PM G5 Dual 2.0 Internal Power Button ?

Hello
Does anyone know if the PM G5 Dual 2.0 has an internal Power Button ?
If so, where is it exactly ?
Thanks
Tim

Hi Tim, not a Power Button per se, but a PMU/SMU button...
How to reset the SMU on a Power Mac G5 (Late 2004) or Power Mac G5 (Late 2005) ...

P67A-GD53 internal power button diable?

Does anyone know how to disable the internal power button? It seem i have to open the case every time the computer is off for more than 15 min or so to turn the machine back on. I feel like ive been all throught the bios and cant seem to find it.
Thanks in advance!

Thanks for the help - Turns out, i had the wires correct but plugged the little connector that all those wires go into in the wrong socket. I guess JCOM1 has the same blank spot as JFP1.
Short version - it helps to plug the wires into the correct place.
Thanks again!

PowerMac G5 Dual 2.5GHz Remote Power Button ??

Hi,
I'm moving a G5 to a place where it would be hard to get to the power button. Is there any way to add a remote power button?? Any help would be great thanks.

Hi Ampex351-
Did you by any chance search the forum regarding this subject? I know that this has come up more than once and the most eloquent solution seems to require a small amount of surgery on your Mac in order to install the contacts of a small 12V relay in place of the power button and have that switched from a remote location via the application of 12V.

No Chime, display or illuminated power button QS Dual 1 Ghz

Hi. I have a PM G4 Dual 1 Ghz. It was a great computer until about 2 years ago when it sadly stopped working. I found a broken capacitor on the motherboard (No. 820-1342-B) , so figured it was a bad MB. I replaced the board with a (No. 820-1276-A) board and had no luck. The symptoms-the same as on the new board. I purchased a tested and working board (No. 820-1342-B) and still had no luck. I am beginning to suspect a problem with my processor card or my power supply but I don't want to put any more money into it. I have tried to reset PRAM but the keyboard isn't recieving power. The symptoms: Power light when pressed in, red light on logic board, fans, hd, and optical drive work. No keyboard, display, or chime. Please help- I want to donate this computer and can't bear throwing it away

You never said if you replaced the PRAM battery.
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
For G4's and earlier models, check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject.
There are other tips in there too.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

If it won't turn on then the monitor is dead (power supply?, video circuits?). Not worth repairing.
If you have a new iMac then it has thunderbolt. So exactly what is that monitor you are trying to connect? For TB you can connect a mini-displayport monitor. Probably (not 100% sure with TB) can use dvi or vga too if you have the appropriate adapter.

Fairly simple fix for dv6000 power button, microphone, internal speaker problems

I have a dv6000 notebook computer, S/N CNF6380XM1, P/N EZ829AV.
Over time (I've had the computer for almost 4 years) the power button, internal speakers, and microphone became increasingly flaky and eventually stopped working altogether. Classic signs of a bad connection. I could still turn on the computer by touching the QuickPlay button to the right of the power button.
I used the Maintenance and Service Guide, HP Pavilion dv6000 Notebook PC, Document number 416618-003 (PDF can be found online from HP) to get the removal/replacement procedures for the switch cover (the piece of the case above the keyboard that has the power button, the Quick Play buttons, and the speakers) and the power button board. Remove three silver screws inside the battery compartment, pop loose some snaps along the top edge of the switch cover, and carefully fold the switch cover back over the keyboard. The power button board is pretty obvious other than knowing you need to slide the latch ears on the ZIF connector away from the connector body (towards the flex cable) in order to release the flat flex cable.
The power button board has flat flex cable that connects to the motherboard. In addition to having the power switch, this board is used as a breakout board for the microphone and the internal speakers. I looked at the contacts of the ZIF flat flex connector under a microscope and aha!, just as I suspected, they are gold plated. You might think this is a good thing, and it would be if the mating contacts on the flat flex cable were also gold plated. But alas they are tin plated. Gold + tin + vibration + time = bad connection. For those interested in the technical details of this, do a search for "fretting corrosion".
Since I'm pretty miserly and like to fix stuff, I decided to try simply cleaning the contacts. I cut a strip of carborundum paper (very fine abrasive coated paper) the same width as the flex cable, insert it into the ZIF connector, close the latch, and pull the paper out. I repeated this 3 times, then shot some compressed air into it to remove any gritty dust. I then rubbed the contacts of the flat flex cable with the carborundum paper and wiped them off with a clean static-free cloth.
After reassembly, everything is working again! Since this didn't address the root cause of the problem, it will probably eventually start acting up again, but maybe by that time I'll be ready for a new computer anyway. A proper fix would be to replace the ZIF connector with one that has tin contacts, and to replace the flat flex cable.
This is a design flaw on the power button board. A ZIF connector with tin contacts should have been used. Ironically, I learned about fretting corrosion over 20 years ago from an old HP reliability guru named Ed Aoki when I was an engineer in the HP medical electronics business.
After doing an internet search on "dv6000 power button", I saw that there seem to be quite a few frustrated people out there that are having similar problems with internal speakers and microphone. The troubleshooting flow chart in the service manual does not help to properly identify the problem component (the power button board and flat flex cable). Hopefully this info will be helpful.

No, its too expensive for HP to plate the zif connectors with something that doesn't corrode....rolleyes.
Thanks nice tutorial.

Replacing Power button dual 1G MDD

The front panel power button on my Dual 1Ghz G4 MDD is getting "flaky". I have to push it a bit sideways and to the right for it to work. Any words of wisdom on how to replace the assembly and where to buy it? The local Apple store is only "allowed" to do trades. I bring them the bad assembly and leave it with them, then they will order me a replacement. That could take "a few weeks". When I pointed out the obvious (that I would then have a computer without a power switch) they obviously understood but couldn't do anything about "policy".
Thanks,
Tom

Hi
Instructions for replacing the front panel board can be found here:
http://www.info.apple.com/usen/cip/pdf/g4mdd/g4mdd-fpb.pdf
Unfortunately it's a bit involved as the optical drive carrier and optical drive bezel have to be removed first.
I've never used them before, but the following is one company that seems to have the part for around $50:
http://www.mac-pro.com
I'd double check the problem is with the front panel board and not the button itself in the bezel before you buy anything though. I guess it's possible it's just gunked up and needs a clean.

Dual G4 won't turn on. Power button just blinks

Hi everyone, first off I'd like to say that I know there are a number of similar posts to this but I read many of them and I think mine is a little different.
Earlier today my Dual 1.42 G4 powermac was on and was in the screen saver. I pressed the sleep button on my Apple 23" display and nothing happened. I waited about ten seconds and, needing to leave, pressed it again and left. Well, I returned now and found the computer was off. I pressed the power button on the display and nothing happened. It just blinked. I then pressed the power button the computer and it did the same, just blinked for a second.
I just followed Texas Mac Man's directions from other post by unplugging the power cable and removing the battery. Waited ten mins and tried power it up and nothing happened. Same issue. There are no start up chimes/beeps and the fans do not spin up.
I also found a link that showed how some powermac's power button go bad and that a usb keyboard with a power button can start it up. My display has a power button and it couldn't turn the computer on so this isn't my issue, right?
Some info about the comp: Dual 1.42, OS 10.5, everything stock except a ram stick I added three years ago. Thanks for your help in advance and can't wait to get this old champ running again.

I debated starting yet another "my G4 won't start" thread since my problem is more similar to Tammy in MO's.
My Dual 1 Ghz G4 (Mirrored Door) won't start up when I press the power button. The power button usually does not light up upon touch. The computer does not shut down on me when I am working on it.
The only way to get it to start up again is to unplug the power cord from the back of the computer for a minute or two (not long at all) and then plug it back in again. If I do this, I can run the computer all day without any problems. Once it goes to sleep or shuts down, then I have to unplug it again and start over.
I have done the following:
Replaced the battery.
Reset the PRAM:
http://support.apple.com/kb/HT1379
Reset the PMU:
http://support.apple.com/kb/HT1939?viewlocale=en_US
as well as done the PSU test:
http://discussions.apple.com/thread.jspa?messageID=9301520&#9301520
This last test yielded no voltage results, best I can tell.
Truth be told, I don't think I did the PSU test properly since the ends of my voltage tester are probably a bit too large to properly test the pins.
http://img244.imageshack.us/img244/4280/fw800pinout.png
I even tried to discharge the power from the logic board:
http://discussions.apple.com/message.jspa?messageID=582223#582223
BTW: The red led on the logic board does come on and stay on when the unit is powered up and running.
I was wondering if this has happened to anyone else, and if anyone knew how to solve the problem.
At this point since this machine is relegated to my wife and kids so for me it's more annoying than anything else. Any other suggestions or advice would be appreciated.
Thanks in advance.

Dual G5 won't power on - power led lights on push only

Hi,
My 2Ghz Dual G5 doesn't turn on and I hoped someone could provide advice on repair.
When I push the power button the power led lights (once) but nothing else happens.
I have reset the pmu, replaced the internal battery and swapped RAM with known good.
I don't think my model has internal LEDs on the MB.
Would the power led still light if I have a bad power supply?
Is there any way I can tell if i have a bad motherboard rather than a bad power supply?
Thanks,
Tom

In the G5 manual, in the section on trouble-shooting, it says what one light blinking, two blinking, 3-blinking means.
I'd look it up for you right now but I'm at the libary, using their public computer, since my PowerPC G5 also died, at last, 4sure, last week. I had that light blinking three (3) times.
I've come to conclude it is a bad logic board that many other threads mention. Cost for repairs are very high.
I (seriously), without realizing it, went through some noted classic symptoms of "grief." -- First, there was Denial (i.e. Disbelief); then Anger; Then I tried last gasp measure to make a miracle happen, trying to "be reasonable and negotiate," a fix.
All repair people I contacted told me to buy something new. I "lnegotiated," some extended credit and creative bridge financing. (Um...can you spell: p-a-w-n shop....deliberately going into overdraft protection...whatever I had to do, etc.)
Today, I placed the order for a Mac mini, M239LL/A. ON EVERY SPECIFICATION it is better than my now dead PowerPC duel 2.3 G5 tower and cost one-third the price. Plus it has Bluetooth and Wi-fi.
The Black Friday Sales are soon approaching so this may be the best time to make the transition. It would have cost as much to ship and repair my G5 tower and not only do you get the latest version of iLife, Snow Leopard, but rebate deals that you can get when buying a new computer offered iWorks at half-price, discounts on other Apple software, and third-party software. I got a full $80.00 rebate on an HP F4480 all-in-one printer (that only cost $80.00...plus you get that free subscription to a Mac magazine and back on the cutting edge of computers instead of looking at other's ride the surf.
Ten days ago I was devestated. Today I am as excited and pleased as I was five years ago when I got the G5 tower.
EVERYBODY I talked to, at the library computer lab, friends, all nodded their heads sagely and said: "Yea, five years...that's about it for a computer."
It just took me ten days to 'go through the transition. It was strange that something so valuable suddenly was worth nothing; i.e. not even worth repairing.
I had 4.5GB of RAM. Never needed more. Now I'll have 4GBs of 150% faster ram, 14% faster CPU, the new apple age mainstream Intel chip, etc.
I was using two PCI-X slots...that's about the only thing I won't be restoring but their use was not necessary at all and PCI-X slots were almost out of date the day i got them and what I really wanted, a video graphic's card, didn't exist for PCI-X.
So...that was my experience with this unfortunately event -- the death of a good machine.
But I was very pleased to have 4.7 years of trouble free prime time computing and didn't really think about leapfrogging to the future and doing it again.
If my old G5 was still going I'd still be a-okay with it, but stuff was happening with software improvements that were for Intel only and that just, slowly at first, got more significant.
The death of my G5 was like a "wake up call!'

I have frequent instances of my Macbook Pro beeping 3 times and then I have to forcefully shut it down by pressing the power button. What is this all about? Please help. Thank you.

Hmm. The problem still may be the RAM - Apple buys the RAM it puts in its machines from third-party vendors (usually Hynix) so it could be a RAM problem.
There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
Run Rember first... call back with results.
Good luck,
Clinton

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

Mid-2010 15in. MacBook Pro going to black screen requiring reset by holding power button

Hello all,
     I have been searching for a problem solution for quite some time now. I have a mid-2010 15" Macbook Pro (2.4GHz Intel I5; 4 GB mem) updated to version 10.7.5. The computer randomly goes to a black screen, while the program / movie / whatever is still running (I can hear the sound) and then stalls. I then have to hold the power button down until it will reset. I will post the error message at the end of this.
     I have wiped the computer clean and reinstalled everything and that did not help. I am no longer under Apple warrenty and hoping that someone has experienced. Short of me finding an answer I will take it in to Apple. Thanks in advance for any help!

You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the first page of the panic report, and the support page linked above, and bring them with you.
Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Sometimes the replacement part is also defective, so be prepared for that possibility.
If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
*An SSD doesn't need to be zeroed.

Kernel Panic: You need to restart you computer. Hold down the Power button until it turns off, then press the Power button again.

I apologize for writing a book, but I think explaining the full story may possibly get me a correct answer. I hope that someone can give me some insight as to what is the problem with my MacBook Pro. I have a MacBook Pro (15-inch Early 2008), model identifier: MacBookPro4,1 running OSX Lion 10.7.5 with 6 GB memory. My wife first noticed a problem with the display. Every so often it would get fuzzy with jumping lines going across the screen making it vitually unviewable. The final time that incident took place the computer froze which required holding down the power button to restart the computer. The computer started up to the point of the Apple logo and the spinning gear for quite some time until the screen darkened from top to bottom displaying the following message in five different languages: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." I have read other blogs and support communities where people get the message intermittently, but my computer would not go past that point no matter what. Through research and the Apple Store I was told that this is a Kernel Panic. The so called "Apple Genius" at the local Apple Store was unable to get the computer to boot past that point even with his gadget. It would not startup in recovery mode, safe mode or off of a disc. I forget exacty what he told me, but he said it was getting past the first two startup steps, but it would not get past the third step which is to mount the desktop. He guessed that it may be a problem with the hard drive; a loose wire or something or other. I disconnected the hard drive completely and took it out. Everything appered to be connected properly. Then I installed it back correctly, but it did not solve the issue. So I guess I disproved his theory of a loose wire... I purchased ProSoft Data Rescue 3 and connected my MacBook Pro to another Apple computer using a firewire 400 cable. I was able to get everything I needed off of the hard drive. I did some more research and I decided to restart the MacBook Pro in verbose mode (holding down the command button and V button). The computer magically started up!!! I was upset that I wasted my money on the ProSoft Data Rescue 3. I managed to take additional items off of the computer and back it up on to an external hard drive. After some time the computer froze. I repeated the power button process to restart and received the same kernel panic. I managed to get the computer to startup approximately six or seven more times via verbose mode; each time the computer staying on for a shorter amount of time before it would freeze. I managed to run Disk Utitlity. I performed first aid to fix the hard drive and it said that the hard drive appeared to be fine. After first aid I erased the hard drive and booted off of a Lion disc to perform a clean install or an erase and install. Lion installed until the progress bar got the the end where I received a message that there was an error installing Lion, please try again. Each time I attempted to install the software I would receive the same message. Eventually the computer would not boot from the Lion disc. I went back to the Apple Store and the Apple Genius was able to get the computer to boot off of his gadget where Lion istalled completely. I set up the computer as a new computer. He said that he partitioned the hard drive as DOS and then back to Mac OS Extended (Journaled) which would get rid of any errors the drive may have had. He guessed that the problem was the hard drive, but was not exactly sure. When I brought it home I installed all of the software applications I had on it previously. Approximately three days later, which may have been the fifth of sixth time starting up the computer, the display became fuzzy again and the computer froze. The computer did restart once and I was able to retreive a "log" which I have pasted below. After if froze for the second time it restarted once using verbose mode and froze almost immediately. After holding down the power key to shut it down and then restart; I received the same kernel panic after the Apple logo and spinning gear which put me right back to square one. Now the computer will not boot via any method. It freezes at the end of verbose mode which forces you to hold down the power button to shut down. I also read that poorly seated ram may cause this issue, but I removed and installed the ram multiple times. I even purchased new ram from Other World Computing (Mac Sales) 6 GB, but that did not make a difference. I think I may see six possible problems on the verbose screen mode, five errors and one warning; I will type them out here:
1. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
2. SMC: :smcReadKeyAction ERROR: $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
3. SMC: :smcInitHelper ERROR: MMIO regMap ==NULL - fall back to old SMC mode
4. WARNING - ACPI_SMCCtrlLoop: :initCPUCtrlLoop - no sub-config match for MacBookPro4,1 with 8 p-states, using default stepper instead
5. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key MOTP (kSMCKeyNotFound)
6. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key BEMB (kSMCKeyNotFound)
I was hoping that someone could read my log to ascertain wether or not they see a problem that stands out. I was also hoping that someone could tell me if verbose mode provides any information that may be wrong with my computer. I just hope that someone can give me some insight as to what may be wrong with my computer. If it is the hard drive I will easily replace it, but I want to make sure that is the problem first before I waste money on a hard drive or anything else. Please let me know if anyone requires any other information from me.
Thank you!

I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card. I also was well aware that Apple offered a replacement program that ended in December of 2012. I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store. I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no. He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime. When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board. I asked myself, how can a flawed hard drive cause the screen to act funny.
nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses." I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it. I guess I will look into purchasing a new machine when I have the funds. Again...thank you both!

17in CRT Studio Display (Blue & White)-blinking power button

I have an Apple 17in Studio Display (CRT-Blue and White vintage) connected to my Power Mac G5.
Last night, I went home, and turned it on..or rather tried to turn it on but found it stayed black, with the power button blinking green->amber->green->amber etc.
As far as the computer was concerned, the monitor was still there and working (dual monitors...the mac kept the b&w as if it was turned on).
I swapped the monitors to the different video ports and the other monitor worked fine, so it's not the video card or vga->digital adapters.
I unplugged the monitor and replugged it, and it stayed with the blinking light.
Restarting the computer with the monitor attached had the computer still running as if the monitor was working just fine, so it seems to be getting what ever kind of feedback the mac gets to let it know a video card is there.
Anyone have any idea what could be up?

Hi I have an Imac I5 21.5 inch.It was working perfectly.Then i didnt use that for about 2 months. Week ago when i want to start the Imac ,it didnt start.
When press and hold or keep on pressing the power button then i hear the fans are working and i get a continuous beep( but low freqency tone).
But screen does not turn on.Please help me to rectify this problem.Best Regards. By the way I am an electronic technician.So if there are any technical things to be done, Pls let me know.I can do it my self.

Hey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:
