SERVICE OFFERING DETAILSWarranty Upgrade to Onsite + Tech Install CRUWarranty upgrades to onsite service provide next business day (in many areas) dispatch of a Lenovo authorized technician to provide repair. If Lenovo determines your product problem is covered by the product warranty & cannot be resolved over the telephone, a technician will be dispatched to arrive on-site, typically the next business day, in major metropolitan areas. Service is available during Lenovo's normal in-country business hours. Calls received after 4: 00 p. m. local time will require an additional business day for service dispatch. On-site service is available only in metropolitan areas, & next day service is not guaranteed. Adding the Tech Install CRU upgrade option extends all internal parts customer replaceable to factory replaceable parts.
