PC World reports that MacBook Pro owners who bought a laptop with an Nvidia graphics processor in 2007 and 2008 may be eligible for free repairs

The affected Mac models include 15- and 17-inch MacBook Pros bought between May 2007 and September 2008. Not every laptop sold during that period is eligible for the settlement--the MacBook Pro models have to contain an Nvidia chip and feature an eligible serial number. (You can check on the former using the About This Mac panel, and confirm the latter on this lawsuit settlement page.) The laptop also needs to be experiencing the scrambled video or blank screen issues.
