Logic board interchange.......

Will the 12" 1 GHz logic board fit into the 867 MHz casing? I am under the impression that there is a difference in the port layout. Thanks in advance for any help.

Never mind......

Replacing Logic Board

I have an Indigo 350 mHz from Summer 2000 in which the screen will no longer come on. I get a green power button but no chimes. I have looked through the other discussions and have replaced the battery and reset the PMU, all to no avail. I am now under the assumption that I must replace the logic board. My question (at last) is how critical is it that I replace it the exact same logic board (part # and all). I see many varieties available on ebay, including some with the same part number. Is there any reason I couldn't do a slight upgrade, or am I asking for trouble. Thanks.

Brent,
I concour with Henry too many things can generate your problem MotherBoard, Down Converter, or even a fuse.
If you would like to troubleshoot your problem is better that you download Apple service Manual or check this other web site.
Regarding replacing Motherboard, is some how critical. A research in this discussion may help you.
You may find that motherboard and Slot-loading iMac are some how interchangable (I HAVE NOT TRIED YET). Post #1 but, I also remember that there are something about incompatibility between Down converter and mother boards.
I you have not time to experiment a replacement part# for Part # is the easy way to go..
Hope this help,
Mauro

Can logic board be at failure if I can boot the machine?

My 8800GT went kaputt (screen jagged up and crashes during boot under OS X) so I replaced it with GTX285, which only worked for 2 hours and then machine shut down and didn't power up again with 285 in. But I could still power up AND boot Windows with 8800GT, even if the screen is all jagged up. (Mac OS X doesn't boot, it crashes during boot with 8800GT).
I take it to the apple store in France/Lyon and they tell me they think it's the logic board which has failed. They'll order one, and try, and if it works, I pay, if it doesn't I don't pay.
I told them that the logic board couldn't have failed since the machine boots into Windows without any issues, and I can use the machine on Windows. It recognizes both CPU's and all the RAM, I even did a Geekbench test in Windows.
What I suspected was Power Supply but they said Power Supply is fine. But checking power supply is a long procedure, almost takes an entire day to watch and record all the voltage outputs. It's not a simple task, which I highly doubt they did.
Now, my question is, Can a Mac Pro boot into Windows and be usable with a failed logic board? Have you ever heard of such a thing? I could even use that machine in Target Mode from my MBP. 99% a working Target Mode means all the I/O on the machine is working perfectly fine.

Bowker, yes within limits the slot loading logic boards (350 - 500mhz) are reasonably interchangable. The 600 and 700mhz ones don't seem to fit in slower machines, due to a different shaped heat sink on the video chip. Why are you swopping? You will not notice much difference between a 400 and 500mhz, I swopped between a 350 and 500mhz and honestly there's very little difference. Three important things if you do decide to go ahead.
1 make sure that this board works before purchase
2 replace the PRAM battery while you have your iMac in bits
3 if you are going to run OSX, make sure that the new logic board has been flashed with the 4.19 firmware.
hope this helps

IBook G4 1ghz 14" logic board change

I have a 14" iBook with the 1197mhz cpu. The logic board is bad and I have been looking into a replacement. My question is, will the 14" ibook 1.33ghz board work in here? They look identical but I just want to know if anyone has tried this or knows for sure if it would work.
Thanks!

Most people are not, but there are a lot of people who are indeed 'tech savy" and they generally know who they are. There is nothing magic about the construction and assembly of the ibook. It is just a bunch of components assembled in a particular way.
I have had many computers apart and I never wear a grounded wrist strap and have never had one fail. The potential for doing harm is real but it is grossly overstated unless you have a careless approach in your work. There is no need for a strap if you know what you are doing, and that means understanding what potential your body is at, your tools, and the equipment you are working on, and how to keep them all at the same level as they change.
The logic boards in question may very well be interchangeable. For instance, there were three different speeds of the Powerbook 3400 which all had interchangeable mother boards. In fact, they interchanged with the first G3 Powerbook which used an entirely different processor.
If you have competency in these matters (and you know if you do or not) don't let the nay sayers discourage you. The rewards for fixing something yourself far surpass the feelings you get from buying something.
This forum is not really a good place to ask the question about whether a logic board will fit. Rather, try the ibook mailing list. It is made up of people who tend to fix things for themselves.

Are logic boards interchangeable - such as the 3 early 2005 power mac comp

Hello all,
I have another question similar to the one about whether or not different cases can be interchanged.
My "new" question is this:
Are the 3 "early 2005" Power Mac logic boards interchangeable? In other words, could one use a dual 2.0 or 2.3 or 2.7 ghz logic board in any of these models
or is each logic board specific to the speed of the processor? Or can the quad 4 2.5 ghz logic board be substituted into a dual 2.7 ghz case?
When you answer, could you please try to answer in simple terms.
Thanks,
Stacey Bindman

Hi, sorry for the bump. I am looking to get a new logic board for my G5. I've been looking around eBay and some info you said contradicts the descriptions of some items, namely:
http://cgi.ebay.com/APPLE-POWERMAC-G5-820-1760-A-LOGIC-BOARDW0QQitemZ230384643421QQcmdZViewItemQQptZMotherboards?hash=item35a3fead5d&trksid=p3286.c0.m14
and
http://cgi.ebay.com/Apple-G5-DUAL-2-x-Ghz-Logic-Board-661-3585-820-1592-AW0QQitemZ380161839415QQcmdZViewItemQQptZApple_Desktops?hash=item5883695137&trksid=p3286.c0.m14
The 820-1760-A only has 4 ram slots, and by what Steve said, can only be compatible with the 2.0 ghz processors. The second listing has a model number of 820-1592-A, which the seller claims is compatible with 2.0+ ghz processors.
So which one of you is right? I'm looking to replace my June 2004 board which has the same model number as the second listing, but am not sure if that listing is an Early 2005 model or not...

Logic-boards

HI I have a macbook and a macbook pro, the motherboard of my macbook pro has broken and I was wondering if they are interchangable, if not how much is it to replace a macbook pro motherboard/logic board.

Hi Tommy
they're not the same - used replacements likely start $500 + fitting, unless you get lucky.

Possible to swap MDD FW400 for FW800 logic board?

Hello all,
I'd thought I would ask this question because I have been thinking about this. Currently, have a dual 1.25 2003 model(not earlier MDD!) MDD G4 with the 2MB L3 per processor.
I just received today my airport extreme USB netgear device and I must say plugged into the USB 2.0 5-port card I have it is even faster than the Belkin PCI F5D7000 card! But, my question is concerning something else.
FW800 logic board - is it really worth it for me to swap current FW400 board with the FW800 board? 2ndly, can I use my existing MDD case or do I have to find another case? My power supply is a 360w power supply. I am not sure if it is a quieter one or not. The date on my power mac G4 2003 says: copyright June 2003(or was it July?) Apple computer. - Does this entail that the FW800 machines came out the same time as mine did? Again, I don't have the original MDD(867,1gh,1.25), I have the last dual bootable OS 9.2.2 MDD machine from 2003.
Also, is the airport extreme card going to produce faster results that the netgear WG111V2.0 USB device I currently have plugged into my USB 2.0 pci card? One thing I did notice is that I can no longer put my computer into hibernation or deep sleep, since I now have the USB 2.0 netgear wireless device attached.
Can anyone confirm if there is a way around for the sleep/hibernate function to work even with the USB 2.0 device plugged in? I also removed the Belkin wireless PCI card(FD57000). Before the USB 2.0 device, my computer would goto sleep and hibernate normally.
Thanks!

*9.x and Internet*: shouldn't be a problem with Ethernet. Forget which control panels you'll need to play with TCP/IP, Network? So if you want faster Internet with the MDD in 9.x, go with Ethernet -- the regular Airport card will work in 9.x by the way. That's the reason why for faster wireless, I'm going to buy the new Airport Express (with wireless -n), and connect via WDS to my Airport Extreme -- the MDD will connect to the Express via Ethernet which should be fine in both 9.x and OS X.
I did this once before my the original Airport Express (wireless -g) and an old Linksys all-in-one that supported WDS. But the Linksys blew its ethernet ports, so I replaced it with a newer model that doesn't support WDS.
*Copper heatsink* should fit any MDD CPU card, I've tried mine on both a Dual 867 and 1.25GHz cards, although I'm using a Verax cooler on the 1.25GHz Dual. The copper contact plate while narrow (about 1.5 cm) is a long piece, so it would contact both single and dual CPUs. As for the 1.25GHz dual in particular, see here.
Just a tip, use some good thermal compound, like Artic Silver. You'll need to clean off the old compound on your CPUs. I used Articlean (also made by Artic silver), works great. They sell a kit with both cleaner and purifier (preparation compound for the thermal compounds).
*Dual 1.25 2003*. I think the best way may be to check the model number. According to everymac.com, it should be M9145LL/A. I'm sure the info's also on Apple's site somewhere. The last 2003 1.25Ghz have 2MB L3 cache, which is easy enough to see in say System Profiler. If you're seeing 2MB L3, then you know you've got the CPU from the last 2003 model. As for the motherboard, you'd probably have to check the assembly number under the modem to insure a 2003 motherboard, but I don't think that matters as much as the CPU.
The CPU cards from MDDs and G4 XServes are pretty much interchangable --setting aside the issue of 133MHz and 167Mhz front side buses, which could overclock or underclock depending on CPU card & motherboard combination. And reading around there's an incompatibility with certain MDD Dual 1.0GHz on certain motherboards.
You could put an early 1.25GHz dual with only 1MB L3 on a 2003 MDD motherboard; for that matter you could stick a 1.42GHz dual from a FW800 MDD on your 2003 MDD motherboard, which some people have done. I guess if you're seeing Dual 1.25GHz w/1MB L3 advertised as the last 2003 MDDs, then people might not know what they're talking about, or may have replaced the CPU. The 1MB L3 versions cost less.
FW800, indeed if you want it, you can always add a card later. Since the MDDs don't have USB2, for that you'll need a card as I think you've already done. But there's always a worry of eating the slots. While rare, there are some combo USB2/FW800 cards. Problem with a combo cards over separate cards is that there's usually a performance hit on the FW side. A friend of mine has one that suffers from this -- like 7-10MB/sec hit. I recently bought a Siig combo FW800/USB2 and there's not nearly the performance hit; FW800 is only a few ticks less in MB/sec compared to my FW800 only card. In my DA, I didn't see any deep sleep issues with the Siig card, but every Mac is different. I've haven't tested it in a MDD, yet.
I'm working on getting two MDDs working (long story), so I have my hands full. Can't say I love the MDDs yet, but I certainly been bit by the tinkering/upgrading bug. So I'm have fun getting my two MDDs together that are both very close to being ready -- I need to stress test them before moving over my HDs/data, cards, etc.

New MBP logic board and wireless internet does not work anymore

hi there
i had to change the logic board in my only 2 years old MBP15". i purchased a new one and put it in by myself (relatively easy task). i still use the same internal HD as this one still works fine, so all data are the same.
however, the new logic board has obviously a different "identity" from my old one, it came with a sticker which says "ethernet ID 001FF3513E7A" which is different from before. this may be the reason i can still access my wireless network at home, but the self assigned IP address prevents me from connecting to the internet. all settings are as before and it worked always without a problem.
all settings were "automatic" before (using DHCP), and i use exactly the same settings again, but no success. i have to add that i use a new mac mini in the same network with absolutely identical settings (automatic) and this one receives a free IP address from the router (which is only in the last number different from the router's), but the MBP shows a totally different IP address.
i could finally fix it switching to "manual" and adding the same IP address the mini is using and just changed the last number, which has to be different from the time capsule i use as wireless device and the mini. like this everything works just fine.
but why does the mac mini perform everything automatic and the MBP (even with the new ethernet ID - and especially since i connect wireless and not using ethernet) is not able to do so?
i worry if i want to use the internet in any wifi hot spot i may run into troubles...
any idea what the difference between these two machines (with identical settings) is?
thanks and cheers
george

Thank you. It didn't work unfortunately :((
Here are my router's details (Huawei):
Product name HG655b
Device ID 00E0FC-21530307237S0B028701
Hardware version VER.C
Firmware version V100R001C02B018
Batch number RWC3P0.010.29066
Physical address 5C:4C:A9:A5:41:B0
System up time 0 days 0 hours 15 minutes 56 seconds
I don't have Mac filtering enabled.
Now it doesn't even find the wireless network anymore...
My computer and itouch are connected to WAP, but the iphone could not connect to WAP, but only WEP.
Any other ideas?
Thanks a lot!

Has the NVidia GeForce 8600M GT logic board replacement program been extended by a year?

I have heard that the logic board replacement program for MacBooks Pro with the failed NVidia 8600M GT chip has been extended from 3 to 4 years after the date of original purchase. However, a local AASP had no knowledge of such an extension. Is this true? I have a MacBook Pro 17" 2.6GHz that was purchased in 2008.

when you took it in, it had been more than four years since your 2007 machine was originally sold, that's why you got the response you did.
Actually it was within the time frame, it felt like it was just last month, when it was like several months ago.
Just dragged the 15" recently out to see to use it for testing *cough* and low and behold it's worthless now.
The problem I have is I told them at the Genius Bar the video was going, but couldn't prove it as it was very rare it occured.
But they ran their little tests and gave me a load of crap, now it's dead. $2500 down the toilet.
I know what did it, Lion. Lion was the cause, it ran like a fine machine under Snow, fscking Lion, I'm glad I didn't put that POS on my new 17"

IPhone 5S 32GB Logic Board Repair

So several months ago I attempted to repair the cracked screen on my black 32 gb iphone 5S on my own. It did not work out. I ended up breaking the logic board and now the phone is basically unusable. I've been using my iPhone 4S for the past few months and it ***** so bad. I just want my 5S back but now apple won't touch it and no one offers repairs for the logic boards on the 5S that I can find. Anyone know of a solution or someone who offers the service. Because I can't stand the crap battery on the 4S and I miss my 5S I had only had it for like, 2 months.

I know of 2 services that repair logic board damage depending on your issue and your location in the U.S. One is eDigitalNY which is on the east coast and offers their repair services on eBay in addition to their website. They guarantee their repair work. Just ship them the logic board (shipping to and from is included in the repair cost) and they will fix it. If for some reason your board is "toast" and can't be fixed, they will refund your money. The second option on the west coast is The Repair Stop. Like eDNY, all repair work is guaranteed. TRS is a bit pricier but they are the go to guys for water damage repair, an area of repair from which many others shy away.

Problem with Logic Board in a Macbook Pro 15" 2011 in Argentina

Hi I am from Argentina and I am reporting a problem I've had a few weeks ago:
I was working with my computer (MacBook Pro 15 inch Late 2011) and it suddenly stopped working; the screen was frozen. I proceeded to restart it, but it couldn't enter the operative system, showing a gray screen.
Given this huge problem, I took my MacBook Pro to an authorized support centre in my country (Mac Station, 1184 Ayacucho , Buenos Aires - Argentina). The people there told me that the Logic Board was damaged. For this reason they set a budget of 2.440 dollars for the replacement part – plus the installation cost of 120 dollars. They were trying to charge me the equivalent to a new MacBook Pro model MGXC2LL/A purchased in the USA.
On the web it is documented that the 2011 MacBook Pro has recurrent failures on the Logic Board. How can it be that the total cost of repair in my country is five times the cost of repairing it in the United States? I think their official resellers in Argentina are taking advantage of us.
How I can get in touch with Apple support or someone who can give me a reason for that cost? Can I recieve official Apple answer in this comunity?
In advance: I haven't got Apple Care because Official Reseller from Argentina said me that Apple had discontinued in South America.

Thanks muchly will check it out now.

How's your Mid 2010 MacBook Pro doing after changing logic board due to BSoD?

After this very long discussion:
https://discussions.apple.com/message/15665312#15665312
In which a lot of people had BSoD problems after upgrading to Lion, and then have solved the issue by having the logic board replaced, I'd like to ask, specially for those who have done it earlier, a few months ago or so: did you have any problem with your 2010 MacBook Pro 15" since then?
I'd like to know it because, by reading that thread, I have reasons to believe that the problem may arise again after some time.
I had the same issue with my MBP, but I'm still on Snow Leopard. I had the logic board replaced more than once (actually 3 times), and everything is ok since then.
Now I've been pushed to upgrade to Lion so that I can continue using iCloud. So i'd like to know what are my chances of going into that nightmare again.
Any info will be appreciated.

Greetings,
I've never heard of this issue - I have two MBP Mid 2010, and both are running Lion with all updates, and there are no issues of any kind. One of the graphic shops I work with has 15 Mid 2010 MBP, all running Lion, and there are no isues with them.
We use a lot of high end software, but no games, of course, just business and graphics apps. There have been no issues with Mail, Calendars, Addressbooks, etc, except for wanting a few more features, here and there,
which we will get in time.
Bad apps are the usual culprit, when there are problems with Macs, and they are not always easy to locate, so I just reload from scratch, and thet will usualy fix a lot of ills, if the normal troubleshooting tools don't resolve the problem. Fortunately we have had very very few issues with our Macs going back to the late 90s, and earlier - they just work, and work.
Try a reload if you have troubles.
Cheers,
M.

Mid-2010 MacBook Pro 15" 2.8 GHz Logic Board Part Number

Hi all,
I have been searching for a few hours trying to find the part number for the logic board one of my MBPs. I, unfortunately, have the Mid-2010 15" MBP with the bad GPU that results in endless kernel panics. (I also had the first Pentium chip, the pentium 60 with the floating point error in 1995 too). I upgraded the MBP to the 2.8 GHz, core i7 (2 core) processor when I ordered it in 2010.
Anyway, the apple tech guide exploded view does not show the part number for the 2.8 GHz. It only shows the part numbers for the other 3 configurations - 2.4, 2.53 and 2.66. I took the cover and discovered my my EEE code is "QAG".
I have just started trying to figure this issue out (too much time has passed and Apple will charge me to fix). I want to try and find a replacement logic board and do it myself. Does anyone have an idea what my part number is for the logic board? None of the sites I searched have a 2.8 GHz board listed just 2.66.
An alternative question - In my PC building days, some motherboards were compatible with multiple speeds of main processors. My computer model number
MC373LL/A
is the same as the 2.66GHz model. Does the 2.66 GHz logic board support the 2.8 core i7 too? I don't want to screw up and order the wrong part.
OSX Yosemite is installed.
Thanks,
Tony

Mid 2010 MacBook Pro - Logic Board Failure - Advice Needed

Hello all,
I could really use some advice.
I have a MacBook Pro that I bought through the Apple Online Store roughly around September of 2010. A couple of weeks after buying it I had to take it to the Apple Store in London's White City due to a keyboard backlight issue. About a week later I collected the MBP and the following day had to take it back as the technician that worked on it had not tightened the display brackets up leaving it a bit floppy.
Now I have serious issues with it. Recently the MacBook has been suffering from freezing up, booting issues and the display randomly shutting off (going black, no pixelating or anything) to the point the machine has become unusable. 2 days ago I took the MBP along to an appointment at the Genius Bar at London's Regent Street Apple Store, I also took along a copy of an Apple knowledge base article regarding this very issue. The knowledge base suggests that on any OS below Mountain Lion a software update is required, for ML or Mavericks an appointment with a service agent is required. During the appointment the Mac Genius suggested it may be a software issue, they would wipe the system and re-install Mavericks then test the machine, I told him I had done this a few days earlier but I guess they have to follow process. He then went on to suggest the display may be faulty, I told him I had no reason to suspect that was the case and moved the screen forwards and backwards at varying speeds without a glimmer of a flicker. At this point after reading about this issue on various forums prior to the appointment I felt that the guy was trying to imply anything maybe at fault but deliberately steering clear of suggesting the logic board, this is just my gut feeling however and i'm perfectly capable of being wrong but I do not feel I am! Anyhow I then proceeded to demonstrate the issue whilst the machine was on, warmed up and right in front of him. I gently and slightly lifted the front left corner of the machine a little way off of the counter, just enough to obviously flex the logic board by a minuscule amount and immediately the display went into a frenzy of going off and on.
So I left the MBP with them for the guys to do their thing. Today I received the following email:
"We have attempted to repair your machine by erasing all the data off your machine and reinstalling the latest operating system, Mavericks. This has not resolved the issue of the screen going black when in use. The issue has occurred again for a very short and brief few times once the machine had fully turned on and after testing the issue did not appear again.
I'm sure the issue will more likely occur again, to repair the machine we would need to replace a part known as the main logic board. This repair is very expensive and will come roughly to £418.80."
£418.80 GBP, that's pretty much 25% of the original purchase price of the machine new, a Premium 'Pro' labelled machine just 3 years old at that. I cannot possibly afford to pay for the repair. I really despair.
This MBP has done no work hard enough for it to get stressed. It is used for some web surfing, online shopping, email, online flash based games but mostly for my kids homework. It has spent it's entire life on a table in our living room with the exception of it's Genius Bar trips.
I love Apple products, it's why as a family we own so many off them. Too many to list on a public forum as I don't want would be burglars inviting themselves around sometime. This issue has tainted my perception of both Apple and it's products. Not so much because of the fault, machines become faulty. No because it's a premium machine that cost me £2100 new and is little more than a paperweight at present just 3 years down the line. Some part of me if i'm honest was wishing but more than that expecting a company like Apple to say along the lines of "This has happened, it shouldn't have and will be repaired at no charge". There are many people suffering this kind of problem with this model and the existence of the knowledge base article must mean Apple knows it too. Just 3 years, £300 PCs last longer than that i'm sure. It does seem to be a very short lifespan for such a high end machine.
My apologies for droning on but I can neither afford the repair or do without the computer, my son is in his final GCSE year at school and my daughter in her pre GCSE year so a computer is critical for school homework research etc. I just do not know how to move forward, I haven't even picked the machine up yet!
This isn't a stomping Apple, one man crusade. I just need my MacBook fixed.
If anyone has had this problem and had it satisfactory resolved, knows who to speak to that may help resolve the issue please let me know.
Any other advice will be more than welcome.

Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
I know you have a gripe, I get that all too well honestly .

Tiny burn on a functioning logic board causing dark screen!?

Hello everyone!!! Hoping someone can help me because i am totally STUMPED!
I have a 2010 macbook pro and the screen suddenly went dark. The computer works perfecty with an external monitor, so i assumed the backlight was just burnt out.
When i took it to the Apple Authorized Mac Support Store here in Brooklyn, they thought the same thing and kept it to replace the light. HOWEVER, a few days later when they called the said they had replaced the lights but the screeen was still black! So they opened up the computer and saw that there is a tiny burn on the logic board that is preventing my screen from lighting up.
I asked them if they can just fix the tiny burn but they said no, i would have to replace the entire logic board for close to $1000.
Question #1: Does this sound right??? As I said, the computer functions perfectly with an external monitor.
Question #2: If this is correct, is it possible to just fix the little burn instead of replacing the entire logic board? Some time of component repair?
Question #3: if i was able to find some place to fix the tiny burn rather than replace the entire logic board, are the chances high that i would have a problem again sometime in the near future?
I just dont want to go out and have the board replaced for close to $1000 and have the darn thing break a month later. I would be totally screwed. I desperately need this laptop for work!
Any help would be greatly appreciated!!!
Thank you so much!
Tracy

It is "broken" if it does not work when connected to good componets like a good screen.
Based on the phtos and desciption I say it is damaged.
