Panasonic toughbook cf-52 has bios password cd-drive does not boot need password removed. cmos battery removal does not work???

only Panasonic.com can clear BIOS admin PW..

not legal here.

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.

You're welcome Juan.

I believe you can reset the BIOS password, (To None, or one you wish. At this stage of the game you may wish to NOT have a BIOS password,. anymore ;)

All you have to do is remove the RTC Battery (CMOS battery), and then press the Power On button in for 10 seconds.

Yes, I know it's in Japanese, but the photos are what is needed.
Go to the 24th photo down.
See that Yellow object with the Red, and Black wires coming from it, and the White plug at the end of the wires?

Just a basic example not installed,

Do not have a direct Service Manual, but maybe these manuals will help,

Try typing "Biostar" in as the password. If that doesn't work, we have another option.
The first step would be to try removing the CMOS battery (the coin shaped battery inside the computer that keeps the clock working). Disconnect the laptop from any power source (AC adapter), and remove the main laptop battery. Third, you will have to remove the bottom plate of the Toughbook. Search YouTube for a disassembly video for your model of tough book. Once you've removed the bottom plate, you should be able to see the internal components. Connected to the system board by two wires will be the CMOS battery. After disconnecting the CMOS battery (carefully!), hold down the power button on the laptop for about ten seconds, then let the computer sit for a few minutes to ensure that it is completely devoid of power. You will then need to reinstall the laptop battery (the main, brick-shaped one — not the CMOS) and boot up the laptop. If all goes according to plan, you should be able to access the BIOS and turn off or remove the bios password. Now you can reassemble your Toughbook. Power off, remove the battery, reconnect the CMOS battery, and reattach the rear plate, and you're good to go!

Its in the motherboard.... remove the c-mos battery and then place it again...it will reset the bios password..

If you remove the CMOS battery for about 30 seconds, replace it, and boot the system. Password should now be gone.

if you are able to open motherboard then simply remove CMOS bettry for 10 sec and put again then password will reset...if you dont open motherboard then ask me?????

remove the bios battery for 10 minutes
