I have a CF-53. While I was in the BIOS, I had loaded the default BIOS settings. After rebooting, I realized my BIOS was now password protected!! WTH?? I called Panasonic Tech Support at 800-527-8675. The tech was VERY knowledgable, and when I explained the situation to him, he said that didn't seem normal and that Panasonic doesn't normally password protect the BIOS. On what seemed purely like a hunch, he suggested typing in "password" - Voila! It worked!!
Thanks Panasonic Dude!!!

The only way to remove the bios password is by removing the CMOS chip and read or swap it with one from another Panasonic CF-53 motherboard. Here is the location of that chip. It is usually has a bit of green or purple paint on it.

    Hello. Same problem here, do you have a 25q128 dump for CF-53 without password?

    I managed to clone the MX25L but the 25Q128A is way harder

SOURCE: panasonic toughbook cf-52 has bios

Welcome to Fixya

Bios password cannot be removed by just reseating the cmos battery. You might need to short the board to reset the bios password. Please take not that this is a critical job you need technical expertise in doing this.

Follow these steps:

  • Remove Laptop Battery
  • Remove Memory Cover
  • Spread spring clips to outside and
  • pull out RAM memory
  • Remove clear vinyl label opposite RAM memory slots
  • In the upper left corner you will see JOPEN1 with a white silkscreen square
Inside the square you will see what looks like the letter T over a U. Using a metal paper clip short the U to the Silver 1/4"post connecting the motherboard to the laptop case and hold it for 25 -30 seconds. Place back your RAM memory, put in the laptop battery and test start laptop. you should see a selection of F1 or F2 for setup. Using the F2 gets you into the Bios menu where you reset the time and date. Then Tab over to the SECURITY setting tab and change your passwords. Then hit F10 key

Thank you for using Fixya!

    Clear / reset BIOS password on a Panasonic Toughbook CF-53


    You can usually reset the BIOS password by unplugging the CMOS battery and all other power sources.
    Then turn the computer on with power plugged in (not the CMOS battery though).
    After computer has booted up, turn off again, plug CMOS battery back in and password should have reset.

    Tutorial on how to do this can be found under soloution 2 of this link:

    Toughbook CF-18 Supervisor Passwd


    Toughbook CF18, CF-18
    How to remove the BIOS Supervisor Password:

    Open all covers and openings. Remove hard drive and battery. Remove bottom of notebook. Many many tiny screws.
    Now look towards the rear of the notebook. You will see 2 plugs both have a red and black wires. The one with the much smaller wires and connector is the BIOS battery. Use a pair of needle nose pliers and remove this plug.

    Leave it off for 5-15 minutes.

    Leave the BIOS battery plug off. Replace the laptop's main battery. Leave the hard drive out. Turn the unit over and turn it on.
    Press F2 when the screen comes up. POOF! NO PASSWORD!

    Go to Security and disable the password. Save configuration. Turn off the notebook. Replace the small connector. Turn it back over and turn it back on. Press F2 and verify that there is no password. Go to Security and Disable the password again. Save the configuration.
    Put the bottom back on. You're done.

    NOW FOR THE BAD NEWS!!!
    Your hard drive is now dead. Replace it. When a supervisor password is used it locks the hard drive to that password. There is NO WAY to recover the hard drive. It is called an ATA security password. Without the ATA password the hard drive is completely useless.
