IMac Summer 2000 G3 won't start up. No green light!

Our beloved old iMac (listed below) has simply died on us. The green power light won't light up and we get no sound when it's pressed, nothing. At first it blinked then shut down and now won't blink anymore. All I get is a blank screen as if no power was booting up. A power cable check and replacement didn't help.
Recent history: We frequently got problems with the date and time. I had always isolated that issue as a weak PRAM battery. We got an error message that the date was wrong i.e., Jan 1 1971. An attempt to correct it didn't help. The error message said that the PMU needed to be updated. We downloaded some Apple software but it turned out it was for 0S 9. Yesterday we had some issues such as the iMac wouldn't shut down and woud suddenly go to sleep instead. Then today it just wouldn't start up, period.
My suspicion is it's either the power supply or the PRAM battery. But the battery is only 2 years old and normally their life span is longer than that. I have an old Mac IIVX with a PRAM battery I can dig out of it. This is my first workaround.
I know others here have recently posted similar problems and this may sound redundant, but I'm doing the workaround and will post the results. If anyone can conjecture on this battery issue or if that fails and you think it's the power supply then please let know where I can get a new one. Otherwise I'm going to try to find one on Ebay.
Thanks

James,
Thanks for the update. Was the quote from an apple authorized dealer? <--
I was quoting in euroes which is higher than dollars. I'm not sure what the euro to dollar rate is now but the dollar is pretty weak. I live in Europe, shoulda mentioned that. The weak dollar keeps all Apple products relatively low and has for the past decade or so. And yes it was a local authorized Apple dealer, not a box store. I've looked at them and their prices are a bit higher and you don't get the reliable warranty service. They've got the Apple trademark selling area but walk a few yards and you can get a Dell. I think Apple rents them the space, but most people I know buy at authorized Apple dealers where you can customize your order and have good service on warranty. I don't have an official Apple Store here, I wish I did but sofar there aren't any in continental Europe I know of. Maybe one in London.
For the iMac G5 17in 1.83 MHz with 512MB RAM 160GB HD and no Superdrive the asking retail price is around 979 euroes. The 2MHz Core Duo with 1GB RAM, Superdrive and two FireWire 800 ports goes for around 1,117 euroes. The 20in starts around 1,300 euroes.
Also have you thought of replacing the board yourself? <--
My wife just shrugged and decided to break down and shop for a new one. It's too much bother to do a DIY repair that big. We figured we could salvage some of it for its parts and resell them on eBay. I stole some RAM and the fresh PRAM battery out of it for my G4. The HD will be removed and wiped. Maybe resold. I've seen a G3 motherboard on eBay but you don't know what you're getting. I stop at buying used RAM and power supply units.
Post a new post for instructions and parts locators if interested. <--
eBay USA has a full range of Mac parts. I saw a G3/G4 power supply unit that was going unsold for $12 today. Could use that to fix up the Blue and White but the shipping to Europe is $35 and I can buy one here on eBay for 45 euroes plus shipping.
Thanks,
Rob

SNOW iMAC DV 500 mHz won't start

I upgraded to 4.1.9 and installed 10.4.6 so I could run new software.
Worked fine until several Power failures by Edison this week. Now will not restart from the button on front; not even a tone; just a click and flash of light sometimes.
Acts like a latching relay isn't pulling in. I changed to new 3.6 v 1/2 AA battery; zapped all the things listed and still not even a flicker from the screen; sound from the drive; etc.
thanks for help

IMac 20in intel2.66gh won't start up!

My iMac 20in intel 2.66gh won't start up. When I turn the power on the screen stays black and a tone sounds 1-3 times at approx 2 second intervals. Does any one have any solutions I can try before I pack it up and take to my nearest apple store. Thanks. Merilee

Could be a RAM problem: http://support.apple.com/kb/HT5860?viewlocale=en_US
Before taking it to the workshop, you could try unplugging the modules, cleaning the RAM bay with a vacuum cleaner and then re-seating the chips. It's an easy thing to do - Youtube has plenty of 'How to's'. Make sure the Mac is switched off and unplugged first.

27" iMac 3.2 i7 won't start. Emits 3 'beeps', pause, repeats.

My 27" iMac 3.2 i7, 20GB RAM won't start. Emits 3 beeps, pause, 3 beeps, pause.

Here's a link to an Apple support page that describes the possible Startup tones.
Mac computers: About startup tones - Apple Support
The short answer is here. Looks like your RAM is bad.
1 tone, repeating every 5 seconds: This indicates no RAM is installed.
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
1 long tone while holding down the power button: Indicates an EFI ROM update is in progress on a computer manufactured before 2012.
3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.

HELP! My Mother in Law's IMAC - OS 10.3 won't start in safe mode!

She had a power outage last night, with the computer on. She just gets a screen with the apple and spinning gear. We can't start it in safe mode or with the install disc. She got something when we started up in single user mode, but she said there was no place to type in any commands - just lots of writing that does not make sense to us. PLEASE HELP!!!!!!

sciteacher77:
Here are three articles from Apple's Knowledge base dealing with different startup issues. Look through the first two and see if they offer any help. Then go to the third and see if you can get it to work.

IMac G5 (iSight model) won't start up - video included

http://s1212.photobucket.com/albums/cc449/langdonX1/?action=view&current=imac071 .mp4
An imac 1.9Ghz G5 won't boot up at all. When you press the power button you hear a sight whirr and then a faint high pitched hum. Sometimes the power light turns on for a second in unison with the attempt. I tried to reset the SMU but that did nothing.
I took the cover off and saw nothing obvious wrong.
At the 3 and 8 second mark in the video you can hear the sounds it makes but you may have to turn up the volume.
Is this symptomatic of a dead power supply or some other problem? Any solutions to get it working again?

from your linked article:
This article does not apply to iMac G5 (iSight) computers.
iMacs with an iSight have no back to them. You remove the face of the computer to access the logic board and the screen has to be removed to get to that. So all that stuff in the apple knowledgebase article can't be done to this model.

My Mac Mini won't start. The Power light blinks continusly (not pulses)

My New Mac Mini won't start up. I bought it online from J&R a week ago. My monitor says "no input detected" and the power light blinks. I recently fed it the gray mac os x install disk one, which it won't give back. Holding the mouse button when it turns on doesn't have any effect. So now i can't put a disk in or start it up.

Welcome to the Apple discussions.
No video with the power light blinking once per second means either bad or no memory. See this Apple note: http://docs.info.apple.com/article.html?artnum=303083 . Specifically, below is from that note:
If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed.
Has it ever worked since you got it? If not, you should call J&R and tell them they sent a dead on arrival system, and ask for a replacement (ask them to send a will call tag or prepaid label to send the non-working machine back).

Won't turn on, shows green light

So last night I was playing with my phone, using up the battery, then it notified me that the battery was low. I stopped using it and just turned the display off and put it in my pocket. I went to my room and I tried to turn the display on, it didn't work. I assumed it died so I plugged it into the WALL charger. It showed the green LED light on the top of the phone, but it still wouldn't turn on. I then just went to bed and let it charge ALL NIGHT. I woke up to see the Motorola symbol on, and it was booting. Then I went back to sleep. Then I woke up later and it was the same as before, it wouldn't turn on, and the green light showed when you plug it in.
I've tried leaving the battery out for a few mins, taking the battery and SD card out and putting them back in, I've tried just letting it charge, nothing is working.
Also when I plug it into the computer via USB, it shows the green light as well, but the computer doesn't even notice it's plugged in. The computer doesn't respond to it being plugged in what so ever.
I also did some re-search before posting this! Looking at forums where people at the SAME problem, and none of their solutions are working...

Just got my 2nd replacement Droid X today, put in sd card and battery and back to the old black screen and green flashing light. I am absolutely livid as I use this phone for my business. I will be taking it in to the store tonight and I wont leave with a Droid X. I expect some sort of reparations.
I take it they never replaced your battery or charger?
Black screen and green light usually goes right along with charging issues. Are you using the cable and wall charger that came with your device? If it is an issue with the charging cable I would have them replace it and the battery.
As for getting your device changed, if you are out of your 30 day no questions asked period, it's not going to happen without you forking out more $$. People usually get mad when I write this, but it's the truth.

Why my iPod Shuffle 3rd won't charge until full (green light on)?

I have new iPod Shuffle 3rd gen, My problem is my iPod won't full charge, I was tried to connect my iPod into my MacBook Pro more than 12 hours and I hope the green light (full charge) will be on. but the result still the same.
I tried to hear via voice over and said that battery only 75%
Any body have the some problem? and how to fix it?

maybe you can control the room temperature.... i try to charge iPod shuffle beside the mini fan, so heat from shuffle can blown away... or maybe, you can charge the iPod in Air Conditioned room....
i think this device have a mechanism to cut off the charging process if device temperature too hot. such a safety system so this ipod won't burn out when overcharging.
i hope it can help you...
and trust me IT WORKS....

Logic pro 9 additional content won't install and iMac 27" late 2012 won't start in Safe Mode

Hi,
I have bought Logic Pro 9 and have encountered problems installing the Additional Content pack. I am using late 2012 iMac 27" (with fusion 3TB drive) and OS X Mavericks (10.9.1).
For some reason the Additional Content pack does not install when downloaded from Logic Pro menu and it does not install either when using the .dmg file. I noticed that many users are facing the same problem, but they have resolved the issue installing the Additional Content in Safe Mode. However, my iMac does not boot in Safe Mode (other users are encountering this annoying problem and it remains unresolved by Apple, see https://discussions.apple.com/thread/5485131?start=0&tstart=0).
This is extremely frustating, because I am using my iMac for my work and therefore it is impossible to backup my data reinstall the OS X. Additionally, I am using the computer for my music projects and I am completely stuck, because I cannot use insrument patches that I need.
Does anyone have solution for this?

Install on my Core2Duo 17" MacBook Pro went flawlessly, but install on my 8 Core Mac Pro suffered this problem. Many thanks for the solution Don, it worked for me ;-)
I am trying hard to supress an ironic chuckle though, reading other posts in this thread .... suggesting that people should call Apple Tech Support and expressing incredulity that people weren't doing this as their first option.
Well I can say say that after several calls to Apple Tech Support, amounting to several hours on the phone, and well over an hour on the phone with them today, I was informed that this problem is a known bug, and that Apple are working on a solution. They couldn't tell me what the bug is, what machines are affected, or what else might trigger it, or when a bug release might be due.
Their troubleshooting steps basically involved various reboots, repairing disc permissions, reseting the user home directory via terminal, booting up in recovery mode (but not safe mode as per this solution) trashing various preferences files, and, as a final step, uninstalling and reinstalling from scratch.
Only when all that failed was I told that there is a known bug that Apple are working on.
I came here to see what the community was saying, as the Tech Support guy did say there was likely to be some info on the forums. Lo and behold, a solution is posted and it works.
Why are Apple's Tech Support (in the UK at least) not aware of this?
Oh well, at least I'm up and running on my Mac Pro now.
Thanks again Don,
Cheers,
Nigel

IMac dead, grey screen, won't start from disks

I'm sure this is going to go over familiar territory.   We have a housefull of Macs and have had for a long time, and I'm fairly used to hunting down issues. This particular one is a problem I've fortunately not seen before. I suspect a serious hardware problem, but only got a look at it once it was fairly advanced.
My teen son was using this computer, a 21" iMac, I think from 2007 (it was a hand me down from his Mac-savvy Grandma).   He says that it was freezing on him for the last week or two, and he'd have to restart. Then a couple of days ago when he restarted he got a folder icon with a ?, so he took the install discs and reinstalled the OS, which was 10.4.   Yes, at this point he'd already goofed, because he'd gone over his data, and though he had an external HD, he had not used it with Time Machine for several months. I don't know what he was thinking, but he's 16...he probably was not.
This was where I finally came in. Yes, get old Dad involved once an issue has reached the crisis stage. :-\
At that point his desktop showed a fresh install of 10.4, which we wanted to update at least, and possibly retrieve his last Time Machine, but I figured there was likely an underlying problem.   Disk utility showed that the disk needed repairing, but I figured that needed to be done from an install disk, and for good measure, I should probably run the Hardware Test as well.
Now things got complicated, because I have been unable to get the computer to start from any install disk I've tried. We have two sets of original install disks from this generation of iMacs (two similar computers), and complete install discs for 10.5 and 10.6, as well as Disk Doctor.   The computer refuses to start up from any of them, with either 'C' or 'D' held down, nor will it start up in Safe Mode. And now the fresh install of 10.4 has disappeared as well.
All that occurs on restart, after the 'bong' is a grey screen. If a disk is in the optical drive, there is a brief sound of it spinning up, then silence for a good while, maybe 2 mins, then the disk is spit out. Nothing more. I have zapped the PRAM or whatever it's called these days, with no change.
We did have an external DVD drive somewhere and I'd like to try that, in case there's a problem with the optical drive itself, but I am thinking this computer may have both disk and hardware issues.
Any advice welcome...thanks in advance!

Hi, sounds like the Hard Drive is dying, & that can prevent booting up.
Hold alt key on bootup, what shows as boot choices?
Have you unplugged all peripherals, cords, & AC power, let sit 30 minutes & try just with AC connected?
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...

Mouse troubles with iMac Summer 2000 DV with OS 9.1

Hello all,
I have recently inherited an iMac as above, but am having trouble with it. I don't have a keyboard for it, but i do have an old school apple mouse for it. The mac starts fine, but when you are on the desktop you can move the mouse around, but you cant click on anything. Aside from this everything seems fine. I have been using macs for many years now, but am stuck as to what the problem could be. My only thought is that it might need a keyboard just to function.
if anyone could shed some light that would be amazing.
many cheers

Hi, mmemarc -
Welcome to Apple's Discussions.
Unlike earlier Macs (perhaps ADB-based ones, certainly the very early ones with phone-connector type keyboard cabling) which would not fully boot, if at all, if a mouse and keyboard were not present, the USB-based Macs will boot satisfactorily whether or not a keyboard and/or mouse is connected. This is in line with the hot-swap nature of USB.
Old mouses (old hardware of any kind) can be suspect. Unfortunately, in order to test that you will need to get a functional keyboard for the Mac in order to use startup commands.
You need not use an Apple-labelled keyboard; there are many 3rd-party keyboards which work well with Macs, even with OS 9. One company in particular, Macally, offers keyboards for Macs which are also compatible with Mac startup commands - and they are less expensive than Apple keyboards.

IMac update crashes computer won't start anyone else having this issue?

The latest update keeps causing my iMac to restart over and over the first word that comes up when it begins to restart is "panic" I'm guessing that's not a good sign!
I'm disgusted that there is no 24hour AppleCare service available, what am I supposed to do until business hours tomorrow. Not good enough Apple!

If you can't boot in the usual way, try a safe boot. During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. If you have more than one user account, you must be logged in as an administrator to carry out these instructions. Safe mode is slower than normal, and some things won’t work at all. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the startup volume is on a software RAID, you can’t boot in safe mode. If you're able to boot, launch the Console application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. ☞ Open LaunchPad. Click Utilities, then Console in the icon grid. Select the most recent panic report (with a name that begins with "Kernel" and ends in ".panic") under the heading System Diagnostic Reports on the left. If you don't see that heading, select
View ▹ Show Log List
from the menu bar. Post the entire contents of the report — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post any other kind of diagnostic report, such as a hang report.
