What must customers keep as proof for warranty service eligibility?

To establish warranty service eligibility, customers must retain proof of purchase and service history. The proof of purchase typically includes receipts, invoices, or any documentation that verifies the transaction date, product details, and the authorized retailer. This is essential because manufacturers like Lenovo require this evidence to confirm that the product is still within the warranty period and was purchased through legitimate channels.

Service history documentation also plays a vital role as it records any past repairs, servicing, or warranty claims associated with the product. This information helps ensure continuity of service and informs technicians about previous issues.

Maintaining these records allows customers to demonstrate their right to warranty service, ensuring that any claims made for repairs or replacements are honored. Suggestions to retain records of product ratings and reviews, insurance documents, or software licenses do not provide the necessary validation for warranty eligibility and may not satisfy warranty claim requirements.
