Logic board needs replacing..

So about a year ago I had my 2011 21" iMac plugged in and in sleep mode, when the power went out due to a storm. The morning after I tried to turn it on and it wouldn't start up, so I checked the Internet and it said to check if it was the power cable which I checked, and it wasnt that. I scheduled an appointment at the Apple Store and they checked the cable and confirmed that it wasn't that and said they would check the power supply, and it wasn't that either. They then told me I would need to have my Logic board replaced, which I DO NOT have money for, so I took it home. I then brought it to my girlfriends dad who fixes computers, and he just took a cable from a broken printer he had and it ran, but he said it took a little while to turn on after pressing the button repeatedly. So he brought it back to my house and after pressing the power button over and over with no luck, I left it. About an hour later I went down and it was on, and I ended up using it without any issues. It went on like that for the few times I had to turn it on after a power outage or whatevet, only noticing that it ran a bit hotter than it used to. So today my town had scheduled for a temporary power outage due to maintenance, and I powered down the the computer just in case and when i returned later to power it back up, it wouldn't turn on, so now I'm hoping it will be on when I check later but my question is, if i needed a logic board replacement, would the computer still power up eventually and operate as smoothly as it does?

Power problems can cause havoc.
1. make sure that the Energy Saver Preferences, "Start up automatically after a power failure" is unchecked.
That way it will not try to startup on it owe when the power comes back on.
2. given all the weird problems, I'm surprised that you forged on to Yosemite...?
First thing I would do is make a new bootable backup clone on one of my external hard drives. That way I could do more testing, including wiping the OS X from the HDD and starting over.
3. run the Extended Apple Hardware Test @ > Using Apple Hardware Test - Apple Support
If the Hardware Test does run from the version on your HDD, run the Hardware Test on your original Snow Leopard set.

Apple says "logic board needs replaced" because MBP won't turn on w/o SMC reset but I think I can fix it; can you help?

Hello,
Less than a year after purchasing a brand new, early-2011 Macbook Pro (still covered under Extended Apple Care) and, sadly, only a week or two after finally upgrading to 8GB RAM, I returned to my notebook after taking a shower and watched it suddenly shut itself down. It has not been responsive to the power button since then (although, see below.. I think I can fix it).
Genius Bar took one look at the visible moisture sensor you can see underneath where the RAM sits and declared it water-damaged. While I agree that either a short and/or corrosion is causing my MBP to malfunction, I don't believe it should void my warranty because the problem isn't that I spilled something on it.1
I hope someone can give me some insight into fixing this myself. Apple says "the Logic Board needs replaced" (a common CS response, I've noticed) the water damage voids my Extended Care + that it'll be at least $1200 and several weeks. Here's the situation:
MBP will not turn on just by pressing the power button. However, MBP consistently (every time) powers up when I do an SMC reset.
I have it in verbose mode and it begins booting. But, it will invariably turn off without warning anywhere between 30 seconds and 8-10 minutes after powering up.
MBP will not turn on just by pressing the power button. However, MBP consistently (every time) powers up when I do an SMC reset.
I have it in verbose mode and it begins booting. But, it will invariably turn off without warning anywhere between 30 seconds and 5 minutes of powering up.
Eighty percent of the time, it turns off during the pre-Xorg boot. However, I have also seen it fully boot, I log in, I'm able to peruse logfiles/etc. Safe Mode (holding shift) crashes early. Single-user mode makes no difference. PRAM/NVRAM/etc makes no difference. I can boot to the Recovery Partition but it turns off just the same (disk utility scan takes too long).
I haven't been able to really test the Internet Recovery because the hotel wireless takes too long. I did boot into Hardware Test and it passed the basic and extended tests (although it seemed to just be testing the RAM integrity.
I can boot from the optical drive with a FreeBSD 9 livecd and an Ubuntu 11.04 livecd. Of note is that the laptop shuts off consistently when FreeBSD begins the journaling services for the ZFS filesystem (every time).
Here is where this leads me to believe I'm at (I am not dogmatic here and would appreciate any corrections or insight):
It seems like there may be corrosive damage on the logic board but maybe it's isolated given the various consistencies in what's happening. It seems like whenever SATA is use, I lose power. When SATA isn't really used (the HW Test), the laptop has literally stayed on for days and days.
I want to get in there and clean up any corrosion with 91% isopropyl alcohol (9% distilled, non-conductive water).
I want to use a bootable OSX livecd with an "emergency console" so I can, basically, use boot options to step throught the boot process and see if I can isolate the problem.
Here is what I'm uncertain about and could use guidance:
Does any of this sound remotely reasonable to anyone who has been through this or am I delusional?
Any tips on identifying and cleaning any corrosion?
While I had made a bootable version of Lion via Disk Utility and a rescue disk with some third-party app, they are MIA and I don't have another Mac at the moment. Do I have any other options? Again, an install dvd is not exactly what I want -- more like a rescue dvd. I had read about some Apple Stores giving/copying bootable USB thumb drives like this to customers. But, I noticed that this is now on sale there for $80. I would use this like once and, ideally, could use my MBP to make more. $80 seems a bit much.
I should be able to step through the boot process in a way like what's possible with FreeBSD, no?
Anyone have any other specific troubleshooting tips?
I really, reallly need my MBP back as soon as possible. I'd really appreciate any wisdom and insight! Thank you,
-ryan
To be totally honest, about 3 weeks prior I spilled some milk from cereal on the desk and a little bit got onto the battery. However, the notebook worked fine for the following weeks. I believe that the problems have been caused by ambient humidity ... I've been staying in a hotel that steams up the entire room when I take a shower. The windows are covered in water droplets so why wouldnt the MBP be affected? As noted, these problems began after I lingered in a hot shower.

I don't think you have a case.
You can replace the logic board yourself if you are a DIY'er and save some money.

My logic board was replaced on my Mac and now my CS4 will not open. I re-downloaded it, gave the serial number, but it still won't open. Now what?

My logic board was replaced on my Mac and now my CS4 will not open. I re-downloaded it, gave the serial number, but it still won't open. It said that the licensing had expired. But this is not the case. Now what?

uninstall, clean (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6) and then properly install (do not migrate, use timemachine etc) using the installation files.

My G5 died... new logic board needed... What do i do?

Ok, here's the story:
The other day, my G5 crashed when i wasn't using it (screensaver).
I hard rebooted it, fan started to spin, power light flashed only when i pressed the button and then no screen. After a while, fans started at full speed...
Tried loads of things (reseat memory, PCI cards etc...), nothing worked.
I took it to the local Apple Certified Service centre. They called me after half a day to tell me that the Logic board had a problem and needed replacing and quoted £585 inc vat!
No need to say that i am pretty upset as i paid 1400 3 years ago for that machine!
Now, what are my best options?
This is a dual 1.8 G5 (early 05) with 3Go ram and 2 SATA drives. I have 2 standard Pci Cards for music in it (RME audio card and UAD-1).
Should I get it repaired?
Should i buy a second hand G5 (which would cost the same sort of price but with the risk of having a problem as well)
Should I go for a new or newer Mac pro but can i reuse my memory, PCI cards, disks etc???
Thanks a lot for advice.
Laurent

Hi tek_uk,
Welcome to the forums.
Your mac is one found in either of these model series. Anything you have now on your mac would work for both series and if you chose to go with one of the faster models listed you could easily do that.

Replace logic board... There must be a special course at Apple training schools in saying that.

How many logic boards needed ?!!

Yes. How many logic boards does a Powerbook G4 17" (1Ghz) need to work properly? Do they really have to be changed every year?
I bought this beautiful machine secondhand. About 6 months later the screen seems to fail (stays black) i can us it only in Target mode as hard disk. The consulted Repair centre concludes: new logic board! Then they discover it already had been changed 26/07/2004 ; merely a year ago. But no more garanty. It isn't fair that such a expensive part and repair is only garanteed foor 3 months. Cost of this reparation: more than 700 euros !!!!! Apple customer care: "sorry, we can't do anything to help you" Who can then?
Time to switch I suppose? What else can I do ??

Sorry to hear that - not sure if you have any recourse based on the fact that it has already been replaced. If you have an up to date AppleCare contract then I would think it should be covered. In general I would say that your problem is somewhat rare. If main board failures every 6 months were common across the entire product line - or even just a subset such as the 17" - then there woudl have been a class action lawsuit resulting in a settlment that woudl provide extended warranty coverage.

Ethernet port dead- new logic board needed?

The ethernet port on my 2010 iMac 21.5" died after a storm last week, so I brought it to the Apple store to have it checked out. They said it needs a new logic board since the port is connected to it, which will cost around $700. I can't see spending that much money to fix it, anyone have an ideas on where I could sell it for parts? The guy I spoke to at the store said to give it a shot

Is your wireless still working? You could connect your Mac over Wi-Fi instead, if you still wanted to use the Mac, that is. Or use a USB Ethernet adapter. Apple sells one for $50 that was primarily for the Macbook Air, but will work with any recent mac. But if you already have Wi-Fi, then I'd try that. And if you don't have Wi-Fi, it still may be useful to try Wi-Fi first because even if the Mac's Wi-Fi doesn't work, you can still attach other computers or devices like iPads or iPhones, etc. Whereas it would be a waste to buy the USB ethernet adapter only to find out that the USB ports on your Mac were also affected by the storm.
Otherwise, as usual, you can always sell on eBay & Craigslist.

My MacBook pro has been having Internet problems after logic board was replaced

I have an early 2008 15.4 inch 2.4 ghz MacBook Pro and just had the logic board replaced because it died on me. Ever since I got my MacBook back I've been having problems with my Internet (wifi). My connection seems to be good I get the full bars but sometimes when I'm browsing it'll take forever to load. The ball just keeps spinning and I have to keep trying to refresh and nothing will load. Other times my Internet works perfectly fine. I don't get an error message about not being connected to the Internet..and I don't think it's a memory issue. Could my logic board replacement somehow be related to my Internet issue?
Anybody ever have this problem?

I would call the facility where your mac was repaired and let them know a new issue that was not present before the logic board replacement is occuring.

My logic board was replaced and now Logic is asking for my serial number again - I don't think I have my docs for Logic anymore, what can I do?

I've had my Logic Pro software for years now, and since I got my logic board replaced, Logic won't open without re-entering my serial number, which I don't think I have anymore! What do I do? Help is greatly appreciated!!

Logic Board Needed

Hi,
I have recently discovered that my 2 year old powerbook requires a new main logic board. The Apple part number is 661-3481. Does anyone have an idea where I can get one and how expensive it would be?
Thanks,
Abboud

Hi Abboud,
Welcome to Apple discussions.
You don't state which TiBook model you have, but depending on the speed, prices usually range between $300-600. Note: installation is not easy, so make sure you're willing to spend the money and time/effort before going this route. The money may be better spent on a used/working TiBook or a new MacBook.

Logic Board was replaced - Now Time Machine does not show previous backups

Hi
Bit desperate here.
My Apple store changed my hard disk and the logic board along with it.
I'm now aware that this means my MAC address has changed - which is what your Time Machine looks for when it tries to back up.
So now the backups are failing, and I KNOW there's a HINT offered on macosxhints.com
http://www.macosxhints.com/article.php?story=20080128003716101&query=Time%2Bmach ine%2Blogic
- but I have absolutely NO previous experience with TERMINAL and minute I try to re direct terminal to my Time Machine Volume : it tells me there is no such file or directory. It's all gobbledygook to me. I think the person that wrote it ASSUMED some previous knowledge of using terminal.
The things I DO know are: My MAC address number, and my TM Volume is called The BIG BACKUP (not Time Machine). It doesn't
Can anyone make this clearer for me, or indeed is there an easier way.
I know I could just tell TM to change disk and just star afresh - but I'm under the impression that it's very uneccessary for me to lose all my previous backups.
Hey, many, many thanks if you can help
Simon

Hello K.V.
(I'm having to come back to this when I get a minute at the moment)
Many thanks for your suggestions so far. Several things have occured:
Firstly I did what you instructed in your last post, that seem to let me go on without any further errors - so I then when back to my desktop - dismounted The BIG BACKUP and restarted the whole mac, remounting the The BIG BACKUP. I went to the 'Back Up Now' commend to test it and it failed, sayind it could not find the file or directory.
So this evening I started in terminal from scratch - when I got to the ls -al command I noticed that my old address was no longer in the list, it was on the line before the new address before (I also punched in the wrong mac address intially but spotted it and rectified my mistake .001f5beb34e5 being the correct one) as you can see from below it now says my old address is No such file or directory.
Here is a copy of what happened

Very confusing huh.
To be honest now, I guess my prime concern is if I've made any damaging changes to things I don't understand or not - and I think it may be best if I accept the Time Machine starting afresh from square one by clearing the external drive and re-directing TM to it. I could live with this I guess, so long as it worked.
What do you think?
Many thanks

AHT finds logic board error, but computer working fine

I ran the Apple Hardware Test to see the profile for my RAM, but 7 seconds into the test it stopped and reported a logic board error.
1. But my computer is working fine. If anyone has experience with this, I'll gladly take your advice. Do I ignore this error at my own risk? Or should I get it looked at now in case it's an early warning of something that can get worse? For the real Apple tech experts, here's the error code: 2I2C/1/1: 0x00000092.
Eleven months ago, I had to get a new power supply installed. It was covered under the extended warranty for power issues with iMac G5s. As I've indicated, it's been working fine since then.
2. Once AHT finds an error, it won't continue testing the remaining components. Does anyone know of a way to "force" the AHT to skip the logic board test and go on to test the other hardware items?
Thanks all.

Michael, pray tell, where does one find the published list of codes you refer to? I searched the whole internet (or so it seemed like it) looking for a resource like that. Are you an AASP?
Even my experienced Apple technician and his AASP contacts didn't realize that my error code relates to the European Union. (And, BTW, I'm in Canada and I purchased my iMac from a store in Canada.) You have solved a mystery!
The strange thing is that when I phoned Apple Tech Support and asked to speak to a product specialist, even they told me that the code means "logic board needs replacement." When I asked to speak to a higher dept., I was connected to Customer Relations (very nice, professional fellow answered). When I explained that this G5 iMac has been problematic for me (failure after 7 mos. of ownership, power supply failure after 3 yrs, etc.) he offered me $100.00 off a new iMac ($125.00 in Canada), which I accepted.
I did use TechTool Pro to check the computer. It found no problems. Four months later and it's still going strong. I don't know whether to be upset with Apple for not bothering to look up the code, or whether I should look at this as a blessing in disguise (how else would I have received $125.00 off a new iMac? And now, my father gets a G5 that I can confidently say is in good working order). And it's strange that my local tech's AASP friends weren't any wiser. Aren't AASPs privy to this error code info? A mystery indeed...

IMac G5 (2004) logic board and the repair extension program

Hi,
I know that there are tons of topics about logic board/power supply troubles witht the first generation G5s, and I'm sorry to start yet another new thread, but I still have some questions about this issue.
I have a first generation iMac G5. Long story short...when I first got it the computer would shut itself off sometimes after I had put it to sleep. When I would try to restart nothing would happen, but usually letting it sit unplugged a while would solve the problem (occasionally when I'd restart a different start up noise would sound and the white light would flash quickly). It happened so randomly, that I just lived with it, blaming the problem on my dorm network, or a power failure. A few days ago I tried to start the computer up and nothing happened (just a VERY faint sound like a clicking or ticking or intermitant humming...definatly electrical sounding). I unplugged it overnight, but the next day still nothing. I decided to go through the troubleshooting steps Apple lists online. The internal power button could not start it up and the second LED does not flash, which according to Apple means the logic board needs replacing. Luckily my serial # is covered by the Repair Extension Program, and I'm bringing my computer in tomorrow morning to be fixed (just in time for back to school).
I have become concerned, while browsing the discussion topics, that this fix may not be permenant. I've read a few posts that claim that they are on their third Logic Boards, and this kind of scares me. My parents bought me the computer (our family's first ever Mac) and did not purchase the AppleCare extended warranty (they had heard how reliable Macs were...hmmm.) I didn't even know that I could purchase AppleCare after-the-fact until it was several months after my 1yr warranty expired. I do appreciate the fact that Apple recognized what seems to be a common problem with this generation of iMacs, but I wonder why they did not contact the owners of these machines to let them know that the problem and repair extension even existed.
So I guess my real question is...Does anyone know if, after this repair Apple will replace the logic board if it dies again? Is there a limit to the number of qualified repairs you can get through this Repair Extension program? Also is there any other Extended warranty type thing I can purchase after my 1yr. warranty is up.
Sorry the post is so long...I'm just scared about the fate of my beloved Mac.
iMac G5 (2004) Mac OS X (10.3.9)

Oh man, am I actually relieved reading this thread. Just took my baby (iMac G5 first generation) in for repairs today, not knowing what was wrong with it. Luckily my serial numbers are in the range, so I'm crossing my fingers that they're going to cover this.
Brief synopsis of what happened, in case it differs from anyone else's
About a month ago, my iMac started to not wake up from sleep mode. Instead of waking up, it would just shut itself off. This continued for about 2 months, with me thinking nothing of it. Then, instead of shutting itself off, the computer would restart when I attempted to put it to sleep.
Then, last night, I was surfing the net and all of a sudden the power just failed. No noise, no "grey screen", we're talking like a millisecond later the screen was black. I treid unplugging the machine and then plugging it back in while simultaneously holding the power button to reset the PSU and still nothing. At that point it was about 1:30 in the morning, so I just went to bed not wanting to deal with it until the next day. By the time I woke up, there was a distinct smell of electrical components burning (in grade 8 shop class we used to hook up resistors to the voltage generator and crank the juice up until they fried when teach wasn't around, so I distinctly remembered the acrid stench :P)
I opened the back up and did the LED check, and #2 wouldn't even blink. So I took it in and they said they'd have to get back to me and that's where I stand now.
The thing that concerns me is that if some of the components fried that there may be possible damage to the motherboard etc. Luckily I'm not too worried about the hard drive because it did still boot up and all. People that have experience with this, what usually happens with files on your HD after a logic board replacement? Are they usually fine?
The other thing that concerns me is that apple has made no effort to contact me, and it will be 2 years after the purchasing date come November 1, 2006. I'm lucky that I caught this now before it was too late.

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?

Advice for faulty logic board (early 2010 MBP)

So my logic board needs replaced.
I went to the Apple store and they told me as it is under warranty that they will replace it for free. Im not sure how its under warranty as its over 4 years old? Although I have heard that this issue is common and Apple are at fault for the logic board issue?
Anyway I get a call a couple of days later to say that as I swapped out my optical drive for an HDD that it has voided my warranty. They now say it is going to cost £416 to fix!
I just want some advice as to what people think I should do really. The laptop cost around £1800 when new but is probably not worth half of that now if it was in working order. Should I suck it up and pay the price? Should I sell the laptop for parts and buy a new model? Should I try another Apple store?
I was also considering swapping the optical drive back in and bringing it to another Apple store but are there records kept of my serial number etc. where they could still tell?
Any advice would be appreciated.

Buy a new computer or fix yours. Apple will provide no support for it since you voided the warranty.

Logic board failure

Hi everyone
a couple of day ago I was using my mac book pro 13, 2.3ghz intel core i5, it was connected to an external monitor thru the thunderbolt port, had an traktor audio 10 sound card on my USB port, and an x1 controller on my USB port 2. there was an electrical variation, and the computer when of, green dim light came on, but could never get it working again. now sent it to the tec people, they initially said nothing was wrong, they found internally traces of burn mark, ran the scan and everything was fine. got back home and the usb port dint work, the thunderbolt did nt work, and now there telling me i have to replace my logic board. can any one tell me what i should do, its working fine, but the ports are failing, one usb is working, but cant seem to recognize my tracktor audio 10, my thunder bolt dont work, one of the usb is dead, and the ethernet is unstable.
