How to Find the Serial Number of a Laptop?

When it comes to dealing with technical issues or seeking support for your laptop, knowing its serial number can be extremely helpful. The serial number is a unique identifier that distinguishes your device from others, and it is often required for tasks such as warranty claims, software registration, or troubleshooting. In this article, we will guide you through various methods to find the serial number of your laptop. So, let’s get started!

Method 1: Check the Sticker on the Laptop

The easiest way to find the serial number of your laptop is by checking the sticker placed on the device itself. Laptop manufacturers usually affix this sticker on the bottom of the laptop or inside the battery compartment. Look for a combination of numbers and letters labeled as “Serial Number,” “S/N,” or “SN.” Once you find it, make a note of the serial number for future reference.

Method 2: Check the BIOS or UEFI Settings

If the sticker on your laptop is worn out or difficult to access, you can also find the serial number within the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) settings. The BIOS/UEFI is a firmware responsible for initializing hardware components during the boot-up process. Here’s how you can retrieve the serial number from the BIOS/UEFI:

1. Restart your laptop and access the BIOS/UEFI settings by pressing a specific key during the boot process. The key may vary depending on the laptop manufacturer and model. Common keys include F2, F10, Delete, or Esc. Refer to your laptop’s user manual if you are unsure about the correct key.
2. Once you enter the BIOS/UEFI settings, navigate through the menus using the arrow keys. Look for a section that provides information about your laptop’s hardware or system information.
3. Within this section, you should find the serial number listed alongside other details such as the model number and BIOS version. Take note of the serial number and exit the BIOS/UEFI settings.

Method 3: Use the Command Prompt or PowerShell

If you prefer using the command line interface, you can find the serial number of your laptop using the Command Prompt or PowerShell on Windows. Follow these steps:

1. Open the Command Prompt or PowerShell by pressing the Windows key + X and selecting the desired option from the menu.
2. In the Command Prompt or PowerShell window, type the following command and press Enter: wmic bios get serialnumber
3. After executing the command, your laptop’s serial number should be displayed on the screen. Make sure to record it accurately for future reference.

Method 4: Check the System Information Utility

The System Information utility, a built-in tool in Windows, provides detailed information about your laptop’s hardware and software configuration, including the serial number. Here’s how you can access it:

1. Press the Windows key + R to open the Run dialog box.
2. Type “msinfo32” in the text field and click OK. The System Information window will appear.
3. In the System Information window, locate the “System Summary” section. You will find the serial number listed as “System Serial Number” or “Serial Number” within this section.

Method 5: Look for the Serial Number on Packaging or Documentation

If you still can’t find the serial number using the methods mentioned earlier, consider checking the laptop’s packaging or any accompanying documentation. Laptop manufacturers often print the serial number on the box or provide it in the user manual or warranty card. Be sure to keep these documents safe for future reference.

Method 6: Contact the Manufacturer or Retailer

In case you exhaust all the options mentioned above and are unable to locate the serial number, don’t worry. You can always contact the laptop manufacturer or the retailer from whom you purchased the device. Provide them with the necessary details, such as the laptop’s model number and any relevant purchase information, and they should be able to assist you in retrieving the serial number.

In conclusion, finding the serial number of a laptop is crucial for various administrative and technical purposes. By following the methods outlined in this article, you can easily access this vital information. Whether you check the sticker on the laptop, delve into the BIOS/UEFI settings, utilize the Command Prompt or PowerShell, access the System Information utility, look for packaging/documentation, or seek assistance from the manufacturer or retailer, you will undoubtedly find the serial number you need.
