How to Find the Serial Number (SN) of a Lenovo Laptop？

You can locate the serial number (SN) of your Lenovo laptop using the following methods:

Method 1: Check the Physical Label

1. Turn over your laptop and look for a sticker on the bottom (usually near the battery compartment or cooling vents).

2. The label will display “SN” or “Serial Number” (a combination of letters and numbers, possibly with hyphens).

3. On some models, the SN may be inside the battery compartment (remove the battery to check).

Method 2: Check in BIOS/UEFI

1. Press F2 or Fn+F2 repeatedly during startup (some models may use F1/Del).

2. Navigate to the Main or System Information tab and look for Serial Number.

Method 3: Use System Commands (Windows)

1. Using Command Prompt:

   • Press Win + R, type cmd, and press Enter.

   • Enter one of the following commands:

     bash

     wmic bios get serialnumber  

     or

     bash

     wmic csproduct get identifyingnumber  

   • The SN will be displayed.

2. Using PowerShell:

   • Press Win + X and select Windows PowerShell.

   • Enter:

     powershell

      

     Get-WmiObject Win32_BIOS |Select-Object SerialNumber  

      

Method 4: Use Lenovo Official Tools

1. Download Lenovo Vantage or Lenovo PC Manager from Lenovo’s official website.

2. Open the app and check Device Information or Hardware Details for the SN.

Method 5: Check the Packaging or Invoice

• The original box or purchase invoice usually prints the SN on the label or warranty section
