Power-on password scrambled without notice

[Cuong_Nguyen]

Hi there,

I got 2 separate passwords for my Laptop HP Probook 440 G5, password1 as power-on and password2 as BIOS Administrator.
I set the same password1 as user and password2 as master for my SSD and HDD disks installed on the system.

I used BIOS Administrator password to boot up for years as it requited to be the same as master password for the disks in order to boot up and.

Today I decided to clear passwords and do some BIOS config modifications (i.e. disable Fast Boot feature) So I changed BIOS Administrator to empty. Now it don't ask for BIOS Administrator password anymore, but only POST Power-On Password. But no passwords work at POST Power-On password screen. I still keep my passwords a password  software manager. So all the passwords must be correct. Now my laptop doesn't recognize my POST Power-On password.

I haven't done nothing wrong, but only clear BIOS Administrator password *BEFORE* clear POWER-ON password.

How can I reset BIOS POST Power-On Password?

Thanks & best regards,
