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. Ericka – displaying her inability to read comments.
      I’m actually quite happy not doing business with you & knowing that your HP remains useless. So far today I’ve taken 10 HP UEFI solution orders & not once have I ever had to issue a refund. My solution works, your laptop doesn’t.

    I disassambled my notebook and under the RAMs two pins I connected 20-30 sec. G2201 BIOS password reset, G2101 and G2701 power button. It’s didn’t work too.

    Thank You

  9. I have a Dell Inspiron 15, the model number is 3521-6024, the service tag is CH36GW1. I have tried putting the service tag in the generator but nothing happens. Please help, I have been struggling for days with this.

    1. In the case of newer UEFI Dell laptops, your best bet is to contact Dell Support – they’re very helpful in situations like this.

  10. I am from india, i am having sony vpceh3aen laptop .which was locked bios from two years but it was working normally because i did not tried 3rd time and today i tried it my password is cracked with this site .i am very thankful to this website owner again thank you my english is poor

  11. The Button is not working for me. I have a Dell Servic tag DX64QY1 When I hit generate nothing happens.

    1. That’s because the Master Password Generator only supports Dell laptops with 7-digit code plus one of the following suffixes: -595B -D35B -2A7B -1D3B -1F66 & -6FF1

      If your system does not provide that type of System ID, all I can suggest is that you try official Dell Support, they are pretty good to deal with.

    1. Sorry, I haven’t got that algorithm, I don’t know anyone that does. You could always try Dell Support, they’re quite good to deal with.

  12. He’s referring to the “Crack” button on your webpage. It’s doing the same thing to me. Click and nothing happens. I’m going to try to update my Java and see if that helps.

  13. Thank you very much.Sony Vaio has reset the Notebook bios.
    I would also recommend your site to my friends.

  14. Hi there, I have an Acer Swift SF315-51 which produces a 10-digit numeric unlock key after 3 failed attempts. I’ve tried entering it with ctr+enter, I made sure to try using all forms of letters (l vs L, 0 vs o) but nothing works, it this because the algorithm only cracks 8 digit acer passwords?

  15. I thought I had a pointless contribution to the huge pile of electronic waste that we’re generating until my friend showed me this website. Now I’ve got an excellent laptop for university!

  16. Thank you so much, it really belp me bypass my laptop that i found in storage. Although i did get the right pw at another website they did not give me the hint of hitting control enter. Once again thankyou for your help.

  17. Hallo ich habe eine Toshiba Satellite c670d-126 bei dem kommt kein code was kann ich da machen bitte um hilfe

    1. Hey thanks Dakota, I didn’t realise that the Asus Master Password Generator wasn’t working. After some quick keyboard action, it is now. Check it out again. Your password is 0L2LBADB

    1. Dell tell me the process for entering the generated password in your laptop is:
      Enter the generated Master Password, press Enter. If the computer responds with the message Invalid Password, press the Enter key and continue to enter the same password three more times. After the fourth attempt the BIOS should accept the master password, clear the password and allow access.

        1. Are you entering the response code exactly as it’s displayed on the Dell? I don’t recall seeing a Dell response code with lower case characters. The Master Password for the one you gave – 230r3c2-1f66 – is w9C49rRZQWJFZlf6 (3rd last is lower L), whereas if we replace the lower case letters with capitals – 230R3C2-1F66 – then we get zYkqw19iDC5313B0.

          Does that help?

          1. Yes I used lowercase it just auto currected when I pasted it here I used one that started with z

            1. Pls I really need the hp mini code for ” i 60337746″ the accepted code is 16 letter unlike the generated one here that is 18 letters… thanks

            2. It’s that empty space causing an undefined input error. Where it’s expecting a defined character, there’s an empty space. Maybe take a second look @ your HP Mini?
