IBM uses a security chip on the motherboard that burns the password into it when a bios password is enabled. The only solution to getting around a bios password on an IBM is to replace the bios security chip or the motherboard. I've wrestled with this before, and believe me when I say it's a whole lot easier to replace the board. Do your best to remember!!!!!!!!

How do i get into bios on a ibm thinkpad 1800/R52? seems like it needs a password. all i want to do is reinstall windows and i cant boot from cd


helo

go to the link below to get further assistance
but basically to reset the password, follow these steps.

If the Power-on password (POP) 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:
  1. Turn off the computer.
  2. Remove the battery pack.
  3. Remove the backup battery (CMOS battery --size of coin- located on mainboard, requires you to remove the plastic cover on rear on computer)
  4. 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.
  5. 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.

Hi I have an ibm thinkpad R52 and recently the batt gave up on me and it took a while before i was able to get it back on. But when i turn it on. The bios is asking for password and i dont know what to do...


To reset the BIOS password read the information from this link.

In case of your IBM laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

My ibm thinkpad r-52 is locked with bios password.how can i remove that .i dont know the password.plz help me mohitagrawal08@gmail.com


Please note that Thinkpad stores the password in a special security chip which is accessed during boot time.

The only option I know to reset BIOS password in a Thinkpad is to disassemble the system and then use the steps mentioned in the following link

I am using IBM R52.. now, i forgot the bios password.. what are all the options to reset the password?...


Thinkpad R52. There is a very good piece of software that you can download from Sourceforge.net. Its a linux software but works very well. Once you download install on a CD. This IBM has the ability to actually store three separate passwords for it's hardware before you get to windows. The toughest being the HDD (hard drive)password. This password is embeded in the boot table and cannot be removed because of the nature of it's function.

Good luck

I need to clear my Bios Password for My IBM Thinkpad R52


OK, I posted this the other day, so for the benefit of those who missed it. "None" of these techniques will work on the R52, as it has a different chip. The above well intentioned solutions mentioned above will work with older models but not this machine as the bios chip has been changed. FYI
