A backdoor BIOS password is a security code that was assigned to your Panasonic Toughbook Cf-29 laptop computer during its original assembly. Though users can set a BIOS password if they'd like, this backdoor password will always override it and allow users to enter the BIOS. The backdoor password never changes, and can be used to unlock your Toughbook BIOS in the event that you can't remember your user-specified password.

Press "Power" to turn on your Panasonic Toughbook Cf-29.

Press "F2" on your keyboard when you see the Panasonic logo appear on the screen. You will immediately be prompted to enter your Panasonic Toughbook Cf-29 BIOS password.

Type the word "Biostar" into the password prompt. This is your Panasonic Toughbook Cf-29 backdoor BIOS password. Press the "Enter" key to unlock your Panasonic Toughbook Cf-29 BIOS.
