Coffee killed the logic board?

I need a new logic board for my iMac G4. There's a dead iMac (same one) on ebay that apparently had coffee spilled inside it. Would that kill the logic board too?

Firewire ports can lock-up. Disconnect the iMac from the mains electricity and leave it overnight. This may bring the Firewire ports back in.

Did Airport Card kill the Logic Board?

First, let me tell you that I am writing on my 12 yo son's behalf... after saving for two years he bought an iMac G4 15" flat screen in December 03. This year we gave him an airport card so he could finally have internet access. Three weeks later the logic board is fried.
When I spoke with Mac they had no record of that being a problem with this machine - and why would they since they refused to record my complaint?
Has anyone else heard of this problem?
Thank you.

bensapple, Welcome to the discussion area!
Is this a 700 MHz or 800 MHz 15" iMac G4? If so, the AirPort card shouldn't have caused any problem.
If this is a 1 GHz 15" iMac G4, then it requires the AirPort Extreme card, not the original AirPort card. If you installed an original AirPort card in this iMac, then the motherboard could have been damaged. Installing the AirPort Extreme card would not have caused a problem.
But if the card worked for 3 weeks, you had the correct card and it probably did not cause the motherboard to fail.
Hopefully you purchased AppleCare for this iMac...

My 2011 MacBook Pro does not start and stop after the apple appear, they said that the problem is a video problem and need to change the logic board. Cost almost same to buy a new one. Somebody have the same problem?

I have a MacBook Pro early 2011. Does not start. After the apple show, a blank screen appear. The service said that the problem is with the video plaquue in the logic board. Need to change. Cost lmmost the same than a new MacBook Pro. Somebody has the same problem? What we can do?

I hate to break this to you, but life isn't fair. If your job is that critically in need of a computer, then you should have a spare to use for just this kind of situation or have your employer provide you with a computer to use.
Computers break down, just like cars. If your car breaks down do you curse the car maker or get it fixed? Surely, you paid more for your car than the computer.
This is reality. Best get used to it because it won't get any better.

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 got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) and now my microphone is not working

I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) 3 days ago, I had a terrible experience as the genious who gave me my solid state disk for safekeeping lost my disk's brackets thus I had to wait 2 more hours until they find one after 10 days of waiting for the repair. I noticed some weird sounds, like somehting is moving with the mac 1-2 times, even if I have no mechanical parts other than the fans, but my real issue at the moment is that my microphone is not working. I can see the mic in the System Info however and in Audio Midi Setup. In the Audio Midi Setup I see that the master chanel is turned off and I can't turn in on. Ch 1 and 2 are on full. I also noticed the first seconds after the comp. boots the blue bar goes to the middle in the System Preferences -> Sound -> Input. Any ideas what to do or try? I do not want to go back to the apple store as it is 50 minutes away from here and I need my laptop as a computer science student. Everything else is working perfectly.

You need to call both the store that did the repair and Apple directly, warranty service or Apple care, and report this problem with both of them and get a ticket number of some kind (some kind of verification number) that the unit just came back from major service with this problem and that you want it fixed when you can lose the use of it, which is not right now.
Without doing something like that they could easily say it is damage not covered under the normal warranty.
God knows what the repair center did and did not do to it while it was there.
And depending on when you actually bought it the warranty could run out in the mean time.

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.

How many times did you change the logic board?

Hello everybody,
I"m the formerly proud owner of an iBook G3. Solowly I"m getting tired of the logic board problem. I have AppleCare, but by now I"m sending my iBook twice a year for repair!
By now I had my iBook sent to Care 5 times due to the logic board problem.
Now I"d like to know if this is average, low or high ranking on the G3 exchange scale,
Who can beat 5?
Michael

Michael,
Mine has been back three times.
If your iBook's logic board goes out again, I recommend that you call Apple and, instead of talking to Customer Support, immediately ask for Customer Relations. Be prepared with dates and details of your iBook's repair history, tell them you need a computer that is dependable, and your iBook just isn't. Then ask for a replacement. It has been known to happen.
Good luck.

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.

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.

Mac shuts down after boot. Is it the logic board?

mac shuts down after boot. Doesn't go beyond gray screen with apple. Is it the logic board?
I do not have the start up disks to safe boot or check the hardware.
Any ideas what the problem is or is it junk? It is 8 years old.

Shutdown your machine. Hold down the shift key. Poweron. Wait awhile Wait awhile while you harddrive
is being checked.
http://support.apple.com/kb/ht1455
I'd let the machine sit for awhile in open firmware & see if it stays alive. Do a few prints.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

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.

The logic board on my MacBook Pro has failed. How do I retrieve all my data from the hard drive?

The logic board on my MacBook Pro has failed. How do I retrieve all my data from the hard drive?

Remove the drive and put it in an external enclosure. Backup the drive completely. Repartition and format the drive. Replace the drive into the computer. Take the computer in for the logicboard replacement.

My mac book pro crashed and the logic board died. They said that i could get the hard drive out and it should have all my files on it. How do i get them off and put them on my new computer?
