ThinkPlus warranty upgrades are only available from Lenovo. These ThinkPlus offerings provide up to five years of hardware maintenance coverage, including the machine warranty period, in an electronic format. The easy registration process of the attractively priced ThinkPlus offerings helps to ensure that a high-quality maintenance service can be provided. These ThinkPlus offerings are available through the same Business Partners who sell the related Lenovo hardware. The intention is to enable the Business Partner to offer his customer an off-the-shelf warranty upgrade or post-warranty offering at the time the customer purchases the machine.
