Thanks for reaching out to Microsoft Community and posting your inquiry.   

The Serial Number of Surface Devices are usually 12-digit numbers. You can also find the Serial Number on your settings. Select Start > Settings > System > About > On this page, find Windows Specifications, and look for your Serial number.

Dear John

I have my serial number, as below:

You can test it again and i am sure you will received invalid serial number, too.

I don't know may my serial number changed from what is written on the back of my laptop? I don’t think so. If you have any other idea, please explain to me.

Thanks.

I have removed the PII for privacy purposes. It could be that you're using the keyboard serial number of the Surface Book. The Surface Book keyboards have separate Serial Numbers from the screen itself.

Look on the bottom edge of the Clipboard where it attaches to the keyboard. You'll need to disconnect the screen from the base. The serial number should be on the connector part.

If the device still turns on, try getting the SN through CMD. Go to the search bar > search for command prompt > right-click then open as administrator > Type this command: wmic bios get serialnumber.

Dear John,

Thanks for your attention.

My device is still working and turn on, So I will check it, as you said. with that Command. I will Back here as soon as i could test your two ways.

I really hope it will answer.

Thanks again and I will say to you, if your suggestions work or not.
