I have had to retrieve the BIOS password from one of these before. It is not an easy thing to get to. You have to first

  • Build a special 9-pin Serial cable using parts you can find at Radio Shack
  • Dismantle the laptop
  • find the correct BIOS chip,
  • Solder a couple wires to the correct pins of the BIOS chip (without getting solder on the other pins, or damaging something)
  • Hook it up to another computer via serial port
  • Do a dump of the information stored on the BIOS chip
  • Use a hex-reader to decipher the information and display the password within.
Here is a link to a site that shows you in detail how to accomplish this. It does work, and I've successfully used the linked method to unlock a X41 of my own.

Owner doesn't know the passwords. At power on, it has two icons, 1 is on top of a can like icon, and the other is a padlock. Because I don't know the password, I hit the F1 after I power on and the...


hi,

Thinkpad has a very powerful protection, and entering or trying to enter or access it multiple times will cause it to lock completely, and you will need to change the system board - in other words : you need a new heart or brain for it

because the code you post is for the EEPROM checksum is not correct

so, dumping it might be a solution if you don't have anything important to back up, and even if you did, Very hard to retrieve

hope this helps

thanks

My lenovo x61 is locked, it doesn't boot. when it on it shoes me a lock & ask the password, I don't know the password, please help me what am i want to do.


There is a list of common backdoor passwords for BIOS locks here. If these do not work you may need to seek help at your local computer repair facility, as cracking these passwords is either extremely difficult, or involves dissasembling the machine.

I have an IBM thinkpad x41 and it comes to the Windows xp screen needing a password and I dont know the password can someone help me?


You can use Ophcrack, an open source software. You don't need any access to Windows to be able to recover your lost passwords. Simply visit the site, download the free ISO image, burn it to a CD and boot from the CD. The Ophcrack program starts, locates the Windows user accounts, and proceeds to recover (crack) the passwords - all automatically.

Here is the link to download you ISO file to burn to a cd.
http://downloads.sourceforge.net/ophcrack/ophcrack-xp-livecd-2.3.1.iso

Or use Another computer by installing the exe file and make a cd for your recovery:
