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?

What can I do to stop Logic from crashing with my plug-ins??

I'm running...
Logic Pro v9.0.0
2Ghz Intel Core 2 Duo iMac
2GB RAM
Native Instruments KOMPLETE 5 plugins (mainly Battery3 and Electrik Piano)
I have no problem with latency in audio recording and never even get crashes when using Logic plug-ins or running a lot of tracks at once.
But when I use the Native Instruments plug-ins and start turning some knobs on their interface, Logic quits without warning.
This isn''t all the time. But it does happen frequently, especially when running multiple plug-in instruments.
I can still get work done if I hit save all the time but it is getting more frustrating as my song grows larger.
Is there any sort of setting in Preferences that would help me with this?
I just ordered another GB of RAM. Do you think that will help at all?
What should I do? The KOMPLETE 5 instruments are too good to go without.
Thanks.

I ran Activity Monitor while opening a few projects in Logic. And it seems that I only have about 560MB of RAM left to play with once the song loads. Before I open Logic I have about 1.5GB of RAM that is free. So yeah, I think this is the problem.
When I get my RAM in the mail, I'll try going plug-in crazy and see what happens. And then I'll post back here with the results for anyone that may be reading this in the future.
But thanks for letting me know about Activity Monitor. I learn something new about my mac everyday. God bless.

24 Inch Intel iMac... may have bad Logic Board

What are my options if the Logic Board is bad? Is this something you can purchase? Dont have an Apple Store anywhere near me.
Thanks!

What are my options if the Logic Board is bad? Is this something you can purchase?
No, at least not from Apple. You'd have to find the logic board from some unauthorized third-party vendor.
Dont have an Apple Store anywhere near me.
You do have an authorized Apple service center in Wichita, Haddock Computer Center, on E. 13th St. N. They can handle the repair for you. There are also places, including an Apple Store, in Tulsa and Oklahoma City which might be an option.

Logic Board Fails- again.

Hi everyone.
I have an iBook G3, purchased in Sept. of '03. The logic board crashed in Dec. of '04, and again in March of '05. Both times, I had the notebook sent in, and apple replaced the logic board free of charge, under the logic board replacement program.
Now, however, it has failed again. And, I'm getting a little fed up. I'm wondering what you think I should do- send it in for a 3rd replacement (which it's still under the 3 yr- policy until Sept), or try to fight for a replacement of the computer altogether. I'm afraid that if I get it replaced, it's just going to crash again outside of the 3 year plan, and then apple won't do anything. Should I attempt to demand a new machine now?
Times like these are soo frustrating. Mac's are great, but when they have problems, it's like the whole thing falls apart and there's never an easy tweak or fix.
Thanks for your opinions...
Melanie Patterson

I was kind of afraid of that. I'm not surprised.
When you get it back, avoid picking it up by the left front corner alone. If you're going to pick it up with one hand (as I usually do), pick it up in the center, under the trackpad.
The theory is that picking it up by the left front corner causes enough flex in the case that it puts pressure on the logic board and causes the solder on the graphics chip to let loose. So, if you can avoid doing that, it may help your iBook last longer.
Have you seen the new MacBooks (just announced yesterday)? Maybe your G3 will last you long enough to save up for one of those little sweet things. I'm looking at them longingly.

Repairing logic board by hand?

My screen has succumbed to the iMac pixelation disease. Has anyone figured out what parts actually fail on the logic board which cause this? I would like to see if I can replace them myself.

Hello and Welcome to Discussions.I really don't think you're going to get anywhere with this. Even if you posses excellent soldering skills you wouldn't have the chips to replace and if you linger on that board a split second too long you've fried it all.
Could you provide more info on what you've tried and exactly was the issue is so we can see if something more realistic could help.
Cheers

Powerbook G4 titanium bad logic board

HELP, my second computer is a powerbook G4 15" and i have been told i have a bad logic board. is it worth replacing or should i put the $500 toward a new one? Also coould a bad logic board cause other problems in the future? what happens to make a bad logic board? what does a logic board do?
thanks for all the info.

Hi Tour Man,
Welcome to Apple Discussions.
Which model TiBook do you have? Especially if it's one of the earlier models (400-667VGA), I would certainly not spend $500 on it, as you would probably not be able to sell the entire machine for that price.
If it's a later model (667DVI-1GHz), consider what you use it for (if you have it fixed, how long is it going to serve your needs?), the capacity of the HD, how much RAM you have, whether there's a wireless card or DVD burner, the condition of the battery, whether USB2 and the many other "updates" a new machine would offer are important to you, etc.
It's not likely that a bad LB would cause other issues.
A LB (same as "motherboard" in PC land), is a circuit board on which most of the essential elements of a PB are soldered (CPU, GPU, RAM slots, etc), so when any one of these has issues, the repair is to replace the entire LB (specialized equipment is needed to work on the micro-circuitry, so it isn't something a repair shop can repair).

Worth installing new logic board?

I've just been to see a Mac Genius because of problems booting my PB (see previous post), and through a process of elimination she said it must be a logic board component problem that's preventing the power from routing properly.
Is it worth the cost of installing a new board? I have a friend who could probably do the labor for his 'friends and family' rate, so it's really just the cost of the board itself--but I have no idea how much they run.
This is a back-up laptop (we have another MacBook Pro at home), but despite its age it functions well for what I need it for, which is mostly word docs and email. It's got a fairly new hard-drive installed about 18 months ago, and a one-year old power adapter cord which is in great shape.
Thanks in advance for any advice!

If the clock battery hasn't been replaced in the last 4 years, that's the first place I'd look. Next I'd look at the internal power supply to find out if the wiring got loose. If neither appears to be at issue, find out for your model what it costs to replace the logic board. These places may be able to help you for less than Apple:

Diffrences between QS logic board Rev1 and Rev2

Hi my Lobo has died on me and i was wonder what the diffrences between the QS logic board Rev1 and Rev2 are
From researching on the net i have found out that there are two types of board numbers for my model
820-1342-B or 820-1276-A
The man number on my board is
820-1342-B
But i can only get hold of the "A" model...will there be performance issues
Thanks guys

There were two distinct versions of the QuickSilver:
http://support.apple.com/specs/powermac/PowerMac_G4_Quicksilver2002.html
http://support.apple.com/specs/powermac/PowerMac_G4Quicksilver.html
As for performance differences there aren't many, but it really depends on what you put on the machine. The newer has faster cache. Also if you are lucky to get a June or July 2002 QuickSilver logicboard (earliest 2002 were January 2002), you'll get added support on the PCI bus for 128 GB or larger hard drives on a single partition. Though there are PCI cards which support that as well.

IBook logic board - Apple service - kinda long, sorry

I am a converted PC user who got my iBook in September 2002 because, frankly, I was tired of dealing with the poor performance, terrible service, and general glitchiness of my old pc's. So a few of my friends encouraged me to try out a Mac. So I did and I fell in love with how it just seemed to work!
I've had my iBook for just over 3 years, and have had a good amount of problems. It occasionally would boot up to the sad face and I'd have to go through the whole process of reinstalling the OS while on the phone with AppleCare. This past summer, I sent the computer back to Apple because it locked up constantly and the hard drive started clicking. After about a month of sending it back and forth, they finally acknowledged that there was a problem with the hard drive (as if the loud clicking wasn't enough) and replaced it.
Ever since then, things have been ok, but glitchy. The screen would freeze, when you opened the notebook up, it would be on a blank screen, etc. Then earlier this week, it started showing lines through the screen, and it would lock up. Upon restart, it would restart with a blank screen. I thought it was a gonner.
So I looked online to try to diagnose my symptoms, and low and behold, I think I know what's wrong. The iBook logic board description on http://www.apple.com/support/ibook/faq/ explained my sympoms exactly. So I spent an hour on the phone with customer service yesterday trying to figure out if they'll fix this. And alas, they said despite the fact that the logic board may have been failing after the July repair and despite that I've just barely exceeded the 3 year limitation for the logic board repair, they will not repair this unless I pay for it. The quote he gave me was almost enough to buy another computer.
So here I am, a guy who came to Apple for a quality product, Apple acknowledges that the logic board they installed in my computer is less than top-quality, but they refuse to replace this inferior component because of an arbitrary 90 day warranty on repairs performed in 90 days and an arbitrary 3 year from purchase date repair on the logic board.
I'm the first one to admit, they don't HAVE to do anything. I just think it's a sad state of affairs when a company that relies so heavily on a fan base, would slap a newly converted fan in the face on his maiden voyage with a Mac. I expected more from this company. If I wanted cheap junk parts in my laptop that would've only lasted 3 years, I would've bought a PC. The PC is cheaper anyway.
Now I sit with a useless shell of a computer at home and try to decide what I want to replace it with. I have to say, I love OS X, I love the simplicity, I love the security, but I'm going to find it very hard to justify it to myself and my wife to buy another Mac. I think this converted PC guy is headed back to a PC where at least you get what you pay for.

Hi, Nick. Welcome to Apple Discussions.
Are you willing to try again? Call Apple again, and this time, ask for Customer Relations. Tell them your story and ask them to make an exception to the three-year rule in your case.
Customer Relations likes Switchers, and they are the ones with the authority to make an exception to the rule.
No guarantees, but they just might do it for you, especially if you plead with them, "Please, please, don't send me back to Windows!"
Usually, I advise people not to threaten to go to Windows, because why should they help you if they think they've lost you as a customer? But, in your case, it's a little different.
Personally, I would have to have about four Macs in a row go belly up before I would look to Windows, and, even then, I might just give up computers all together and rely on pencil and paper if I had to deal with Windows.
Good luck. Let us know how things go.

Logic Board has failed 3 times...2011 MB Pro 15 Inch

So I have recently had a ton of issues with my MacBook and it is really starting to get annoying. I had my logic board replaced in March of this year. The repair cost me around $350 as the warranty was up. The logic board failed again at the end of August. I brought it back in to the apple store and they replaced the logic board again, but for free this time. I was extremely impressed with their customer service, they even replaced my display which had a small crack. Everything worked good as new until last night. Once again the same issues as before, so obviously they logic board has failed for a third time, which is a little ridiculous in my opinion. I will be taking it in to the apple store after work today to see what's going on.
Three logic boards in the span of half a year can't be normal...Is this a sign of some other issue? Is it time to ditch this POS and get a PC? Could it be something I'm doing on my end? I rely heavily on my laptop for work and need something that consistently works. Apple's customer service has been top notch through all of this, however the actual product has not been. I would love to hear other's opinions/experiences with similar issues.
Thanks!

Perhaps - and I mean PERHAPS - you'll be offered a replacement unit this time around: it all depends on how the manager is feeling that day. A number of 2011 models have had three logic board replacements and USUALLY the fourth time around, folks are offered a new replacement unit.
Don't count on it but if it comes down to pleading with a manager, DO IT!
Good luck,

Login keychain not storing iChat password since new Logic board

A few weeks ago I had to take my MacBook Pro in for repair (the graphics chip died). At any rate, they fixed the issue by replacing the logic board. Now, however, it seems to have screwed up my login keychain.
Whenever I open iChat now I'm prompted for my AIM password. Even though I ask for it to be stored and remembered by keychain it is not. I have tried repairing the keychain, creating a new one, deleting/re-installing iChat, and even trying a brand new user account all to no avail.
So what gives? Has the new logic board permanently screwed up some settings on my MBP? Is there anything else I can try?
Thanks

I already re-installed iChat by running the Optional Installs.mpkg from the SL disc. Is this why you were suggesting I use Pacifist or can it repair the code signature you speak of?
no. I wasn't sure if optional installs offers ichat as an option. if it does you can use that instead of pacifists. it should work just as well. but make sure you reapply 10.6.2 combo update afterward.
What about me not being able to edit and save changes to my keychain items. Doesn't this imply a problem with Keychain?
do you mean you have problems with other keychain items beside ichat? on all accounts?
BTW, you marked my post solved. you shouldn't do that until and unless your problem is actually resolved. this tells other posters that your issue is fixed and disinvites further responses.
I dunno, the whole situation is strange. I have Google Notifier installed on my MBP and it was able to save its password to Keychain just fine.
Thanks

IMac Logic Board Issue...

Here is a little history:
Bought an iMac G5 1.8GHz in February of 2005. In October of 2005 I had the power supply and logic board replaced. In August of 2006 I had the logic board replaced again. In July of 2007 I had the logic board replaced AGAIN...
I am once again having issues with what I think is a faulty logic board. I had a "Must Restart" grey pop-up yesterday. Did an SMU reset, then restarted the computer. It worked for 24 hours. This morning it did the same thing. I restarted, but it went to a blue screen and stayed there... I did a SMU reset, and a PRAM reset. Then called Applecare and they hinted I should do a disk repair with the install disk... Tried that. The computer won't boot from the disc when pressing C on startup... just goes to Blue Screen after grey apple screen and freezes.
I tried starting up whilst holding the "Option" button. Both the Macintosh HD and OS X Tiger DVD are found, but once again, it won' boot from either. Just to the Blue Screen and that is it.
I am over 3 months from my logic board replacement time frame... besides, I think the last replacement of it should have taken care of it last July, right? I have opened up the computer, and there are 5 leaking capacitors...
I am right in thinking the Logic Board is fried, right?
What would you suggest doing? Trying to get another logic board for free from Apple, even though I am beyond warranty? I DO NOT want to pay 800-900 bucks for sure. Any other tips or suggestions? I figure I could get a SATA/USB2 enclosure for the HD if I get another mac... not to mention I am a pretty good back-upper...
Thanks!!!

I have a first generation 20" iMac G5; the logic board failed about a year ago and was replaced under the "iMac G5 Repair Extension Program for Video and Power Issues" program at my local Apple store. It failed again last week; I returned to the Apple store and was advised it would not be covered as it has passed the 3 year mark outlined in the program and was offered a 20% discount on purchasing a new iMac (I did not feel this was a reasonable resolution). I contacted AppleCare via telephone regarding the issue as I felt Apple should support a product with a well documented defect. The "Product Specialist" I spoke to stated "my original logic board had been replaced with an updated one" and "the failure of this current logic board is unrelated to the Extension program failure". He then went on to contradict himself and stated "Apple could not / would not continue to support the logic board failures after the 3 year mark". I was offered no resolution; I am a long time Apple supporter, advocate and evangelist who has advised friends, family and colleagues to purchase Apple products. I am now extremely hesitant to do so after this incident. As this is a recurring and well documented issue with this product, I feel Apple should either replace or offer a replacement iMac at a HIGHLY substantial discounted rate to any customers impacted by this product. Hundreds of posts here and at other forums show there are many unhappy customers.

New logic board causing CRASH?

I just got my G5 back from the shop - the logic board crashed, so i got it replaced.
Since getting it back, my machine is completely freezing on me regularly - particularly when I use Mail.
A friend mentioned that this may have to do with the new motherboard having conflicts of some sort.
I am desperate and working on a deadline - can anyone help me!

take it back, all I can say.
sorry to hear about your problems.

Early 2011 MacBook Pro logic board upgrade question

I have an early 2011 MacBook Pro 17'. Will a late 2011 logic board fit in the unibody of an early 2011? My logic board crashed and I'm looking to install a new one myself. I just need to see if I can upgrade mine at all. I want to purchase a logic board with a faster processor and hopefully not as prone to the GPU failure. Any recommendations?

You have the problem discussed in a number of discussions on this forum, most notably here -> https://discussions.apple.com/thread/4766577?tstart=0.
Basically the GPU in the machine was poorly soldered onto the logic board. If you take the machine into an Apple Store, they will recommend a logic board replacement. This, however, will not permanently fix the problem. The only permanent fix is to have the GPU 'reballed' - this will cost about $160 and some services offer up to a year's warranty on their work.
I had the problem back in January and, as I was under AppleCare, had my logic board replaced gratis. Once I'm left with no warranty, I will have the GPU reballed.
Take a look at some of the discussion and see some of the photos which are just like yours. The only remedy is the reball.
Good luck,
Clinton
