Finding the serial number on Lenovo laptops

If you have a Lenovo laptop, there are several ways to locate its serial number.

Locating the serial number on the bottom of the laptop

The easiest way to find your Lenovo laptop's serial number is to look at the bottom of the device. Many Lenovo laptops have a product label or sticker on the bottom panel that includes the serial number. Flip your laptop over carefully, locate a sticker or label, and find the line labeled "S/N" or "Serial Number".

Checking the BIOS for the serial number

If the sticker is missing or worn out, the serial number can be found in the Basic Input/Output System (BIOS) settings. BIOS is the firmware that runs your computer when it starts up. Follow these steps to find your serial number.

1. Restart your Lenovo laptop, and press the F1 key during startup.
2. Once in the BIOS, look for "System Information" or a similar option. You should find your serial number listed under "Serial Number" or "Product ID."

Finding the serial number on Lenovo desktops

Lenovo desktops also have multiple ways to find the serial number, whether it's on the physical device or through software.

Locating the serial number on the back or side of the desktop

Look on the back or side panel of your Lenovo desktop. A sticker or label should contain the serial number. Check for "S/N" or "Serial Number" to find the exact number.

Checking the BIOS for the serial number

Just like with Lenovo laptops, the BIOS on desktops can also show the serial number.

1. Restart your Lenovo desktop, and press the F1 key during startup.
2. Once in the BIOS, look for "System Information." The serial number will be listed there.

Finding the serial number on Lenovo tablets

For Lenovo tablets, locating the serial number can be just as easy.

Locating the serial number on the back of the tablet

Turn your tablet over, and look for a small label or sticker on the back. Locate "S/N" or "Serial Number" to find the serial number.

Checking the system settings for the serial number

1. Open the Settings app on your Lenovo tablet.
2. Tap About Tablet. The serial number should be listed under "Device Information" or "Status."

Finding the serial number on Lenovo smartphones

If you own a Lenovo smartphone, you can easily find the serial number in the settings or on the device itself.

Locating the serial number in the settings menu

1. Open the Settings app on your Lenovo smartphone.
2. Tap About Phone. The serial number will be listed under "Status" or "Device Information."

Checking the SIM card tray or battery compartment

Some Lenovo smartphones have the serial number printed inside the SIM card tray or battery compartment.

1. Carefully remove the SIM card tray on the side of the phone or open the back cover to access the battery compartment.
2. Look for "S/N" or "Serial Number" printed on the device.

Finding the serial number by using Lenovo Vantage or the Lenovo support website

Lenovo Vantage is a helpful app on your computer that can quickly display your device's serial number.

1. Open Lenovo Vantage from your Start menu or download and install it from the Microsoft Store if you haven’t already.
2. Go to the “Device” section. The serial number will be displayed under "Device Details."

Alternatively, you can use the Lenovo Support website. Hover over PC in the navigation bar and select Detect Product. The site will find your product and display the serial number.
