Concerned about the logic board

I have found out recently that iBooks tend to have bad logic boards. My works fine for now, but I am curious what can I do to make sure that it stays that way?
Thanks.

The best (and, really, only) advice is to never pick it up by the left front corner alone. If you pick it up with your left hand (as I often do mine), be sure to grab it in the center under the trackpad instead of by that left front corner (and, unrelated to the logic board, never pick it up by the open display, either).

Question about the logic board and video

Hi, i own a macbook pro 17 in. @ 2.4 ghz, and have the nvida 8600 gt card. I'm pretty sure that the card has failed since no video has shown up during start up 2 weeks ago (i asked a friend of mine, and he had the same problem with a macbook pro 15 in., he was pretty positive on a card failure). I brought it to the local genius bar, and they fixed some firmware or whatnot, and it worked fine for a week. A week later, the same problem of no video showed up during start up.
My question is if this is a video card issue, is it possible that the logic board could have been damaged from the faulty video card? The tech. told me that it might be the board, and im afraid of paying the hefty repair fee, although i personally feel that the card is all to blame.

Here is the article on the NVIDIA 8600 chip:
http://support.apple.com/kb/TS2377
Note that Apple will do the repair free of charge if the chip fails within the first two years of ownership. The repair will be to replace the logic board, as Apple does not work on boards at the component level. Your machine should be new enough to qualify for the free repair.
Good luck!

After replacing the logic board in my Macbook Pro it will no longer connect to the App Store.

I recently had to replace the logic board in my early 11 Macbook Pro (first gen i7). With the release of Yosemite just a few weeks away I am trying to update from Snow Leopard 10.6.8 to Mavericks. I'm afraid if I don't after this update it will become much harder. I always lived by the rule if it ain't broke and for a long time Snow Leopard worked very well for what I needed to do. All my software is current and there are no updates pending. All my Keychain Access System Roots Certificates are good and I have no problems getting into iTunes. I thought it might be something on Apples end but after 36 hours it's still the same problem. When I try to open the App Store I get this:
Any ideas. I don't use the App Store that much but until this I had never had this problem before.
Thanks for the help.

I've got a mac pro problem with the starting up, but also a red light on the logic board solidly on. Its not among the diagnostic led. It's located near the BT adapter and the front fans. Also the fans run loud also. any solutions?

Hi
I've got a mac pro late 2006, and i am having problem with it for quite a while now. the problem i am facing is the start up process, and the red light on the logic board. Earlier I've got the two led on the diagnostic leds 5 and 6 turned on without the diagnostic button being pressed, and i think those are related to the processors overtemp. I've managed to solve that by, removing the processors and re applying the thermal compound on the heatsink. what i have left now with is the red light on the logic board at the time i plugged in the power. At the same time when this light come on, the power indicator at the front panel come on as well. i am not sure what is this light relates to. We've replace the power supply too, and gone through the SMC reset but seems no help.
Any idea on the problem? I am desperate about it, and i will be greatful if anyone can help..
thanks and hope for your best solutions

I can't help directly with your problem but you might check here http://tim.id.au/laptops/apple/macpro/ for a service manual which could answer your question.

The logic board of my macbkpro 10.6.8 (OS ML) has died. I want t migrate info to another McbkPro (OS Snow Leopard) but is asking me to update to same OS. Can I update the latter to Mavericks and migrate the info from Mountain lion? thanks

Hi i took my macbook pro to an apple store because it would not start correctly. The veredict was that the logic board was dead. As this is a very expensive item to replace, I have decided I will buy a new one but I am currently overseas, and will wait a couple of months when I get back home. This is a macbookpro 15 inch early 2011, running on Mountain Lion OS. I have another macbook pro 13inch running on snow leopard. At the store we tried to migrate the info using an ethernet cable (using the "T" command on startup) but the system asked for an update of the OS. The guy at the store told me I had to update the OS so that the two macs would be on the same OS - mountain Lion. As the newest (and free) OS is Mavericks, I wonder wheather I coud update the 13 inch mac to mavericks and perform the migration. The guy at the store was explicit to say that if the OS were different it would not work. But reading on the apple website it seems that mavericks support this kind of migration altough is not explicit about it. Can you please help?
thanks

Hi BobRz,
As this is a new issue for me, I believe I had the incorrect approach, maybe you can help me. What I want to do is recover a few files in my desktop, and some information i had on the iCal application and the Mail application as well.As I do not want to do a full migration into this computer (which is not mine) I believe that starting the damaged MBP in Target mode should allow me to search and cop the files I need. But:
1. Can I open the Ical and mail apps to look for the info I need while reading it as an external HD ?
2. Do the target machine (my friends) still need to be updated to ML o Mavs so that it recognizes my MBP as an external drive if starting it in Target mode ? (no migration assistant)
Thanks.

Is there anything I can possibly do about these logic boards?

Ok, I have 4 broken 4th Generation iPods. Two of them are white 20GB models, one is a white 40GB model, and one is a U2 Special Edition 20GB model. All of them have broken logic boards. Every month or so I give them another go to see if I can get any of them working. But, like usual, I tried today and had no luck.
EDIT: Let me specify, these are all monochrome 4th generation models.
The difference here (as opposed to previous attempts) is that now I have a working monochrome 4G (meaning a perfect functioning logic board) that I purchased since my last attempt at fixing these (meaning I now have 1 working iPod but still the 4 broken ones). I was able to restore one of my spare hard drives (20GB MK2006GAL model) with firmware version 3.1.1 using this working iPod. I was even able to add songs, and after disconnecting, play them in the working iPod. Not to mention, the hard drive sounds like it is running beautifully.
So, I thought, "maybe if I plug a 4th gen formatted, working hard drive with the latest 4th gen firmware into one of these corrupted iPods, they'll at least play the music, even if they won't connect to the PC". Wrong. I still get the old routine of Apple logo, folder icon, "Do not disconnect" for about 5 seconds until it resets itself to the Apple logo, a sad face, and finally a low battery sign (regardless of how charged the battery is) in that exact order. This occurs with 3 of the logic boards. The other logic board, which was originally in the U2 iPod, is able to boot up, and choose a language, but the logic board is broken in that the battery is undetected (no charging, and as soon as you unplug it, poof, its gone). I've tried several batteries that I know work; I am 100% positive it is a logic board issue.
I've tried diagnostic mode on each and every iPod. On the working 4th gen (with functioning logic board), they pass HDD R/W and HDD SCAN. But they never complete on any other iPod; even after an hour, they've done nothing, and act like they have frozen. I've run the 5-in-1 test on each of these, and they all complete fine.
So... I guess it all comes down to corrupted logic boards prevent the iPod from properly booting, connecting, and completing diagnostic tests. Is there ANYTHING I can do to rewrite or fix these files? Would connecting to a Mac help at all? (I ask because there is no Mac available to me, not even at a local computer store, but if you guys think it would help, I would go out of my way to the Apple store about 1 hour away). I know Mac's use different formats for the hardware, but I thought this was all hard drive related. Thanks for any help/recommendations/etc.
Oh, one last note, about that logic board that is able to boot but can't detect the battery: It actually can tell if theres a battery there, but it just doesn't... work. Like, if I have a completely dead battery installed, and I try to plug it in, I get the battery with exclamation point icon. If I plug it in with a battery 50% charged, it will boot and the battery icon will show that is it 50% charged, but it won't charge it, and it still turns off it its disconnected. Any help with this would be great as well.

I tried running the HP tool today, to see if that would help, but it to was unable to detect my iPod.
I should also point out that Windows can not detect my iPod either (and thus it has no drive assigned to it).

Hi - my 2011 Mac Pro no longer recognizes devices in the usb ports, I've been told it's the logic board. is there a way I can connect the iomega external hard drive to it through the firewire or thunderbolt ports?

Ok, fair enough. But since Job's death - Apple's control on leaks has been terrible. I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones. Because of the vast ammount of leaks. With the iPad mini leaks, it's 99% sure to come out next week.
Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
Amd by "others" I meant other people on iPads - not other devices/manufacturers. It's possible to do so, I just want to know how. I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
No, USB is not the future, you missed the memo about cloud and wireless computing?

After having the logic board replaced, Time Machine will no longer backup my computer to the same backup files as before.

After having the logic board replaced due to bad NVidia chip, my Time Machine will no longer backup my computer to the current backup. Is there a way to reset something to get Time Machine to continue to use the same backup files as before for this laptop?

As far as TM is concerned you have a new computer, so it will make a new backup. If you don't have the space for both backups then erase your backup drive before backing up the computer.

Is there a way of testing the logic board via Terminal?

About 5 days ago, my mac book pro experienced the gray screen flashing folder scenario, telling me that it can't find the OS.
I opened in Internet Recovery mode, and when opening disk utility to check my hard drive, the hard drive didn't show.
After a breif call to apple support, it looked like my hard drive was kapput, so I bought another hard drive (something I've wanted to upgrade for a while anyway).
The new hard drive is a seagate momentus xt 750GB, and fairly sure it's compatible as I watched a youtube vid showing me how to replace the hard drive with the very same drive.
The disk utility cannot find this hard drive either, which means it could be a number of things, the worst being an issue with the logic board..
I cannot open in apple diagnostic mode, but I can access terminal without an OS, can I check the logic board, or anything else that could be causing the problem from there?
I'm trying to find out as much as I can about the problem before I have to pay to get it diagnosed.. hopefully it just needs a replacement SATA cable!
Thanks all,
Joe

Did you format the new drive? This can be done with the Internet Recovery Mode. Try booting holding the command option R keys to get to Disk Utility.

You can run the Apple Hardware Test / Apple Diagnostics:
may not be aware is that Apple dumped AHT this past June. New Macs, introduced in June 2013 or later, no longer include the software. Instead, they have an entirely new diagnostic application called, appropriately enough, Apple Diagnostics. You access Diagnostics exactly the same way as you do AHT: Hold down the D key at startup.
http://support.apple.com/kb/HT5781
New MacBooks can access HardWareTest by rebooting holding the D key, no disk required.
http://support.apple.com/kb/ht1509
or older machines Boot off your Install Disk while holding down the D key, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
If any error codes are generated, post that code back here for interpretation.

Replacing the Logic Board on an iMac G4 (flat panel)

Hi all
A friend of mine has a G4 Flat Panel iMac, and apparently, though I've not seen it for myself yet, her Logic Board died on her. She has since bought an iMac G5. But I've been trying to find where one can get a replacement logic board from, that isn't going to break the bank. I've found nothing so far. Are these available anywhere? And will they be so expensive as to make it not worth the bother? And of course I have not found any technical data about how you open and replace components in one of these iMacs. Apple don't post them since they are supposed to be tampered with only by Apple certified technicians.
Thanks.

Hello,
Apple doesn't typically make their repair components available to the end-user. So, it's a bit harder to find a replacement logic-board for one of their computers.
The service centers can get them, but it's not going to be cheap.
Typically, you can expect to pay $500 to $800 for a replacement logic-board from Apple.
And, the service center is only going to sell it to you if you let them install it.
But, you can sometimes find places that sell them.
This place used to sell lots of Apple logic-boards, case parts, brackets, keyboards, etc. But, they stopped for some reason. But, you might call and see if they have what you need in a warehouse somewhere:
http://cgnusa.com/scripts/default.asp
And, this place does sell some parts for the Do-It-Youself person. But, they typically require you to send in your system for a new logic-board. But, you might be able to get a price from them:
http://www.dttservice.com/index.html
In all honesty, if you are looking for a part you can install yourself, and don't want to pay $500 or more, then you are probably better-off trying to find a used part.
If you can find one who's screen died, but the logic-board is still good on, then you may be able to work out a deal. I hate to recommend them, but e-bay is probably your best chance for a used replacement logic-board. Just don't pay too much.
Whatever route you / they choose, keep in-mind the price of a low-end Mac Mini. Don't spend more to repair an old system than you would spend to buy a current low-end system.
I hope this helps.

Changing the logic board

will I lose my apps in my macbook pro if I change the logic board? For example, I have Logic Pro 8 on my macbook pro. My mac didn't turn on anymore, I went to the Apple store and they told me that I need to change the logic board. If I get the logic board fix, or replaced, will I lose my apps (Logic Pro 8) or will the app still be on there? Please respond because I don't want to lose my projects and the software.
Thanks

Not off topic ... this is *YOUR* post ...
To start, you can sell your old one for the parts that still work (SuperDrive, display, ...). Gives you some money back on a new one.
And PLEASE do not read my following statements as "just pay to fix it" ... I am just stating facts and I for one would probably buy new and sell old for parts
Second ... *most* new units come with Lion, and due to the firmware (PCs have BIOS on EPROMs, Machas "EFI Firmware), getting anthing less than Lion to run is tricky (just look up the number of existing posts on this subject). Some have successfully pulled it off, but it all sounds complicated and I like haing an SL-initial unit.
But do not despair ... some people have hoarded stocks of MBP that can easily run SL because they actually came initally with SL so gray install disks come free. If you start a post asking who knows these vendors, you should get an answer.
Also ... with apologies if you did not know this (as if you had no read anythingthing else I wrote) ...
Lion does not support PPC software anymore because Rosetta is not supported. Could be higher software replacement costs if you do not intensely look for one of the few SL-initial MBP.
If you want to and want to avoid Lion (I have no valid opinion on why you should ... just saying if you want to) then start a thread on "Who knows the venors of existing pre-Lion MBP?".
I only mention the Lion issue because even if you put your old HD into an external enclosure, Lion-ready systems may not boot off that old system with applications you already have installed, and you wold be reloading all apps anyway.
I will stop so you can catch up, and ask more.
Or just jump straight to my recommended post and ask your question about saving old HD and SL-ready MBPs.

What is the little golden coloured metal tab that sticks out the side of the logic board?

Hi,
On the logic board of a 3g and 3gs (i am not sure about the other models) there is a golden coloured tab that sticks out and when the board is in the housing it makes contact with the chrome bezel.
I was wondering what the job of this little part is and what the implications would be if it did not do its job properly.
Thanks

Just be sure no extra parts are left over when you re-assemble it..... as KT said this question goes way, way beyond any guidance than can be offered at this location.

(HELP) Dead MacBook Pro.. possibly something to do with the logic board.

I had been noticing my MacBook Pro's performance degrading lately.. for example whenever I dragged a file into a folder it would lag for 5-6 seconds and then copy over. It started to bug me so I guessed that maybe a reinstall would fix the problem. After reinstalling and rebooting, I got no video on the display.. keyboard wouldn't work.. only things that happened was the disc drive made a sound, light came on the font and could hear the HDD spinning a little.
I then took it to the Apple store as thats what Apple told me to do on the phone. So we took the loverly 3 hour drive(there and back) to the closest Apple store just to have the man take it out the back for 2-3 minutes and then come back to say "It's possibly the logic board that is dead".
I am out of warranty by 2-3 months and so he told me I would have to pay £700 or so to repair. As a full-time student I don't have that kind of money.. I don't even have £60. - I find it annoying how they didn't even fully check the problem out.. just a "possibly the logic board".
So what if I manage to click my fingers and have £700 appear right before my very eyes? I pay for the new logic board just to find out thats not really the problem? or maybe have the same thing happen again right after the 90 days that logic board is covered for? meaning I have to fork out another £700.
I am a massive fan of Apple.. I love their products. I have brought so many products of theirs.. now just 2-3 months after my warranty runs out.. I get this. They didn't even say sorry for selling me a faulty product and didn't offer to help out in any way. When I spend £1,299 on something I expect it to last A LOT longer than a year and 3 months.
I need my MacBook Pro very badly for College but now I can't do my work and if I want to do my work, I have to pay £700 for it.
What do I do? Who do I talk to? Is it possible to get it fixed without having to pay that kind of money?
I can't settle for anything less than a Mac. I love the OS way too much and need so many of the apps that are Mac-only. So no way am I going to forget this and buy myself some cheap PC CrapTop.

Unfortunately, if you cannot boot from the disc, it won't be possible to do any diagnostic tests yourself.
It might be worth getting a second opinion. Is there an Apple authorized repair shop anywhere near you? If so, possibly you could take it there and see if they can diagnose it. You may need to pay a small fee for them to do this. But possibly someone might take a little more time with it and be able to give you a definitive diagnosis.
I'm grasping at straws, but you might be able to try resetting the SMC:
http://support.apple.com/kb/HT1411?viewlocale=en_US
I don't know if this would help or not--there are not many things to do when the computer is unresponsive and you can't use the keyboard or a disc.
Unless the problem was reported to Apple while the MBP was still under warranty, I don't think there is any way that Apple would be able to fix it under warranty. Did you ever take it in for any problem under warranty that might relate to its current situation?
I don't know if you might be up for trying to fix it yourself. If you are, here is a site that might be of help:
http://www.ifixit.com/
You have my sympathy--this has to be an exceedingly difficult situation for you. I will continue to think about this, and will post back if anything comes to mind.
Good luck!

Can you replace the keyboard of a MacBook Pro without replacing the logic board?

I had a bit of water damage on my MacBook Pro. I took it to the IT department, and he got the computer to work. The logic board and hard drive were intact. Here's the issues I'm having: the keyboard is next to destroyed. The buttons barely respond, and when they do, it's random letters that type, and they type without me pressing anything. I asked him about replacing the keyboard and what that may cost me. He told me that replacing the keyboard would mean replacing the logic board because they're integrated together, so essentially, that would mean replacing the entire laptop itself. I've been looking on here, and have seen that people offered other uninformed customers to go look for replacement costs for the keyboard, leading me to believe that it is replaceable without replacing the logic board. Can anyone confirm or deny this claim? I would greatly appreciate it. I gave the laptop to the IT department for the weekend. He's going to dry and dry it out over the next few days, so hopefully that works. I don't know what generation macbook this is, but I got it brand new in early October. Thank you very much in advance.

Why? Maybe he's ignorant and/or just didn't care to look into it? IDK
Look at the illustrated installation directions at same site. You may be able to do it yourself.
Overlooking details: with spillage, things can go wrong that aren't immediately apparent. Just something to keep in mind. No one can tell you if that's the case with yours or not.

Am I still elligable to the logic board progam?

Bought an iBook G3 in 2002... But it seems to have decided to wait until now to show Logic Board problems... The serial number in right in the middle of the elligible ones... But it is more than 3 years old obviously... Does anybody knows if I will have to pay for the repair, and if yes how much??
iBook G3 14'' Mac OS X (10.4.2)

My screen started having problems - opening up to a sky blue screen with no ability to work with it. A few days later it just stopped lighting up at all. It turns on and off. After reading the discussions here, I did check to see if my serial number fell within the range of serial numbers with the problem - and it did. (Read about that in another email.) I looked up the logic board replacement FAQs.
The first time I called Apple about the problem, the guy said that it would cost $745 at a minimum to get it fixed.
That answer didn't sound good, so I looked up these discussions and learned that people are still getting their ibooks repaired for free.
I called again and got a different person. I explained that my ibook fell in the right serial number range for the logic board replacement even though the deadline on the offer is supposedly over. I also told them that I'd just invested four hundred dollars in my iBook.
They asked me to wait, and five minutes later I was told a box would come for me to send my laptop back. I'm greatly relieved, but that was Sunday, and I still haven't gotten the box, so I hope it's not slipped through the cracks.
