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.

I can't imagine a good reason for doing this.
Why not contact HP and see what they have to say?

... they're probably stolen and they don't want them to be traced. :-0

The only one that I'm aware of that is shown by the BIOS is the CPU's Serial Number which should be switched on By default on all new hardware.
So if you want to change this Serial Number you need to change the CPU as it is encoded into the CPU and can be used to trace the individual computer that it was fitted to originally.
The other numbers are for things like a BIOS String which identifies the Make & Model of the M'Board and changing this would result in someone looking for the wrong Drivers at best and quite likely looking for the wrong thing all together at worst and loading the wrong drivers causing the system to no longer work.
While it is Technically Possible to prevent the BIOS Reporting the CPU Serial Number or even to misreport it that would involve writing a new BIOS Instruction set for every Model or variation of existing models and even resulting in killing the NB's if this was applied to the wrong Model or Revision Numbers. So exactly what is it you want to do here any much more importantly Why do you want or feel the need to do this?
This is something that I would expect from people dealing in Stolen NB's as there is no other reason to attempt this.

Lenovo Specs By Serial Number

I just wanted to point out there are other reasons to need to change a BIOS S/N. We use a utility that records the S/N from the BIOS and adds it to our inventory database. When we replace a mother board, the S/N in the BIOS no longer matches the S/N physically on the device. We need to make those match. Dell has a utilty to accomplish this, but I have yet to find on from HP. There is a section in the HP BIOS named 'Notebook Serial Number' and that is what needs to be changed. I know this is an incredibly old post, but people still find and read this stuff, and no one gave a good answer, they just accused him of stealing the laptops. (He may have, but thats not the topic.)

Since there are local HP resellers in Brazil, importing US product is called a 'gray market' distribution channel.
Since a warranty is valuable, and buying a truckload of stolen laptops in Miami and selling them in Brazil would void the warranty, the guy is most likely doing at least two of these three things:
1) Fencing stolen merchandise
2) Attempting to Defraud HP Corp
3) Attempting to Defraud HP customers in Brazil
4) Competing unfairly with HP Dealers in Brazil
5) Evading taxes and import duties (which is why it costs more to buy it legally).
Other than that, it's perfectly legit....

From what I know, it's a utility called SNZero.exe. It is exclusively internal to HP Service Centers and repair engineers. It is proprietary and not available to the public. If you need to have the S/N changed, you will need to contact HP Support and work with them or an authorized service center to have it changed.
We just had a system board replaced on one of our laptops and the repair tech that came out, used the utility and changed the BIOS S/N all as apart of the warranty call.
