Top 3 methods to crack supervisor password!

Hi,

The IBM Thinkpad has a very strong security system.

If you are seeing a lock symbol when booting then somebody has set the supervisor password. If you can't remember it or guess it (try "password", "admin", "pass", etc) then you need to find the person that set the supervisor password.

Once the supervisor password is set the T41 is very well protected and it can't be reset by removing the laptop battery or CMOS battery.

There is a way to read the password from the protection chip but this is very complicated and requires taking the laptop apart and building your own chip reader.

The instructions for doing this are are:

Hope this helps,

Hard Disk Password

The hard-disk password (HDP) protects the data on your removable hard disk drive from being accessed by unauthorized persons.
Supervisor Password

The supervisor password protects the system information in Easy-Setup from being changed by unauthorized persons.
How to Reset an IBM ThinkPad Power On Password using Software

If you can boot the IBM ThinkPad, KeyMaker will recover the BIOS password.
How to Reset an IBM ThinkPad Power On Password Using Hardware

If you cannot boot the ThinkPad, you will have to reset the IBM ThinkPad password via hardware.

If only the power-on password is set, do the following to remove the power-on password.

1. Power off the computer
2. Remove the DIMM cover on the bottom side of the computer.
3. Short-circuit the two password pads or put a jumper on the contacts to short the circuit.
4. Under the short-circuit condition, power on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The power-on password is removed.
5. Reinstall the DIMM cover.

If both the power-on password and the supervisor password are set, do the following to remove the passwords:

1. Power on the computer by pressing and holding F1.
2. Enter the supervisor password. The Easy-Setup menu appears.
3. Click on the Password icon.
4. Click on the Power on icon.
5. Enter the supervisor password and press the Space bar.
6. Press Enter twice.
7. Click on Exit; then click on Restart.

A Supervisor password protects the system information stored in the BIOS. The user must enter the Supervisor password in order to get access to the ThinkPad BIOS Setup Utility in order to change the system configuration. If the Supervisor password is forgotten there is no way to reset it to enter the BIOS configuration. Setting a Supervisor password automatically sets the master Hard drive password. The following is the icon that comes up in the upper left corner if a Supervisor password is set:
A forgotten Supervisor password will prevent access to the ThinkPad BIOS setup utility. To regain access, the system will need to be serviced to have the system board and hard drive replaced. Proof of purchase is required, and this repair is not covered under the warranty.

Im presuming we are talking about the Supervisor Password. (Screen boots to a lock symbol) If so im afraid that there is not a reset jumper as the password is stored on a chip.

To read the chip to get the password would require major 'surgery' on the laptop.

Im not aware of any other soloution to this issue.
