MacBook Pro :: Logic Board Need Replacing?
Oct 12, 2010
Was watching a 720p HD movie on a plane. Movie starts to freeze up. I can move the mouse but the rest of the computer is unresponsive. I force shut down by holding the power button.
Upon restart, all seems well, I login but computer quickly becomes unresponsive again. I force shut down again.
Next restart is over 10 minutes. Gets to login screen but can't login.
I boot from install disk and run HD repair. It finds some problems and repairs them. Reboot. Same symptoms.
I decided it is the HD and archive and install. Install fails. I wipe the HD cleaned and reinstall osx.
All seems fine as I go through set up and login in. A few minutes later same unresponsiveness.
So finally I did what I shouldve done awhile ago which is swap my current hd with my old one. I do and the computer runs fine! I'm at my wits end.
Just so everyone knows, the day before all these symptoms started I swapped my stock 2x1gb ram for 2x4gb ram. I originally thought that was the problem but I've had my original ram in since I've been trying to diagnose and it's made no difference.

so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]

I bought a Macbook 32 month ago and my sister's Macbook is 8 month old. I do some RAM eating tasks, and all she does is type, iChat, and research.
I do Photoshop CS4, Keynote, multitasking, and some games.
Well, the problem is, I have Intel GMA 950, and my sister has nVidia 9400m. She has 2GB of RAM and I have 1GB. And I know what you are going to ask me, and yes, these two Macbooks are the SAME MODEL, just bumped up specs.
Ok, story over, and here is list of what you can do. Please answer as informative or short such as 'yes' or 'no'.
1. Will I be able to swap Logic Board and RAM from two Macbooks?
2. Will it be possible to just swap the HDD AND RAM and me and my sister will be able to keep all the same data, and I will be able to work on heavy multitasking and some good games?

i have a macbook pro 13 mid 2010 which has got a liquid damaged board. The price of a new board + labour from apple is too much and the price of a new logic board from eBay is $1000. I am now thinking of replacing the logic board from the older unibody model which costs around $500. Everything looks the same inside but has anyone had any experience or knowledge of this actually working?

I may need a Logic Board replacement and obviously Apple would do it, but what are the steps in replacing it on a Late 2008 Aluminum MacBook?
Also, are there any possible issues/after-effects from replacing the Logic Board?

The guy that works at the apple store said it is better to buy a new mbp than replacing logic board and cpu.
I was wondering what you guys thought about the subject. Is it better to just buy a new model? or wait for the logic board and cpu replacement?

I currently own a 13" 2010 Macbook Pro and finally after almost 2 years I have decided to completely pimp out my machine! The logic board I have at the moment in my machine is a 2.4Ghz Intel core 2 Duo, HOWEVER my aim is to replace it with a 2.66Ghz Intel core 2 duo from the same year. My dad's computer from work (macbook pro 13" 2010) is the same as mine except it has the 2.66Ghz logic board, of course he said he wouldn't mind if I wanted to switch them. Anyway, as I have the resources, I am now wondering if this is possible and if there are any 'side effects' or if I have to backup everything on both computers etc... (I know it's not switching the drive) In short, is it possible to switch the logic boards between the computers, and if so, will there be any problems or effects? I know I could just swap the drive but I have an attachment to my computer and want to keep it?
Info:
MacBook Pro, Mac OS X (10.7.2)

My iMac died a few days ago. I shut it down the previous night, and then in the morning when I went to turn it on, nothing happened. The screen display doesn't turn on, nothing. I opened it up and did the LED tests, and found that the first one would turn on, but none of the others would. The apple site says to take it to a store and have it fixed.
Now, I bought my mac on December 19th, 2004 ( what a day that was). At the time, I didn't think I'd need to buy applecare or anything. So about how much do you guys think it would cost to replace the logic board? And also, how long would it take to have it replaced?

I've recently been having problems with my iMac G5 iSight after downloading iTunes 9. After a series of freeze-ups, i noticed a visual anomaly appear on my screen. Little hash-marks all over the display were present, and playing DVDs or iTunes visualizer would result in a checkerboard pattern. After doing some research, I found out this was a logic board problem, and it was not uncommon for iMac G5s. However, I kept using my computer for a few more months when it then started freezing two minutes after boot up. I figured it was time to open up the computer and take a look. But after spending the 3.5 hours opening the machine, removing all of the cables and screws, I couldn't find any visible damage on the board. No swollen capacitors like everyone was complaining about. The only strange thing I saw was some discoloration on a few circuits near the USB and Firewire outlets.
I've decided to replace the logic board myself for around $370, and I was wondering about a few things.
1. Would the new logic board come with a processor, or would I need to pry it off of my old one, and re-attach it?
2. Would I need to go through a lot of re-programing and software issues if I replaced my logic board, or would it just start running right off the bat after replacing it?
3. Is this operation worth it? Because I have come to like my iMac after 5 years of use, and I would like to know if fixing it would give me a decent amount of usage before I would simply need to replace it

I was given a free G3 Pismo Powerbook. DOA and traced to dead internal battery. Successfully replaced and the unit is now alive except I have determined the video chip is toast. Everything works except display to all output types is shot - bad colour, vertical lines, huge cursor etc.
Lots of logic boards available on ebay for about $30. This would make a decent starter computer for my young boys.
I'm looking for good instructions to replace the board.
SPECS
Pismo Bronze Keyboard
G3, 400 Mhz
512 MB ram
10 GB drive
DVD ROM optical drive
2 USB + 2 firewire 400 + S video + RGB

I have an old iBook G4 with a dead logic board, everything works fine for about 10-15 minutes, then the display stops responding. The hard drive continues to spin, processor still chugs, etc. I'm going to leave it running iTunes in a few minutes and when it freezes, hit the space bar to see if the actual machine still responds. (In which case I would be sure that it's the video card, or some cable in that area.)
My question: I'm looking on eBay for replacement logic boards, and I'm wondering how specific/universal they are. Obviously, it needs to come from a 14" iBook, but does it matter what processor speed? Eg. Will a board from a 1.2GHz iBook work? I have the iFixIt guide, and I'm not too worried about wrecking the thing, so it's just a matter of making sure I get the right part. (How about this one: Linkety ?)

I'm somewhat new to the forums, and found a really good deal for a brand new macbook air (rev.1). I'd like to know if it is possible to replace the logic board in my macbook air with a newer, nvidia-gfx based logic board. As in, will it fit, does the same power supply run it, same peripherals (airport, keyboard, etc) work/interface with it, etc?

Anyway... I was planning on getting my hard drive replaced because it was making that weird noise I talked about and I still am... but. Something else happened to. My friends dog chewed my power cord (just a few bite marks) and it was enough to make the green like really dim so we unplugged it. Instead of trying to fix the cord... we just got a new one but the computer wont turn on!
The light does not turn red green or orange on the plug but the battery light blinks when I unplug the chord (the battery is dead.. all drained i mean).
Me and my mom took the computer to a store that does warranty repairs on both Macintoshes and Windows computers and they said they would replace whatever for free. Like the harddrive maybe the battery if that is what is wrong and the logic board. But well... we kind of never told them my friends dog ate my first power cord >>
I wanted to. but my mom and my friend said they wont replace it for free if we told. I sure hope there is no way they can find out of the 1000 for a new logic board is true. We dont even have that kind of money right now!
But do you think the couple seconds of not enough power from the chewed cord might have shorted out my psu or something?
Im just curious. I know my friend has a friend that took his laptop in for a similar problem... yesterday or the day before.

Some of you probably will remember my post a week ago, saying that my MBP DVD drive killed my OSX Installation DVD. here is the conclusion of it, I took it authorised service center here in North Thailand. Waited for a week they sad they will change DVD drive and today it finally arrived. Around 11am they called me and said dude, we changed the drive the problem is still there cant install system. Your "Logic Board' is screwed, you have to wait at least 1 week for a new one.
Now what is logic board? Is that main board? Is it possible for computer to still work with a broken mainboard? I mean I didnt damage it, I had kernell panic and tried to re-install OSX so how could that killed my MPB? I still could boot into disk utility and format the drive was just unable to copy files.To be honest my MBP is 3 months old, i took a good care of it. And I'm very very very dissapointed in apple computers now, expensive and damn un-reliable.

I have an A1260 that looks like it's undergoing the problems repaired by this program: [URL] However, I've had this thing apart, replaced the hard drive with an SSD, the optical drive bracket is very bent from when I replaced the optical drive, my display bezel is cracked in two places and held up with duct tape, and it generally looks like hell. Will they still repair the logic board despite all the other, ahem, modifications? I could probably put the original parts back in, but despite that it will be obvious I've taken it apart. It is and was out of warranty when I performed these. Should I take it to a retail store or just call Apple and ship it to them?

My computer recently, today, got a problem where the monitor no longer works, and an external monitor doesn't work. Thought it was maybe this can't get out of sleep problem, but it's not.
A shut down and restart, battery removal, connect a another monitor does not do anything. It seems to work fine otherwise.
Took it in and they said the entire logic board had to be replaced, and would be $1,300. owwww.
Is this reasonable? Anyone have a cheaper way to go about this? This is a 2.4 MacBook Pro. Another option, I would hate to do without my computer for a length of time, but $1,300 is money I really don't have now.
I see in the Buyer's Guide another incarnation of the MacBook Pro is coming. Does that mean the price of my logic board would drop soon?

I have a Rev. A 1.83ghz MacBook which my partner uses. In the last six months we have had an increasing number of problems with it. First, there were the intermittent sleep problems: delay going to sleep, failing to wake. Then it killed three batteries consecutively before Apple replaced the sleep switch and power connector unit (thank heavens for AppleCare). That was back in July. Now the same problem has recurred: the battery is dead and fails to accept charge. Got a call from Apple yesterday to say that they've switched out the logic board and that the item is ready to collect.
We have eight months left on the AppleCare and what I want to know is:
1) What exactly can we expect from a logic board replacement? Do Apple really have a stockpile of 1.83ghz logic board's floating around in case someone needs a replacement or is there any chance of a processor upgrade with this repair?.............

I aquired a MacBook from a good friend of mine who spilled some kind of liquid on this MacBook. It will not power on. I opened up the machine, and I dont see any kind of residue or any rusting, nothing, it looks immaculate. My question is, could it be the keyboard that short circuited? What are my options? Can I manually test the logic board, or cpu?

My Early 2008 MacBook Pro 15" has a logic board problem. I took it to the Apple Store today and they said they would have to repair it but it would cost me $300 as the one year warranty coverage was over.
$300 seemed like a lot to me because I could get a new Macbook for $999 + Student Discount. However it wouldn't be the same configuration obviously.
My question is whether I should spend the extra cash and fix the old computer or should I get a new one instead?And if I get a new MacBook should I go for the Macbook Pros? I was doubtful about them because they are due to be upgraded

I bought a Macbook Pro about 2 years ago, and I got a call from the Apple service center here in Singapore that my beloved Macbook Pro has a dead logic board! How do logic boards die so early!? It's only been 2 years!? I have numerous other Windows PCs, all of which are much older and work fine. Now I need to buy a new Macbook Pro, but i'm not exactly rich... The refresh should be coming around soon, but finances are still a problem. Can I sell it for some cash? (I've tried numerous sites, all offering around $230 for it, but they only receive from the US.) They say that i'll have to pay around $1200 to get the Logic board fixed, can I get it done cheaper?
What now?

My MBP recently had its logic board replaced after it wouldn't power up. Now, seemingly every piece of software that I own needs me to input a serial # to re-register, which is a problem because some won't let me re-register with a serlai that has already been used, and I am missing others....
I think the problem is that the new logic board has a new MAC Address, however I am not sure, and even if that is the problem, I have no idea if/how I can fix the problem.

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.

Last week my friend gave me their macbook for free and told me it had a fried logic board. I took it just because I wanted the learning experience. I'm a freshmen learning engineering, so if soldering/de-soldering is needed I should be fine. I'm wondering how to figure out what is wrong with the logic board, ie. if it got water damage because I was thinking maybe I could try to get replacement components for the logic board. Also it came with a 60gb hard drive, but I was wondering if I could upgrade that. I know I need a 2.5 sata drive, but I was wondering if iIhad to get the hard drive from apple or if I could just go on newegg and buy any hard drive that has 2.5" sata connection.

I have the Black Macbook 13" (from mid 2007). Model A1181. I think it was the 2.16Ghz, 160GB. OSX 10.4. I need help finding what Logic boards work with my Mac. Mine is broken and I need to replace. I will be looking at used or at least ones on ebay to minimize the cost. From the research that I have done. It looks like I can used any of the following:
661-5033 2.4GHz
661-4397 2.16GHz Black
661-4220 2.0 GHz black
*update* Upon further review I believe that I have found the Logic Board number. On the board itself it lists 820-1889-A? Sound correct. I do get hits when I google it. I guess my question is what is interchangeable with this?

I just received my MBP back from AppleCare. Its about 1 year, 3 months old. The display died, and they replaced part# 605-1211. It states on the Service Details: Parts Used: 605-1211 SCV, PCBA, MLB, 2.2GHZ I take it MLB stands for Main Logic Board? What does SCV and PCBA mean? Also, the repair center scratched the bottom of my MBP.

My Early 08's 8600 failed recently (was still working but I got like 10fps on games and it failed the test) so I had it replaced at a few apple stores (an ordeal and frustration in and of itself). Anyways I was wondering if I need to do anything since the logic board has been replaced. Is a format necessary (for optimization and speed and for compatibility)? When I turned on my computer it gave me a warning about my clock being set to March 20, 2000 and a Y2K compatibility error. Should I be worried? All in all everything seems to be OK - unfortunately since my MAC addy changed I can't access Time Machine backups anymore and have to start a new backup

If I got a first Gen 17" MBP, could I replace the logic board with the last gen (non unibody) logic board?Was the casing of the "classic" MBP unchanged from the first gen to the last generation?

A friend donated a Mid 2008 (Aluminum, 2.0ghz, 2gb, 160GB, no FW) Macbook that came out on the bad end of an encounter with a metal pipe. The screen was ripped off at the hinges. I got the bottom. The HD still booted when popped into another macbook. The battery is warped/bent. The Superdrive is bent. Ram appears fine. Logic board appears fine. Case is bent and touchpad is broken.
what to do with the logic board? It appears undamaged, but... All of the connections to it were still secure.
FWIW-That is a really tough case.

my machine was working fine all day. I installed a yep(the PDF management app) trial and the app locked up so I tried to quit the app. It removed itself from the dock but wouldn't disappear from the desktop. I tried to do a reboot but it got stuck so I held down the power button. I then tried to reboot and it kinda got stuck in some kind of loop and I had to unplug some peripherals and it eventually shutdown. But now it won't boot. I press the power button and it just shuts down. I tried resetting the PRAM and the SMC and neither worked. I had replaced the ram a long time ago (January of this year) and thinking maybe it was the RAM I swapped back in the old Apple RAM with the same result. I can hear the CD drive spin but I cannot I hold it down and the indicator light flashes but after a few seconds the machine shuts off.
With my battery being full I am convinced that either the logic board is dead or the hard drive crashed. I do have AppleCare and I do have an appointment tomorrow but my question is assuming the worst and the logic board is dead, is this covered under AppleCare?
