HT1349 I received a new logic board and now my computer has no serial number under 'about this mac', and I need it to submit questions to apple. What do I do?

I can't find the serial number for my mac after getting a new logic board on recall for my macbook pro.

You can open System Profiler and see if it contains your serial number.
Or have the computer near a previous connected Wifi or on a Ethernet cable to your router.
Reboot holding the D key down for like what would appear to be 10 minutes until Hardware Test appears on the screen.
You can run a test if you wish.
There is a pane at the top if selected will give you your new serial number.
You also can use Terminal
You can quickly retrieve any Macs serial number via the command line by using the following command string:
system_profiler |grep "r (system)"
The command results will look something like this:
$ system_profiler |grep "r (system)"
Serial Number (system): C24E1322XXXX
If that fails you can give them your MAC address which is unique to each machine and there are records at Apple with it.
Open Utilities > Terminal. Copy, paste and press enter:
For your computers Ethernet (wired) MAC address: ifconfig en0 | grep ether
For your computers Airport (wireless) MAC address: ifconfig en1 | grep ether

I looked up serial number in About This Mac and Support site says it isn't

I can't find my Apple Care plan or read the bottom of the computer but I looked up the serial number on my iMac under About This Mac. I copied and pasted it into the box to get a call for technical support and I get a message saying it is not the right number. Now what? How can I call them to get support without the number?

A valid Apple product serial number is eleven characters long, does not contain the letters I or O—though the numerals 1 and 0 are valid characters—contains the numeral 0 though 9 in the third position and the numeric string 01 through 52 in the fourth and fifth positions.
On your model, it's found screened beneath a barcode on the underside of your foot, or can be found as you were instructed using About This Mac or using the System Profiler application. If your logic board has been replaced and is not the original unit installed at the time of manufacture, your logic board may not have the serial number embedded in firmware. In that case, it is not available to display using the About This Mac dialog or the System Profile application.
The most reliable source of such information is typically the number screened on, inscribed or affixed by label to your Apple product.

Serial Number in About This Mac and System Profiler says "System Serial#"

I recently had my hard drive and motherboard replaced under warranty.
I wanted to check the expiration of my warranty so I could buy AppleCare before my year is up. I went first to About This Mac, and then to System Profiler - both of them say my Serial Number is "System Serial#" - any ideas on how to get my real serial number displayed?

How strange! I'm not sure if this will show anything different, but you can also try to get the serial number via Terminal. Just open the Terminal application and copy in this command:
ioreg -l | grep IOPlatformSerialNumber

New logic board, and new display, but now completely dead.

Hi guys,
I've got an iBook G3, running 10.3.9.
In December 2006, the logic board failed, so I bought a MacBook, because I didn't have time to be offline waiting weeks for Apple to replace the iBook's logic board.
After much badgering, Apple reluctantly replaced the iBook's logic board under the extended warranty program.
While the iBook was with the Apple repair store, they replaced the display for new as well, even though I didn't ask them to, and even though I wasn't charged for it.
I presume that was because the store discovered that the display was duff enough to be replaced under another extended warranty program.
When I got the "repaired" unit home, with a brand new logic board, and a brand new display, I turned it on, and it seemed to be working fine, so I turned it off, and continued to use my MacBook.
A few weeks ago, the second logic board on my MacBook failed (another long horror story entirely), so I began using the iBook for the first time since it had been "repaired" some six months earlier.
Almost immediately, the iBook began exhibiting a major problem, specifically that I'd be typing away, and suddenly the display would go black.
I could just about see the icons and documents on the screen, but the unit was unusable.
So I pulled restarts, full shutdowns, disk utility, zapped the PRAM, etc, all to no avail.
It seemed to be an intermittent problem.
For example, sometimes, from a cold start, the unit would work for two or three hours until the display went black.
Other times, I'd pull a cold start, and it would go straight to the black display.
By chance, I discovered that if I gave the iBook a shake, the display would come back on.
But then it would go black after a second or two.
And then with another shake, it would come back on for a second or two.
And then it would go black after a second or two.
And then with another shake, it would come back on, sometimes for a couple of hours at a time.
So I figured that it must be a cable which, during the installation of the logic board, and/or the new display, wasn't seated correctly by the technician.
I phoned Apple, and told them about it.
They said that because I had reported the issue beyond 90 days since the logic board had been replaced, it was no longer Apple's problem.
I explained to Apple that I hadn't used the iBook for six months, because I had a MacBook.
After much badgering, Apple has agreed to replace the logic board if it's faulty.
However, Apple has refused to replace the NEW display, even if that's also faulty.
Apple is also insisting that I have to pay all the labor charges.
Meanwhile, I've noticed that the iBook is now incredibly hot.
I mean, the MacBook is infamous for running hot, but this "repaired" iBook makes my MacBook feel like a block of ice by comparison.
I don't remember the iBook running so extremely hot before the "repair."
Which has made me notice that during the last few weeks, I've never heard the iBook's fan come on.
I presume that an iBook has a fan ?
Please confirm.
Therefore, another loose cable ?
Today, the display went black again, as usual.
So I gave the iBook a shake.
But this time, nothing happened.
No display.
No fan.
No hard drive spinning.
Just silent and dead.
What do you reckon, guys ?
Duff logic board ?
And/or duff display ?
And/or duff fan ?
And/or duff cabling by the technician ?
As far as I'm concerned, I don't see why I should have to pay for yet another repair, to correct hardware and/or workmanship which was so bad that after only three weeks of ACTUAL use since the "repair", the unit is now completely dead.
All opinions and advice gratefully received.
With thanks and best wishes,

Hi S,
Many thanks for your helpful and swift response.
I agree with you regarding the likelihood that these problems would have surfaced immediately during normal usage, regardless of how much or little time had passed since the repair.
As advised, I will inform Apple Customer Relations UK about the new developments.
Indeed, when I resubmit the iBook, I'll include a print-out of this discussion.
I agree with you about the fan.
Prior to the failure of the first logic board, I ran that iBook for YEARS, without noticing any heat issue.
Indeed, if there had been such incredible heat, then I'd have searched these discussion boards, and reported it to Apple HQ.
Therefore, the astonishing heat is definitely a new development since the "repair."
Consequently, I take on board your comments about the lack of a working fan since the "repair", which I shall also mention to Apple HQ.
As for running the Apple Hardware Test, the unit is completely dead.
The power cable is green, but the unit is now completely silent and black.
I also note your suggestions regarding the cable which connects the display to the rest of the unit, which I shall also mention to Apple HQ.
No repair sheet was ever given to me by the Apple Repair Centre (ARC).
Indeed, no receipt was ever given to me when I delivered the unit to the ARC, nor was any paperwork ever given to me when I collected the unit from the ARC.
However, Apple HQ can see on their screen that the logic board and display were both replaced for new by the ARC.
What else was and wasn't done by the ARC is a mystery.
I'll phone the ARC and ask for copies of any and all paperwork, so that I can submit it all to Apple HQ, which I note is your recommended option, rather than returning the unit to the ARC.
However, the complicating factor is that with the exception of the logic board, it is my understanding that Apple is denying any liability on any part of the "repaired" unit, including the brand new display.
If I understand Apple HQ correctly, they're now saying that all other hardware and labor costs will be mine.
I'm sure I could buy a WORKING second-hand iBook G3 for the same price as a repair, if not cheaper.
Therefore, perhaps I should return the unit to the ARC, and give them the opportunity to correct their previous workmanship, at their OWN cost.
Because as far as I'm concerned, the ARC had two customers during the repair: Apple and the end-user, as evidenced by the fact that the ARC has invoiced its first customer Apple for workmanship which was clearly not up to Apple's own standards, and the ARC has then delivered the unit to its second customer, the end-user.
In addition, regardless of Apple's 90 day warranty on repaired hardware, UK law includes the Sale of Goods Act 1979, and other relevant legislation: http://www.dti.gov.uk/consumers/fact-sheets/page38311.html
Furthermore, if the ARC is completely unhelpful, I could jump all over them, by writing to Apple HQ, with cc's to the UK editions of MacWorld, MacFormat, and MacUser magazines.
As advised, if the unit goes to Apple HQ, I will suggest that the unit is looked at carefully during disassembly, to see if errors were made during the ARC "repair."
I'm always polite when on the phone to Apple, because I love the company so much.
Indeed, even though during the last twelve months, I've been having very bad luck with the iBook, as well as with a MacBook which has exhibited so many problems that Apple has now agreed to replace old for new, I still love my Mac.
And joy, sweet joy, I've just seen on the TNT courier's tracker website, that my replacement MacBook, built by Apple in Singapore, then flown to Arnhem in Germany, then flown to Northampton UK, then delivered to Heathrow UK, left the Heathrow depot 30 minutes ago, for delivery to the customer.
And the sun is shining.
Thank you again for all your kind and wise advice.
With best wishes,
Michael

Sounds just like what was happening with my Alum MB. I took it in and they replaced my battery. It seems to be ok now. I don't know what it is, but my battery was fine before 10.5.6 and the same timeframe of the firmware updates when they came out.
My battery health was jumping around but was fine before all of this happened. Unfortunately at 381 cycles I don't think you have much chance of getting the battery for free. Perhaps you can complain about the battery saying it was fine until 10.5.6 or whatever. Not sure when your computer was made, but perhaps you are eligible for this program: http://www.apple.com/support/macbook_macbookpro/batteryupdate/

Without the serial number your FCE disc is useless and nobody here can help.
Your only chance, if you have the receipt or can prove your purchase is to contact Apple and hope they may be able to help.

Apple installed a new logic board and now iTunes music is all gone and I cannot log into store or authorize my Mac

I have an early 2011 i7 MacBook Pro running OSX 10.9.4. Earlier this week I had Geniuses at the Apple Store install a new logic board to replace a failed one. My hard drive was not touched. Anyway, when I got home and launched iTunes, I discovered that none of the tens of thousands of legally purchased songs in my iTunes library were listed, even though they actually still exist in my Music folder. Additionally, my attempts to login to the iTunes Store with my valid and correct and accurate and current Apple ID with the correct password, did not work. In fact, no errors were generated. The logins simply erased my input after clicking SIGN IN and then the "Sign In" form came back empty.
As a developer and 28+ year user of the Mac, I was a little stunned to say the least. The Apple Store logic board replacement process should take into account iTunes authentication problems when replacing failed logic boards, but this issue was not discussed at all, in any form during the repair intake process. So, I now have a 'fixed' MacBook Pro that will not acknowledge my thousands of legally purchased songs and will not let me log into the iTunes Store with my valid credentials or authorize or de-authorize my Mac.
Indeed, iTunes Match is also disabled, which means $30 thrown away in paid subscription.
Does anyone know a workaround to this Apple flaw that can correct their mistake and re-enable my Mac for using my thousands of legally purchased songs?
Any feedback would be most appreciated!
Thanks,
Larry

Having your main logic board replaced wouldn't erase music from your hard drive, if it was actually stored on the drive. Your iTunes music resides in your user home folder in a folder called Music.
When you do get a logic board replaced, however, it is a good idea to have the computer first de-authorized from iTunes since you are only permitted to associate your iTunes Store account DRM purchases (movies, tv shows, and older digital-rights-managed music) with up to five computers. See Deauthorize your computer using iTunes.
When a new logic board is installed, you'll need to reauthorize the Mac again. It's not the end of the world, however, if this step wasn't initially taken. See Authorize your computer using iTunes.
...As for not seeing your music when you launch iTunes—try point iTunes to the correct location of your iTunes folder. To do this, quit iTunes. Press the option key and click the iTunes icon in the dock. It will then ask you to navigate to the location of your iTunes music (again usually located in the Music folder in your home folder).

New logic board and network connection problems

My late 2007 MBP just had a new logic board installed. I have home and work wireless networks that are configured to connect automatically. This always worked flawlessly in the past. My MBP would find the network, connect and all was well. Since I've had the new logic board I'm having issues. The wireless network will be detected but an IP address is not assigned so I can't get on the network or internet. Both my home and work networks were set to assign a specific IP address to my computer. The MAC address detected by the router is correct, at least according to System Preferences.
The only way I can connect is to disable the firewall (Allow all incoming connections). When I do this I connect immediately to the network and everything works as normal. I can even turn the firewall back on and everything will be fine, that is until I leave work and turn the computer on at home. Then I have to go through this again. And then again when I go to work in the morning. I've tried deleting my router profile and resetting from scratch, deleting the network profiles in System Preferences and re-detecting. I don't know what else to try. It's an annoying problem.
Any suggestions?
Thanks.
Kevin

I think I have it fixed. One of the solutions I read about had to do with the 10.5.7 upgrade. I have always installed the smaller upgrades, not the larger "combo" upgrades. One tip suggested installing the full combo upgrade because, among other things, it re-creates two specific files that control how the computer interacts with the network. I installed the combo upgrade last Friday and connected without difficulty to the network at my office this morning. If I connect just as easily when I get home tonight I will consider the problem solved.
Cheers!
Kevin

6-month old Mac Pro has already had a new logic board and power supply

At a cost of $400 in shipping and a one-month wait, my 5-month old Mac Pro got a new power supply and logic board
Now I keep getting kernel panics, runaway kernel_task in Activity Monitor, and corrupted boot drives
External Firewire drives work some of the time, and occasionally my USB devices dont work either
This computer is a nightmare - how do I begin to figure out if this is OS (10.6.4) or hardware related?
The extended AHT test reports that all is OK - as does an extended memory test using Applejack
Should I do firmware updates and re-install the 10.6.4 combo pack, or am I just wasting more of my time?
I've got 4 macs and this is the only one that works badly - I think Apple's OS updates are getting as bad as Windows updates

My first question is why you spent $400 to get a 5 month old system fixed. That should have been covered under the warranty. So someone ripped you off, or you left out some key details.
And if you had both the logic board and PSU replaced, did you ever stop to think that maybe the problem lies with the power coming into your house? It's not really the big power spikes or blackouts you need to worry about, since those are pretty rare. What you need to worry about are the small fluctuations in voltage that happen several hundred times a day, if not an hour. Sometimes there's not quite enough power, other times there's a little too much, and all of this takes a steady toll on the PSU. It will do what it can to try and feed the rest of the computer a steady diet of electricity, but sometimes a jolt will get past it and start damaging other components. It could even cause data corruption on your HDD.
If the PSU and logic board already went, who knows what damage it may have caused to anything else. It may just be taking longer to show up.
It might also be that whomever ripped you off to the tune of $400 simply traded you one defective logic board for another. Or maybe they don't really know how to protect against ESD. I once saw a repair shop where the techs smoked in the same room they did the repairs. Sadly, for every one good tech out there, there's probably at least 3 complete idiots. Kind of like auto mechanics.
And I never have problems with Windows or Apple updates. Seems like on Windows the majority of people who have problems with updates are either running some program designed to change the way Windows looks or messes with low level system files, or they have a malware infestation they were unaware of/oblivious to. Most of the people who have problems with Apple updates seem to be the same way. They're running some truly bizarre programs that mess with the system in ways programs were not intended to mess with the system. There's generally a reason OS vendors provide an API for developers. You deviate from that at your own peril.

I am trying to connect to apple support and it keeps asking me to put in the SN of my MAC and when i do it says that the SN is invalid I am putting in the SN from under about this mac and it is the same as the one one the bottom of the MAC any ideas ?

Did you purchase this product direct from Apple online, in an Apple Store, or through a third-party authorized reseller? Or did you buy it from an original owner whose Applecare plan was supposed to be transitioned to a new owner, by them?
Do you have an original shipping carton the unit arrived in?
If the product was a retail 'open carton' purchase and no
back-track is possible, contact the reseller.
And if the computer had seen a major service with logic
board replaced, etc, it may have other issues with serial
number vs one they may have assigned it. Usually a
new logic board may have the SN flashed or if a unit
was determined to be a reman, a new # assigned. But
that would appear in System Profiler, if officially reman.
If you registered a product anywhere with Apple, it would show on a web page along with its serial numbers, going back several years, at this page after you log in there.
https://getsupport.apple.com/GetproductgroupList.action
A blue text with triangle See all products and services opens an Apple ID
sign-in window, then the page changes to show your items & info about them.
If you run the serial number through online Lookup, what appears?
http://www.powerbookmedic.com/identify-mac-serial.php
Not sure if this helps, 'your product' should appear - if registered.
Good luck & happy computing!

New logic board and now i-tunes music store and i-disk not able to connect

Hi,
My poor MBP died a few weeks ago - the Logic board went and took the Apple RAM with it (the Crucial one stayed fine!). As it's only six months old it has been fixed under warranty. However....
I've just tried to play some purchased music from i-tunes. It says no. It's also unable to connect to the store and attempts to connect or sign-in are refused. (An unknown error 11333). I trashed the old one, preferences and all and installed the lasted 7.4 but the same problem.
I-disk in System Preferences is also refusing to accept my password and connect even though I can go to it it via Go in Finder.
When I type in my password in System Prefences it says "Keychain not found: Keychain "login" cannot be found to store '******'"
I can see something of a pattern here but have no idea how to fix this.
Any help appreciated.

Open the Keychain Access in the /Applications/Utilities/ folder and create a new keychain, giving it the name login.

New logic board and now won't link to airport express

hi
I have a macbook which I bought in january, after 2 weeks I had various kernal panics and apple replaced the logic board. I picked it up yesterday and was using it at work on a wireless network all day, then I came home and tried to connect to my airport express and it wouldn't connect, it sees every other network in the building, but not mine (pre logic board replacement it connected fine). I reset the cable box, plus the airport express a couple of times but no luck, I then tried to connect my ibook and lo and behold it connects fine, I am on it at the moment.
I've restarted the macbook a few times, plus checked that airport is on, I've checked all my network connections, and they are fine. I've used airport setup assistant and admin utility, and it just can't see the express.
So does anyone have an idea how I can get my macbook to see my airport express?
I can find nothing wrong with it or the macbook.
thanks very much

Do you have access control (MAC address filtering) enabled on the AirPort Express (AX)? If so, you need to add the MAC address of the wireless interface of your MacBook.
Even better, disable access control. It offers no real security since the MAC addresses are easily discovered and cloned.

TS1367 Hi....I have an Intel based iMac.......serial # QP******DAS....I need a new logic board and power supply please ......can anyone help..........thank you

Can't get new logic board hint to work

after days of trying to resolve my new logic board problem of my time machine back ups not being recognized through using the terminal as suggested, i am giving up for now. i will keep my external hd and the info on it and just back up my important stuff to dvds for now. Is there any other way to get the info off my external hard drive back up so that it would make sense to my computer with a new logic board. Any program, etc.

I assume you are referring to this mac os x hint
http://www.macosxhints.com/article.php?story=20080128003716101&query=Time%2Bmach ine%2Blogic
You need to know some basic unix knowledge to follow this hint. If you can't make it work there is no other way to do it. there are no programs for that either. you should start a new backup sequence. You can still access your old backups via browse mode. control-click on TM in the dock and choose "browse other TM disks".

Is a new logic board revision confirmed? How to recognize it?

I have seen a lot of talk about a new logic board, and some sort of photo of a paper someone got describing that it required 1.0.4.6...
Is this really a new revision (which then fixes the whine and heat)?
How do you recognize it? I mean, does it have a name, or what do I tell the tech guys at my local service center here in Sweden?
Apple surely must have some stock of spare older logic boards left, and I really want to make sure that I won't receive one of those when I take my MBP in for service.

If your computer is still whining, then yes, you may absolutely be able to get your logic board replaced again. Your logic board was replaced once on March 29th but, as I now too can confirm, Apple released an even newer, revised logic board for the MacBook Pros during the last week of June.
If you are still experiencing the whine, call up AppleCare and simply be persistent and ask for a logic board replacement. If they say they don't know what you're talking about, simply tell them to look it up, as this is what I had to do. Once my Product Specialist sent an "escalation" to Engineering, he called me back within 2 business days and was able to directly confirm that there was a new logic board released recently, and we arranged to have my MBP sent in. And don't worry that your logic board was already replaced once. Mine too was replaced even more recently (end of May), but being as though this revision is very recent, it didn't matter. Just be polite but insist on getting a new logic board.
I however am still waiting on its return to verify whether or not my whine is gone. Turnaround time was amazing; MBP shipped overnight (over Thursday night, that is) and arrived at the repair depot yesterday morning and is on its way back to me as we speak! I should be able to report back on Monday afternoon...

HT1349 I received a new logic board and now my computer has no serial number under 'about this mac', and I need it to submit questions to apple. What do I do?
