If you need your Laptop BIOS Password Reset, then you’ve come to the right place. The Laptop BIOS Master Password Generator reveals the password for many popular laptops. Not all laptops are vulnerable but many are – give it a try, it’s free.

Latest Update 11/19 – New & improved now cracking even more late model laptops!

Added Dell XPS, Latitude & Precision machines with -BF97 BIOS suffix, improved -6FF1 password generation plus most FSi models. – see details here

Achieve Laptop BIOS Password Reset on late model HP, Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo & Fujitsu & more brand name laptops with the Laptop BIOS Master Password Generator!

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.

    1. The algorithm works, it can only be input. If you’ve already held the left Ctrl key while entering (& pressed Enter twice) then try it with the right Ctrl key. Failing that, grab hold of a USB keyboard & try again with that.
      I’m going to email you on a separate subject, you may be able to help me.

    1. Some Dell service tags are missing a suffix – just try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66 or -6FF1 to your service tag.

  10. It worked for me but i forgot to disable the administrator password. I restarted my laptop and now the administrator lock is back. How the hell could this happen?

  12. Hi Megabyte, tried to do a dell(1QVLM32-1F66), but your gen is not working, nothing comes as result. It worked for me in the past a couple times, thanks for your awesome solution anyway but did you update your code again? 🙂 (tried edge and FF)

    1. Hey thanks for the heads-up. I’m still not sure exactly what caused that, my suspicion is the Cloudflare caching rules that I created yesterday. Anyways, it’s fixed & doing what it does – generating BIOS Master Passwords.
