The serial number is a unique code to identify your computer device, to prevent buying fake or counterfeit goods or to use it in case the user wants to find out information from the manufacturer through this serial number. Each laptop will have an individual serial code. In case you need to install a driver or provide information to the warranty staff, you will need this serial number. However, some people do not know how to find the serial number on a laptop, please follow the article below.
Note to users, the methods to check the serial number below may be suitable for different laptop models.
1. Serial number on the camera body and packaging
With some laptop models, we can easily check the serial number right on the camera body, when printed on a small sticker on the bottom of the device. On some other laptop models, this information is printed directly on the device's case. In the case of a removable device battery, the serial number may be printed on a small sticker inside the battery compartment, below the battery.
For desktop computers, we need to find the location on the back, top, or sides of the case. However, we need to open the case because the serial number written on the label may be inside the case
If you still have the original box containing the device, try to find the sticker as the serial number may be written on it.
2. Check the serial number via the CMD command line
If the label is faded and the serial number cannot be seen, there is a very simple way which is to use the CMD command line.
Step 1:
First of all, we are open Run dialog box and then enter the keyword cmd then press OK to access.
Step 2:
At the Command Prompt window interface, users should type the command line below and click OK to access.
wmic bios get serialnumber
Immediately after that, we will see the computer's serial number below the line SerialNumber. This serial number includes both letters and numbers. Additionally, we can also type the command line below to Check the laptop model name in use.
wmic csproduct get name
This command line uses the Windows Management Instrumentation Command-line (WMIC) tool to obtain the computer's serial number from the BIOS on the device.
Note to userswhen we check through the cmd command line, there will be cases where the computer's serial number does not appear. This is the manufacturer's design, so when entering a command, the returned result may be 0 or the message To be filled by OEM as shown below.
This situation will also occur with some self-assembled desktop computers because the computer does not have a serial number.
3. Check the serial number via BIOS
In case the user enters the command on cmd to no avail, they can find the serial number in the BIOS or UEFI firmware installation screen.
Depending on each computer model, the way to access the BIOS will be different. This could be pressing the ESC, F2, F8 or F12 key. Readers should refer to the article Instructions for accessing BIOS on different computer models to learn how to access the BIOS of the computer you are using.
Then we'll get to the section Serial Number in system information in the Main or System screen.

6. Check the serial number through warranty service
If the user has registered the computer with the manufacturer, or used some warranty service, the serial number may be on the warranty service invoice, service confirmation email or billing registration document.
