The only way to clear BIOS password is to read it first from the chip and then change it.
Removing batteries does not help.

Ibm thinpad t40 is locked unable to open


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......

This ThinkPad id locked with a POWER ON PASSWORD, this is diffucult to remove and there are no back door passwords you can use to unlock this computer.
There is a way to remove this password, but it rquires building an EEPROM reader and attaching it to your ThinkPad. For details please click on this link :-

My laptop IBM Lenovo Thinkpad T60 of type:2008-AD7, S/N L3-C0670 06/07, seems to be locked at the very start when the power is turned on, it shows a lock and enquires a password from the early start. it...


Hi,

There is no default password on the T60.

If you are seeing a lock symbol then somebody has set the supervisor password. If you can't 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 T60 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,

Just as i turn the power on it says date time error then goes to a black screen and asks for a password ibm r51e


HMM, your kind of screwed I have worked on the thinkpads in my shop b4 and there is no work around the bios password. Either you need to remember your password or get ahold of who you bought it from. IBM has a military contract and they are not allowed to set a backdoor on the thinkpads according to that contract. The only thing they can do is replace the motherboard its a crock but thats the way it is. I would just but buy a new laptop that motherboard is $249 plus labor.

Dont have password


There are two sections (that come to mind) when a password is requested in starting a computer. BIOS or Windows Passwords.
WINDOWS PASSWORD This will be after the windows logo as come up. Depending on which version of windows you have, you will need to find a windows password reset tool. 
A lot of these will require you to boot from a CD that you have created from an ISO image. If this is is confusing, head into a computer shop and ask them to do it.  Alternatively, reformatting the machine by reinstalling windows over the top should eliminate the problem (and all of the data that is still on the machine.)
BIOS PASSWORD This will usually be during the 'black screen' phase of booting.
An IBM ThinkPad laptop can have three BIOS hardware passwords set
  • 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 cannot be accessed by any program. 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) 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.

What is the default password for my R51 Thinkpad by IBM Model # 2888?

The Power On Password problem is near impossible to crack. It is designed to prevent unauthorized access to the Thinkpad and removing the BIOS battery will not remove the password because the password is stored on an EEPROM chip.
There are no backdoor passwords available, the only option is to ask the person who set the password.
OR
There is a way to hack into the Thinkpad to see and remove the password but it requires electronic skills, a program and a working computer.

ThinkPad G40 is locked up


Oops, straight from the manual for your laptop...

Problem: I forgot my password.
Solution: If you forgot your power-on password, you must take your computer to an IBM reseller or marketing representative to have the password canceled. If you forgot your hard disk password, IBM will not reset your password or recover data from the hard disk. You must take your computer to an IBM reseller or an IBM marketing representative to have the hard disk drive
replaced. Proof of purchase is required, and a fee will be charged for parts and service. If you forgot your supervisor password, IBM will not reset your password. You must take your computer to an IBM reseller or IBM marketing representative to have the system board replaced. Proof of purchase is required, and a fee will be charged for parts and service.

Sorry to see that... Good luck.

Power-on password problem!


The power on password is stored on an EEPROM chip and removing the BIOS/CMOS battery won't help.
You need to read the EEPROM chip to get the password.

This works great
Forgotten Power-on password
If the Power-on password is forgotten
and the Supervisor password is known,
simply go into the ThinkPad BIOS setup
utility and reset the Power-on password,
otherwise try the following:
Turn off the computer.
Remove the battery pack.
Remove the backup battery. This is
located under the battery.
Turn on the computer and wait until the
POST ends. After the POST ends, the
password prompt does not appear. The POP
has been removed.
Reinstall the backup battery and the
battery pack.
Note: Some ThinkPad systems have the
ability to reset the Power-on passwords
in the ThinkPad BIOS setup utility if a
Supervisor password has been set.
