Please, read the Community TKB article about this and follow the steps >> https://h30434.www3.hp.com/t5/Notebooks-Knowledge-Base/Forgotten-or-unknown-password-Can-HP-help-me-...
This is related to BIOS/UEFI password. If related to a laptop, HP can remove BIOS and power on passwords via a service of the computer. You can contact HP Support to set this up. Options vary depending on location and warranty status (Service fee may apply).
