MacBook Pro Logic Board Failure

Probably boards are shipped to repair center with the correct SN already, I mean, they're ordered for a specific SN, since the SN is unique and all your computer historical is kept vi this unique key.

If the motherboard is changed the serial number will also change unless the job of replacing it is not done correctly, in which case there will be no serial number.

it's weird

The employee man told me that my logic board has been replaced but i still got the old SN

does he tricked me or something?

I don't think so, since the SN is the unique key to identify your mac, they should keep the same SN or the would not be capable of track your Mac, unless they tied to SN together, but that would be tricky...

Once I've sent my Tektronix scope to service, under their 5 years warranty, they replaced the board and kept the same SN for the scope, as in the back cover label, so I thing its correct.

And you know this, how?

"Should" suggests that you don't know and are guessing.

Well i don't, and no one them Apple guys knows that, anyone knows Apple policy? If you do, let us know

Replacing the board should result in a change of s/n, if left blank some Apple Services will not work.

Search this site, it's a fairly common situation

Ok, both logic makes sense, its a matter of convetion, but do they replace the back cover as well? The SN must match...

No

Its that kind of weird, is not? I think the SN must match, the SN is for the hole machine, not for the logic board itself, if you replace your cars engine ECU, it will get the cars VIN... usually the SN is tied to the biggest part of the machine, could be the Logic board of the computer itself, the unibody.. depends of your logic...

In mine, if you change the Board SN, and the SN is holden by the logic board and the rear cover, they should match...

It's not a car.

If you have an opinion please share it with apple at: www.apple.com/feedback.

Apple is supposed to put the original serial number back on the replacement logic board. they have special software to input the original serial number to a replacement board that comes with No serial number. It is the only way for that system to be registered to the owner. It does not have a New serial number. It has the same serial number. If it is given back with no srial number then they did not do a proper job and it need to be taken back to have the original serial #, the one that is etched on the bottom of the case, put on the replacement board.

One case = one serial number. No matter how many parts or what parts have been changed inside that case.

So I share the same toughts as you...

It is not a Thought. That is what is supposed to be done. The serial number must stay the same as what it was when it got shipped from the factory.

One system, One serial number. No matter what has been changed. Including any case parts.

You are absolutely right! I had the logic board replaced on my Macbook Pro and when I collected it I checked and the serial number did not match the one on the bottom of the case and under the 'About this Mac'. I spoke to Apple and they asked me to bring it back to the shop so that they could replace the logic board again but with the original (correct) serial number. When you register your apple product, the serial number identifies that product with the owner who is registering it.
