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.
