Where is the serial number on Lenovo laptop？ How to find it?

In daily use of Lenovo laptops, many users may encounter situations where they need to provide the serial number (S/N), for example:

• Applying for after-sales warranty or repair service

• Checking the warranty period and product information with serial number

• Downloading the correct drivers or firmware for your Lenovo laptop model

So, where is the serial number on a Lenovo laptop? And how can you find it?

What is the Serial Number of a Lenovo Laptop?

The Lenovo laptop serial number (commonly referred to as S/N or Machine Number) is a string composed of letters and numbers. The format may vary slightly across different series and production periods. According to Lenovo’s official definition, the serial number is usually combined with the machine type, formatted as TYPE xxxx-xxx + S/N xx-xxxxx, where the part after “S/N” is the complete serial number.

It is important to note that special characters such as hyphens are only separators. When entering the serial number for queries or validation (such as Lenovo warranty check by serial number), they are not required, and the letters are not case-sensitive.

This code not only serves as the device identity identifier but also acts as the key credential for warranty service, driver download, and technical support. When buying a second-hand Lenovo laptop, if the serial number sticker is missing or the format looks suspicious (not alphanumeric), there may be a risk of a tampered serial number, so you should pay extra attention.

How to Find the Serial Number on a Lenovo Laptop

There are several ways to locate the serial number:

1. Laptop Body Label

On most Lenovo laptops, the serial number can be found on the bottom case label, marked as “S/N” or “Serial Number.”

For older models with removable batteries, the serial number may also be located on the label inside the battery compartment.

The serial number is usually printed on the barcode label of the packaging box as well. If you have kept the Lenovo laptop packaging or invoice, you can also retrieve the serial number information from the sticker there.

2. Using Lenovo Vantage or Lenovo PC Manager

• Open the Lenovo Vantage or Lenovo PC Manager software.

• Go to the “Device Information” page and click “Hardware Configuration” in the upper-right corner.

• Under the computer model section, you will find the Machine Number, which is the serial number.

3. Through Windows Command Prompt

• Press Win + R to open the Run dialog.

• Type cmd and press Enter to open the Command Prompt.

• Enter the command:wmic bios get serialnumber

• The SerialNumber displayed is your Lenovo laptop’s serial number.

4. Using Windows PowerShell

• Open Windows PowerShell.

• Type the following command and press Enter:wmic bios get serialnumber

• The system will show the Lenovo laptop serial number.

5. Keyboard Shortcut

• Press FN + ESC.

• (Note: this shortcut requires the hotkey driver to be properly installed before it works.)

6. In BIOS

• When booting up, repeatedly press F10 (or F2, F12, depending on your Lenovo laptop model) to enter the BIOS menu.

• Look for “Product Serial Number” or “Serial Number” in the BIOS information page.

By mastering these methods, whether you need to check Lenovo warranty status by serial number, request repairs, or download drivers, you can quickly obtain the required serial number.
