How to get BIOS serialnumber with WMIC command

command-line bios wmic

So how can I get the BIOS Serial with that problem.

You do not. You already provided your own answer, however the hardware you have has no serial number. People either did not set one at manufacture, or they forgot about it.

This is sadly quite common.

Whenever I use the command line below

wmic bios get serialnumber

It outputs the BIOS Serial number with my laptop.

However, I've tried that command line to get BIOS serial number with my company's PC, I didn't work a bit.

Here was the output:
```
C:\Users\companypc>wmic bios get serialnumber
SerialNumber
System Serial Number
```
So how can I get the BIOS Serial with that problem...

  It may be that the serial number of the computer isn't saved in the BIOS the same way as your personal computer. You may need to try something like CPU-Z or similar to gather hardware information.

  @MichaelFrank: That's great. However, I am looking for the command line or any way which can output the BIOS Serial number to me.

  In that case, what is the make/model of the work PC?

  In that case, it looks either there isn't any information on your computer programmed in, or you don't have the correct permission to view it. Try running msinfo32, and on the first page see if there is anything listed under System .... Again, what is the make/model of this PC? Is it OEM, or prebuilt.

  Most likely, this isn't a brand name computer and nobody ever assigned it a serial number.

  @DavidSchwartz: So in this case that, I need to assign a serial number for that or how can I do now?

  @PMay1903 You'll have to follow the directions provided by the manufacturer of the motherboard. Usually they provide a tool to allow system builders to assign a serial number.

  @DavidSchwartz: This PC was installed and assigned for me and I am so surprise about that because it doesn't have the BIOS serial number even it's a new one with core i5.

  A computer will only have a serial number if the company that made/built it decided it needed one. If it isn't a mass produced model it simply won't need a serial number as there isn't many reasons to identify the computer as one complete unit. The individual components will likely have separate warranties with their respective manufacturers.

  @PMay1903 Who made the computer?

  @MichaelFrank: Thank you for your explanation. Hence, in this case, it doesn't have the BIOS serial number as separated component. As a result of this, does it allow to me to set serial for that or not? If it's not, please tell me why? Furthermore, is it impossible if I remove the BIOS serial number with my laptop which has been set by its manufacturer?

  @DavidSchwartz: The IT HelpDesk made that PC for me. It has been built and installed already.

  @PMay1903 If the IT desk made this PC for you, does it have a company asset tag? That would be the closest thing you'd get to a serial number on a custom made PC.

Is it impossible if I try to remove my BIOS Serial number with my laptop?

Yes and no. There is a field for the serial number (and other fields for much more information) in many generic BIOSes and methods to read these fields. The person manufacturing the BIOS should fill this with the correct information. Unless that is done the fields often read their default values (e.g. "insert manufacturers name here" rather than the proper name. Or "serial number: 000000" etc etc.)

Sometimes this is a driver issue! Installing the mainboard drivers may resolve the issue and suddenly WMI can query the serial number.
