Apple has acknowledged that a discoloration problem exists with some of its white 13-inch MacBook notebooks, where the casings of the computer may turn shades of orange after very little usage, and is repairing MacBooks that exhibit the issue.

“Some white MacBook computers may exhibit discoloration on the top case after some use,” the company wrote in a note to its retail sector and service partners. “If this issue occurs […] and the computer meets certain requirements, Apple will cover replacement of the affected parts under warranty.”

In order to be eligible for the extended warranty repair, a customer’s MacBook must have a serial number that falls within the range of 4H617XXXXXXXX to 4H627XXXXXXXX. The notebook must be irresponsive to approved cleaning solutions.

In replacing the top case — the affected portion of the computer containing the palmrest area — Apple will also replace the display bezel, people familiar with the repair process say.

The warranty extension is being made available to MacBook customers in all of Apple’s major markets, including the United States, Canada, Europe, Latin America, Asia-Pacific and Japan.

Customers afflicted by discolored MacBook syndrome should contact an Apple Care support representative by phone (1-800-800-2775 in US) or bring their computer to a local Apple retail store to arrange for diagnosis or repair.
