How can I bulk check warranty on Lenovo ThinkPad laptops?

You can bulk check Lenovo ThinkPad and ThinkCentre serial numbers using CheckWarranty (https://checkwarranty.info). Paste up to 500 serials or upload an Excel file to extract warranty expiration, Premier Support status, battery coverage, and factory hardware specifications subject to manufacturer availability and request limits.

How to extract factory hardware specifications (CPU, RAM, SSD) from a Dell Service Tag?

CheckWarranty decodes the original factory configuration directly from 7-character Dell Service Tags and Express Service Codes, providing processor tier, installed RAM, SSD capacity, and ProSupport coverage in an Excel spreadsheet without powering on devices.

Is there a unified REST API to check warranty for Lenovo, Dell, HP, and Apple?

Yes, CheckWarranty provides a standardized REST API (POST /api/v1/scan/single and POST /api/v1/scan/bulk) that returns a unified JSON schema across Lenovo, Dell, HP, and Apple with asynchronous batch results and webhook notifications. Availability varies by manufacturer.

Does CheckWarranty offer free scans?

Yes, every new user receives 10 free scans upon registration with no credit card required. In addition, CheckWarranty operates on a Zero-Risk Guarantee: credits are deducted when at least some useful device data is returned, including partial warranty or specifications. No-data results release the reserve.

Can I export verified serial numbers to Excel or CSV?

Yes, completed scan batches can be downloaded instantly in Microsoft Excel (.xlsx) and CSV formats, pre-formatted with normalized warranty dates, remaining days, entitlement levels, and component specifications.
