2011 Macbook Air - Multiple logic board failures - possible causes?

I have a 2011 i7 macbook air - 7 months old. About a month ago I went to use the computer after allowing it to sleep and it was totally dead. Apple authorized repair center said the logic board failed and needed to be replaced. Fast forward a month and I finally get the machine back. It works fine for 6 hours, I put it to sleep, and soon as the screen went out, I hear a pop, fizzle, then the machine is dead again. The authorized repair center wants to replace the logic board again, which should get me up and running, but its not likley that that is the root CAUSE of the problem here, since it happened twice now. I suggested to them that perhaps the power adaptor, battery, or some other component is the issue and they don't think so. I'm located overseas, and every repair attempt takes 1 month b/c of parts (total joke if you're listening apple!!). My biggest concern is that they replace the logic board again, I'm out of commission for 2 months now, and it just fails again. Does anyone have any suggestions on the possible causes of this problem?
As FYI - I'm using the same power outlet and power strip with another laptop and haven't had any similar issues. Thanks for the help!

I have logic board problems too. I have had a late 2010 mac book air for 2 and half years. Its been a great machine in general - although it did go back within the warranty period for the track pad
Now it has logic board failure - symptons are the sound going and the battery is dead and it is unable to charge which means every time you put the power lead on the computer thinks it is starting from scratche.
I have been quoted over £400 for the repair! Like the above post I do not believe that this part should fail - and if it does then it is a major design problem and Apple should be doing something for us. I just dont know where to start.
I have used macs for 14 years and owned eight along the way. Most have them have lasted many years with full functionality the record was my G3 imac which was still working after 13 years.
I really cant believe the situation I am in and rather think I have bought my last mac!

Multiple Logic Board Failures... Advice?

My black MacBook is less than two years old. Starting this past January, I have had a total of three logic boards fail, along with other hardware failures, including the SuperDrive and Keyboard/Trackpad Module.
Every time the board fails, it is because of a different problem than the last time. First, a connection wire was faulty, causing the Super Drive to be replaced as well. The second time I don't know what was wrong with it, but it was replaced along with the Keyboard/Trackpad Module. This last time, the Speaker/Headphone connections were stuck, which again, caused the Geniuses to replace the Logic Board. The LCD screen was also replaced, but because of dead pixels. Also the hard drive quit working (thank god for backups). I am now on my 4th Logic Board in less than 6 months.
My computer is still covered by AppleCare for another year and a half, but the repeated servicing and re-registering programs is getting a bit ridiculous. Not to mention, if this keeps happening after the warranty runs out, it will be very expensive. I have no money to buy a new computer. The only reason I have this one is because I got it for my 18th birthday from my family.
Is there anything that I and/or Apple can do in this case?

Many things can cause a logic board to fail, from environmental problems to a run of defective parts used in the manufacture of a particular batch of boards. What you can do to help prevent problems are:
1) avoid giving your system (or any electronic device or component) any sort of static shock. Static electricity can easily damage solid-state devices. If in the area in which you have your computer you're regularly getting shocks when you touch metal or grounded devices, you need to take steps to reduce the static electricity buildup.
2) make sure you're properly grounded whenever you access the internals of the system, such as to remove or install RAM or hard drives, and install only quality components verified as compatible with your computer.
3) use high-quality power protection devices on the AC power to your computer and any connected devices (printers, scanners, networked devices, etc.) The $10 "hardware store special" surge protectors generally do more harm than good; get high-quality surge protectors or, better, a power conditioner or uninterruptible power supply with good power filtering.
Beyond that, it's rather the luck of the draw. But MacBooks in general have as good a track record of reliability as any laptop and better than many.
Regards.

Mid-2012 Macbook Pro Retina logic board failure

I have a mid-2012 MBP Retina, 256 flash, 16 gb RAM and after 14 months of casual use, the computer shut off one night and smelled like it was burning (it was in a well-ventilated place). I took it in and the logic board had failed. I paid the $310 to get it fixed and it's still having some issues with shut down. After talking to two apple store representatives and discussing it on the phone with an another, their opinion is that these are prone to fail. Has anyone else had similar issues and have they had luck with Apple getting these failure-prone components fixed?

The $310 repair if done by an Authorized service technician should have had its own warranty. Furthermore, if you can claim anything under the Exchange Repair program, you may want to see about this:
http://www.apple.com/support/exchange_repair/
In the future always buy AppleCare to protect against manufacturer defects up to three years from computer's purchase.
That failure prone opinion is in part because users may not know how to treat the cables*:
http://www.macmaps.com/frayguide.html
Given that is in the gray line between user neglect and manufacturer defect your mileage may vary on getting it repaired even under warranty.
If you can prove that you know what you are doing, and calmly explain the situation you are more likely to get it repaired when under warranty.
We are just end users here. So we can't tell you what will or won't happen for sure, or guess Apple's policy.

Two MacBook Air logic board failures in less than 8 months

Hi All,
I purchased a new MacBook Air in early 2011. 14 months later the logic board needed replacement. 8 months after that the logic board needs replacing again. I don't take the Air into extreme temperature/humidity environments. The computer has never been dropped or had anything spilled on it. This is the 4th latop I've owned since 1995, but all of my previous laptops have been PCs. Is this normal for Apple? Any suggestions on how to avoid yet anoter $280 repair (because of course the latest logic board failure is out of warranty from the initial logic board replacement 8 months ago...)?

Let me get this straight - you consider the need to have the logic board replaced twice in less then eight months on a computer that is less than two years old to be a good deal?!? Both logic board failures were diagnosed at an Apple Genius bar in person. It shouldn't matter if it was the hard drive, battery pack, or whatever. To have a major harware component and its replacement fail twice in a very short period of time is inexcuseable! I can understand the first failure - someone has to lose the quality control lottery. However, to have the exact same component need replacing twice strongly suggest shoddy manufacturing/rebuilding.
Are logic board failures so common on Mac Airs that the discussion is about the best repair price and not the frequent failure rate?

Macbook Air, Logic board failure, what happens to data?

Hello,
My Macbook Air died today with 90% battery and will no longer turn on. SMC and PRAM reset did nothing, it's completely unresponsive. I think it's a logic board failure. I have a question regarding a repair with Apple; I realise they will replace the logic board inside my computer with a new (or refurbished) board and the faulty one will be shipped to Apple. Considering the Macbook Air has flash memory on the board will this mean my data is now unrecoverable? I have everything backed up, I'm not worried. I have some err personal photo's of me and my partner in iPhoto and I'm wondering what will happen to the sensitive data.
Thanks for dealing with this lets say awkawrd topic

I don't think that your flash memory files are unrecoverable. That's because the logic board of the MacBook Air hasn't got the flash memory soldered. However, I don't know if Apple will replace the logic board, "recycling" your flash memory, or if they will install a whole new logic board replacing the flash memory, although the first option makes more sense and it would be the normal option.
Anyway, as you have a backup on an external drive, you don't have to worry about that

MacBook Pro won't start up... possible logic board failure?

I bought my MacBook pro in March 2008, 15 inch, and it is now out of apple care.
It freezes on start up on the white screen with the apple logo and the spinning thing.
Did hardware test and got error code 4SNS/1/40000000: TC0D - 107.500
Is this a logic board failure, or possibly something that could be fixed much easier and cheaper?
Thank you for any help.

That error code is listed as a hard drive sensor error. It may mean that the temp sensor on the hard drive needs to be replaced, or the logic board might be at fault.
It could also get caused from another fault peripheral device as the code describe generally a "connection fault".
You should remove usb mouse or other usb devices and try to boot in safe mode to eject all attached drives proper.

Logic board Failure after 2 years - Macbook Pro 13''

Hi! Does anyone had problems regarding logic board failure on Macbooks Pro 13''?
I've bought mine 2 years ago and it started to fail. I took it to the technical support and was told that the logic board was damaged and it had to be changed. The warranty expired last november, so I have to pay for it. The problem is the logic board costs almost the price of a new macbook pro.
It is not possible that Apple think it is ok that a notebook that expensive lasts only two years.
I'm in Brazil and here there is no Apple store. So I'll probably have to buy another laptop ( and sadly I don´t know if I'm going to buy a mac again... not with it lasting as little and being the parts so expensive. )

Hi! Does anyone had problems regarding logic board failure on Macbooks Pro 13''?
I don't have the problem, but it's been percolating on another discussion for several years now:

You might think about posting there, too, so others can read about your issue.

MBP 2011 logic board failure

Hi!
I had a logic board failure a while ago. i got it replaced and now i just had the same issue that i had just before the crash of my previous board.
I have a late 2011 mac.
so this is what happened first:
i was working in photoshop cs6 and my display suddenly moves for about 10 centimeters to the left. the left side shifted to the right side actually. and there were artifacts everywhere.
i rebooted, all was fine again, but soon thereafter it happened again, and again, every time on booting photoshop, and after that my macbook just stopped loading at the apple screen, and it had horizontal green lines.
i was told that my graphic card crashed that was on the logic board, you know the drill.
when it crashed i was scanning an image.
so today i was working in indesign cs6 and i was printing when my screen shifted again. i rebooted, all is fine. i noticed that i was using the same (old) USB cable as when i first got the crashes.
i was wondering now, could it be that an external USB device, or cable, could make a crash and even kill the logic board? i paid 650 euros for a new logic board and sure as **** want this thing working properly now.
thank you alot!
Mathieu

Please ***Send Feedback to Apple:*** This is the most important. IF there is going to be a replacement program, you're going to have to start an official case with them. Might as well do it now. This will also help Apple diagnose the issue (we want a permanent fix, right?). They probably already have, but officially document your case!!!
Everyone should write a registered letter to Apple reporting an official complaint:

I got a mid 2011 macbook air 13 with 128gb ssd is it possible to upgrade my storage?

i got a mid 2011 macbook air 13 with 128gb ssd is it possible to upgrade my storage?

It is entirely possible, as many have known from day one (as ifixit's first teardown revealed). Unlike the unupgradeable memory, the SSD is a discrete expansion card that is removeable with just one screw, after removing the case cover. It is however debateable as to whether such an expansion is worth the possible risk of making demonstrable changes to the MBA whilst still under warranty. So you may want to stave off consideration for a while.
I made the upgrade recently on my older 2010 MBA, and it was easier than upgrading the HDD on my old MacBook Pro.

IBook G3 start-up issues, possible logic board failure?

For the past few months the screen of my iBook G3 has been skipping and flashing and jumping at random times, quite often. If I move the screen to and fro it usually stops. I assumed this was just a bad connection with the LCD display and have basically ignored it.
Today, however, my screen froze completely while I was running Safari. Even the finder was frozen so I had to turn off the iBook by holding down the power button. When I restarted, it went through the usual start-up motions but after the grey start-up screen, it went to a blank blue screen. Only the mouse's cursor showed up at this point and nothing else. I was not asked to log in. Nor could I see my desktop.
I was just now browsing this board and found that the jumping screen issue I've been dealing with may have been logic board failure. Could this new blank blue screen problem also be a symptom of that? Or is it part of an overall hard drive failure?
The computer is quite old. I bought it in early 2002 and there's only about 2GB of space left on it at this point. So is it possible that the hard drive has crapped out?
I'm trying to restart right now in safe mode but it's been stuck at the grey start-up screen with rotating dial for about 40 minutes. Don't know what to do and I'm a little distraught at the idea of possibly having lost all of my files.
Any advice is appreciated. Thank you very much.

Hi, Christopher. Welcome to Apple Discussions.
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
If Safe Mode doesn't work, you will need to try repairing the hard drive from your Tiger Install disc.
Every time you have to do a forced shutdown instead of a normal one, there is a chance of hard drive damage and you should repair the hard drive, either by booting into Safe Mode OR by starting up from the Mac OS X Install Disc by inserting the disc and restarting your computer, holding down the C key as the startup chime is ending. Then click 'Next' at the language screen and choose Utilities > Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with either Safe Mode or the Install disc's Disk Utility, then start up normally and repair permissions from Disk Utility in the Utilities folder on the hard drive.
Here's hoping that a little hard drive maintenance will help. Good luck.

MacBook Pro Retina Display Logic Board Failure

There are a lot of threads discussing the logic board failures in MBP's. I have a brand new MBP with Retina 2012 that failed due to a bad logic board. Apple is replacing the machine, but is this a bigger problem others are having?
Data backup/recovery has been an issue since Apple's policy prevents users from retrieving data from the working and intact solid state drive (SSD) attached to a broken MBP. It seems ridiculous, but it is true that Apple stores are NOT equipped with external enclosures to read data from a SSD like a spinning HD.

Can you upgrade your mid 2011 macbook air ram?

Yes you can upgrade the ram of the mid 2011 macbook air, today I just asked an apple genius and they said they can but they cant do it in stores, they said it will cost approximately $200 but if you do it, it will be cheaper.

The guy also said that he upgraded his. He also asked other workers about upgrading the RAM and they said yes you can, but maybe he thought I was talking about a macbook pro. I think what he meant was to change the logic board.

Get files from old MBP to new MBP when the old one has suffered a Logic Board failure

Recently, my 2009 unibody MacBook Pro died. Logic board failure, I am told. It is out of warranty, and replacing the Logic Board would cost a grand. It had some other issues too, so I figured upgrading to a brand new system would be the best idea. So, I am going to purchase a brand new one within the next few days. My question is this: How to I get the files from my old MBP (I NEED them, plain and simple) to the new one once I get it? Should I take out the harddrive from the old one and connect it via a SATA>USB cable and connect it to the new one? Can anyone shed any light on this? It will be much appreciated. Thanks.

Yep, all you need is a IDE/SATA to USB adapter for about $20 online at OtherWorld Computing, NewEgg and other online computer sites like Amazon etc.
You can find the screwdriver or other torx driver at iFixit or OtherWorld, just look for your Mac model or just be rough with it and drill out the screws.
You can choose to get a enclosue and use the drive as a external drive, it will cost more naturally, but for a few bucks more though you can get a brand new external drive and likely twice the capacity.
Some external drives can't be Carbon Copy Cloner and option booted from, so perhaps a adapter is best. (don't clone a OS from another Mac to your new Mac)
Setup:
When you set up the new Lion Mac, name the hard drive the same name as the external drive, also setup the same user name as the old Mac had. Software Update.
Install all your known third party programs from fresh sources as many as possible.
The last thing you do is connect the old Mac drive, transfer all the files from the user folders right back into their respective folders on the new drive (Music, Pictures, Documents etc) Not User/Library.
Open all your programs like iTunes and iPhoto and it will update for your files, then go through the folders and delete what you don't want.
Don't use migration or setup assitant, it's a blind copy, includes programs you can't use anymore and other headaches.
If you do things in the order I specify, your drive will be optimized and run fast for a decent amount of time.
If Lion act's glitchy, Carbon Copy Cloner to a new HFS+ Journaled (Disk Utility) and then hold Command R to get into Lion Recovery, Zero Erase the OS X Lion partition and then option boot from the Lion clone and reverse clone onto the OS X Lion partition on the internal.
You can also reinstall Lion on top of the factory Lion from the Recovery Partition.
search "apple support Lion Recovery" for details.

Mid 2011 Macbook Air Painfully slow.

Mid 2011 Macbook Air Painfully slow.
Hey everyone. I am writing about my 13 inch Mid 2011 Macbook Air.
Recently it has been extremely slow and on occasion has not started up.
I have reset the PRAM and SMC already, yet it is still very slow. I have a couple theories about what might have caused it, are they plausible?
Theory 1: It’s a software problem. I tried to upgrade to 10.8.2 but halfway through the upgrade the computer restarted and somehow I was still on 10.8.1. For fear of a big issue happening I didn’t try to upgrade again. Perhaps it is a flaw in Apple’s software update?
The important thing to note about this update is that I tried to install 10.8.2 around a month or two weeks BEFORE I started having problems. So if these issues were due to 10.8.2’s failed update then it certainly was a delayed reaction.
I would of course like to update to 10.8.2 BUT as my computer is acting EXTREMELY slow and having trouble turning on occasionally I am worried the software update will completely brick the machine. Is that possible? Should I actually finish through with the software update?
Theory 2: It was an electricity problem.
The computer died when I was sitting at a café plugged into their wall sockets. A few days later when I came back to the same spot with my old macbook which is now being used in lieu of the Air it suddenly turned black for a little while. Sensing it might be an electricity surge or something with their system I unplugged the cable. I am not sure if that was paranoia though.
Can an electricity surge or a bad outlet fry a computer? Can it fry the ram so the computer is extremely slow? Does that theory hold any water?
Thanks for your help diagnosing this problem.
All the best.

This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.

My mid-2011 MacBook Air bricks itself after 10.7.2 update

I have a new MacBook Air (11") that was working just great, until today. Today, I used Software Update to install the updates, which included 10.7.2 as well as the recue partition update.
I did everything you're supposed to do, and when it rebooted, the gray screen comes up, and it shows the spinny doohickey on the bottom showing that it's working. Then, suddenly, up pops a big "no" icon (the circle with the slash through it) after about 60 seconds.
It simply doesn't do anything after that.
Hard-power-off, wait, power-on, repeat, same thing.
So I reboot with cmd-R to get the rescue partition. It works fine; I ask it to re-install Mac OS X, which then takes about 45 minutes (argh). Finally, Mac OS X is back, the machine is nicely booted up, all my files are there, everything is good.. But of course, the reinstall took me back to 10.7.1.
All I want to do is upgrade my fricking iPhone to IOS 5.0, but I can't do that without knowing I can sync which requires iCloud which of course requires 10.7.2. So I *have* to re-do the upgrade.
Back to Software Update, back to installing 10.7.2. And .. 20 minutes later .. back to bricked MacBook Air.
What a waste of my time. What a failure, Apple. I'm very very very very very unhappy that I've wasted so much time just to update my damned iPhone to IOS 5. I'm still without an update. Now I'm trying to figure out how to move my iTunes to another machine -- not nearly as obvious as it should be. ARGH. I'm going to throw this MacBook Air off the balcony in about 10 minutes. :-(
Thanks for listening.
Steve

Wow, you're right -- I can't believe it. I just really can't believe they would screw up so badly, yet when I search for "10.7.2 filevault" I don't find more than a couple of articles about it on the web (including this thread). Why on earth wouldn't Apple have put up some kind of warning about this? I can't believe it, really. It's insane.
On my newly-functional 10.7.2 MBA, I wanted to test your theory and so I turned on filevault 2 and encrypted the main disk again. It of course wanted me to reboot. So I rebooted. And *blammy* -- same error / boot failure. Wow. Also, interestingly, even on a working 10.7.2 system, you can't mount a USB drive that was encrypted using Filevault 2 encryption (in Disk Utility, e.g., as a "Mac OS X, journalled, encrypted" volume that was encrypted with DiskUtility on Lion 10.7.1). I still have a 10.7.1 machine that I will not upgrade until I can at least decrypt the disk -- but right now, Disk Utility tells me it fails decrypting the external USB disk so I'm hosed!!! ARGH.
Now, going back to the booting problem after upgrade -- for anyone's reference who's still keeping score -- you can easily recover from the booting problem with upgrading a Filevault 2 root drive: Power-cycle the machine and then hold down cmd-r to bring up the Lion Recovery application. Within Lion Recovery, choose "Disk Utility", and then click on the (as yet unmounted, still encrypted) root hard drive to select it. Then go to the File menu, and choose "Turn off encryption" for this disk. It then prompts you for the password, and if you enter it, *blammy* you're back up and running again.
In my case, the disk had only just begun encrypting so the action was instant, and then once it confirmed the disk was now decrypted, I simply chose "Restart" from the Apple menu, and I was back in business (no hairy re-installs to deal with). If this is an already-encrypted volume, presumably it'll take you a bit longer (the normal 45-minutes to 2 hours) to decrypt it. But at least no more installing software -- it'll "just work".
Maybe I'll go post a simpler version of these instructinos on the other threads, but this is the simplest fix -- just turn off filevault 2 from within Lion Recovery, basically, and that fixes the boot problems.
Apple, if you're listening, you really really really need to say something to your users so they know. Many many many MBA users are likely to have still not upgraded. You can prevent them from hating you and your products by making sure they don't screw the pooch here. Short version: Mid-2011 MacBook Airs running Filevault 2 WILL NOT BOOT after 10.7.2 update; so users should turn off Filevault2 before upgrading.
