HP Recommended

Hello,
I bought a used HP EliteBook from eBay (serial: (edited). It has a BIOS Administrator password I don’t know, blocking access.
At boot: “Enter BIOS Administrator Password” screen. After 3 wrong attempts: “System Authentication Failed. Press power button to restart” — no System Disabled code appears.
Need unlock code or steps to reset. Can’t use Fn keys properly due to lock.
Thanks!
