All devices, including computers, have a unique identification number that helps manufacturers track ownership and warranty information. While most companies use the term “Serial Number” to refer to this identification, certain manufacturers like Dell and HP use the term “Service Tag”. In this article, we will explore what a system service tag is, why it is important and provide you with four different ways to locate it on your device.
From the Packaging or Stickers
The easiest and most straightforward way to find the system service tag is by checking the packaging of your device, such as the motherboard or laptop. Manufacturers often attach stickers with barcodes to these packages, clearly displaying the service tag or serial number. Additionally, you may find the service tag on the device’s warranty form, which is usually included in the packaging. For laptops, manufacturers often place stickers on the bottom panel, near the model name, where you can easily find this information.
Using Command-line Interface
If you don’t have access to the packaging or stickers, you can use the built-in Command-line Interfaces in your operating system to retrieve the service tag. On Windows, you can use the Command Prompt or PowerShell. In Command Prompt, you can utilize the Windows Management Interface(WMI) class command “WMIC” to retrieve the service tag. Open the Command Prompt, type “wmic bios get serialnumber” and press Enter. The system will display the service tag information if available. In PowerShell, you can use the Common Information Model(CIM) class cmdlet “Get-CimInstance” to obtain the same information. Open PowerShell, type “Get-CimInstance -ClassName Win32_BIOS | Format-List SerialNumber” and press Enter.
Through BIOS or UEFI Settings
Another way to find the serial number or service tag is by accessing the BIOS(Basic Input/Output System) or UEFI(Unified Extensible Firmware Interface) settings. These interfaces provide access to low-level settings and configuration options for your computer’s hardware. To access the BIOS or UEFI settings, power up or restart your computer and press the designated BIOS key repeatedly. This key varies depending on the manufacturer and model of your computer. Once you’re in the BIOS or UEFI settings, navigate to the appropriate section that displays system information, usually labeled as “Main”, “System”, “System Information” or something similar. Look for the service tag or serial number in this section.
Using Official Support Apps or Websites
Many motherboard or laptop manufacturers offer dedicated support applications that can help diagnose issues, update device drivers and provide device information, including the serial number. These applications are often available for download on the manufacturer’s official website. They provide a user-friendly interface where you can easily find the service tag or serial number information. If such applications are not available for your device, you can typically find the serial number through the manufacturer’s official online support website. These websites often provide services or mini-apps that automatically detect your device and display it’s necessary information, including the service tag or serial number.
Conclusion
The system service tag, also known as the serial number, is a unique identifier that allows manufacturers to track ownership and warranty information for devices. By locating the service tag, you can easily access support services, check warranty coverage and obtain important device-specific information. Whether you find the service tag through packaging, command-line interfaces, BIOS or UEFI settings, or official support apps or websites, it is crucial to keep this information handy for any future support or warranty-related needs.
