Remove Fujitsu Lifebook Bios Password on Startup

Question

I Tried to remove the Boot up Bios password in a Fujitsu Lifebook Bios SH530 Model. But it still asking for password on bootup and now may password did not work. Can anybody help me? Here's what I did:

1. Press F12 on Bootup
2. Sign in using the old password
3. Go to Security Settings Tab
4. Change the Boot up Password by Typing in the Current Password and leaving the New Password Inputbox Blank. I just press enter 2x.
5. exit the bios screen and save settings
6. <-- The Worst next time I Boot up it still ask for password but my old password did not work. I tried just leaving it blank and press enter but it is Invalid! I tried 3x and wooops a non stop long beepp sounded with SYSTEM DISABLED on screen no Hash code or what so ever.

What did I do Wrong? Do anyone have this experience? What did you do to solve this problem?

PS. I do not know the supervisor password for it.

UPDATE:

• It seems the Master Password will only show up on boot before loading windows 7. If will not show up on Bios Settings. I'm currently using this page to decrypt the hash code http://bios-pw.org/

• My question now is how do you display the Master Password Hash in Bios Setup? If I can get it I can decrypt it and hopefully remove the password.

Answer 1

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
