Cip burnt on the logic board, but it still works!

Recently when i was using the MacBook (Late 2011, 13', 2.4MHz i5) without it been plugged in, it turned off all of a sudden with the "chich" sound and a puff of smoke came out. I thought my Mac died. But when i turned it on, it stated to work fine (checked with diagnostics, everything worked fine).
So, Just to be sure i took it to the apple service centre, and they showed me that a chip on the logic board (below the fan) have been burnt. but the wonder is, the mac works fine. it would take me around $650+ for me to replace the logic board. can anyone please tell me if this is something i can live with and not replace the logic board ?

arrow shows the chip that is burnt

Late 2007 MBP went black screen. I've been told it is the logic board but not due to the Nvidia GPU

My sister's Oct 2007 MBP just died suddenly. Yesterday when she opened Entourage it said it couldn't open because there wasn't enough memory. We rebuilt the Entourage Identity and it then worked fine. It wouldn't shut down though, and when woken from sleep went gray then black. The apple store here in Spain says it is the logic board but not due to the Nvidia GPU, and it's not worthwhile to replace it. Is it possible they are wrong? They also say it will cost about 800 Euros to replace! It's a 2Ghz Core 2 Duo/2GB/256MB, EMIC No: 2136.

Well, if you've indeed tried EVERYTHING, then you'll need to bring your phone to Apple for evaluation.

Ugh. I think it's the logic board but not sure.

It freezes, wont start up. i reinstalled tiger and it froze again. from what ive been reading from all the forums its the logic board. i dont think the ram has anything to do with it. i started it in safe mode and it froze again. i did the "shift + ctrl + option + command+ repeatedly simultaneously hitting power. then wait 5 seconds and hit power again," and sometimes it starts. anything else i can do before someone at the genius bar ignores me and tells me to get apple care?

It definitely sounds like the Logic Board. Check the serial number against the serial numbers that are vaild for the Logic Board Replacement Program and hope (if you have a God, pray to it) that your's is one of the ones within the range because, otherwise, it's gonna cost you roughly the price of a new macbook to get it fixed. If it's covered, it's free.
Mine, unfortunately, wasn't covered so I now have a rather expensive paperweight that I will be finished paying off next month.
Yeah, I'm a little bitter...
Good luck!

I left my iPhone on top of my car. At about 50mph it fell off. It had spider web cracks all over the back and a small section of the front. But it still works perfectly. Thanks for making such a tough phone!

I found my iPhone on the side of the on-ramp thanks to "Find my iPhone". It was within 5 feet of where it had been tracked.

I long ago gave-up on Apple Support Communities as a source of technical info, and instead drop-by from time-to-time for entertainment purposes.
Thanks for the great story!

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.

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?

New problem WITH the logic board replacement

Hi Everyone,
I sent my computer in recently to get a whirring fan noise repaired, but after receiving my macbook, I have developed the whine.
They tell me they replaced the logic board, but I didn't even ask for one. Now I have a loud whine coming from the left side of my computer near the adaptor.
I guess my question is, is it possible to develop the whine after the logic board has been replaced and why Apple replaced a logic board which had no whine.
Thanks for the help.

You will not be able to order a logic board from Apple. You can look at websites such as iFixit.com and Powerbookmedic.com where Apple MBP parts are available. Costs will be shown there. In additions there are instructions available if you prepared to install it yourself.
Ciao.

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.

I bough a refurbished iMac last year, unfortunately Im in need of a Logic board, but when I search FD093LL/A, no company seems to recognize this model but I do see all models, or at least most, starting with MD...whats the difference?

I bought a refurbished iMac last year, unfortunately I'm in need of a new/used Logic board, but when I search and contact Company with Mac parts, no one seems to recognize FD093LL/A witch makes it tough to identify parts, but I do see most Part Numbers starting with MD. Any reason why?
Thank you

Refurbished models have a different order number. Replace the F with an M and see if the specifications listed match your computer’s.

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.

Cip burnt on the logic board, but it still works!
