[bios] What "wmic bios get serialnumber" actually retrieves?

I wonder what sort of serialnumber wmic bios get serialnumber Windows commad actually gives you?

Is it serial number of your motherboard? Documentation is not clear about it.

wmic bios get serialnumber     

if run from a command line (start-run should also do the trick) prints out on screen the Serial Number of the product,
(for example in a toshiba laptop it would print out the serial number of the laptop.
with this serial number you can then identify your laptop model if you need ,from the makers service website-usually..:):)

I had to do exactly that.:):)

run cmd

Enter wmic baseboard get product,version,serialnumber

Press the enter key. The result you see under serial number column is your motherboard serial number
