How To Replace a Logic Board

I have two of the same exact G4 800mhz laptops, one with a bad logic board and one with a cracked display, put them together and I have a brand new laptop, although I cant seem to figure out why I cant get the logic board out. How can I do this? Both laptops are out of warranty and basically end of life for me so trying the swap whether it works or not will be of no loss to me. But i do not see myself paying apple or some apple technician to do this... can anyone help me at all???

Brave stuff Chris!
A couple of places to start:

Then you're on your own.
Good Luck.
PS Mightn't it be easier to change the display rather than the logic board?

Is replacing the logic board going to make my early 2011 Macbook Pro as good as before

I have an early 2011 15" Macbook Pro that just crashed completely days ago. I sent it to the genius bar and was told that I need to replace the logic board and it costs amost $1000. I'm thinking whether changing the logic board actually means that my macbook would be as good as before. I mean I'm not having high expectations but I hope that it would at least lasts for another few years. I've only had this Mac for three years and I'm not sure if its a consistent problem for the early 2011 models regarding the logic board but I sure had mine replaced for at least three times in the first year when I got it. I'm not sure if I should just use that same money to get a brand new laptop, problem is, I'm quite unwilling to switching to a windows system if you understand how it feels.

The first thing I'd look at is your hard drive ... is your free space 10% to 15% or more of the total capacity? If not, that would account for what you're seeing.

Should I spend $960 to replace the logic board of a 5 year old iMac?

my 5year old iMac cannot power on after a power shut down, and the technician of apple service told me that they checked everything and it's the logic board that needs replacement which will cost $960 ...
Should I proceed to fixed it in this rate? or just leave it and look forward ...?
What's the typical life space of an iMac? Can 5 years be regarded as good enough?
Frustrated ...I'm
Thanks!

Thank you, guys!
I decided not to replace the logic board.
However, I don't know what to do with the hard drive taken out from the broken iMac which I assume is in good condition. I have another post here to ask help on how to retrieve data from this hard drive although I know the login password for both the OS X and Windows7 installed on that drive ...
Hope you guys can kindly advise, too!
Thank you very much!

How can I differentiate logic board problem from display problem?

I have been given an iBook G3 900MHz (one of the models known to have logic board issues.) When I boot it up, I get the Apple chime, the hard drive spins, and the caps lock and num lock lights light up. Sometimes the display comes on, sometimes it does not. When it does, it flickers and goes off and on. I don't get lines or pixels or anything that I have seen described as being indicative of logic board failure. As far as I can tell, the computer works fine otherwise.
So, how can I be sure the problem is logic board-related and not an issue with the inverter board or the display cable?
I was also wondering, how much trouble - if any - is Apple giving people about replacing logic boards on certain models of iBook? This one should be eligible, as its serial number falls in the right range and it was bought in Oct. '03, which was within the past three years.
Thanks!

there was a period when the display showed colored lines and pixels
Classic logic board symptoms.
The iBook freezes a lot
Mine did, too, with the logic board problem.
my gut tells me the problem is logic board-related.
My gut tells me your gut is probably right.
My question about repair coverage is this: According to Apple's support site, where I entered the serial number, this computer's "estimated purchase date" was October 3, 2003. But the owner no longer has any actual proof of purchase; no receipt, no packing slip, nothing. Is that needed to have Apple replace the logic board?
No. As I said, I bought mine, used, on eBay. I called in when I recognized the logic board symptoms (I had been working these boards for over a year at that point), they sent a box. It went out on Wednesday. They got it, fixed it, and shipped it back to me on Thursday, and it was back in my hands on Friday. (Practice makes perfect, I guess.)
Also, does Apple make their determination of age from when the computer was purchased or when it was built?
Purchase date only.
Or does that decision depend on if a person can produce a receipt or not?
Nope. The only paperwork I sent in with mine was the slip Apple sent in the box to indicate what all I was sending them (adapter, battery, extra RAM). What good would an eBay seller's receipt have done?
I probably have to go to my local service center (in NY that's a place called Tekserve, which is a great place to get a computer fixed, but the wait to be seen averages over an hour!)
Don't mess around with Tekserve. Call Apple at the number listed on the FAQ page:
http://www.apple.com/support/ibook/faq/
Thanks again for your input. I appreciate it.

I replaced the logic board- now nothing...

This is really a continuation of this thread:
http://discussions.apple.com/thread.jspa?threadID=2542941&tstart=0
It is now the end of September and I have been unable to use my Power Mac since early August/Late July.
to recap: I replaced my logic board, but then the machine wouldn't turn on. The power button wouldn't stay illuminated and the screen remained blank but I could hear the whirring of fans and maybe drives.
I brought the tower to the Genius bar where they opened it up and promptly told me my CPU was fried.
Fortunately it was still under warrantee And OWC said send it on back and we'll see what we can do.
Turns out the Newer Technologies 2.0 ghz CPU has been discontinued. The folks at OWC were trying to find out if they could get it rebuilt or just what they could offer me to honor the warrntee on a dicontinued item.
So we agreed to a dual 1.6 CPU that I received in the mail Tuesday and installed last night.
Unfortunately the same thing happened. I hear it try to start but there's no chime and the on/off button only remains illuminated as long as I hold it in.
Could it be a bad logic board?
because the CPU is an aftermarket product, it comes with firmware to be installed. When I replaced the logic board, did it maybe not recognize the CPU? (I'm grabbing at straws here.)
I will probably bring it in to the Genius bar again and have them look at it, but I just thought I would try here first in case anyone might recognize the symptoms.
thanks.

the heatsink came out first, and then the card with the processor.
The processor chip and card are one assembly called a daughter card.
I just don't know how to go about re-installing it. Is there a temporary fix short of solder?
It's not solder.
The OEM CPU and heat sink have thermal tape that is hard to break when cold.
When hot, the heat sink is easily removed.
Simply reinstall the CPU daughter card, put a bit of thermal compound on the old tape, and fasten the heat sink.
This will work well enough to run the firmware patch.

I couldn't locate a voltmeter that would work at this level.
Any electronics store will have a volt ohm meter; Radioshack, Fry's, etc.
They are inexpensive.

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.

When Replacing the Logic Board....

I recently sent my iBook in for a mulittude of repairs, including a problem with the CD R-W/DVD drive not working right. To fix this they replaced the Logic Board, but when doing so the Hard Drive was wiped. I've had my logic board replaced 100s of times on an iBook G3 without that happening. Anyone know why that would have changed this time?

Uneconomical to replace the logic board in 2009 Mac Air. Any comments please?

I have a 2009 Mac Air which has been found to have a faultyskin sensor. I was advised that it would be uneconomical to replace the logic board. I would appreciate any comments.

What was the repair cost quoted? Compare amount to the typical selling price of a similar model on eBay. I suspect the repair will cost very close to, if not more, than the selling price. If so consider, selling it for parts and buy a new or refurbished one.

Black screen after they replaced my logic board twice

I have been getting black screens on my mac book about a month or so after i bought it i take it in all the time they say we ran tests nothing is wrong with it then i get it home and i get another black screen finally after a couple months the first time they replaced my logic board / graphics card. It continued to happen so i took it back in they ran tests said they could find nothing wrong i showed them a video of my macbook pro black screening they said they would check the memory they did and said it was loose so they replaced my logic board AGAIN now on the second day of getting my macbook pro back it has black screened AGAIN this was in windows boot camp but when it happens on that side it always happens on the mac side can anyone give me any advice / suggestions on what to do about this please?

I have been getting black screens on my mac book about a month or so after i bought it i take it in all the time they say we ran tests nothing is wrong with it then i get it home and i get another black screen finally after a couple months the first time they replaced my logic board / graphics card. It continued to happen so i took it back in they ran tests said they could find nothing wrong i showed them a video of my macbook pro black screening they said they would check the memory they did and said it was loose so they replaced my logic board AGAIN now on the second day of getting my macbook pro back it has black screened AGAIN this was in windows boot camp but when it happens on that side it always happens on the mac side can anyone give me any advice / suggestions on what to do about this please?
Below is the last kernal panic before they replaced my logic board for the second time

Replace the logic board in my iBook with any processor speed?

I need to replace the logic board in my iBook G4, 933 MHz, 14", dual USB. Are the boards with the faster G4 processors interchangeable? I have not opened this machine is some time and the images I have come across in my minimal search this evening seem different for different processors.

No, they are not interchangeable.

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.

Why in the world does it cost sooo much to replace a logic board for your water damage macbook pro? As if apple hasn't made enough money to allow some people to save some money for their laptop..

Do you think Apple should reward your clumsiness or lack of caution by giving you a logic board for free, or at cost? Come to think of it, shouldn't they just give you a free new computer, and be grateful to you for taking it off their hands?
Apple isn't a charity operated for the benefit of the careless.

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.

How much does a logic board cost?

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.

Usually if you have to pay for a new logicboard, you might as well buy a new machine because basically the whole computer is the logicboard.
I've done some thinking about if it's worth it or not to get your machine fixed and have come ot this sort of rough forumla.
A Mac has a life expectancy of about 4 years
One needs to determine where along their life expancy their machine is.
Then divide the investment into the machine, including the cost of new software that won't work on the new OS, by the 4 years, then from that determine if it's worth it to spend the money to get the remaining life out of it or to sell it once fixed and come out ahead.
If a machine is just out of the 1 year warranty, no AppleCare, costs $4000 originally, then it might be cost feasible to pay another $700 to get the $3000 due on it. Sell it used for $3500 say and the burn is only $200 (4700-3500 - one year use $1000 = $200)
Usually third party software a mere year old the developer won't have a paid upgrade, but then again with Appel issuing new OS X versions left and right they may, depending upon how much you pay for third party software and what the upgrade price is also is a factor..
