As reported in AppleInsider (must be amaze how they pick up such changes), if you have bought a MacBook Pro 15-inch or 17-inch between May 2007 and Sep 2008, before the Unibody MacBook Pros, that uses NVIDIA GeForce 8600M GT graphics processors, you are covered for three years from the date of purchase should there be any problems arising from the graphic chip.

Those visiting Apple’s support page for the video corruption and failure issues suffered by this portable generation have noticed that Apple has quietly added an extra year to its coverage, giving owners of the affected MacBook Pros free replacements as late as September 2011 depending on the date of purchase.

I have one of the listed machine but thankfully, my screen is still working fine and hopefully need not have to send in for replacement.
