• Launch the Configuration Manager console.
• Go to Assets and Compliance\Overview\Devices.
• Right-click a device and select Start CMPivot.
• In the query window, enter “Bios | project SerialNumber” to get the serial number of the computer.

The CMPivot query Bios | project SerialNumber retrieves the Serial Number of the given computer.

Let me share another useful CMPivot query with which you can find the computer name using the serial number. The CMPivot query listed below can be used to discover the computer name for any given computer if you know its serial number.

Method 4: Find Serial Number of Computer using VB Script

Another way to get the serial number of your computer is by running a simple VB script. The VB script listed below should be saved to a file with .vbs as extension.

Note: The below VB script works only on physical laptops and computers. The script doesn’t work on Virtual machines.

Dim strComputer
strComputer = InputBox("Enter the name of the computer:")
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colSMBIOS = objWMIService.ExecQuery ("Select * from Win32_SystemEnclosure")
For Each objSMBIOS in colSMBIOS
MsgBox strComputer & ": " & objSMBIOS.SerialNumber
Next

Launch the command prompt as an administrator and run the above VB script as illustrated in the below screenshot. After you run the script, enter the computer name in the pop-up box and click OK. The output now shows the PC name along with the serial number of the computer.

Method 5: Locate the Computer Serial Number in BIOS

The serial number for any laptop manufactured by Dell, HP, or any well-known manufacturer should be listed in the BIOS. The BIOS or UEFI firmware settings screen is where you may discover the serial number.

When your computer is not booting up correctly, the serial number can be retrieved from the BIOS easily. However, in some businesses, the BIOS is password-protected for security reasons and users are unaware of this password. By doing this, the laptop is protected from illegal access. Therefore, you can always use the WMI command or other methods to find the serial number if you don’t have access to the BIOS.
