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.

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.

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 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.

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.

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.

Where can I purchase a Logic Board for a 24" Apple Cinema Display?

My 24" Cinema Display started to flicker and black out shortly after I purchased my most recent MacBook Pro. Apple felt that the issue was the MacBook Pro so they replaced it. The problem continued so they suggested I take the Cinema Display to the Genius Bar. The display was out of warranty and the Apple Genius felt the issue was a bad display even after I told him I smelt silicon burning just before it went out completely. He said that he could "depot" the unit and have it repaired for ~$600. Due to the high cost of repair, I chose to purchase a new Thunderbolt Display instead. Recently, I opened the old Cinema Display and found that the Logic Board is fried. I have ordered a new board from 2 different Web retailers. Both accepted the purchase as "in stock" but then stated they could not get the board from Apple. Where can I purchase the Logic Board for a 24" Apple Cinema Display?
Many thanks!

I was very interested to read this document. I think there is a problem with the Cinema Display and that it is frying the computer.
My husband bought each of us a macbook pro. His was hooked up to the cinema display. After about a year, his MBP started to suffer intermittent failures where it would suddenly shut off and have to be hard rebooted. After 2 years, the power or logic board on his MBP completely failed. He bought a new MBP and a Thunderbolt display, and I inherited his Cinema Display for use with my original MBP.
After one month of use with the cinema display, my MBP started to have the same problems. It has to be hard rebooted almost every time I disconnect or reconnect with the cinema display. I went to the Genius bar, and they confirmed that my MBP logic board needs to be replaced; I'm just holding out until spring break to take it back in, as they say it may take a week. Fortunately, I have AppleCare for my MBP.
Our cinema display is 3-4 years old, but it looks like, even though it appears to be working, I should probably get rid of it. I can't keep frying computers!
I'm posting this because I'm wondering how many others are experiencing this problem.

How much does a logic board cost?

So apparently my logic board needs to be replaced. I have the apple protection care package, but was told that if I have any liquid spilt on my logic board that I would have to paid to get it fixed. I was just wondering how much one cost, and if my laptop has a blue tint on it would the damage have came from a drink being spilt on it? I read somewhere it tints the computer blue if the computer gets too hot.

Usually if you have to pay for a new logicboard, you might as well buy a new machine because basically the whole computer is the logicboard.
I've done some thinking about if it's worth it or not to get your machine fixed and have come ot this sort of rough forumla.
A Mac has a life expectancy of about 4 years
One needs to determine where along their life expancy their machine is.
Then divide the investment into the machine, including the cost of new software that won't work on the new OS, by the 4 years, then from that determine if it's worth it to spend the money to get the remaining life out of it or to sell it once fixed and come out ahead.
If a machine is just out of the 1 year warranty, no AppleCare, costs $4000 originally, then it might be cost feasible to pay another $700 to get the $3000 due on it. Sell it used for $3500 say and the burn is only $200 (4700-3500 - one year use $1000 = $200)
Usually third party software a mere year old the developer won't have a paid upgrade, but then again with Appel issuing new OS X versions left and right they may, depending upon how much you pay for third party software and what the upgrade price is also is a factor..

What is it with Macbook Pro Logic Board?

I bought my 17" Macbook Pro about 4 years ago and while sitting idle for about ten minutes it the screen went completely blank. After many reboots to a black screen with no chimes I realised something could be very wrong. On bringing it to an apple dealer in Dublin I hope that this might be the nVidia issue and I'll get it fixed for free. Unfortunately I got a phone call today to say the logic board needs to be replaced and the issue is nothing to do with nVidia. This will cost €1,350 ex.VAT to fix. I cannot believe that a laptop from Apple that costs €2,500 can only last 4 years. I've noticed this laptop would get quite hot sometimes during usage, I want my laptop back as its something I use alot but its alot of money. If I was to fork that sort of money on another Macbook am I likely to run into this issue again? Possibly. I've read alot of forums with people running into similar problems. I do like Apple products and considered them a producer of good quality products but after discussing this with a number of people I'm starting to see alot of flaws. I hope this issue is fixed in future products.

I have this same problem with my 17" MBP - Early 2008.
I'm writing from Brazil, so I took my computer to Apple Brazil, they don't want to change the logic board, because they are saying that my computer doesn't show some kind of code needed to send to Apple US to replace the part.
Does anyone know how I can contact Apple U.S. to make this claim?
Sincerely, Alexandre de Carvalho

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?

Logic board delay (shortage?)

Started experiencing some weirdness and, when I began getting a string of kernel panics, I took my Rev. A 20" iMac to the Apple Store. Sure enough, the main logic board needs to be replaced. The Genius told me it should be ready in a day or so which has grown into a week and talk of "several more days."
Somebody please tell me that s/he recently had their Rev. A's MLB replaced and it only took a week for them to get the part in. . . .
I fear I'm going through Mac withdrawl.

My Rev A problem was it would not boot. Fix was a new logic card and a power supply replacement. This took about 11 days through the Apple Genius counter. When I got the machine back the builtin speakers didn't work. It was a faulty logic board that had been installed. They put me on a priority repair action and I got the computer back the next day.
No more problems since. I shut the computer down every night except once a week on Friday so it can do its Script Maint thing. I never put it to sheep. Always had problems with sleep both with this computer and the Dell PC I had before. I've programmed it to shut off the display after twenty minutes of non use but keep the hard drive running. The wireless mouse (Kensington Pilot) and wireless keyboard are always recognized immediately with this process.

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.

Locking bar for keyboard ribbon on ABook 1.33GHz logic board broken

HELP! I can't afford £400.00 for a new logic board...
Just changing the hard drive. Very careful, but locking bar for keyboard ribbon destroyed.
Anyone know what to use as a replacement/wedge - the keyboard ribbon is a "zero insertion force" item; Apple says "new logic board needed!"

if you have an ibook (I cannot tell for sure from your post), the ribbon cable can be wedged into its slot using a strip of material cut from a credit card type of plastic (here in the US we all get "fake" credit cards in the mail that I keep just for such projects - they also make good squeegees or soft scrapers).
I just cut with a good scissors, and usually try to shape it like a very wide, or fat "T" so that the bottom just fits into the cable slot, and the "T" crossbar protrudes a bit on either side outside of the top, for easy grasping, if you need to remove it. The fit of the plastic bit should be snug, but does not need to be too tight, as the ribbon is also held in place somewhat by the ram cover.
If you have a powerbook, that's another matter entirely. If the socket is broken from the logicboard, I have heard that the socket can be re-affixed to the logic board by a good electronics repair service. If the socket is broken from the cable, then a replacement keyboard would do the trick.
good luck,
Ray
