G4 MDD (fw400) - doesn't give startup chime - any troubleshooting ideas?

Just bought unit off ebay... prev owner said it was running.
Hi power button - no chimes.
_ Fans turn on high after about 10 seconds.
_ Red LED near memory sticks is on.
_ Reset PMU, put in battery from the 500 Mhz Gigabit ethernet G4
Any other ideas?

Hi-
Welcome to Discussions!
I assume the machine was shipped to you?
I would reseat all memory, the graphics card, and even reseat the CPU.

G5 Won't Boot or give Startup Chime, just pulses Power light 3 times

My G5 Will not boot.
Instead all it does is the power light stays on and pulses 3 times in a continuous sequence.
I assume that this '3' pulses must mean something.
Has anyone any ideas on what this means or how to debug this issue?
I tried starting in Safe Mode Control/Option O F but nothing.. the monitor doesn't even initialize.
Any help would be appreciated!
Thanks,
Steve

I hadn't heard of the lead free solder issue. So I browsed around this forum and found lots of discussions on the subject..
I think that this maybe the problem.
I'm guessing that when I pull and reinsert the memory cards then I'm flexing the circuit board around the memory slots slightly, and making contact on a dry joint. Then with heat expansion the dry joint is opening up again..
Does this sound plausible?
Now for a dumb question.. I have my two 1G memory cards in slots 1 and 1 in my 2G G5. Assuming that the dry joint is around slots 1 and 1 then would it be possible to move the memory cards to slots 2 and 2. Would the G5 be smart enough to detect the cards and reconfigure the addressing? ..
Its a long shot... or maybe I'll just try it? :-)
Thanks,
Steve.

TS1559 i do have exactly this problem - but this resolution doesn't work at all - any other ideas?

WLAN as well as Bluetooth stoped working after update to 7.0.3

Final Cut Express was discontinued about 18 months ago, before the release of Lion (10.7). It is no longer a supported product and was never supported on Lion, nor on Mountain Lion.
While some FCE users have had success running FCE on Lion, many have reported problems including problems with chroma keying. I do not recall any solution to the chroma keying problem, but you might try searching this Forum to see what others have discovered or tried.
Final Cut Pro X is the app supported on Lion & Mountain Lion, and the future direction Apple has taken. Since your computer lab has already moved to Lion (10.7.5) and presumably will move to Mountain Lion in the future, you should begin the process of moving to Final Cut Pro X. I appreciate there are implications for cost, training, inconvenience and re-doing lesson plans. But technology moves on and at some point we need to move with it too.

MBA repeats startup chime but doesn't boot up. Why?

MBA timed out while Applejack was running then shut down and now repeats startup chime but fails to boot up.

And exactly what MBP model do you have? What version of OS X is installed? What version of AppleJack did you use?

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!
Peace,

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.

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.

How can I turn off the startup chime?

The chime sounds from the internal speakers at full blast no matter what volume I have set the computer to. Is there any way to turn this off or at least quiet it? It keeps waking my baby up, even when she's sleeping upstairs!

Julia,
I have used the System Preference pane that Neil recommended for over a year successfully. It is good to hear the startup chime, even at a much lower volume, because it lets you know that your Mac has passed the built-in Power On Self Test.
I'm sure that mr fish didn't mean for his post to be as condescending as it seems. You know, telling a woman where her mute key is located! He is new here in the Intel discussions and has been having issues fitting in. He recently learned how to color the text of his posts and isn't aware of how childish and distracting they have become. But he is coming along and is a welcome new personality here in Using Your Intel-based iMac.
But, mr. fish aside, the tip he gave you about muting your Mac before turning it off should work! So the fact that you report that it doesn't, leads me to believe that there may be some maintenance issues with your new Mac. I want to give you the link to the X Labs. Dr. Smoke, the author, is a long-time, regular contributor here in the Apple Discussions and he has put together a great site that explains well how to keep a Mac & Mac OS X running in good condition. When you have time you can check it out and see if there are some things that you could be doing that will keep things running smoothly.
Something that will help folks here in the forum when you ask for advice is if you go to your Profile and expand a bit about your Mac; model, OS X version, amount of RAM, etc.

Mac Pro - Holding option doesn't display startup manager

I have a late 2008 Mac Pro, Ive been running OSX 10.8.5 and Mavericks (on separate partitions). Now out of nowhere holding down option doesn't bring up my startup manager. I can access both OS's by changing the startup disk in system preferences, but I'd love to get the startup manager fixed.
I have tried reseting the SMC (by unplugging it for like a minute) and resetting the PRAM/ NVRAM by holding down Command + Option + R + P; however resting the PRAM doesn't seem to be working. The startup chime happens once and then after about thirty seconds it boots into the recovery partition.
Thanks in advance!

I had this problem with my 2009 Mac Pro with OS X Yosemite. The problem was fixed for me after removing two of my ram sticks, resetting the PRAM three times in a row (wait to hear chime, then wait for restart, do this three times) and booting up. There are some additional firmware settings that are reset when you remove ram. I replaced the ram, and now my startup disk menu always appears. Googling "how to reset firmware password on mac pro" will give you solutions that also solve the missing startup manager problem. Best of luck to you!

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.

Hello sallay Amir,
Thanks for participating in the Apple Support Communities.
It sounds like you would like to erase your MacBook Pro and install a new copy of OS X, but the Mac does not boot to OS X Recovery when you hold the Command + R keys during startup.
If your Mac came with OS X Snow Leopard (10.6) or earlier, I recommend referring to the steps in this article:
Mac OS X v10.6 Snow Leopard: How to Erase and Install - Apple Support
For a newer Mac (OS X Lion, Mountain Lion, Mavericks or Yosemite), try reinstalling OS X by using Internet Recovery, as described in the "OS X Internet Recovery" section on this page:
OS X: About OS X Recovery - Apple Support
All the best,
Jeremy

G4 startup chime=ok, video=no, keyboard commands=no

Hi everyone.
I have a dual 1ghz mirror door G4 that stays on most of the time. Last night it was working fine but this morning it wouldn't wake from sleep so I shut it off by holding down the power button. It will occasionally freeze at night, so this didn't seem to strange. Now though, it makes the startup chime and the fans (and maybe HD) makes some noise, but no video displays. Startup key commands are also not working and I cannot get the cd drive open (it is empty now), but even if I could get a disk in there I couldn't get it to boot up without the keyboard working.
So far I have tried:
unplugging all peripherals
leaving everything unplugged except the keyboard and monitor
removing the battery
resetting the pmu
removing non apple ram
resetting pram doesn't work
Does anyone have any suggestions? I really appreciate your help.
Thanks,
Rob

Well, no luck with inserting the Tiger install cd and disconnecting the hard drives. Like I said, everything sounds normal when starting up the computer, the fans go on and you can hear the hard drives and cd spinning.
I have tested the keyboard on another computer and it is working, but when starting up the G4 eject, resetting PRAM, cmd-c, and cmd-t don't work. The monitor as well sits idle (with the LED yellow) when you disconnect the monitor cable it turns green and says no signal and check cable. Once you reconnect it it goes black again with the LED changing back to yellow.
The startup process is initiated by the firmware and therefore regardless of having a functioning OS, hard drive, or cd drive, something should come up on the screen and key commands should work.
Hopefully this isn't something major like the motherboard going out or something similar. I am certainly no hardware expert, but it seems like something along those lines.

How can I turn off the startup chime on my new iMAC (Intel based)?

Hi,
Every time I turn on my iMac the startup chime is very loud. It doesn't matter whether I lower or mute the volume prior to shutting it down, the startup chime volume is unpredictable. Is there any way possible to control it without having to download a third party program?
Thanks!

Thank you for your response.
I seem to get a lot of conflicting information whether you should shut down a computer at night or simply put it to sleep. However, that is another discusssion
As to the startup chime, ideally I would like to be able to control the volume at least (not mute it). I will still be able to hear the chime when the iMac starts up, but right now it sounds like a church bell going off in my apartment whenever I turn on the computer!

Controling Startup Chime

How can I control the startup chime? My MDD speaker is trashed and the audio level is WAT too high so it sounds awful! Is there a way to turn the volume down, mute or switch it to an audio output?
TIA,
B.

Don't want to have to remember to turn my audio all the down after each use. There must be another way to control this.... Anyone?

Mac Mini auto shuts down shortly after startup chime...what should I do? Thanks.

Our boss brought a mac mini model A1176 from the US to be used by her staff here in the Philippines. We powered it up- everything was working. Then it just stopped working after onen day. Whenever it is powered up, the mac mini auto shuts down shortly after the startup chime. What's wrong. How can we fix it? Thanks a lot.
