      • Announce date: 18 Sept 2012 (Worldwide)
      • Availability date: 12 Oct 2012 (Worldwide)

      If warranty service is required, call the Customer Support Center. The Customer Support Center will assist with problem determination and initiate shipment of a replacement unit, if needed, to the customer's location by express delivery. For calls received by 5:00 p.m. customer's time, in most cases, the replacement unit will arrive within two business days (excluding holidays). The replacement unit becomes the property of the customer in exchange for the failed unit, which becomes the property of Lenovo. Pack the failed unit into the shipping carton that contained the replacement unit and return to Lenovo. Transportation charges, both ways, are paid by Lenovo. Failure to use the carton in which the replacement unit was received could result in charges incurred by the customer for damage to the failed unit during shipment.
