      Hi Joel,

      You need to type in the BIOS code exactly as shown. Capitals and all.
      If you type correctly, the unlocking password will be displayed on the computer screen and you can type that into the laptop to unlock it.

      Dear Joel,

      The program was written in the Python language and you need to install Python Runtime for Windows to run it.
      Hopefully you will be able to figure out how to install Python and run the program. If not, use the ‘Contact Form’ (not in comments) and let me know the:
      – Make, Model, Serial of your laptop
      – The BIOS code that is being display (type capitals as capitals, lowercase as lowercase. spaces, dashes matter – so type it accurately.)

      Dear Karim,

      The password of the Dell 6400 is stored in NVRAM. You cannot remove it by removing the battery alone, it needs a motherboard soldering job.
      Alternatively, you can try the utility that is mentioned in the blog article. Its a free software and if you give it the BIOS code, it will tell you the backdoor password to remove the existing password.
