Hi again edb49,
This is straight from IBM's site. Their Maintenance
Manual for the ThinkPad 600X.
"ThinkPad 600X Hardware Maintenance Manual" pgs.7-8
from IBM.com

"Related service information
This section provides information about the following:
"Passwords
As many as three passwords may be needed for any
ThinkPad computers: the power-on password (POP), the
hard disk password (HDP), and the supervisor password
(PAP).
When the power-on password (POP), the hard disk
password (HDP), or the supervisor password (PAP) is
used, the following situations may occur:
If the PAP is used, the HDP is enabled automatically, but
no HDP prompt appears. The HDP is set the same as the
PAP.
. If the POP is the same as the HDP, the POP
prompt appears, but the HDP prompt does not
appear.
. If the POP is not the same as the HDP, both
prompts appear.
If a ThinkPad computer has an extra bay, it can support
more than two HDPs. Then the following situations will
occure:
. If the POP is the same as one of the HDPs (HDP-1
or HDP-2), a POP prompt appears. The passwords
are different.
. If the POP is not the same as either of the HDPs
(HDP-1 or HDP-2), both prompts appear.
. If the PAP is used, the HDP-1 or the HDP-2 is
automatically enabled, but the HDP prompt does not
appear. The HDP-1 or the HDP-2 are then set to the
same password as the PAP.

"Supervisor and hard disk passwords:
The supervisor password (PAP) and the hard disk password
(HDP) are security features that are used to protect the
system and the hard disk data from unauthorized access.
No overriding capability is provided. If only a hard disk
password is set, you must get the password from its owner
in order to run diagnostic tests and perform service. If
both the supervisor password and the hard disk password
are set, you can enter Easy-Setup by pressing the Enter
key or by entering the power-on password at the
supervisor password prompt. In this case, the Password,
Start up, Network, and Initialize or Asset ID (for some
models) icons cannot be selected.
Note: The supervisor password and the hard disk
password cannot be replaced if they are forgotten.
If the customer forgets the supervisor password,
the system board must be replaced. If the
customer forgets the hard disk password, the hard
disk drive must be replaced.
How to remove the power-on passwords:
If only the power-on password is set, do the following to
remove it:
1. Turn off the computer.
2. Remove the DIMM cover from the bottom of the
computer.
3. Short-circuit the two password pads or put the jumper
on the pins.
For the location of the password pads or the jumper,
see "Password pads" on page 68.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not
appear. The power-on password has been removed.
5. Reinstall the DIMM cover.
If both the power-on password and the supervisor
password are set, do the following to remove them:
1. Power on the computer by pressing and holding F1.
2. Enter the supervisor password. The Easy-Setup
menu appears.
3. Click the Password icon.
4. Click the Power on icon.
5. Enter the supervisor password, and press the Space
bar.
6. Press Enter twice.
7. Click Exit; then click Restart.
The power-on password has been removed."
If it is in fact the Supervisor Password it seems
you will have to do more work.
This site offers to recover your password. Yet
your requirement was 'at no cost'. It seems this
person would like $25 to recover the supervisor
password. They did include a method for reading
the chip that contains the PAP. So my thought is,
maybe you can analyze the .bin file this method
produces.
