The Challenge of Hardware Identification
When you need to update your system BIOS, download chipset drivers, or process a warranty claim, you must know the exact make, model, and serial number of your motherboard (also known as a baseboard). If you built a custom PC, you might have thrown the original box away. If you bought a pre-built machine from a manufacturer like Dell or HP, opening the case to physically hunt for a tiny barcode sticker is frustrating and sometimes voids the warranty.
Fortunately, Windows 11 stores this hardware information deeply within its management instrumentation. By using the powerful wmic (Windows Management Instrumentation Command-line) utility in the Command Prompt, you can extract the exact serial number in seconds without opening your computer case.
Step 1: Open the Command Prompt
You do not necessarily need Administrator privileges to query basic hardware information, but it is always best practice when dealing with WMI commands.
- Press the Windows Key on your keyboard.
- Type
cmd. - Right-click on Command Prompt and select Run as administrator.
Step 2: Use the wmic baseboard Command
In the Windows Management Instrumentation structure, the motherboard is officially referred to as the “baseboard”. You need to tell the wmic tool to query the baseboard class and return specific values.
Type the following command exactly as written and press Enter:
wmic baseboard get product,Manufacturer,version,serialnumber
Breaking down the command:
- wmic baseboard: Instructs the command line to target the motherboard hardware class.
- get: Tells the tool to retrieve data rather than set it.
- product,Manufacturer,version,serialnumber: These are the specific data fields you are requesting. Note that there are no spaces between the words and the commas.
Step 3: Analyze the Output
Within a second, the Command Prompt will output a neatly formatted table containing four columns.
- Manufacturer: The company that built the board (e.g., ASUSTeK COMPUTER INC, Gigabyte, Dell Inc).
- Product: The exact model number (e.g., ROG STRIX B550-F GAMING or 0K32JM). This is what you need to search for on the manufacturer’s website to find BIOS updates.
- SerialNumber: The unique alphanumeric barcode assigned to your specific board. You will need this if you ever contact customer support for an RMA (Return Merchandise Authorization).
- Version: The hardware revision of the board (often useful if a manufacturer released two slightly different physical versions of the same product).
Troubleshooting “To Be Filled By O.E.M.”
Occasionally, you may run this command and see “To be filled by O.E.M.” instead of a serial number. This happens when the Original Equipment Manufacturer (like a boutique PC builder or a budget laptop brand) physically forgot or chose not to flash the serial number data into the motherboard’s firmware at the factory.
If the WMI command cannot read the serial number because it is missing from the firmware, no software tool in Windows will be able to find it. In this rare scenario, your only option is to open the computer case and look for a physical sticker on the motherboard itself.
