You would go to the
HP Support Page for your laptop model to check for updates.
As it turns out, there are updates for your system, but I would ask why you are considering updating the BIOS? This should ONLY be undertaken if:
1) You are experiencing some sort of compatibility issue
2) The BIOS description specifically states it resolves the issue you are experiencing.
If both conditions above do not apply, then do not attempt to update the BIOS.
