Warranty

The Lenovo B300's hardware has a one-year Customer Replaceable Unit (CRU) parts-only warranty with

9x5/next business day (NBD) terms.

Some countries might have different warranty terms and conditions than the standard warranty. This is due

to local business practices or laws in the specific country. Local service teams can assist in explaining

country-specific terms when needed. Examples of country-specific warranty terms are second or longer

business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will

dispatch a service technician to the customer site to perform the replacement. Onsite labor under base

warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units

(FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor

under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement

parts that are under base warranty (including FRUs) that 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 spares parts.

Also available are Lenovo Services warranty maintenance upgrades and post-warranty maintenance

agreements, with a well-defined scope of services, including service hours, response time, term of service,

and service agreement terms and conditions.

Lenovo warranty service upgrade offerings are country-specific. Not all warranty service upgrades are

available in every country. For information about Lenovo warranty service upgrade offerings that are

available in your country or area, refer to the following resources:
