Logic board replaced, SN is now "SystemSerialNumb"

Ever since my first logic board replacement System Profiler lists my "Serial Number:" as "SystemSerialNumb"
Anyone know how to fix this? I made a point to tell the service tech about the issue before my 2nd logic board replacement and asked them to make sure it was "registered" properly this time - but no luck this time either.
13" Macbook | 2 GHz | 1 GB RAM | Mac OS X (10.4.7)

I just got an answer to this issue from AppleCare....
Your serial number is tied directly to (and encoded on) your main logic board from the factory. When you receive a replacement logic board, the replacement does not have a serial number encoded on it (to prevent from having your serial number change and thus having a mismatch between the one stored in ROM on the board and the one attached to the label in the battery bay).
So, long story short - if your logic board gets replaced you will not ever get the old (or a new) serial number to display in the system profiler. I guess this is minor annoyance that we have to live with....okay, I'm over it. I'm just glad to know I can stop trying.

I just had my logic board replaced. i am now having trouble with using the interent even with a strong connection. all other devices are having no problem with the internet. please help

Test while started in Recovery : if the problem persists, then it likely is a hardware issue.
Resetting the System Management Controller (SMC) probably won't change anything, but you can readily do it before contacting the repairers.

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.

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:

Replaced logic board...iTunes now says "not authorized to play music"

I had the logic board replaced in my Mac Book Pro, restored my 4GB iPod Mini, downloaded iTunes 7.4, and now, when I try to sync with the iPod, I get a message that says that I am not authorized to play any of the music on this computer. I've authorized the computer via Store-->Authorize Computer and have only 2 of 5 computers authorized. I'm wondering if iTunes is seeing my MacBook Pro as a new copmputer because it has a new logic board. I did not lose any hard disk content, so I'm wondering what else the problem could be. Anyone have any ideas on how to approach this? Any help is greatly appreciated.
Thanks,
Ethan

I'm wondering if iTunes is seeing my MacBook Pro as a new copmputer because it has a new logic board.
Almost certainly. Check out the customer service article.

Logic Board Replaced, Now SuperDrive Wont Work

I recently had my logic board (motherboard) replaced by Apple. Now the optical drive (SuperDrive) won't work. Specifically, when I try to insert a disc, the SuperDrive does not sense the disc and it will no will not load the disc. Any suggestions to this problem?

Do you hear any sounds from the optical drive at all? If not, the technician may have simply neglected to plug it back in, or perhaps the cable was not well seated and has popped out.
In any event, contact Apple. The logic board replacement has its own warranty, and if the drive worked prior to the replacement and does not now, Apple will fix whatever is wrong under warranty.
Good luck!

Replaced logic board on MacBook Pro; now I must reauthorize!

I've just synched my iPhone with my MacBook Pro which came back today after having its logic board replaced under the nVidia issue recall program. But I am not that comfortable with the idea that I've now used up 2 of my 5 computers for apps/songs etc.
What can I do? I imagine that I need to inform Apple to de-authorize my previous logic board. But how?

If you weren't able to de-authorize your MBP before sending it in for the logic board to be replaced, I don't believe you can reset or de authorize all currently authorized computers until you reach or authorize 5 computers. You can then do a complete reset or de-authorize all authorized computers followed by re-authorizing the computer you are currently using.

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.

Logic Board replaced now no Serial...: Apple Support Communities

Logic board replaced, now network settings won't save

Got the black screen, Apple replaced the logic board on my MBP for free (yay, Apple!), but now it won't remember my network settings. I have to run network diagnostics, type in my pswd, etc., every time I wake from sleep.
When I first got it back from Apple, it couldn't find the network at all, and Apple gave me free tech support (again, yay, Apple!) because I successfully argued that the logic board replacement had caused the problem. I didn't realize in that support session that setting up a new network, while it would be saved in the system, would not automatically stay "on" -- otherwise I would've dealt with that then.
Running: 10.5.8 on 2.2 ghz late 2007 MBP. Cable modem and Airport Extreme. Others in house have no problems with wireless connection. The only thing that's changed is my logic board.
I read through several discussions, which talked about editing system files and such that I'm extremely uncomfortable doing, and there doesn't seem to be a definite solution for this problem stemming from logic board replacement.
Thanks for any help...

Hi Kren,
It sounds like just a setting: Open System Preferences > Network > click on Advanced > click on Remember networks this computer has joined > you may wish to uncheck all the boxes for Require administrator password > click OK (I don't remember if you have to click Apply on the next screen, but if it's highlighted, you need to; if not, close Network and you should be good to go).

Fans Now Kick on to "Cat 5 Hurricane" Speed After Logic Board Replacement

I have been around and around with this issue with tech support/product specialists and "Geniuses" at Apple Stores, and all I seem to be getting are shoulder shrugs from one and all.
I recently had to have my logic board replaced --and since doing this, the fans come on for what I feel are "innocuous" reasons --say just watching a YouTube vid or opening a "heavy" PDF, Safari being the ONLY app open.
Did not do this before the repair --I could certainly care less since I of course want my MBP to stay at its coolest, but the amount of noise seems to feel like trying to kill a mosquito with a cannonball.
Anyone familiar with this issue?
Thanks in advance

All those steps already have pretty much been taken, S.U. --since the logic board replacement was done at an Apple Store, I immediately took it back to the same Apple Store and the "Genius" ran through all those things --I'm still having to monitor what it's doing when they kick in, but the only thing unusual I see is when Safari goes right to the top of the Activity Monitor after clicking on the CPU column when I'm on one of these "innocuous" sites.
Since then, I've gone to yet another Apple Store, left my computer NEEDLESSLY there overnight (they didn't realize they didn't have the parts till the next day --not exactly sure WHICH parts --but the "Genius" thought it'd be a good idea to replace the fans --not sure how that makes any sense --I mean, the FANS work FINE --they just come on all the time!!) --took it back yet again and the "genius" (note quotes) decided it'd be a good idea that installing the newest version of Flash Player would solve the issue --what a surprise that it didn't!.
So here I still am --in a place where just going to the Corner Bakery website sounds like a tornado is about to hit.
Then today, I had a supposed product specialist @Tech Support tell me "so what's the problem? The fans mean they're keeping your computer cool" --I s**t you not!!
CMCSK, I couldn't agree with you more and have, in fact, had to take this to Apple Consumer Relations --who basically told me it's all up to the techs/"geniuses" to fix but they'd add a notation on the case to expedite should it require another repair (cause having my MBP [only computer] in the shop for a week to replace said logic board cost me dearly!!).
BFD.
Of course, doesn't help matters that the timing of this is right at a time when you can't even get IN to the "Genius" Bar because of the whole post-holiday rush.
My AppleCare runs out in like 100 days --hope they can resolve this before then --don't laugh.
This is really screwed.

Has the NVidia GeForce 8600M GT logic board replacement program been extended by a year?

I have heard that the logic board replacement program for MacBooks Pro with the failed NVidia 8600M GT chip has been extended from 3 to 4 years after the date of original purchase. However, a local AASP had no knowledge of such an extension. Is this true? I have a MacBook Pro 17" 2.6GHz that was purchased in 2008.

when you took it in, it had been more than four years since your 2007 machine was originally sold, that's why you got the response you did.
Actually it was within the time frame, it felt like it was just last month, when it was like several months ago.
Just dragged the 15" recently out to see to use it for testing *cough* and low and behold it's worthless now.
The problem I have is I told them at the Genius Bar the video was going, but couldn't prove it as it was very rare it occured.
But they ran their little tests and gave me a load of crap, now it's dead. $2500 down the toilet.
I know what did it, Lion. Lion was the cause, it ran like a fine machine under Snow, fscking Lion, I'm glad I didn't put that POS on my new 17"

Macbook Pro Mid-2012 Logic Board replacement, Apple Dragging feet?

First some background:
I have a macbook pro 13" Mid-2012 non retina covered under applecare until Jan. 2016. Starting in late march, i had noticed some performance issues but never took it in as the issue would subside within a day or two. Going into the final two week of my college semester, the macbook started freezing and tacking almost 5 minutes to boot. Suddenly it would take 5 tries just to get it to boot. due to this, i had been unable to get the time machine backup to work as it would freeze for 12 hours on average.
So thenI took my macbook pro into the local authorized apple service center (on April 29th) as i suddenly got 'open error 5: input output error' errors and my mbp wouldnt boot at all. When i spoke to the servicer, he and I agreed that at minimum the hard drive was failing. The servicer made a time machine backup of the data on the hdd and got the backup on my external drive. He asked to keep the external drive as it has a partition that is a USB install disk of the latest Mavericks. Soon after he got the data backed up, the hard drive showed signs of failure to happen soon. So we agreedto have him replace the hdd. He hoped to have my macbook to me by May 5th. Well on May 5th, i got a call from him that with the replacement hard drive, the computer still had similar issues and was able to track it down to logic board issues. We agreed that since he had the macbook pro already and since it was applecare covered, we should go ahead and replace the logic board. Anyways, he ordered a new logic board from apple last monday (May 5th, 2014). I called on Thursday for an update and the servicer was frustrated with Apple that something is going on and he hasnt received the part as Apple usually gets him these parts within 1-2 days of request.He said he will call me once Apple gets him the part as he will get on the repair once the part comes in. He hasnt called me back yet.
This is rather frustrating for me as my macbook had all my college files on it and this problem happened right before college finals (i technically lost about 2 months worth of web design files and class files) where much of what needed for finals was on that computer. if he could have gotten it back by the 7th as he'd hoped, i would have been fine. Instead, i was forced to go back to my PC laptop and try recreating some of the files that were made by mac only applications into something similar on windows. i was unable to recover the web design files as they were on the macbook and i couldnt remember right off which folder it was in. So i had to scrape together things to be able to submit for my finals so i wouldnt totally bomb the course. My web design instructor understood how frustrated I got from losing all that work and having to settle for a final design that just met the requirments rather than the one on the mac that was well past it.
He is not sure whats going on as the last time he ordered a logic board for the same model, he had it by the end of business the next day. He is apoligizing for everything . I am not frustrated with him, rather I am frustrated with Apple as they had recommended me to take it in ASAP, yet they are seemingly dragging thier feet on getting him the parts.
On top of this, I am helping a neighbor modernize her business website, and am doing a project with the state unemployement office to help them redo thier videos. Both of these are things i would always use my mac for as it is like 5x faster than my pc on this stuff. It's more than just an inconvience now. I need my mac badly as the PC is just not fast enough to do what i need in the itme i am given (which i why i switched to mac as my primary computer).
Is this common for Apple when it comes to logic board replacements for macbook pros or what?
Has anyone else had this issue?

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

Grey restart and program crashes after logic board replacement?

Apologies for if a thread already exists for this, I had a look around and nothing seems to quite fit the problems I'm experiencing-
I recently got the logic board replaced on a 13-inch macbook pro, osx lion, 10.7.5. I got this done because of the failure of one of the usb ports and the centre row of typing keys.
however (although the keys and usb now work), after the replacement, I have started to experience problems that weren't present before. These include:
programs spontaneously crashing, examples being safari, itunes, and photoshop
the computer spontaneously going into the grey textured screen and restarting all programs, but seemingly not initiating a full shut-down and restart
itunes has deauthorised me and claims that there are already 5 computers authorised to the account. No new computers have been authorised during the repair time and attempts to deauthorise and reauthorise fail, this was not present before the repairs.
video playback on youtube and similar sites can sporadically cut out completely, either freezing or causing the entire video 'screen' to white out or vanish
playback of other moving graphics such as gifs often is jerky or replaced with transparent or white frames
I've updated all my software to the latest versions just in case it was simply that I wasn't up to date with something, but to no avail. Is this a common error with a solution, or am I going to have to get the logic board replaced again? I'm still within my three-year warranty, but I don't appreciate the concept that I brought in my machine to be fixed, and it came back even more broken.
(safari crashed during writing this, here is the crash report in case that helps)

There's a 90-day warranty on the repair.

Prompted to sign in to trial version of CS6 after logic board replaced

Hello. I purchased CS6 10 months ago and just had the logic board replaced on my iMac. Now, when I open Photoshop on that computer, I get a dialogue box "Sign in Required to use your trial version of Creative Suite 6 Design Standard". I did that, but I don't see a way to enter and validate my product installation code so that Adobe recognizes this as a legitamately purchased version. Any help is appreciated. Thank you.

Since sending the first message, I closed and reopened Photoshop and was prompted to either continue with the trial version or enter a valid license key. I did the latter, so hopefully I'm back in business.

Logic board replacement - do I do it or not?

Hi,
The Logic Board of my iBook G4 14" 1.2 ghz recently died and is going to cost me almost £600 to make right!!!
No I didn't buy Applecare. Call me stupid but I expected Apple machines to be a cut above bog-standard PC machines and assumed it'd last me a while.
If I'd have known these issues before I made my purchase then I'd never have bought the machine - it's 2 years old for god's sake.
I digress.................
I've seen the posts on this board - multiple board replacements seem to be the norm, although by the looks of things the older ibooks seem to suffer the worst from this.
My question is should I expect another board failiure? The service centre is offering me a 3 month warranty on the replacement parts. If my ibook goes down after that with the same problem then I'd be seriously annoyed that I just didn't buy a new MacBook instead. I see I could get hold of their lowest-spec machine for a few hundred pounds more.
What do you guys think?
iBook Mac OS X (10.4.7) iBook G4 1.2ghz 14"

I've seen the posts on this board - multiple board replacements seem to be the norm, although by the looks of things the older ibooks seem to suffer the worst from this.
You'll have to keep in mind that this is a technical support forum specifically for people who are having problems. The topics here do NOT reflect the experience of the vast majority of iBook owners. Apple regularly sold 250,00 iBooks each quarter, so if "multiple board replacements" were the norm, there would be thousands upon thousands of posts here about an issue like that.
Apple did recognize a manufacturing defect in the G3 Dual USB iBooks and created a logic board replacement program for those that failed due to that specific defect. But, it was only for those that did fail and not all of them failed.
Without knowing more about your need and use for your iBook, it will be difficult for us to determine the risk you face by paying for a replacement. There is currently a refurbished iBook 12" 1.33GHz /512DDR /40GB /Combo for £524.25 right now at the UK's "Special Deals" Web site. This computer would have the full Apple warranty and could take an AppleCare Protection Plan as well.
