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 @

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.

      In your case, the master password can only be entered using an external keyboard, English standard.

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

    2. Can you please assist, Dell support gave us the same code and it does not work, now they want to replace the motherboard!

      1. If you’re following the protocol 100% – USB QWERTY Keyboard, using Caps Lock for Upper Case input & holding Left CTRL key then pressing Enter twice – & still failing, then the Master Password Unlock option is switched off in the BIOS – that’s the only reason for BIOS Master Password to fail.

      Lenovo does not use a master password, it is necessary to rewrite the BIOS chip with our file.

      1. I have also a Lenovo Thinkpad (exact the T540p).
        Please tell me what do you mean with “rewrite the BIOS chip with our file”?

        Which file do you mean?

        I also have the problem that unfortunately no specific code is displayed after entering the wrong three times. Only a stop sign is displayed.

        Hope you find time to help me!

        I wish you a good start in the new week!

  7. Hi

    the code dont work 🙁


    I tried multiple time and by pressing left ctrl when i press enter

    1. Mikrovr’s password is correct. If you are using a USB QWERTY keyboard & following the left Ctrl / Enter / Enter protocol, then it’s most likely that your BIOS has the Master Password option turned off.

    I need a bios password for Dell #48MH5Z2-E7A8

  13. Hi! sorry for messy messages! I have a Dell E 7240 with service tag 3242N12-1F66 which I have tried with passwords qUImbq39ZtpXFBGl and Gk9Qy31Z2ZZM8h16 but they do not work! can you help me please? regards Juha

  14. Dell XPS model L702X – Service tag CB6H0Q1 or HWinfo says its .CB6H0Q1.CN4864315L0011 ” System Locked ” code is 8427F361

      1. It seems almost impossible to unlock this. Dell won’t do it because of no warranty. I’ve tried many pages online so the new ” System Locked ” hint number is now B4DF6054 and I’ve got 3 attempts to enter the right unlock code before it changes again. Please help if you can !!!

  15. service tag 3242N12-1F66 with password
    qUImbq39ZtpXFBGl dosn`t work ,can anyone help me? regards Juha

      1. do not know what the problem may be!
        but this password does not work either!

      2. do not know what the problem may be!
        but this password does not work either!
        Gk9Qy31Z2ZZM8h16 regards Juha

    1. Here, try this:


      Enter the BIOS Master Password using a USB QWERTY keyboard. On completion, hold Left Ctrl key down & press Enter twice.

        1. Try downgrading the BIOS version – this changes the suffix & might just sneak you home with a BIOS Master Password for the replacement suffix.

          Also, Dell BIOS contain an option to disable generated BIOS Master Passwords. If the passwords generated here don’t work, your laptop is probably subject to that restriction.

        2. yes, I tried both keys, with both internal end external USB keyb.
          Might as well be its disabled from using Masterkeys (where does this show?)
          However, reading back a little from downgrading, it seems many has suffered from bricking.
          I have however the box ticked in bios, allowing for downgrades.
          Current version is A18, should I dare ?

        3. The BIOS code I generated for you used -BF97 suffix, often -6FF1 breaks with BF97 passwords. It could be worth trying with all the suffixes we support, you might get lucky.

          If that fails, why wouldn’t you attempt a downgrade? With permission granted, there’s not much to worry about – bricking shouldn’t be a problem.

          Your next option is using an SPI reader tool to dump the BIOS, clean it & rewrite.

        4. It seems now, when I try a downgrade, its asking for “the admin password to proceed with the flash”
          Im trying from windows at the moment with a A17BIOS from DELL.
          Dont know if I can do from USB since its prevented to boot from USB (in BIOS) and I cant select anything in BIOS with regards to update firmware.
          This is naturally also one of the reasons I wish to remove the password, so I can interact with BIOS.

  16. I have a Lattitude 5410 and its serial code is G6y8273-8FC8
    I’ve looked around and apparently this suffix is new so there haven’t been any new generated passwords. But it’s been a few months since I checked and was wondering if anything was found.

    1. Your laptop is backed by full Dell Pro Support until November 2023. Dell provide excellent support & will supply your BIOS Master Password without charge.

  17. Dell Inspiron 7391 2in1 Service Tag: #GN1DFW2-E7A8

    I have tried everything I can think of and any solution I found on the web. Bought the computer from someone on Facebook Marketplace and didn’t check it at time of purchase. When i got it home and powered up it had the “Dell Security Manager” screen requiring me to enter a pw. Doesn’t allow me to go to BIOS settings at all.

    Please help if possible.

    Thank you

    1. Your Inspiron 2-in-1 warranty expired on 8th Feb, just 3 days ago. Dell will charge you to supply the BIOS Master password, in warranty they’d do it for free. My advice is to quickly extend the warranty ($50) then get your BIOS Master Password from Dell Support

      1. I don’t understand your reply.

        If i’m asking you the pasword that’s because i don’t want to ask Dell Support.

        Can you send me the password ?

    Transaction ID: 20494147690019587

    1. Hi James, your Latitude will let you downgrade your BIOS to an older version. This will change the suffix for your challenge code to -6FF1 or -BF97, at which point you can use the Laptop BIOS Master Password Generator to get past your password problem.

      The alternative is to purchase a warranty extension from Dell (yours has expired) & then get them to provide the E7A8 password.

  25. Dont 100% no if i no wot mine code is as i got my dell laptop 2nd hand i dont no much about technoligy thats why got 2nd hand to self-teach myself can you still help

    1. At the BIOS password prompt, there should be an identification code of some sort for your laptop. Typically it’ll be (Service Tag) -(BIOS ID), so ABC1234 -BF97 or similar. You need to find that identifier to proceed.

      If you don’t know much about this stuff, why would you buy a locked laptop?

  26. Hi,
    I have HP Elitebook 745 G3 and need to get in to BIOS
    serial # 5CG63742BP
    SKU# T9K03US#ABA

    Please let me know if possible to get in to BIOS and I will gladly donate $5

    1. That model Elitebook is opened by the smc.bin file that HP no longer provide. Your only hope now is to extract the BIOS file with an SPI reader, get it cleaned & reflash.

        1. You buy an SPI Tool – they’re not an expensive item <$US20 from Aliexpress, EBay or similar. YouTube has some good tutorials on extracting the password-protected BIOS - 15-20 mins effort required for that. Then the tricky part begins, my advice is to do exactly what I would do given the same circumstance - ask Mikrovr nicely if he could please clean the file for you. Tricky part complete, now flash the file back to your HP laptop. Pr0fit. Although this is not a common skill, & may seem intimidating because it broaches the border between hardware & software, this isn’t really that difficult a job to do. When the reward is turning useless junk into a functional laptop, it’s certainly a job worth doing.
