You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by this recall.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue that Apple calls "VST" (for "Video Switching Test.") Ask for it. A "Failed" result means that the fault is present. However, according to reports, some units may pass the test, and yet still be deemed eligible for repair under the program. Your experience may vary.
Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
The model was discontinued on February 24, 2011, so the recall has nominally ended. Some units may have been sold after that date by Apple as refurbished, or by resellers as new, and they might still be covered.
Some owners report that their unit was repaired under the program after the deadline had passed. Others report that the repair was covered by the extended warranty from a credit-card issuer. Again, your experience may vary.
Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
If you're dissatisfied with Apple's response, please keep in mind that no one here represents the company or can help with customer-service issues.
