC with no results. Tried booting into single-user mode (with a wired USB keyboard) to eject the DVD, but no luck. Tried open firmware, but nothing. Once in an while I would get the Apple icon and a spinning progress bar that never went away.
Took it to the Genius Bar, where they tried to boot from a Firewire drive, with no success. The best they could do was tell me my 17-month old Mac was out of warranty. That confirmed, I took it home, cracked it open and removed the Snow Leopard DVD (with a credit card) to insert the install disc it shipped with. That didn't work. A couple of times it looked like it would, but then after the spinning bar I got the multilingual system bomb message. Tried to run Hardware Test, but nothing. Put in original Disc 2... and that gave me a flashing folder! Progress! Forced the DVD out and slipped in Disc 1. That started to read, and then I got some kernel-panic looking text and a shutdown. My last attempt was to create a USB boot drive from the original install discs, but my old Sawtooth won't let me run the installer.
Is there any hope at this point? I just bought the thing last May, so I've had it less than a year and a half. The distorted startup chime makes me think the logic board is fried and no amount of fooling with the startup drive will make a difference. The only thing out of the ordinary in this case was that it went to sleep last Thursday night with a DV camera hooked up via Firewire.
I'm not thrilled about giving Apple any more money for another Mini, but I'm heavily invested in Logic Studio so I don't have much of a choice of platform.
I'm pretty sure I'm doomed, but I thought I'd post anyway. A quick internet search shows I'm not the only one with the gray screen of death on a fairly new Mini. Thanks in advance for any pointers.

Thanks.
The Genius was able to get to the Apple logo and spinning... thing (what used to be the beachball). His theory was that as long as the Snow Leopard disc was in there, the boot process would never get to the Firewire port. Once I got home I literally pried the Snow Leopard disc out and put in the original install disc. But any progress whatsoever ends in the system bomb message.
Thing is, I had tried to eject the disc by booting with the mouse button down. But on restarting, the laser in the optical mouse flashes quickly, once. I don't think the USB ports are going "live" at all... so I can't get into single user mode, safe mode, hardware test, anything. The Genius' keyboard was no help in that regard. So yeah, I suspect a hardware problem.
A search of "gray screen of death" shows this happening to a lot of models.

Mac Mini won't boot, repeating startup chime

This afternoon I noticed that my Mac Mini (1.5 GHz Intel Core Solo) was acting sluggish. I opened up activity monitor and saw that the process 0 (kernel_task ?) was using about 50% of the CPU. Assuming that it was in the middle of something, I left it alone for another 10 minutes. Still 50% red in the CPU Usage graph in Activity Monitor. I then turned the computer off. When I turn it back on, I get a gray screen, one normal startup chime, followed by somewhat quieter startup chimes about 1 -2 seconds apart. I've tried resetting the PMU, starting up with no USB connections, safe mode, by CD, etc. I don't think the keyboard is even recognized. I know that works, because I tested it on my laptop.
Any suggestions?
Thanks!

OK, well it would not make any difference that the install disk was already inserted - as long as the Option key was being held down at the right moment, the system would go into the boot loader screen even if there were no bootable volumes.
Make sure the Option key is down immediately you hear the first chime. If you've been doing that, it would be an indication of a more serious fault.
Try an SMC reset to make sure the system hasn't just corrupted the management controller, then try again.
An SMC reset can be accomplished as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
If that doesn't work, there's a hardware fault. In which case the nature and pattern of sounds you hear after the initial chime may be the clue, since these may be the system giving an audible report from the power-on self test. Are these regularly repeating beeps? rather than chimes? If so, you should hear a pattern of 1, 2 3 or 4 of them followed by a second pause, then repeating.

No startup chime, red light, fans running loud...

yeah, I know that there are other threads with the same topic, but I just wanted to know how common this problem is?
How many people have experienced this?
What are the common disturbances?
What is going on?
Why is such an expensive, powerhouse computer become such a puny electronic product because of power issues?
I posted this in another thread but,
Here's my story:
I am having the same problem.
Now before you start taking advice to back up all your data, reformat your hard drive, and reinstall all the software; please take note of a few things:
first off, I'm ****** that this is happening to me. I spend $5000+ for a "reliable" Apple computer. Then it doesn't want to turn on because its not safe. Sorry if I drown this post with bitter sarcasm but I am coming to the end of the line with my patience.
I called Apple Care, read a bunch of posts (here and elsewhere), and yes I do know about the SMU Reset button (like that really does anything?).
My problem happened a few weeks ago and I thought nothing of it at first. There was a power outage for a quick second and it turned everything off. When I went to turn on my computer, there was no chime, the red light was on, and the fans were running and eventually began running very loud. After letting it run like that in hopes of the screen lighting up, I turned it off by holding the power button. By the way, there's nothing on the screen and the keyboard doesn't work (I use a wireless keyboard, but I plugged in the OG cord keyboard to push whatever series of buttons recommended by these "geniuses") Trust me, the computer doesn't make it to that part of the boot process, so stop with commandoption+PR or F12 to get the CD out. It doesn't work! What's up with this computer! It can handle all these intense calculations,etc. but a power surge is going to shut it down indefinitely.
So I left the computer came back the next day, turned it on and its fine. Cool, I'm happy. It's Working!! I go on a few weeks, then I go to turn it on this Monday, same problem. But actually a worse situation. I had a client come over and the computer wouldn't work. I looked like a idiot. Couldn't do anything cause my computer didn't want to turn on. I do music production/editing. I use my G5 for running ProTools LE. I have other programs but that is the main one I use. There's nothing wrong with it. It's optimized for use with the mac. So those people who are going to advise me to uninstall all my software and all that - I appreciate your concern but don't give advice when you don't know anything!
So I am getting frustrated. My client left a little disappointed, but what can you do? I tried to call AppleCare on Mon. but it was Memorial Day. So I waited for Tues.
Tues morning, my computer turns on like everything is fine.
I'm happy but cautious. I talk to AppleCare rep. He tells me that it is a common problem they have heard about with the G5's. Wherever blackouts, brownouts, spikes, sags, dips, and other electricity inconsistencies occur, the Power Mac G5 has a breaker in it which flips so it doesn't receive uneven power supply and damage internal components.
I like that feature. Good thinking Apple. Protecting my investment from bad electrical grids. But I don't like the fact my computer has a mind of its own where it decides when it wants to boot or when it wants to sit there and run its fans all loud.
I shut down Tues morn to go to work. I come back in the evening, it doesn't want to boot up. Instead of getting angry trying a bunch of times to turn on/turn off the computer, I leave my house all together and go and have a few drinks. I come home ,don't even look at my computer, and go to bed.
I wake up Wed. morning. Go to turn on my computer. Successful boot. It's running. Okay, I think, I'm going to get down to the problem. I read all the logs, not like I know every piece of info, but just to see what's happening. Everything looks fine. I decide to run the AppleCare CD Tech Tool. It says restart holding down C. I do that. When the gray Apple Logo comes up, all this writing about kernals comes up and it tells me to restart or shutdown. I shutdown and attempt to restart, same problem: no chime, red light on, and fans eventually spin loud. Now the CD is stuck in there. I'm going to take it to the Apple Store tomorrow to if these "geniuses" can figure it out.
(Just a side note: Apple calls them geniuses, but its hard for me to think some disconnected college kid with a bad haircut and questionable social skills knows what's up with the power supply issues of a computer; maybe I'm wrong, but you can run your diagnostics and look at the chart of what to do and all that BUT Apple needs to listen to the people)
I am going to get a UPS (uninteruptable power supply) with a clean sine wave output to curb the issue at my end. It's not my fault I live in a area that receives uneven power output. I live in Los Angeles. Summer is starting up and I think its going to be hot, so blackouts, power dips and sags are inevitable. I just don't understand why Apple hasn't considered this problem and fixed it with something:
A recall to change the power supply, Is it something on the logic board?, are they going to reimburse me for lost income (Ha, yeah right)
I really want to know how many people are having this problem?
From what I've heard, it is a common problem.
So I think we need a common solution.
If its so common, it must be the computer. We are all going to live in different areas where the power may vary. Not all of us have the consistent power flow of 1 Infinite Loop in Cupertino, CA. So if it is such a common problem, Apple needs to fix it.
I can't spend more than five grand on a super duper computer and have it wuss out on some power issues.
Its a loss of income and productivity to me.
I can't have that anymore.
Sometimes my computer turns on, sometimes it doesn't.
I bought my PowerMac G5 in April 2006, its been about a month and a half and I'm having these problems.
Thank you for your time.
If anyone else has been having this problem, I feel for you.
It was been very difficult for me not to curse in this post, but I have tried to extend the same respect to all that use these discussion boards to create dialogue, find help, and create solutions.
LETS FIX IT!

Well, you can see my specs below. I have the same problems as you, just worse. I am also running (as I have my previous systems) on an APC Smart-UPS 2200, and it doesn't solve this problem.
I bought my machine last December. In early March (just 2 days before my 90 days of phone support were up), I woke the computer from sleep to check email; about 5 minutes later it just froze. I had to force it down, but it never even got to the startup chime.
Called Apple, bought Apple Care on the spot, spent about 45 minutes on the phone with two levels of support, and Apple couldn't really diagnose the problem. They decided to send out a replacement logic board, processor unit and power supply for on-site service (I don't have an Apple service center nearby).
Nearly two weeks later the technician arrived with the parts, installed all of them, and - nothing. The system still exhibited the same symptoms as before the repair. He spent around five hours here, most of it on the phone with Apple. They decided that the processor unit they shipped was defective, so they sent another processor unit.
Nearly another two weeks later, the re-replacement processor unit arrived with the tech. He installed it, and everything worked. This was around April 1.
Fast forward to last Wednesday. Arrived home from work, tried to wake the Mac. Nothing happened. Had to force the machine off. Never booted again. Called Apple and went through the motions again. They're sending another logic board, processor unit, and power supply.
I asked about having the machine replaced since this will be the third repair attempt, considering it took two visits and nearly a month to repair it the first time it died. Apple was unwilling to replace it but I was told that if I had another failure, a replacement would be in the cards.
I agree with you about needing reliability in a computer as expensive as a Power Mac. It is not acceptable to have this kind of failure, repeatedly, with this kind of system. If my Windows PC has a hardware failure, I can take care of it myself. A top-end power supply is ~$200, a quality system board is ~$200-$300 - all very doable, and in very little time, if the need arises. A Power Mac logic board is ~$1K, a cpu module is well over $1K, who knows how much that crappy power supply costs, etc. If you have Apple Care, you face the kinds of downtime I'm having to deal with. A month without use of your computer. I mean, if I buy a Dell workstation, or an HP workstation, and pay an extra $200-$300 for service and something fails, Unisys will be here the next day and it will be fixed. That's the standard business class service experience you get from those companies with a computer that costs $600, much less the $3000+ you dish out for a Quad Power Mac. Apple's response is unacceptable.
It's a good thing I have kept my Windoze machine around, cause it's really saved my butt the last 2-3 months; that also makes me really sad, because in the last 6-7 years of Power Mac ownership I've had zero problems with any of them. My dad has my previous machine, a Rev A Dual 2.0 G5, and it's rock solid.
I sure hope that the Intel based Power Mac replacement doesn't suffer from what ever seems to afflict the recent Power Macs. I would absolutely hate to abandon OSX, but I will not put up with this kind of quality failure (hardware & service) again.

No startup chime

I have a 1.25GHz powerbook that has been acting up for the past month or so and being a teacher I have not had much time to do anything about it and now that school is out for the year I have spent the last two days working like crazy on it and one thing occured to me. I have not heard a startup chime in a some time. So, after looking around on these boards I see it might be due to a logic board failure. Sure enough, after looking under system profiler/diagnostics, it showed "no information" So, I powered down, removed the battery, opened the ram door. I pulled out both sticks, (a 1 gig stick, and a 256 stick), swapped their positions and restarted. After checking diagnostics again, it showed a P.O.S.T. of failed!!!! Failure type is memory.
So, I removed a stick memory and tried to boot - it just beeped at me - so I guess that confirms I have a bad logic board???
The good news is that I have applecare, the bad news is that it expired on 5/24/07, and today is 6/02/07 - is it possible Apple would be flexable regarding this issue?

Welcome to the Apple discussions.
Sometimes vendors will effect a repair for something just out of warranty, on a goodwill basis, not because they are obligated to. As Joe suggested, either write a letter, visit your local Apple store, or talk to Apple customer service to see if they would do a repair. Perhaps, due to your job and timing, they'll consider it, however, if they tell you no, you'll have to pay for the repair, that should not be a suprising outcome.
Others have done what you described, which is to put a 1GB stick in the upper slot, and run that way, in lieu of replacing or repairing the board. There are one or two companies that claim to repair the board, if you do a search on the discussions you'll find them, if you want to go that route.

G3 B&W - No startup chime

This is strange.... When I first started working on this G3, there was no startup chime. I plugged in a auxillary speaker system into the headphone port on the back, and was able to get it for a few times until it stopped through there....
I had problems with this system starting until I had to had to reset the system (CUDA for 30 sec and Zapping PRAM). I then lost the sound......
I have alert sounds through the front speaker, but no startup chime......

startup chime has been known to disappear randomly and reappear equally randomly. I think I got mine back once after running combo update for an unrelated issue.
Unless you need the cue for pressing a startup key (ie- booting from optical drive, safe mode) i wouldn't worry about it. Even without the chime you can pretty much time that just right.
If it really bothers you search the discussions for 'startup chime' and sort through the myriad of reccomendations until you find one that works. Personally i wouldn't worry about it.

Startup Chimes with audio cable connected?

My Mini has started to sound it's healthy startup chime even when there is an audio cable connected to the audio/headphone output. The output works fine and sends audio to the speakers, but how can I mute the chime at startup?
Previously it always muted that sound with a cable connected and I believe it started chiming when I updated to 10.5.4.
TIA.

The mini generates the startup chime via the internal speakers regardless of whether external speakers are connected or not - the necessary support for the hardware audio port isn't loaded until after the power-on self test (which is what generates the chime) so in common with the iMac range, the chime comes from the internal speakers.
The only way to mute the chime at startup is to set the Sound preference pane to Mute (check the 'Mute' box in the Sound Effects tab). There are also some utilities such as Startup Sound (http://www5e.biglobe.ne.jp/~arcana/index.en.html) which variously succeed in muting the chime, though these tend to get broken with MacOS updates.
