Apple's iBook Logic Board Replacement scheme has been extended once again, this time until March 18.

The scheme means owners of iBooks manufactured between May 2002 and April 2003 who experience a logic board failure leading to video display can have their Macs repaired for free, even when they are no longer under warranty.

Only specific models are covered by the scheme: iBooks with serial numbers in the UV117XXXXXX to UV342XXXXXX range.
