Apple Computer may begin substituting 700MHz logic boards for some 600MHz iBook models that are in need of repair, due to "unforeseen inventory constraints" of the 600MHz iBook logic board and G3 processor, AppleInsider has learned.
The substitution would provide a 100MHz speed increase to some 600MHz iBook customers who were the unfortunate recipients of slightly defective iBooks from the company's iBook G3 product line.
Apple began informing service providers of the substitutions earlier this week, noting that they are "temporary only and subject to change without notice." The substations apply to service centers in US, Canada, and Latin America.
The company asked that its service providers "not set any customer expectations as to the type of logic board that may replace a defective module," as "not all defective iBook logic boards will be replaced with an upgraded logic board."
Only iBook models with a 600MHz '661-3311 logic board' are eligible for the potential 700MHz '661-3312 logic board' replacement.
The substitutions are likely a result of Apple's Expanded iBook Logic Board Repair Extension Program, which covers repair or replacement of logic boards in iBook models manufactured between May 2001 and October 2003 that are experiencing video-centric component failures.
Apple announced the repair program in February, after word spread that hundreds of defective iBook owners were organizing a class action lawsuit against the company.
