The whole logic board is replaced by Apple, it gets a new serial number after that in the about mac dialog box.

I can't speak to whether this is common or not, but mine did not have a SN change when I had the replacement performed. Mine was sent into Apple via their mail-in service.

I seem to remember that you can identify it somehow under the 'About my Mac' -> System Report tab.

It doesn't really matter whether it's been "replaced" or not -- because the new ones are "the same as the old ones".

That is to say, a replacement will be "as prone to failing again" as was the original...

Ok, but I seem to have heard that there was a second series with less 'dubious' graphics chips of the same type, and I wonder whether these made their way into the replacement programme. Thanks.
