Seen this before? Bios-locked & password lost, that’s what that screen indicates.  But the System Disabled code displayed can often be decrypted to reveal the BIOS password. (The BIOS Master Password for this 2020 model HP Spectre x360 is 45670218 )

HP Spectre - BIOS pwnd

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, Alienware, LG, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed, instantly & for free. If it’s not available here for free, our sponsor will have your password available from just 5 Euro.

Hints & Tips

Individual brands have quirks specific to that manufacturer. Check your brand below - there may be secret sauce that enables your BIOS to crack.

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 the hyphen key "-" as the date separator, not "/". Like this: dd-mm-yyyy, not dd/mm/yyyy.

Dell use 3 minor inconveniences to defend their BIOS security. Without following their protocol, even correct BIOS Master Passwords will fail.

1. Use a USB QWERTY keyboad.
2. When entering an Uppercase character use Caps Lock, NOT Shift.
3. 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.

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.

-8FC8 & -E7A8 suffix are based on an entirely new method. BIOS Master Passwords are available after PayPal donation to support further research.

When asked for a password, enter -
First - 3hqgo3
Second - jqw534
Third - 0qww294e
The response is a System Disabled hash code. Enter that into the BIOS Master Password Generator to get your Fujitsu BIOS Master Password.

Many earlier Elitebook & Probook models on BIOS version lower than F60 are vulnerable to the Mazzif tool available from our downloads page. Full instructions included, be sure to read fully beforehand.

Newer HP BIOS Master Passwords with i, I or A prefixing 8 hexadecimal characters are successfully generated by the BIOS Master Password Generator.

If your Lenovo laptop has an Insyde H20 BIOS, then your secret sauce is to use a USB qwerty keyboard when entering the master password generated here. Forget your built-in laptop keyboard, use a USB qwerty keyboard.

Many Lenovo laptops do not use a Master Password system. These laptops require BIOS file rewrite.

Sony & Vaio brand 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 BIOS Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.

Sony 7-digit Master Passwords are successfully provided by the BIOS Master Password Generator

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.

Have you read the Hints & Tips for your manufacturer above? Now is a good time to do this.

Pay special attention when reading the code, be careful not to confuse lower L with upper i (l or I), zero & upper o (O or 0) - if your input is not exact, the response will not be correct & your laptop will not open.

Now enter that carefully-copied challenge code into the box below then 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....

Enter Your Code:

If the free Laptop BIOS Master Password Generator doesn’t unlock your laptop, you still have another opportunity.

The 5 most popular requests are all Dell laptops. If yours is -E7A8, -8FC8, no suffix Service Tag or System Disabled Service Ta then use the PayPal button below. Your password will be delivered here within a few hours.

  5. First off Transaction ID: 20493023422192526
    I have a Dell latitude 3310 and it has a BIOS PW.
    I greatly appreciate the help! Let me know if there is any other info you need from me in this instance! Thank you and Im hoping Mikrover will work their magic!!!

        1. Mikrovr has been ill with the virus. Brazil is not a good place to be right now. As we all know, it’s a nasty illness with lingering effects. Your $5 donation has helped him put food on the table this week, thank you for that.
          Please chill out, he’ll be back some time soon – exactly when I cannot tell you.

  6. I just used the BIOS Master Password Generator again myself. Successfully removed forgotten Administrator password from Dell Precision 7530 with -BF97 suffix. Used USB keyboard for entry, then held left Ctrl key & hit Enter. Ka-ching!!

  7. Hi, I see you guys are doing a great work here. I’m also looking for solution with Dell Latitude final -E7A8 and I can promise a good donation. Pls let me know how can I unlock this thing.


    1. @Vin
      Hi! We have the solution for your laptop, this suffix we found three variations, in some cases we have to modify the algorithm to generate the correct password. Surprise us with your donation, we will calculate your master password, just type it in to return completely unlocked.

      1. Hi Mikrovr,

        firs of all thank you for your reply and my apologies for my late answer.
        Unfortunately my boss took that laptop back, he kind of, don’t really believe guys like you can overturn that unpleasant situation.

        For sure I’ll be tuned in this channel from now on.

        Thanks a lot


  8. looking to get an admin bios password for my Dell
    I have made my donation
    Transaction ID# 2HX44201R9736892P

    1. @Michael

      Thank you for the donation, what code is displayed on the screen when asked to enter the password?

      1. hi Mikrovr, well I only got that screen once and cant seem to get back to it again all it seems to do now is want to change the password but it wants the original password first….ive tried to get that code to show again but cant seem to find it

        1. We can’t do much without that code Michael. Can you try removing the charger & the laptop battery, then press & hold On button for 30 seconds. Now replace battery, reconnect charger & reboot – try to get the challenge code now.

  9. Hi there, I’m happy to donate if an unlock key exists for my machine.

    Dell Latitude 5410
    system number: 4PQBN53-8FC8

    1. There is no successful algorithm for -8FC8 yet. You don’t actually need one anyway Nish, your laptop is covered by Dell extended warranty until July 2023 – contact Dell Support, they deliver awesome assistance & will solve your problem quick smart.

  10. Hey Mikrovr!
    Can you please help me with an Dell 5JLGZF2-6FF1? I‘ve even tried with -BF97 suffix but it apparently won‘t accept the generated passwords.

    1. Bruh, just follow the protocol please. Open your request with your PayPal transaction ID – $5 isn’t much compared to the value boost from an unlocked laptop.

    2. @Rup3

      Master password is case sensitive
      Master password: rWRcztQIRSb4zK3n

      r – romeo ( lowercase )
      c – charlie ( lowercase )
      z – zulu ( lowercase )
      t – tango ( lowercase )
      b – bravo ( lowercase )
      4 – ( digit )
      z – zulu ( lowercase )
      K – KILO ( UPPERCASE )
      3 – ( digit )
      n – november ( lowercase )

      The password can contain numbers, special characters, upper and lower case
      letters, hardcoded for US QWERTY keyboard layouts.

      After entering your password DO NOT press ENTER, hold down the left CTRL key
      and press ENTER twice.

  11. Hello,

    I have a Fujitsu Lifebook U758
    System disabled: 203c-d001-d56e-0d13-3583-5db0

    None of the known generators will work with 6×4 hex

    Transaction: 20489541457781422

    Thanks in advance

    1. Have you tried the Python script for FSI 6×4 on the Downloads page? Give that a go, let me know the result.

      NB: You will need Python 2.6 specifically, the script won’t run on any other version.

      1. Yes, I tried the script(s) before I posted here on this site. Python is 2.6.
        Result: Script just quits. No result, no error message, window closed.

        1. The script does work, I’ve just tested to make sure.
          Try this – assuming you’re on Windows 10, download & install the Python-2.6.amd64.msi executable to your System Drive (C:}. You now have Python installed at C:\Python26.
          Save the python script download from this site by right click, Save File as.
          Now go to your download location & double tap the script.
          A CMD window will load Python 2.6 & run the script.

        2. I’m sorry, but for me it doesn’t work.
          Python is 2.6.2 (64 Bit). Script is “” from your download section.

          When I put in a random DECIMAL Value like “1234-4321-1234-4321-1234-4321” I’ll get a result, ok.

          But, when I put in my system disabled HEXADECIMAL Value: “203c-d001-d56e-0d13-3583-5db0” the script crashes.

          No idea what I do wrong, but when it works at your place, I would by satisfied when you just post here the result for 203c-d001-d56e-0d13-3583-5db0

          Thank you very much

    2. @Sven
      I need to check this algorithm, Fujitsu-Siemens it’s a mess, in the way that there are just too many algorithms, some decimal and other hexadecimal, 6×4 and other variations…

    Let me know if there is any other info needed

    1. There is still no solution for this suffix, your laptop is still under warranty until 22 JUL 2023, contact the manufacturer, they can help you.

    1. @Saleh
      There is still no solution for this suffix, your laptop is still under warranty until 11 DEC 2023, contact the manufacturer, they can help you.

  15. HI,

    I Have come across a E7A8 Suffix that I have not seen before and cant be unlocked here. All others I have tried have worked. Anyway I am not sure I understand how the donation works, I can do the Donation which I dont mind doing AT ALL! I just dont know how to get the unlock code after I donate??? If you could give me instructions I would appreciate it. Thank You

    1. @Tracy
      This suffix uses three variations of algorithm, for some models it is not yet functional. What is the service tag number?

    2. @Tracy
      The donation is just to maintain our project, do it out of your will or gratitude, we do not sell our service.

    3. All you do Tracy, is open your BIOS Master Password request with the PayPal transaction ID. Mikrovr posts his response shortly after. As he said, it’s not a purchase you’re making – think of it as a pay it forward transaction that enables him to be here next time you need a BIOS Master Password generated.

    1. @andy
      When asked to enter the password, enter “12345678” three times, check if the “System Disabled” code has been changed?

      After entering the wrong password for the third time, you will receive
      hash code out of eight digits from which the password can be calculated.
      e.g. [I 12345678], [i 12345678] or [12345678]

      Enter hash code: i 86075602

  16. Hey all, the sudden flurry of activity here is because of one man – Mikrovr – returning to provide unlock codes for your laptops. He’s been missing for a few weeks due to having caught Coronavirus & suffering through that illness.

    If you haven’t donated yet, please do so now. It’s Mikrovr’s efforts that make this website as useful as it is. Please help ensure that he has a reason to keep coming back.

    Cheers, thank you.

  17. Hi, I will try to keep it short but I have already tried everything to get rid of an admin password on my old Alienware 14 (2013). Incl. desoldering the BIOS IC, dumping it and poking around the dump in UEFITool. I also replaced the BIOS and EC bins with ones from a different machine but the password remained, so I am guessing that the password is stored in KBC. Also, I got a master password generated by dell support. None of the generated ones worked. So I am either dumb and am not entering the pwd correctly or I haven’t found the correct key yet. You are my last resort. Can you please help me with this one? (Please let me know if donation is required for this one)

  22. Hello,

    I have an HP Envy x360 m Convertible that is currently locked due to a BIOS password. The model number is hp envy 15-bp108ca and the halt code is A [BFECB8FO]. I am not sure if the last is an O or 0. It looks like it’s an Insyde BIOS. Can you please help?

        1. That’s not a known pattern on any BIOS that I’m aware of. However, if you replace the letter O with numeral 0, it fits the HP AMI algorithm.

          Password is 8f7997f4

      1. I tried the code and unfortunately it did not work. Can we try again? Here the code typed exactly as it appears on my laptop.

        A [5650FA07]

  23. CMJCFP2-E7A8

    Dell G3 3779

    Nothing seems to work . It’s for bios and does it matter if I do not have the original hard drive but an upgraded one?

    1. Mikrovr is currently working on the E7A8 algorithm. This & the -8FC8 are a lot more complicated than the previous solutions. We’ll be publishing the news as soon as his work is complete.

      No, it does not matter which HDD you have installed for a BIOS PW. The BIOS PW is stored in a chip on the system board, not on the hard drive.

      Thanks for visiting, sorry we can’t help you out just yet. Hopefully it won’t be long til we can.

  24. Lenovo thinkpad x1 carbon
    It opens when you press enter but the settings are not active
    Didnt show the system disabled code

    1. Not all Lenovo are vulnerable to BIOS Master Password generation. For Thinkpad Carbon X1 you need an SPI reader to grab a dump of your password protected BIOS, get it cleaned & re-write it.

      If it’s just Windows access you need, remove the X1 SSD & install it in another PC. Now do your Winstall. When complete, return it to your X1. Now your Carbon is fully functional apart from BIOS access.
