Laptop BIOS Master Password Generator

When you open a laptop & find yourself faced with the immediate black BIOS password screen & absolutely no idea of what password you used, all you gotta do is come to the Laptop BIOS Master Password Generator @

Many HP/Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed.

Hints & Tips


In the case of Asus laptops it’s the date code you require – enter an incorrect password then press Alt +R at the next prompt. Take that date & enter it in the BIOS Master Password Generator below in the same order (yyyy-dd-mm, mm-dd-yyyy or dd-mm-yyyy) as displayed on your Asus laptop.

NB: Use – as the date separator, not /.  This way dd-mm-yyyy, not dd/mm/yyyy. 


If your Lenovo laptop has an Insyde H20 BIOS, then your secret sauce is to use a USB keyboard to enter the master password generated here, then use a USB QWERTY keyboard to enter password.


For HP’s popular Elitebook & ProBook, there is an alternative method available here in the downloads section. Highly effective on vulnerable machines, full instructions included – please read them before you attempt BIOS password removal.


Press & hold the left Ctrl key when entering the password in Dell laptops, then hit Enter twice. Some Dell service tags are missing a suffix – first try the password generated, then try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66, -6FF1 or -BF97 to your service tag.

Many -6FF1 machines are cracking with our new -BF97 codes. Simply exchange the suffix on data entry then generate your code. (Don’t forget, left Ctrl then Enter + Enter)

Downgrading the BIOS can change your suffix, resulting in a successful password generation. If your BIOS is set to allow downgrades, this method will help.


For the later 6×4 password implementation, download & install Python 2.7 (available for all platforms), then grab the Fujitsu 6×4 Python script & save it in your Python directory. Double-click on the script, follow the simple instructions,  all done.
(Edit: I’ve now added the 6×4 script to the BIOS Master Password Generator)


Sony 4 x 4 Challenge Codes are a one-time password, generated fresh each boot. Do not turn the laptop off after obtaining the Challenge Code as the Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.

We are blessed with the voluntary assistance of Mikrovr in the comments section of this page. Mikrovr is the creator of many of the Laptop BIOS Master Password Generators used on this page, & has built other generators that he keeps private but generously contributes solutions from. I stress that his attendance is entirely voluntary & is something that I personally am very thankful for.

Should the generators onsite here not provide the solution for your laptop, then join the conversation below. Ask the man himself, Mikrovr, to help you out. Make sure you leave full details – brand, model, response code to get the best possible chance of a solution.

Mikrovr’s solutions are the real thing. If he chooses to assist you to unlock your laptop, then you can say goodbye to the BIOS password. What else you can say is Thank You to him, seeing as he’s just turned useless junk into a laptop for you.

Anyway, whichever BIOS-locked laptop you have, grab the Machine ID Code – sometimes called the Service Tag, Challenge Code or Response Code  – usually displayed after submitting a few (3-5) incorrect codes – that’s the unique identifier we need. Pay special attention when reading the code, be careful not to confuse I & l or O & 0, B & 8, S & 5.

Now enter that code in the box below, hit the Crack It button…. Ka-ching!! No surveys to fill out, no pop-under pR0n adverts, just pure goodness & quite likely your Laptop BIOS Master Password too.

When you’ve done your Laptop BIOS Master Password Reset, please leave a comment, send a tweet, or do whatever peeps do on Facebook to tell the wwworld about your win…

        please help

  13. i have 18 hexdasimal code in samsung bios password any one brack it ??? +923030962009 Contact with me

      1. To everyone that is having trouble with Dell passwords you must remove the hyphen before the last four numbers . And after entering the code hold the left control button and hit enter twice. I’ve gotten passports for about 20 different Dell laptops on the site and every password worked.I hope this helps

        1. This.
          Thank you for the advice given above Walter.
          I didn’t know about removing the hyphen preceding the suffix giving different results. The decrypting script should strip the hyphen out.

  14. I have an HP Pavilion HP 15-au018wm that generates the bios lockout code- I 60149057. Anyone know the code to bypass the bios lock on this model of HP laptop?

    1. Late model HP are a problem ATM, since HP stopped providing the smc.bin files that are used to clear BIOS passwords. There is a way around though – does your ZBook boot into Windows? If so, install the HP BIOS Configuration Utility –
      v4.0.15.1. That version has the ability to change/remove BIOS passwords from Windows, later versions had that superpower removed.

      1. thank you sir, you are so kind. I can login to my Zbook 15 G4 Win10, But it seems the HP Bios Utility needs the old .bin/passwd

        1. I bought this refurbished machine from ebay. I don’t have the old .bin/passwd
