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.
