bios password

[Petriooo3]

HP elitebook 845 g10
Hey, so after a drivers and bios update, the laptop was showing an error at boot, saying it was missing some data like serial number, build id, featurebyte, prodid, maybe some other data, and it suggested click Y to input it, 
i clicked Y, and inserted the missing data in the bios menu.
problem is that at the next boot, the error dissapeared but the bios started asking for password, and none of the default passwords seem to work. the pc works normally, windows boots ok, but no access to bios setup.
please provide some solution to this.
