Symptoms

In July 2008, NVIDIA publicly acknowledged a higher than normal failure
rate for some of their graphics processors due to a packaging defect. At
that same time, NVIDIA assured Apple that Mac computers with these
graphics processors were not affected. However, after an Apple-led
investigation, Apple has determined that some MacBook Pro computers with
the NVIDIA GeForce 8600M GT graphics processor may be affected. If the
NVIDIA graphics processor in your MacBook Pro has failed, or fails
within *three years* of the original date of purchase, a repair will be
done free of charge, *even if your MacBook Pro is out of warranty.*
