    Can you tell me step boy step how remove the password?
    You need a SPI programmer...extract the content of the bios chip, use the program from post #1, and back to the chip with the new content..watch a video as an example..

    HP Probook 450 G6 here, had a bios password and I was able to dump the bios and use the tool which shows all of the laptops info and said unlocked. Upon writing it back the laptop will only boot to a screen that system locked press enter to restart and it does that over and over.

    One thing I did notice when reading the bios is it gives me two options once it detects it and it will read from both.

    Thoughts?

    Hi! Can somebody unlock this bios for HP Elitebook 830 G8? I couldn't find 16mb chip on board. RCUnlocker doesn't support 32mb. I tried unlock bios by editing RCUnlocker to bypass 32 mb, but result it is not fully correct.

    Thanks to everyone in advance and great thanks to RethoricalCheese for making this possible.
    to understand that you have a bios password and want to delete it??
