ThinkPad™ Password Solutions to recover or clear unknown or forgotten Supervisor Passwords and Repair CRC1 and CRC2 Errors.

Since 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 System Board!

Joe in Australia offers the only Affordable Fully Assembled, Programmed and Tested unlimited use USB based ThinkPad Supervisor Password [SVP] Recovery or Clear Tools in the world. 

It provides the elegant convenience of a dedicated, fully assembled and tested, Ready To Use USB based ThinkPad SVP  Recovery or Clear tool which unlocks an unlimited number of TPs together with detailed illustrated step by step instructions which everyone can understand and follow.

Joe's KeyMaker X1 [KMX1] and X2 [KMX2] can Recover or Clear Supervisor Password from all current IBM and Lenovo ThinkPad models with the exception of the SL300 SL400 SL500 G550 T*40 X*40 X1 Carbon (Gen 2) it can do this even if TPM/TCPA/PC8394T/8356908 security has been enabled

SL300 SL400 SL500 G550 T*40 X*40 X1 Carbon (Gen 2) do NOT store Supervisor Password [SVP] in an EEPROM, that is the reason the SVP cannot be recovered in those models from an EEPROM by KMX1 or KMX2

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 (HDP)

If at any time you see this Password prompt icon

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 or KMX2 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 Password (POP)

The password prompt icon pictured above
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 this 

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.

1. Identify your TP model
   
2. Download 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] 

WARNING:
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 clearing it.

I didn't know there was a Supervisor Password (SVP) set - did the ThinkPad (TP) set one all by itself ?

Lots of TP users are not aware that their TP has a SVP set.

A TP with a SVP set does NOT prompt for the SVP when switched on and is allowed to boot normally.

This is exactly how I got involved in SVP password recovery.

My TP worked perfectly for many months until one day I needed to change a setting in BIOS setup.

It was only when I pressed F1 to enter BIOS setup that a SVP prompt appeared.

If 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.

No, the TP will never set a SVP all by itself, human intervention is always required to set a SVP.

Joe's KeyMaker KMX1 and KMX2 can Recover or Clear Supervisor Password from all current ThinkPad models with the exception of the SL300 SL400 SL500 G550 T*40 X*40 X1 Carbon (Gen 2) it can do this even if TPM/TCPA/PC8394T/8356908  security has been enabled

KMX1 and KMX2 are the latest state of the art innovative ThinkPad SVP unlocking tools from Joe in Australia
