Which document is essential for initiating a warranty claim with Lenovo?

The original purchase receipt is essential for initiating a warranty claim with Lenovo because it serves as proof of purchase, confirming that the product is still within the warranty period. This documentation provides critical information about the date of purchase, which determines whether the product is eligible for warranty coverage. Warranty policies often require customers to present this receipt to validate their claim, ensuring that they meet the conditions stipulated in the warranty agreement.

Other documents, such as a customer feedback form or product user manual, do not hold the same importance in warrant claims processing. While they might provide useful information or context, they do not substantiate the purchase or guarantee service eligibility. Similarly, a warranty promotional flyer may contain details about warranty options but lacks the necessary proof of transaction required to process a claim.
