Contact AppleCare. They should be able to give you
an honest answer.
No question that they should, no guarantee that they can or will. Keep in mind that Applecare reps are restricted by their administrative policy directives. Also be aware that class action looms.
There seems, however, to be a de-facto acknowledgment by Apple that fatal flaws exist within the original AND replacement logic boards available within certain range of serial numbered 15" PowerBooks.
After the second logic board failure, and a HD replacement, Apple is replacing my PowerBook, which lies within the serial# range of their extension program, with a Pro Book of comparable configuration.
My PB was just over 1 yr. old when the first failure occurred, normally performed for a few days after repair, then resumed the previous symptoms of memory drop out, intermittent booting failure, etc.
As one peruses these discussions, there are a host of issues that directly relate to logic board performance on a wide range of Books, and it seems Apple has no viable hardware remedy. The replacements are apparently as fault prone as the original. For those out of warranty it's salt in the wound.
I'm now aware of logic board issues with the Pro Book as well, so there's no guarantee that future performance of that model will be more reliable, time will tell.
It's beyond unfortunate, inconvenient, and costly to everyone affected to have system failures so ill understood by Apple, and if understood, so narrowly acknowledged. For a company that promotes itself as above the norm, it's credibility is seriously threatened by it's apparent limited sense of honesty and responsibility to it's customer base, or for that matter it's investors.
Anyone experiencing repetitive failure related to logic boards should not have to be subjected to stonewalling by Apple for a suitable replacement, nor be misdirected to a course of time consuming repairs that are known by them to be futile, by reason of the benefit economics of deferral .
If you have experienced multiple failures of logic board related function, either be resigned to live with it's likelihood of becoming a lifestyle, or resolve to press Apple for the appropriate replacement.
