As noted by MacTalk [via setteB.it], a support document last updated on May 26 details Apple’s new “MacBook Bottom Case Replacement Program” which, for MacBooks shipped between October 2009 and April 2011, grants owners of white MacBooks with peeling rubber cases a free replacement of the entire case both in and out of warranty.
Apple has determined that under certain circumstances the rubber surface on some MacBooks may separate from the bottom case of the system. MacBooks shipped between October 2009 and April 2011 may experience this issue.
Apple will replace the bottom case of any affected MacBook, free of charge, that exhibits the issue.
Apple offers three options to replace the bottom case for free: owners can visit an Apple Store by setting up an appointment at the Genius Bar to get the replacement; alternatively, Apple Authorized Resellers can also replace the MacBook’s case. For those not willing to visit an Apple Store or reseller, Apple is offering a free replacement kit online (which includes “a new bottom case, screws, a Phillips head screwdriver, and instructions”) provided you live in one of the 22 supported countries (though the program is presented as “worldwide”) and you have access to your MacBook’s serial number. More details can be found on the program’s official page.
The white MacBook is due an update and several rumors claimed Apple was looking to discontinue it to make room for the popular MacBook Airs as the default entry line. The white MacBooks were also affected by other hardware issues in the past, such as discoloration problems and cracked cases.
