    I think you need the "open firmware password".

    Power on the Mac and immediately press and hold command-option-P-R. The system will restart with the 'bong' noise; allow it to do this 3 times. On the third 'bong' you can let go of the keys. The machine will now boot with a cleared password and reset PRAM/NVRAM

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

          by traxformania
          Hello,

          I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

          But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

          I'm trying to reset my bios without success.

          I tried :

          -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

          HP Omen 15-dh0052nf power-on & bios password
          by Nopslide
          Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

          My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

          Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

          1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
          2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
          3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...
