    X280 NM-B521 bios no display

    Hello,
    I used HP Unlock tool to remove my bios password but i think it doest work correctly.

    Step followed :

    1. Unsold the W25Q256JVEN Chip
    2. Dump memory
    3. Drag and Drop to HP_unlocker.exe
    4. I have written to memory the new file
    5. Solder the memory to the motherboard
    6. Start the computer and i will try to enter in the setup bios menu. At this moment i have loading bar "repair..."
    7. Windows startup
    8. i restart the computer and i'm trying to go again in the bios setup but the password is always set.

    Anyone can help me please ?
    Maybe it's HP Wolf security ? or a software who run a script on windows startup ?

    Use RC unlocker , don't use HP unlocker.
