How can I fix the serial number and the product number in my bios cq61-410us?

I have a laptop HP 18 months, with Windows 7.  It worked wonderfully in all until he decided a little there is to lose the serial number on the bios information.  Thus, he thinks now that I have a copy of counterfeit Windows.  How can I restore the serial number and product number in the bios information?

Hello

The only practical way to achieve this is to contact HP via the corresponding link below and to make arrangements for this information re-tattooed to the bios to a service center authorized.

If you live in the United States, contact HP here.

If you are in another part of the world, begin here.

Kind regards
