Apple announced last week via a support bulletin that it is replacing defective Time Capsules manufactured between February 2008 and June 2008. The defective units are plagued by a power problem that causes the unit to either not power on or power off unexpectedly. If you experience this problem, contact Apple, an authorized service center, or setup an appointment at your local genius bar to arrange for a repair or a replacement. Good news for those who already paid for a repair; Apple is going to issue a refund for the complete cost of the repair service.
