Mac 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,

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.

    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.

  • 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.

  • 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.

  • Problems after Replacing the Main Logic Board in E280R

    Hi
    I have just replaced the main logic board and FCal Disk Back plane in one of our E280Rs and now we cannot get any out put to a console (or to RSC card). So cannot get to the OK prompt or any diagonistic output. There are no errors according to the system lights although the RSC card is reporting faulty internal disks. Whether the disks or working or not we still should be be getting at least to the OK prompt.
    The main logic board has the same part number as the one we replaced and we swapped the old SEEPROM chip to the new main Logic board
    Any Suggestions greatfully received
    Thanks
    Rob

    LowLuster is correct.
    If Apple techs are talking about replacing the logic board, the costs of doing so is over half the cost of a newer IMac.
    You maybe better off, if it is financially possible for you, to purchase a new or "newer" used or refurbished iMac.

  • Can't open Aperture after Logic Board replaced

    Have a question regarding obtaining new serial number for the Aperture program as after my mac (version 10.5.8)  had a Logic Board replaced
    Aperture program ( 2.1.4) does not open as require serial number what I do no have anymore (all packaging gone long ago).
    So if I  buy a copy of Aperture 2.1.1, it will give me a new serial number.
    Will I be able to use that serial number to open the program I have (aperture 2.1.4)?
    Or what is the best way to obtain images from the program i can't open anymore?
    Thank you

    "Aperture 3 on your new Mac will be able to convert and to upgrade your current Aperture Library." - How ?
    Do you have an external drive, where you can copy your Aperture Library to?
    Make sure, this drive is formatted Mac OS X extended, before you copy the Aperture Library to it.
    Also set the "Ignore Ownership" on this volume flag. (When you select your external drive in the Finder and use the "Get Info" command, you'll see this flag in the "Sharing and Permissions" brick.
    You can simply drag the Aperture library to the external drive, using the Finder.
    Then connect the drive to your new Mac.
    Now you first need to repair your Aperture library - it is safer:
    Select the Aperture library on the drive in the Finder. Hold down the ⌥⌘-keys and double click the library. Select "Repair Database" and let that run. That may take some time.
    After this you should be able to double click the Library and to open it in Aperture 3 as regular library.
    Without an external drive you need to copy using the Network or to mount your ols Mac in Target Disk mode http://support.apple.com/kb/PH3838?viewlocale=en_US&locale=en_US. Connect it to your new mac with USB or firewire and boot it with the T key held down.
    Then your new mac will see the old one as external drive.
    To extract only images from your saved Masters folder, select the Masters folder you copied in the Finder, then press ⌘F. In the search panel that opens add a search (press +) and set the search to "Kind is image".
    This should show all images in the folder.
    Caution! If the headline is set to "This Mac" and not to the name of the folder, you need to edit the preferences of the Finder. In the "Advanced" tab of the panel set the "When performing a search" to "Search this folder".
    Don't touch any images in the search, if the heading shows "this mac". Then you are risking to move any image file on your mac.
    Regards
    Léonie

  • Please enter your original serial number, or insert your logic XSkey

    I just re-installed Logic Pro on my new Mac, but upon launching, it asks me for serial #.  Apparently, I'm using the "upgrade" serial, so after I put in the number, it says "Please enter your original serial number, or insert your logic XSkey".  I've searched my big Logic 8 box, but all I have are manuals and disks, with no serial #.  I can't find the old dongle either, since I've been using without it on my previous computer.  How do I get past this?

    Thanks for that post Bee Jay,
    Just tried doing this, didn't work, after closing logic and re-opening without the XSKey it brings up the same 2 boxes, first to insert my upgrade serial and then the original serial. I really hope there is going to be an upgrade to fix this problem as otherwise it looks like ill be stuck with XSKey after all.

  • Why has my macbook pro serial number changed after getting it repaired?

    I just noticed that the serial number in the 'about this mac' information has a different serial number to what is on the back of the macbook pro, which is the same serial number on my apple care/phone . I had a lot of issues with my macbook pro it was sent to repair in july 2013 then in august 2013. Why has the serial number changed? I tried using my original serial number to use the online apple care service however it did not recgonice my serial number when I tried the new serial number it regconised it but said I did not have apple care but I do. I don't know what the apple team have done to my macbook as it requires to go in for repair again.

    Was it repaired at Apple or an authorized service provider?
    You need to contact the repair place/store and/or call Apple and make them aware of the problem - sooner rather than later. Make sure you give them the repair/case number so they can find the paperwork for it.
    I had a logic board replaced and the tech also did not do anything - I called Apple and the tech came back to my house to take care of it. It's important because you want to make sure that your Applecare is being associated with the right serial number.
