    How can I extract the current BIOS (bin) from my HP Probook 640 G2 to be able to post it in this forum and have it unlocked for me? When I get it I'll ask how to load the unlocked BIOS. Thanks in advance.

    I don't have an eeprom reader. Is there a way, using some application or software tool, to extract the current BIOS from Windows, for example? I have normal access to the Laptop and can boot Windows.
