Apple has begun a repair program to fix MacBook Pro machines sold between February 2011 and February 2013 that have problems with distorted video, no video, or unexpected system restarts.
As of February 20 in the United States and Canada, users with affected machines will be able to visit an Apple Store or Apple Authorized Service Provider to receive repairs for their MacBook Pros at no charge.

Affected products include 15 and 17-inch MacBook Pro models manufactured in 2011 and the 15-inch Retina MacBook Pro manufactured between Mid 2012 and Early 2013. Users can see whether their computers are affected by using the "Check Your Coverage" tool on Apple's site.
