IMac G5 serial number missing after main logic board replacement!?

After replacing the main logic board on a 15-days old brand new iMac G5 2 GHz 20-inch TFT, the computer serial number no longer shows on" Apple ()/About this Mac" or on "System Profiler/Hardware Overview/Serial number".
As far as I know that is normal, but my question is: is there a way to show the serial number (old or new) again? Resetting the Firmware perhaps?
Thanks.

I got a new serial number sticker to put on the stand base. It also inckuded the new MAC Address for network use.
I would call and see if they can send you one.

    But since techs are not themselves given (allowed) too much information, my feeling is that some of them do things in a different way, depending on how they understand it.
    AASPs and Specialists do not alter serial number information in any way whatsoever, including transfer or assignment of serial number to new components. They are not given the proper tools to do it, and thus aren't supposed to hop into NetInfo or a text editor and change language project strings.
    The French serial number assigned erroneously to that fellow's board got there because it was a refurbished board whose original serial number had never been wiped or Apple themselves assigned the wrong number, not because an inattentive service tech did anything wrong.
    Now, if some service tech DID decide to take it upon himself or herself to hack a serial number there, you still need to contact Apple, 'cause that isn't supposed to happen, and you still don't have a proper serial attached to the board.
    Believe me on this one.

  • MacBook Pro Retina showing spinning ball issues even after Main Logic Board Replacement

    HI there!
    I'm a proud owner of Macbook Pro, 15 inch, late 2013 model. It has 2.6 GHz Intel Core i7 processor; 16 GB Ram, 1 TB PCIe based SSD. The software version is OS X 10.9.4. I have AppleCare.
    1. MY mac developed rainbow beach ball issues. Sometimes it'll last for ages. I took several videos of them. I spent hours chatting with online Apple advisors. They did everything they could possibly do: Repair Disk, Repair Disk Permissions, SMC reset, PRAM reset. When nothing worked, I did clean-install the Mac six or seven times. Every time other apps would randomly cause the spinning ball issues. My Mac even restarted all on a sudden because of kernel panic. So at last, I took it to an Apple Store which is a one-mile drive from London. They diagnosed it as a graphics issues and replaced the Main Logic Board and put it to standard testing which revealed no other anomalies.  After the repair, I noticed that dock icons remain present for a dew seconds when I restart or shut down the computer. So this time I took it to a London Apple Retail Store. The Genius at first diagnosed it as a display burn-in issues and sent it to be replaced with a new one. However, next day the technician who actually worked on the computer, phoned me saying that they could not reproduce any issues and did not replace the display either. I went to take my Mac back and discovered that the dock icons stuff still persist when restarting or shutting down the Mac. When I drew their attention, they told me that it was a software issue that Apple is aware of. Apple might resolve the issues in the future updates. Well, after getting back to my hotel room, I clean-installed my OS  from USB and the dock icon issues were gone. Same version of software, but different behavior.
    2. But that's not the reason I'm here. My Mac has again begun to show the rainbow beach ball one day after the repair, when I try to connect to my Airport Time Capsule through Finder in order to selectively transfer files to my Mac. This time the spinning ball would last for a very short time. But if I want, I can regularly reproduce them. I've also noticed this when installing MS Office for Mac 2011 edition. I'm sure I'll get the nasty ball as I use the Mac more and more.
    3. I've got some questions: Can it be that during the MLB replacement, some other connectors got harmed? Or the issues are not specific to graphics only? Why didn't Apple find any anomalies during testing? I'll go to Apple Retail Store again, when I get the chance to. Once there, can I ask them for a full replacement of the Mac? Shall they take my request otherwise? I really don't feel comfortable using a shouldered computer which is going to go through many parts replacements.
    4. I sincerely need your feedback. Please help me guys out there.

    Applecare was no help at all. I called and did the complaint. They confirmed that it is registered to me and everything but essetially told me that they cant give me answers as to what is taking so long. They knew a repair was in progress but wanted to set me up with an appointment at an apple store? (the nearest Apple retail store is Billings which is 240 miles away, or about 4 hours). i tell them its at the repair place and they go on to tell me they can send me a box to mail it in and have it reapir by them.. They are trying to shift the blame to the AASP and his rep. But he said he has been trying with very few answers from Apple as well

  • What happens after a logic board replacement?

    After a logic board replacement will my hard drive be erased? If so, can I simply restore my entire system from backup using Time Machine? Thank you.

    Your hard drive won't automatically be erased, but some commercial applications may refuse to work, and a very small number of preferences won't be carried over.

  • Serial Number Missing after Logic Board Replacement

    I have a xeon xserve (2007) here that had its logic board replaced under warranty. I am now trying a remote install of a new OS (10.5). While trying the first 8 of the server's original serial number as a temp password (in Server Assistant and ssh), I realized that the serial must have changed in the logic board swap. Of course, the plastic tab in the back still has the old serial and MAC addresses on it, but the guys at the repair place (tekserve) at least stuck one sticker with the new MAC address onto the back.
    Now, I booted into the old OS and found that the system serial number is simply missing form System Profiler (Both GUI and CLI).
    Is there a way to set a new serial? This is making the system virtually useless as a headless install.

    The main board in my MacBook Pro c2d was just replaced with a board whose serial number was "System Serial#". I thought that might be the reason that Time Machine doesn't recognise my backups. I changed the serial to my original with the bootable "Blank Board Serializer , v.3T106, part number 693-6430" from
    http://spftp.info.apple.com/DiscImages/diagnostics/Apple_Service_Diagnostic/_ssps693-6430-01.dmg
    Time Machine still wants to do a full backup. It has many reasons to not do what it's told.

  • Main Logic Board Replaced

    Sent my MBP back for the 5th time for various reasons. This time they replaced the Logic board and it fixed my whine. I don't hear it at all. But they didn't fix my distorted speaker. Balancing from left and right while playing a low tone sound you can notice it still. I guess I will just try to ignore it and let it be. Anyone else sent their's and had the speaker issue fixed?

    Hi, John. Yes, that's normal. I'm not sure why, but it is. Possibly it's so that if you call AppleCare for tech support or problem diagnosis over the phone, it will be obvious to the tech support rep that you no longer have your original LB. If you ever need it, you should still have your Powerbook's original serial number on your sales receipt or original box, and perhaps on the PB's original serial number label — though I've heard of Apple removing those too.
    A Powerbook's serial number, as it comes from the factory, is identical with the serial number of its logic board. If the logic board is changed out, the PB's serial number doesn't agree with the serial number of the new LB. If either number still appeared in System Profiler, it could be misleading.

  • IMac...hard drive, optical drive, logic board replaced...

    Hi everyone...Just wanted to post for general info, sympathizers, etc...I had multiple problems with my optical drive (watching/playing/burning dvds cds, etc) and spent an obscene amount of time with tech for the better part of two weeks. Something another user properly coined "the spinning color wheel of death" would also show its ugly face more than usual for long periods of time. Optical drive replaced - same problem. Archive and Install, failed. Erase and install, failed. I spoke with many product specialists and more than a couple were whiny babies who would rather argue with me than help me solve the problem. Then I spoke to this one guy who cut through all the bs and told me he would send someone to replace the hard drive, optical drive and logic board (just in case). That done, the install disk failed again(disk is unscratched). Now they're sending me a new install disk set. No computer for 3 weeks now. As disgusted as I am, Apple support was redeemed by that one product specialist. Anyways, has anyone had this many problems? How much money is Apple willing to spend (replacement parts, onsite repair, labor, phone time) before they replace a computer? It seems that good support is all luck of the draw...tbc.

    It seems to me that you pretty much have a new computer, all your components have been replaced
    That being said, I have had all the same things, with the exception of the hard drive, thank goodness, replaced under Apple Care without any complaining. I also have a new PSU. The trick is to get the original tech who first responds to your call to kick you up to a specialist, who usually knows more than I do and is willing to work with me. I find that once I reach this level, or one above, they understand the problem and realize that messing around with archive and installs is not the answer.
    By the way, what you call the spinning color wheel of death is affectionately know as SBOD which is the spinning beach ball of death, or SPOD, the spinning pizza of death.
    Hope this makes you feel better,

  • After logic board replaced- SystemSerialNumb listed as serial number

    I just noticed this.. I had my logic board replaced a few months ago. Now when I go to About This Mac, it lists my serial number as: SystemSerialNumb
    The number is no longer there. I read about someone else who this happened to. Is there anyway to get the serial number back? I have it printed on my AppleCare.
    The problem is now, if I can't prove this is my system, the one stated in Apple Care, how do I resolve that isse? Will I be able to ever get Apple Care for this computer?
    Any help will be appreciated.
    Bryan

    Hello,
    I have a little trick for you below. But, first I'll explain how this feature works and why it doesn't.
    The serial number you were seeing in the System Profiler is written into a chip on the logic board.
    But, when they refurbish a logic board, they clear out this serial number. Since they have no way of knowing which system it's going to be installed in next, they do not re-program another number into the logic board.
    So, when you get your refurbished logic-board installed, that location that contains the serial number is cleared.
    Apple will often reprogram the number into the logic board on complete systems that they refurbish. But, it is not common for them to do it on the individual logic-boards.
    Unfortunately, the only way to get it to display in system profiler again, is to re-program that serial number back into the logic board. And, Apple is the only one with that tool.
    But, you can continue to use the serial number that is printed on the foot of your computer for all warranty related items. That number is still your "official" serial number. So, the number you use has not changed. It is just not visible in your System Profiler.
    Now, there is a little trick to make your serial number display in the "About this Mac" window.
    You can read about that here:

    I hope this helps.

  • MBP 15-inch 'Logic Board Replacement'

    I just got my MacBook Pro back from the repair center (sitting at the Genius Bar right now). The machine was sent in for heat/whine, keyboard & battery replacements, and a buzzing right speaker. The Genius I talked to initially recommended that they replace the main logic board, keyboard, battery, and right speaker assembly. The repair techs at the Houston repair center ended up replacing a lot of parts, but I suspect that they didn't actually replace the main logic board. Here is a list of the parts used to service my MacBook Pro:
    593-0290 CBL,TEMP SNSR,RT FINSTACK,M1
    593-0233 CBL,TEMPT SNSR,HEATPIPE,M1
    616-0260 BAT,LITHION,60WHR,PLYMR,SMPLO/ATL,MBPR15
    609-0170 SPKR ASSY,PURCH,M1
    630-7249 PCBA,LIO/AUDIO (M1) MBPRO 15"
    632-0366 FLEX ASSY,LIO/AUDIO,M1
    658-0290 ASSY,KYBD,M1
    I'm still at the store so I haven't yet tested whether all these repairs actually fixed my problems; keyboard works great though! At this point I am just wondering whether the logic board was replaced or not. Does anybody have the part number/description for the main logic board on a 15-inch MacBook Pro with 256mb of VRAM?

    I've been home for about five minutes now, and in this quiet environment I've determined that neither my whine problem nor the right speaker distortion were fixed. I still get the whine, which goes away when I run PhotoBooth, put a moderate load on the system, or disable one of the cores. The right speaker still distorts, possibly worse than before.
    Not sure yet whether the machine is running any cooler, though I suspect the new battery may cool things off by a few degrees. On the plus side, after the temp sensor replacements I am at least able to monitor the internal temps (couldn't do this before because readings in Temperature Monitor never updated).
    So I guess I'll have to send my pride and joy back in for repairs again, hopefully for the main logic board replacement I was promised last time. Those b*stards!
    BTW has anyone succeeding in getting a fix for the right speaker distortion? This is certainly off topic and I'm guessing the answer is "No," but it never hurts to ask.

  • I'm giving my MBP 2011 to Apple tomorrow for a logic board replacement. Will they format my hard drive?

    Hi,
    I'll start with the issue. Sometimes randomly my laptop goes to sleep while im using it. It is impossible to wake up from this sleep and forces me to force power off the device. Apple did some tests and concluded I need to replace the logic board.
    I have a few questions.
    I understand they use refurbished logic boards, is it possibly I end up with a worse logic board.
    The hard drive does not need to be formated, will they format it? I have backups but I understand time machine can become troublesome after a logic board replacement. I have a very specific set up and I would need it just as it is.
    Thanks

    They very likely will, and they may return it with the version of OS X originally installed.
    We are users like you, so we are in no position to tell you about such hardware repairs.
    You should have a full backup available. Time Machine will not recognize the computer as your old one neither to restore or to backup. Time Machine will start a completely new backup. My advice is to make a bootable clone you can easily restore:
    Clone Mavericks, Lion/Mountain Lion using Restore Option of Disk Utility
    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.
         1. Select Disk Utility from the main menu then press the Continue
             button.
         2. Select the destination volume from the left side list.
         3. Click on the Restore tab in the DU main window.
         4. Select the destination volume from the left side list and drag it
             to the Destination entry field.
         5. Select the source volume from the left side list and drag it to
             the Source entry field.
         6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.

  • After Logic Board Replacement No Serial Number!

    My main logic board was replaced last week and I just realized that if I go to Finder -> About this Mac and click on Version to bring up my serial or go to the system profiler all it says is: SystemSerialNumb instead of the actual serial number. Should I be concerned? Is this going to affect the validity of my AppleCare extended warranty?

    My apologies - I should have done a search first.

  • No serial number after logic board replacement, now problem to upgrade to Lion

    Hi, I have a MacPro 3.1
    I replaced the logic board 16 month ago and it came back without a Serial Number.
    It wasn't a problem a the time so I didn' mind.
    Now my mac doesn't want to upgrade over 10.6.2, so not to mac osx lion either.
    Any idea of how I can put the serial number back into my mac pro without sending it back for repair? I need it for work...
    Sorry for my terrible english.

  • Two iMacs - 1 Serial Number, What's Up?

    Hi all,
    It's computer invintory time again here at school, and I've got a rather unique problem. In a lab of about 25 G3 iMacs, two of them share (almost) the same serial number when reported by the Apple System Profiler.
    I don't have the serials handy with me, but I can get them if need be.
    Computer #1 is a 400MHz slot loading Lime iMac, the serial number on the case matches the serial number reported by the Apple System Profiler. ie: 1234567890
    Computer #2 is a 333MHz tray loading iMac, the serial reported by the Apple System Profiler is 1234567-890, and the serial on the case is totally different. (ie: 6231532140)
    The only difference according to the ASP the '-'.
    1234567890
    1234567-890
    The logic board for 400MHz computer has not been switched, but the RAM and hard drive have been upgraded. I'm unsure if the logic board on the 333MHz iMac was switched, but I wouldn't be surprised if it had been.
    I've tried new System Folders, ran ASP off a bootable CD, reset the PRAM and NVRAM, trash the ASP prefs and I've gotten the same result every time.
    Both computers have the most up-to-date firmware, and are running OS 9.2.2.
    Anybody ever heard or seen anything like this?

    Daniel_R....
    I am with Duane as not to trust ASP with the Serial Number issue, however I disagree with it being flashed into the motherboard on CRT models.
    I recall that the iMac (CRT) models contained their SN from within the HD. I ditched my petty 6GB HD too soon to see if either a reformat or a zero all data could erase it, however the SN was lost right away with a new HD months after purchase. The iMac G4 (FP) models was the start of having the SN made into some part on the motherboard. I cannot answer other than my eMac as to what other models have motherboard based SNs but I would guess Jan-2002 Mac models and thereafter.

  • 1st Generation iMac G5 with new main logic board but now no Bluetooth?

    Greetings:
    As an owner of a 1st generation iMac, I can finally report that my iMacG G5 is now working fine since the main logic board has been replaced because of bad capacitors.
    A NEW problem has been created. My internal bluetooth no longer works and is not visible in the hardware profile. I suspect that the Apple repair center may have removed my module or that it was attached to the old main logic board. On PC's running MS Windows (XP), there is a "hardware detect" routine.
    QUESTION: Can anyone tell me if the internal module is visible by taking the cover off? I cannot seem to find a photo of where or how the module is attached. I can see my Airport module. Regardless, the Apple repair center said to simply bring it back in and they would fix the problem. They indicated that it was a simple software fix. After trying many different software techniques, I still believe they somehow forgot that my computer had BT and it went back with my old logic board.
    Thanks in Advance,
    Jeff

    We discovered the problem. After taking my iMac G5 back to the Apple service center, I got to observe the technician remove my G5 cover and bluetooth module.
    The problem was due to the fact that the initial technician apparently did not realize he/she broke off the very small connecting pins on the module when he/she removed it from the original main logic board with the bad capacitors. They simply screwed it on the main logic board. They order a new BT module to replace the broken one.
    FYI: It is very easy to install the BT module on the main logic board as I observed. No soldering, etc.. The location is directly above the power supply but below the airport card. It is about the size of a postage stamp and is in clear view withou removing any parts.
    Thanks to All....Miriam...

  • Is it possible to enter a serial number in the main sequence, instead of in the "Pre UUT"?

    Hello!
    Is it possible to enter a serial number in the main sequence, instead of in the "Pre UUT"?
    I still want the serial number in the Report.
    I also want the serial number as file name of the report.

    You can enter the serial number in the main sequence instead ot the "Pre UUT" but there is no reason to do that.
    if you still like to input serial number in your sequence You will need to make sure that you update the variable in the process model which stores the serial number ie. RunState.Caller.Locals.UUT.SerialNumber
    This is used to generate the report.
    the report can also contain the serial number of the uut if you select "New file for Each UUT" under Configure-Report options and in the "Report File name path"
    The format of the name of the report will be
    [123].txt
    "123" was the serial number which I entered.
    If you are not happy about the name of the file you can replace Locals.ReportFilePath to contain the right name using a statement step in the process mode
    l. If you using the default process model please make sure that you add the statement step after "Determine Report File Path" step in the Process Model.
