Lenovo warranty service upgrade offerings are region-specific. Not all warranty service upgrades are available in every region. For information about Lenovo warranty service upgrade offerings that are available in your region, refer to the following resource:

Contact a local Lenovo representative for details on region-specific support and details on response times.

Some regions might have different warranty terms and conditions than the standard warranty. Local Lenovo sales representatives can assist in explaining region-specific terms when needed. Examples of region-specific warranty terms are second or longer business day parts delivery or parts-only warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, a service technician is dispatched to the customer site to perform the replacement.

If warranty terms include parts-only warranty, only replacement parts that are under warranty will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spare parts.

For service definitions, region-specific details, and service limitations, please refer to the following resources:

Note: These resources might contain additional SLA options that are not offered by Lenovo. Please contact a local Lenovo sales representative in your region for any specific questions.
