Under the Hood

How It Works

The tool interfaces directly with Lenovo's Support API through their getIbaseInfo endpoint. When a serial number is submitted, the API returns the complete product record including the Machine Type (a 4-character identifier that uniquely identifies the hardware configuration), processor model, installed RAM amount, storage type and capacity, and the full product name. The system handles Lenovo's API response format and extracts the relevant specification fields. For batch processing, Excel files with multiple serial numbers are processed with appropriate rate limiting. All results are compiled into a formatted Excel export with one row per device.

FAQ

Frequently Asked Questions

How do I check my Lenovo warranty?

Enter your Lenovo serial number above and the tool queries Lenovo’s official support API in real time, returning your warranty status (in or out of warranty), the warranty end date, and the coverage type — alongside the machine type and full hardware specs. It runs a Lenovo warranty check on a single device or on a whole batch of serial numbers at once.

Where do I find my Lenovo serial number?

The serial number is printed on the label on the bottom or back of the device, and is also shown in the BIOS/UEFI setup screen and in Lenovo Vantage. On Windows you can run 'wmic bios get serialnumber' in Command Prompt to read it without turning the machine over.

What does my Lenovo warranty status mean?

The tool reports whether the device is in warranty or out of warranty, the regular warranty end date, and the coverage type (for example base depot, onsite, or an upgraded or extended warranty). Use the end date to confirm exactly when coverage lapses before resale or retirement.

Is the Lenovo serial number the same as the machine type?

No. The serial number is unique to each individual device, while the Machine Type is a 4-character code that identifies the model and hardware configuration. This lookup returns both, plus processor, RAM, storage, and the full product name.
