    HP Probook 4520s Administrator password reset

    Hi,
    got HP Probook 4520s laptop. Works ok, but can't enter bios because it asks Administrator password. Boot from HDD or USB is allowed.

    Tried:

    HPBR - Result: Not supported notebook
    FPTW - Can dump but no re-flash... (Error 280 Failed to disable write protection for the BIOS space)
    SMC.BIN (HP no longer creates these files)
    Short Method: https://superuser.com/questions/1108...30s-reset-bios (Not worked)
    RCUnlocker (Created unlocked file from bios dump but can't flash with FPTW (error 280)

    I don't have hardware / SPI flasher.. Anyone can help? Is it maybe possible reset admin password another way?

    Product number: WT152EA#UUW
    Serial Number: 2CE0380ZRD
    UUID: 2EDCE21E25C7DF11BD47E080B300006F

          ā€œHP ProBook 11 G2 BIOS password reset request ā€“ Need SMC.bin
          by Soumana Sanou
          Hello,šŸ˜‡šŸ˜‡šŸ˜‡
          I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

          šŸ”§ Model: HP ProBook 11 G2
          šŸ“¦ Serial Number: 8CG72478MY
          šŸ†” UUID: 6F5ED686-5532-11E7-A2E2-911C6404E011
          šŸ”’ BIOS Status: Locked with password

          The laptop is no longer under warranty and HP refused to help me.
          Iā€™m looking for a custom SMC.bin file.

          I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.

          Thanks a lot for your help!šŸ™šŸ™šŸ™...

          BIOS password reset for HP ProOne 440 G9
          by ch.wa
          HI,

          I have a problem with the BIOS password for the HP ProOne 440 G9 (AIO). Once I want to enter the BIOS a password is requested (see screenshot) and I am a little unsure if it would be smart to try a wrong password three times (as some people mentioned online) to get a code - I don't want to block the whole system (not sure if that could happen?!). According to other sources a reset is (maybe) not even possible for this model.

          Any ideas if this may work? Hope someone could help.

          Thanks for your time!
          Chris
