How to Reset the BIOS Password on a Panasonic CF-30?

Resetting the password on your Panasonic CF-30 computer BIOS can be accomplished by selecting a very specific option within the BIOS setup program. You must know the password that has been placed on the BIOS to gain access. Once you have accessed this setup program, the entire password resetting process will only take a few minutes.



1. Turn on your Panasonic CF-30. If your computer is already on, restart it.

2. Look for the word "BIOS" listed on screen just below the Panasonic logo during your computer's boot process. Next to the word BIOS will be the label of a keyboard key. Press the key on your keyboard that is listed on screen to load your Panasonic CF-30 BIOS.

3. Highlight "User Password" and hit "Enter."

4. Remove the value listed in the "Password" box on screen. The Panasonic CF-30 did not ship with a password protecting the BIOS, so resetting the password involves removing it entirely.

5. Use the "F10" keyboard key to save the changes you've made to your Panasonic CF-30 BIOS and restart your computer.
