This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds
BIOS/CMOS Password Recovery Tool Service: http://www.biospasswordrecovery.com/

    How on Earth can you use a DOS-based application when you can't even get past the password in order to launch either Windows or DOS? This doesn't make any sense. If someone could go that far, then you could even run Linux from a live CD-ROM or thumbdrive.

The power on password can be removed by simply taking out the CMOS (aka, backup or BIOS) battery at the bottom of the main battery compartment for a minute, re-installing it and then powering up the system. However, if there is a supervisor (aka, BIOS) password also enabled, then while the power on password is eliminated, the BIOS password will kick in and the system will refuse to continue booting until the supervisor password is provided. If you don't know what the supervisor password is, then you are looking at a motherboard replacement (what IBM recommends) or figuring out how to read the stored password out of the system.

Well, if you forgot your bios password, the only thing you can do is reset the CMOS. On a laptop that's not easy to do as it requires you to take it apart, which in turn voids the warranty.
You'll have to take it in to an authorized IBM computer repair shop to have them do it.

HI............
Reset IBM ThinkPad Password
An IBM ThinkPad laptop can have three hardware password sets:
  • Power-On Password
  • Hard Disk Password
  • Supervisor Password
Power-On Password RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if a power-on password is installed, the password bytes are locked and no program can access them.
During power-on password installation, the password (1 to 7 characters) is stored in the security space.
Installing the password is a function of the built-in system program Easy-Setup. The power-on password does not appear on the screen when it is installed, changed, or removed. After the power-on password has been installed, it can be changed or removed only during POST.
Hard Disk Password The hard-disk password (HDP) prevents unauthorized persons from accessing the data on the removable hard disk drive.
Supervisor Password The supervisor password prevents unauthorized persons from changing the system information in Easy-Setup.

How to Reset an IBM ThinkPad Power On Password Using Hardware If the ThinkPad cannot be booted, 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. Press and hold F1 to power on the computer.
  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.

GOOD LUCK......
