    Then i found out multiple 2 more nvram so i replaced the second one with FF. wrote it back and now the laptop doesn;t turn on. tried to put the original backup file.. still doesn;t work.
    Tried to use the rcunlocker but its asking for 16mb but mine is 32 which one user said you have to split it 2 use the rcunlocker and combine it back but i don;t know to to split in two(maybe someone can eli5 this step)

      No, same issue, power led and capslock power on for 1-3 seconds then turn off. I read the chip>erase>write>verify all pass. Any suggestions?

      many thanks.

              Seeking help and advice to remove bios admin password – HP ProBook 4520s
              by Phad
              Dear All,

              Hope that this post is at the right place of the forum.

              I am seeking help and technical advice to remove bios admin password from HP ProBook 4520s.

              The laptop is operating normally and, I am not facing any major issue with it except; the bios admin password that I found about by coincidence only few weeks back.

              As the laptop is operating normally, I am reluctant to take it to a workshop to de-solder the bios chip in order to read it by an external programmer, as I am not an expert in doing such a thing.

              After...

              [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,...
