Those manufacturers listed above – your BIOS is brake. All your password are belong to us. (Well, nearly all.)

8-digit BIOS provided by Insyde H20 (Lenovo, HP) and 5-digit Phoenix BIOS are also pwnd by the Laptop BIOS Master Password Generator.

Seen this before? Bios-locked & password lost, that’s what that screen indicates.  But the 20-digit machine ID code displayed can often be decrypted to reveal the BIOS password. (That code reveals a Fujitsu-Siemens laptop with password 9538393)

And what?

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.


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.

Fujitsu Siemens

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.

Partial List of Vulnerable BIOS

Compaq 5 decimal digits, 10 characters
Dell BIOS code ending with -595B, -D35B, -2A7B, -1D3B, -1F66,-6FF1 & now -BF97, also generates master password for Dell BIOS with no suffix.
Fujitsu-Siemens 5 decimal digits, 8 hexadecimal digits, 5×4 hexadecimal digits, 5×4  & 6×4 decimal digits
Hewlett-Packard 5 decimal digits, 10 characters
Insyde H20 8 decimal digits (Acer, HP)
Phoenix 5 decimal digits
Sony 7 digit serial number, 4 x 4 one-time
Samsung 12 hexadecimal digits
Asus Date code (Enter format as displayed on your laptop)

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.

    Can you help me?

    1. Lenovo BIOS has so many twists & turns. That padlock symbol indicates which level of lock you’ve got. Your best solution is to dump the bios with an SPI reader, decrypt, remove the password & re-flash. You’ll get quality guidance from the peeps @ &

  7. Owwww yeah !!!

    I have a very old Dell Latitude X1 that got stuck with the dreaded system password needed message.

    I entered the serial number in the code field and it gave me a couple of passwords.

    The second one was the good one !!!

    I entered the BIOS and disabled the system password so it would not bother me anymore.

    Thank you ! Thank you !

  8. Não consegui resolver o problema do meu setup, a senha que aparece depois de eu ter inserido os 18 digitos, vem systema não aberto…

    1. Josh, hard drive passwords are specific to the laptop that they were originally locked with. Without that laptop, I’m not aware of any recovery available.

  9. I have the dell latitude 7490 and its stuck on dell security manager page when i turn it on. None of the codes work and there us very important stuff on my laptop please help

    1. Hi Katie, did you hold the Ctrl key & press Enter twice? That’s caught many people out. If that didn’t work, try flashing a different BIOS firmware, download from Dell Support. That’ll give you a new System ID code that we can generate the master password for.

  10. Hi
    I used this free password generator. It’s gives master passwords but password is not working.
    My Dell latitude E5500 code is 1R8LD4J-1F5A

    1. Miles, straight up, click the link, it’s $40 for a guaranteed solution. Your HP 15 will be password-free or your money back. (We’ve never had to refund yet.)

    1. The solution for 1F5A bios to override master password on Precision M4500 is to downgrade the BIOS using this method:
      Download M4500P02.exe BIOS update from Dell Support, then use this CMD to create .HDR file “M4500P02.exe /writehdrfile”.
      Now copy M4500P02.hdr to a USB flash drive. Shut down, remove battery and power from your Precision M4500, connect the flash drive.
      Hold END key while you plug in power cord and release END when the battery LED light comes on.
      If the LED light blinks red/blue it’ll be flashing successfully – wait till the laptop restarts.
      Now you have downgraded your BIOS and the 1F5A should be changed to 2A7B / 1F66 – the online generator will work.
      (When you type the master password, hold RIGHT CTRL, then ENTER twice.)
      I used M4500P02.exe as an example because it’s the earliest BIOS file for M4500, there are other BIOS updates available. All you’re looking for is to change your 1F5A suffix.

  14. Supervisor…no option to change something in bios..but boot option is can be installed,
