ThinkPad™ Password Solutions to recover
or clear unknown or forgotten Supervisor Passwords and Repair CRC1 and CRC2 Errors.
early 2002 this
site has been dedicated to ThinkPad™ (TP) owners who find themselves locked
out for whatever reason, they may not know the Power On Password (POP) or Supervisor
Password (SVP) or Hard Disk Password (HDP) or encounter a BAD CRC1 or CRC2 ERROR
on their TP.
TP owners will have subsequently discovered, to their absolute amazement,
that the manufacturer of their beloved TP offers no economically
viable solution. The manufacturer does not have a policy to help genuine legitimate owners
out of this predicament without paying, in some cases more than the TP is
worth, to replace for no sane or logical reason their perfect and fully functional

Most people are absolutely certain they have a
Supervisor Password (SVP) set .
There is a chance you may not have
a SVP set in your TP.
I have exchanged emails with many
people who have gone through all the SVP unlocking thing read the
EEPROM, wasted days, only to discover there is no SVP set at all.
How is that possible, are these people really dumb or
The answer is NO, these are all perfectly sane
The real problem is IBM/Lenovo and their warped sense
When you really do have strong security, you challenge
people to try and defeat it, you invite peer review to make sure
it is in fact secure.
When you have flimsy security and obstinately pretend
it is so secure even the manufacturer cant unlock it, well you have to
get all secretive and vague about it all praying customers wont find
out, in other words an illusion of strong security which is what we have
Clearing a Supervisor Password (SVP)
from a TP is fairly straightforward.
Once you know how to avoid all the
TRAPS IBM/Lenovo have set for you the customer.
Trap number 1, the Hard Disk Password
If at any time you see this Password
That icon with the small number 1 (it
may be a small number 2 or 3 if you have more than one Hard Disk]
means the HDP is set. You will not be able to easily recover or clear
the HDP, KMX1 will NOT recover or clear HDP.
It will cost you more to clear the HDP
than a new reliable Hard disk with warranty is worth.
Clearing a HDP is only worth the
expense and effort if there is valuable data on the Hard disk that
MUST be recovered.
If HDP is set then
remove the Hard Disk [HD] before continuing so that you can determine
which other passwords (IF ANY) you need to recover or clear.
There may not be any other password set!
Ok, you removed the HD and you see yet another
Password Prompt icon.
Trap number 2, the guessing game - is it SVP
or POP -
The trap is that IBM/Lenovo in their wisdom chose to
have THE SAME PASSWORD PROMPT ICON for BOTH SVP and Power on
The password prompt icon pictured
Does NOT define which PASSWORD it is asking you to enter.
It can be either POP or SVP
Note: On some Lenovo ThinkPad models
under some circumstances a Supervisor Password prompt icon looks like
I have only seen this distinctive SVP
icon on one ThinkPad, so it is RARE for now, almost all ThinkPads to
date use the same icon to prompt for POP and SVP.
Only ONE way to find out for sure
which one it is and maybe save a LOT of time.
your TP model
the Hardware Maintenance Manual (HMM) for your TP model
Spend the time to read the first part of the HMM
which deals with Cautions some of which like for example Shock Sensors
are very important, you would not want to roughly handle your System
board to find out when you power it up to unlock it that in fact you
have ruined it.
Read the HMM section dealing with Passwords and
become familiar with how to remove Power on Password [POP]
If you have a ThinkPad that can
boot even though it has a Supervisor Password set
Removing Power On Password [POP]
will render it unbootable Until the Supervisor Password is removed AND
the correct Date and TIME are set in BIOS setup
Having first READ AND UNDERSTOOD THE WARNING ABOVE
YOU DECIDE if you will follow the instructions for POP Removal
NOTE - IMPORTANT - make sure you
do read this !!
The instructions in the IBM/Lenovo HMM regarding
POP removal are easily misunderstood.
The CMOS backup battery [small single cell lithium
battery, usually yellow colour] must be disconnected.
Main battery MUST be removed.
AC Adaptor MUST be unplugged from the ThinkPad.
In other words the ThinkPad must have
absolutely no electrical power, no CMOS battery - no main battery -
no AC adaptor connected.
Then with NO ELECTRICAL POWER at all to the
ThinkPad WAIT A FEW MINUTES just to be on the safe side.
Confirm that POP has in fact been removed;
After POP removal, connect the CMOS battery,
install the Main battery, connect the AC adaptor.
Switch the ThinkPad ON and you should see an ERROR
MESSAGE about Date and Time needing to be set.
That error message is your confirmation
of a successful POP removal.
That is NOT a real error, it simply means that
once you can go into BIOS setup you need to set the correct Date and
Time, so it is not something that is of real concern, nothing is
wrong, this is normal.
If you do not see an error message that means
that you DID NOT reset POP. Main reason is usually that you have
not removed ALL POWER from the ThinkPad, read the "NOTE -
IMPORTANT" paragraph above and try POP removal again.
After performing POP Removal
if there is no password prompt icon displayed, you
are done, your TP is unlocked, go to BIOS setup by pressing F1 when
switching ON [press ESC key to continue past the error message] and
set Date and Time then press F10 to save.
if you have performed POP Removal and
you continue to see this password prompt icon
It does NOT mean you didn't
perform POP Removal correctly
It means that with
POP removed, you have now absolutely confirmed that you do indeed have
a SVP set and you can now put the time and effort into removing or
didn't know there was a Supervisor Password (SVP) set - did the ThinkPad
(TP) set one all by itself ?
of TP users are not aware that their TP has a SVP set.
TP with a SVP set does NOT prompt for the SVP when switched on and is
allowed to boot normally.
is exactly how I got involved in SVP password recovery.
TP worked perfectly for many months until one day I needed to change a
setting in BIOS setup.
was only when I pressed F1 to enter BIOS setup that a SVP prompt
the CMOS battery goes flat or is disconnected for even a very brief
period the Date and Time are reset, next time the TP is switched on it
absolutely insists that you go to BIOS setup in order to set the correct
Date and time, if there was a SVP set [even though you had no idea a SVP
was already set] then it prompts for the SVP.
the TP will never set a SVP all by itself, human intervention is always
required to set a SVP.
