Apple launched a program to replace the bottom cases of the laptops, for owners who purchased their computers between October 2009 and April 2011.

If you’ve been affected by the problem, you can either take your computer to an Apple store or service provider or send away for a do-it-yourself repair kit.

The kits, available on Apple’s Web site, come with a new bottom case, a Phillips head screwdriver, screws and instructions.
