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.

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

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.

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

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.

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 and software update, MacBook Pro is spontaneously shutting down and preventing restart. Inconsistent ability to restart after multiple tries. What is going on?

Hard drive sensor or logic board failure.
Try a SMC Reset, only thing I can help.

Check your tones with this sounds like it's not recognizing the RAM, perhaps it's not seated well or making a bad connection or it's defective.

Logic Board replaced after randomly shutting down

I know there are a lot of posts on the randomly shutting down issue...
My MacBook started randomly shutting down after a month since I got it. Apple replaced the logic board and I got it back today. I read on some posts that people got their logic boards replaced and the problem continued. Is this likely to happen with my MacBook?
This seems to be a big issue. My friend got a MacBook last week and it started randomly shutting off within the first hour of use. He had it exchanged, and it's fine now... but for how long?

I don't think it would do any good to yell at the store manager/technician. Still, I do understand you since I got the same problem here. However, since my logic board was replaced, I got fewer RSD, which is a start...
Personnaly, I know that my MB is guaranted 1 year, so I won't hesitate to have it repaired, or exchanged if needed (after 3 repairs for the same problem usually). As a matter of fact, other than some RSD, my fan has started making noises when I power up my MB, when it is cool. I wait because there is no solution out there yet (for RSD, and my problems are not that bad.
By the way, reading many of the threads around here, we can almost state for sure that:
-the logic board
-the RAM
-the hard drive
-the heat sink
-the battery
are not the (direct) sources of RSD. This has to be proved for the processor and the fan.
To be followed...

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.

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.

Error: 4SNS/1/4000000:TGOD after logic board replaced

Hi there -
I got my MBP back today, after having the logic board replaced to resolve the nvidea graphics card issue (http://support.apple.com/kb/TS2377).
After working with it for about 40 minutes the screen went blank. I ran the Apple Hardware test on restarting, and got the following error code -
4SNS/1/4000000:TGOD
I've given it back to the guys who repaired it for further testing. They said that their diagnostics arent showing anything, but the Apple Hardware Test has come back with this error each time. I've searched around for information on this error, and there are suggestions ranging from issues with the logic board to a thermal sensor issue.
I've found 2 threads in this forum where people have experienced the same sequence of events - logic board replaced for the nvidea problem, only to get this error code when the laptop is returned.
http://discussions.apple.com/thread.jspa?messageID=8633584&#8633584
http://discussions.apple.com/thread.jspa?threadID=1850653&tstart=0
Can anyone shed any light on what the problem might be? Has anyone else had the same issue?
Any feedback would be appreciated.

I can't find the thread, but I do recall one case where the person got to talk to a product specialist, who said that the sensors sometimes do not get precisely located where they should be after a logic board is replaced, as well as sometimes not being securely plugged into the logic board. I don't think the AHT error should be ignored. If the local guys can't figure it out, it may need to go to Apple.
Good luck!

Noisy fan *after* logic board replacement

I started having the problem with my fan ranging from intolerable to sounding like it's about to take off after my logic board was replaced by Apple a couple of weeks ago pursuant to the GeForce video problem. The problem started Friday.
There are no problems with temperature, cpu processes (when 90% idle) or anything else. I have reset SMC and PRAM. Firmware was updated and computer passed the hardware tests at Apple today, yet the problem persists intermittently unchanged. It sometimes starts when I move the laptop, which normally rests on a coated wire shelf above my lap.
Did Apple do something to the fan when they replaced the logic board? What else can I try?

Welcome to Apple Support Communities
It sounds like they forgot to reconnect the temperature sensor lead(s) so in this situation the fans run at maximum 'just in case'. You can check if this is so by running the Hardware tests from your install DVD (hold d and Boot from it) and see if it reports SNS (sensor) errors, if so get it back to Apple and have them recheck the leads and connections.

After having the logic board replaced, Time Machine will no longer backup my computer to the same backup files as before.

After having the logic board replaced due to bad NVidia chip, my Time Machine will no longer backup my computer to the current backup. Is there a way to reset something to get Time Machine to continue to use the same backup files as before for this laptop?

As far as TM is concerned you have a new computer, so it will make a new backup. If you don't have the space for both backups then erase your backup drive before backing up the computer.

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.

TM error after logic board replaced

hey guys,
I've got a strange one. I had to have my logic board replaced in my Macbook Pro due to a nVidia graphics card dying. Time Machine was working like a champ before I dropped it off. When I got it back I got a TM error and it doesn't want to backup now. One thing that seems strange is that when I open a Finder window and then launch Time Machine, it's looking for files for Jonathan's Computer (2) instead of just Jonathan's Computer. (Yes, I'm Jonathan.) So it seems to be looking at some sort of duplicate or something. My backup files are on the TM drive and are searchable via Finder. However TM won't backup and I can't restore anything.
Any thoughts as to what may have been borked and how to fix it? Thx.
Jonathan

However TM won't backup
Why not? It's likely because the extra full backup has filled your TM drive.
See item #C2 in the Time Machine - Troubleshooting *User Tip* at the top of this forum.
It will show you how to locate the message(s) that describe the problem, then help you fix it.
If that doesn't help, post back with details, including all the messages, your setup (especially the destination for the backups), what you've done, and the results.
Also note #C8 which addresses the Logic Board problem.

Loud fan after logic board replaced

I just had the logic board replaced on my 17" iMac after it would not power up (apple did it for free because they said it was one of the defective boards). The fan now is VERY loud. I have tried reseting the SMU, setting the CPU speed to something other than automatic. Nothing seems to work. Top say the machine is idle 95% of the time... Before the board was replaced it was VERY quiet... Any ideas?

fxmBoston-
Greetings and welcome to the Apple boards.
Miriam is right. Take it back and have it repaired correctly. We have good consumer laws in MA so they have three chances to get it repaired correctly or they owe you a refund or a new machine.
Be firm yet polite.
