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

It should be noted here,that good intentions aside...none of these techniques will work with the R52, as it does not have the ATMEL 24RF08 bios chip. There are a few companies out there that claim to have the answer to this but you should be skeptical. The only one I've heard of that seems to be legit is www.allservice.ro, I would recommend going to their forums section and doing some further research if youhave this model.

    OK...apparently someone missed my previous answers. The IBM R52 has "NO" password pads etc...The only way I have heard of is either send the thing back to IBM or try the website I referred to earlier. I know this because my company got 40 of these models used from a state auction. The only way to get a system to work is to ghost a copy of the original (which we fortunately had) and let the customers know that when they bought one they must had to purchase a legit XP key from MS. Sorry guys...sux, but at least its the truth.

Hello,

first of all you can't remove a laptop bios password only by removing bios battery or clearing some user informations. This is because as opposed to desktop computers (where this solution might work) laptops have greater security level and store bios informations in a non volatile NAND memory similar to SD or other types of memory cards. These information woun't be deleted if power is cut off.

There are 2 ways to solve the problem. One would be to send the laptop to a service center in order to have it's bios information reflashed (rewritten). The other one is a bit more complicated but may work in your case. You need to "fool" the bios chip to think your hardware configuration has changed and produse a "bios checksum error" in order to have it's user memory deleted. To have this done, you need to remove the main baterry, charger and other things attached to the laptop. Then you need to dissasemble the back side in order to get acces to the main board and the bios chip itself.
You must identify the bios chip, it's a small sqare like chip, probably placed in a socket. You should find a backup battery for it, you need to disconnect it. Locate the ram board and also remove it.
Then, using a sharp metal object, shortcircuit the first 2 pins and the last 2 pins on each side of the square chip. Ex. first 2 pins togheter, last 2 pins togheter and so on. Do this for each side. You should have 8 pin groups to short circuit. After you finish this, connect the laptop's main battery and repeat the procedure with the bios chip (carefull this time not to short circuit other components, you are working with power connected from the battery). Then remove the battery again, reconnect all the components and check to see if this works.

If this fails the only thing left to do is a service center repair. Hope you have luck with this procedure and please ask for clarification if you require any.

Good luck,
Bogdan

    the bios should be a small square like chip. it's about one square cm and has something between 7-11 pins on each side. There isn't a generic layout for the location of this chip, it depends on the hardware configuration and the model number of your laptop. Each model has a different component layout so I can't point you to a specific area on the motherboard.

    If you find something similar to the brief description i gave you, just reply with it's code (imprinted on it's top) and i could then tell you if that's the chip.

Remove the battery and the power suppky from the computer. now, you also have to remove the backup battery which is inside the machine. It's probably underneath the keyboard. to remove this battery, go to support.lenovo.com and get the repair manual for your machine. It's really easy to do. after about 20 to 30 minutes, the password should be cleared out of memory.

IBM service dept. say that the mortherboard has to be replaced to make your laptop operational again.
Removing the BIOS battery will not work, the power on (boot up) password is stored on an EEPROM chip, Setting up (or removing/changing) the power on password and hard drive password is done via the BIOS configuration. There are no backdoor passwords available.
There is a way around this problem, it requires a bit of hacking.

Basically you need to build a piece of hardware to attach (solder it) to the EEPROM chip on your laptop, attach a connector from this piece of hardware to a COM port of working computer, turn on your laptop, then the working computer and run a reader program on the working computer to read the contents of the EEPROM chip, then located the password from the EEPROM data. Turn everything off, remove the piece of hardware from your laptop, boot it up our laptop and enter the password, now you should then be able to enter the BIOS to change/remove the password.

For details of how to remove the password check out :-

www.allservice.ro/forum

I have successfully removed passwords on both IBM and Compaq laptops, you need a steady hand and equipment.
If you are faint hearted about pulling apart your laptop, twist a friend's arm to do it for you.
Have fun.

There is a jumper on the motherboard that has 3 contacts, it may be labeled "CMOS". take the jumper from where it is and jump the post that it is not on and the middle post, leave it there for 2-3 mins. then put it back in it's original position, this will clear your CMOS and reset the password.

    Again to clarify.


    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.

Tip

How to Reset a BIOS Password.


Desktop Machines.

In desktop machines its very simple.
Just remove the BIOS Battery from the motherboard and place it back after 1mint.

Laptop Machines.

It is some what difficult in laptop machines. Because it is not an eassy job to remove BIOS battery from the mother board. So i'm just explaining some most commen methods.
1. Using a Backdoor BIOS Password

The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
Backdoor BIOS Passwords from Other Manufacturers Reported BIOS backdoor passwords for other manufacturers include:
Manufacturer BIOS Password VOBIS & IBM merlin Dell Dell Biostar Biostar Compaq Compaq Enox xo11nE Epox central Freetech Posterie IWill iwill Jetway spooml Packard Bell bell9 QDI QDI Siemens SKY_FOX SOYO SY_MB TMC BIGO Toshiba Toshiba Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

2. Resetting the BIOS Password using Software :

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

CmosPwd will recover the BIOS password for the following BIOS versions:
  • ACER/IBM BIOS
  • AMI BIOS
  • AMI WinBIOS 2.5
  • Award 4.5x/4.6x/6.0
  • Compaq (1992)
  • Compaq (New version)
  • IBM (PS/2, Activa, Thinkpad)
  • Packard Bell
  • Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
  • Phoenix 4 release 6 (User)
  • Gateway Solo - Phoenix 4.0 release 6
  • Toshiba
  • Zenith AMI
3. Resetting the BIOS Password using Hardware :

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

4. Vendor Specific Solutions for Resetting the BIOS Password :
Resetting a Dell BIOS Password For information on how to recover a Dell BIOS password, please refer to How do I reset Dell BIOS password?
Resetting a Toshiba BIOS Password KeyDisk will reset the BIOS password on Toshiba laptops.

Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.
Resetting an IBM ThinkPad BIOS Password For information on how to recover an IBM Thinkpad BIOS password, please refer to How do I reset an IBM ThinkPad BIOS password?
Resetting an IBM Aptiva BIOS Password Some IBM Aptiva's can be convinced to bypass the startup BIOS password if you press both mouse buttons repeatedly while booting the system.

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.

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

Reset password thinkpad 2656


Resetting the BIOS Password using Software Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.
You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.
!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:

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

Re: power on + bios password


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!!!!!!!!
