Remove Fujitsu Lifebook Bios Password on Startup

I finally solved my problem after 9hrs :)

I did not know why my BIOS locked up suddenly (I posted the step by step procedure of what I done before this thing happen. see my question)

Laptop Model: Fujitsu Lifebook Bios SH530 (Acquired late 2010)

Fujitsu-Siemens use many different algorithms to calculate master password. But it can be decrypted using the master password hash on wrong password attempts after 3x

Solution:

  • On boot screen Press F2. You must be in Bios Setup Screen which is (Phoenix SecureCore(tm) Setup Utility)
  • Attempt to login using this passwords: "3hqgo3", "jqw534", "0qww294e" (Do not enter again passwords until you get master password)
  • If a Master Password is displayed copy it and use this windows binary script sites.google.com/site/dogber1/blag/pwgen-fsi-5x4dec.zip or using this website bios-pw.org/ Enter the Hash Codes
  • On the Master Password Input Box use the decrypted code if you use the online site use the Fujitsu-Siemens
  • You should be able to access the bios screen and change the settings make sure to remove the Password on Hard Disk and Supervisor Password
  • Use the Decrypted hash code as your current password To Clear the Supervisor Password
