Reset IBM ThinkPad BIOS 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 only the power-on password is set, do the following to remove the power-on password.
- Power off the computer
- Remove the DIMM cover on the bottom side of the computer.
- Short circuit the two password pads or put a jumper on the contacts to short the circuit.
- 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.
- Reinstall the DIMM cover.
If both the power-on password and the supervisor password are set, do the following to remove the passwords:
- Press and hold F1 to power on the computer.
- Enter the supervisor password. The Easy-Setup menu appears.
- Click the Password icon.
- Click the Power on icon.
- Enter the supervisor password and press the Space bar.
- Press Enter twice.
- Click Exit then click Restart.

thanks in advance…
Have an IBM Thinkpad R32 and the Supervisor Password is enabled inthe BIOS. We want to change the boot order and though we can get into the BIOS, we can not make any changes. We were told to buy another Mobo but this was given to us and we’re at wits end and have no clues as how to disable or remove Supervisor Password. Please help us if at all possible
what is that mean?
Short-circuit the two password pads or put a jumper on the contacts to short the circuit.
you mean the bios battery ?
Can you tell which two password pads? Do you have a picture of this two pads so I make sure which ones you are refering to?
I’ll appreciate your help on this.
I have a thinkpad T500 and forgot the password someone told me to remove the battery and the cmos battery and that would do it…I did that and now I cant get into anything it says the date and time are wrong I put a new hard drive in and that did nothing if I could get to the boot menu I could reinstall OS but I can not bring up anything because it keeps asking for a password. I only had a log on password but now it seems there is some other password that I never intered.
