Thank you for the information. Usually, updating the BIOS will force the serial number to appear. For more information on how to do this, please reference this HP document: http://support.hp.com/us-en/document/c00007682

I am also providing a document, regarding your Ethernet connectivity issue (since you stated you can cannot wireless, but not wired): http://support.hp.com/us-en/document/c00818622
