    Thanks, when i get a chance to get back to it i'll try pulling the cmos battery.



    When i power the laptop the fan comes on and then the screen show many barely visible verticle lines (most in groups).



    i don't get error messages; I can't even get a video output signal to view an external monitor.

Try taking out the cmos memory battery for a hour or two, it works on some laptops, or when you write in 3 wrong passwords do you get a system disabled xxxxx number code?

    sounds like a video adapter failure... so the laptop is not turning on at all?

    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.

    Cf-18 toughbook


    The BIOS may not support the larger drive at all; I suggest you look for a Toughbook forum and repost there and check Panasonic's site for a manual download and possibly a BIOS upgrade if the unit is equipped with a flash BIOS.
