Laptop BIOS Master Password Generator

If you need your Laptop BIOS Password Reset, then you’ve come to the right place. Our 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.

Achieve Laptop BIOS Password Reset on late model HP, Compaq, Dell, Alienware, LG, Lenovo, Sony, Vaio, 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 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 @ 1024kb.co.nz.

Many HP/Compaq, Alienware, LG, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed, instantly & for free.

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.

NB: Use the hyphen key “-” as the date separator, not “/”.  Like this: dd-mm-yyyy, not dd/mm/yyyy. 

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.

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.

HP’s new i or I + 8-digit codes are correctly generated on this page.

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.

-8FC8 suffix is based on an entirely new method of creating the BIOS Master Password. We are working on the solution. 

-E7A8 suffix can be obtained in many cases, subject to individual calculation by Mikrover. PayPal donate & post your details.

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 Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.

Acer 10 decimal digits, 8 decimal digits
Asus Date code (Enter format as displayed on your laptop)
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, i + 8 digits
Insyde H20 8 decimal digits (Acer, HP)
Phoenix 5 decimal digits
Sony 7 digit serial number, 4 x 4 one-time
Samsung 12 & 18 hexadecimal digits

We are blessed with the voluntary assistance of Mikrovr in the comments section of this page. Mikrovr is the creator of many of the Laptop BIOS Master Password Generators used on this page, & has built other generators that he keeps private but generously contributes solutions from. I stress that his attendance is entirely voluntary & is something that I personally am very thankful for.

Because unpaid work is not a successful long-term model, I’ve added a Priority Service Donation button. If your BIOS doesn’t unlock using the free generator, click the PayPal button. Just $5 will make it happen for you. It’s a simple justification – Is that locked laptop worth more than $5 unlocked?  Yeah, I thought so.

*All donations go 100% to Mikrovr.

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 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….

This generator is based on the good work done by Dogbert, Asyncritus, hgpl & Mikrovr.


Guaranteed Priority Service

Mikrovr’s completely voluntary service in the Comments section here provides a valuable benefit by turning your locked junk into functioning laptops. You can easily value his input, it’s a lot more than nothing. He works too hard here for free, it’s just not a sustainable model. So we’re changing things to ensure he can continue delivering BIOS Master Passwords on request.

If you want your password request given priority attention, hit the PayPal donate button to the right. $5 will get your laptop unlocked along with instructions & follow-up attention if needed. Quote your PayPal transaction number to open your request.

No donation will attract an equal service – none. If the free generator does not solve your problem, $5 will.

All donations will receive Mikrovr’s attention, your password will follow shortly after.

Resellers & commercial users with multiple requests – one password per donation.

All funds received go direct to Mikrovr, the donations are 100% for his services.

  1. The administrative password is set on this computer. You cannot acsess Setup until correct password is entered. If you need to change any setup fields , you must first enter the administrative password in this field . Otherwise you can view the various settings and you may. Be able to change some depending on the way the administrator has configured the system.

  2. Thanks to you and the help of “Megabyte” the laptop is now fully functional after following your latest BIOS recovery instructions. The BIOS was unlocked on the first try! I reinstalled windows from a ISO on a flash drive as per suggestion from Megabyte. Thanks you sir for your assistance!
    Finally I would like to donate an additional amount via PayPal. Here is the Paypal transaction number 29M34824YS661344A.
    Once again thank you for a great service and my hope is you continue to serve the laptop and PC community!

  3. @David Johnson
    Thank you for acknowledging our work. What is the code, or message is displayed when asked to enter the password?

  4. First let me thank you for the rapid response!
    let me tell you what has transpired:
    1. I entered he “NEW INSTRUCTIONS” and lo and behold the DELL logo appeared saying “Please wait”. Now I was getting excited!
    2. Next came a “Recovery” screen telling me “A required device isn’t connected or can’t be accessed.”with an error code:0xc000000f.
    Choose one of the options below to address this problem.
    a. Press Esc for recovery
    b. Press Enter to try again
    c. Press F8 for Startup Settings
    d. Presse F9 to use a different operating system

    The only option that responded was a. Press Esc for recovery.
    After doing so the “Dell SupportAssist OS recovery started to load and has been loading for 30 minutes thus far.

    I guess I’ll wait ’til the morning to see if there are any results.
    Which leads me to a question, If I turn off the laptop will I still be able to use the code you provided? is there a way to bypass the Dell SupportAssist when the laptop first boots to the Dell logo?

    Well until the morning I bid you a good night and thanks again!

    1. The “required device” that’s missing is Microsoft speak for an active boot partition on your hard drive. An obfuscated description to say the least.

      Have you got a Winstall USB stick? Get one. Boot from it & do a complete fresh install – forget the Dell Recovery options. That’s my advice anyway, FWIW.

      Also, the first thing you do after entering your Mikrovr-made BIOS Master Password is clear the existing passwords. You don’t need those any more, move them on.

  5. @Walter Pietruk
    Disregard the password in the previous message!

    #1 – Enter calculated password, press and hold left CTRL key down, press ENTER key twice (CTRL-ENTER-ENTER).
    IMPORTANT: Give it at least 3 tries before continuing with traditional instructions, as some newer models require this alternate procedure.
    #2 – Enter calculated password and press ENTER key.

    Master Password from Dell A235D702 (via telephone call) didn’t work even after holding CTRL key and ENTER key first one time then CNTRL key ENTER key twice and of course ENTER without C NTRL key

    Here are some codes I have tried:

    Dell wants me to send in the laptop for $39 (round trip) then they will tell me what else I may need if I need further repairs.

    Help! I’m at my wits end!
    Thanks in advance for any and all endeavors on my behalf.

  8. @Justin
    Unfortunately there is still no solution using the master password for this suffix, we are working on this algorithm.

    Unfortunately there is still no solution using the master password for this suffix, we are working on this algorithm.

  10. That’s for sure. Most of these Latitudes all you need is a master password, or pull the time clock battery for cheap laptops. But so far these require a lot more to get there. I thank you for clarifying.

  11. I don’t believe you can… I have a 7400 that’s still locked. Apparently you have to find an unlocked bios to flash it with. I don’ really understand that myself and I am a fairly technical guy.

    1. It’s the border where software & hardware meet. An SPI reader/writer isn’t an expensive item, however the BIOS extraction, decryption & reflashing can be a taxing experience. There’s usually online help available for decrypting & cleaning BIOS/UEFI files but the physical dumping process is a hands-on gig.

      It’s not meant to be easy, it wouldn’t be called BIOS security otherwise.

  12. Hi,
    Lenovo T450
    TYPE 20BU-S02N00
    For Unlocking did you required anything else from my laptop for unlocking the bios password..
    Confirm me then I will donate.

    Master password is case sensitive

    Master password: vb0M5ISLbbD00M4Z

    v – victor ( lowercase )
    b – bravo ( lowercase )
    0 – ( digit )
    5 – ( digit )
    b – bravo ( lowercase )
    b – bravo ( lowercase )
    0 – ( digit )
    0 – ( digit )
    4 – ( digit )

    The Master password is hardcoded for US QWERTY keyboard layouts.
    Enter the Master password, hold down CTRL and press ENTER twice.

    After pressing ENTER twice while CTRL is held down this should clear
    out the bios password.

  17. Megabyte;

    Thank you for your response, I understand your statement’s position, too bad it gets taken over the edge so easily.

    You are right, I’ll start tinkering right away and while I’m at it I’ll create a brand new UEFI implementation.

  18. @Mikrovr

    We Madeline;
    Any news on progress on the 8FC8 suffix?

    I also got a trigger set for this Dell firmware code.
    Multiple people are hopefully waiting, can you give us an estimate or status update? It feels like you just pick stuff out of the que that can be fixed, but ignore the rest.

    Just a friendly, I hear y’all. Putting effort in it.

    (Hate to go the EEprom route, but now I have a paperweight on my desk)

    1. Anybody is welcome to develop the algorithm that will crack the Dell 8FC8 suffix, Mikrovr does not claim sole responsibility for this task.

      If your frustrations are getting the better of you & you simply cannot wait for Mikrovr or indeed someone else to release the required solution, there is nothing stopping you from building the keygen yourself. Also, you have the advantage of an -8FC8 laptop to test the solution on.

  19. I have emailed you more details about the locked SSD and the on-screen partial code – 2A7B (rest were hidden in ****) shown on my Dell laptop. In the past, you were able to unlock the password of original hdd on the a different laptop with limited info just like above. Are you saying the master password for Dell model will not work on the locked SSD? However, the hdd on the different laptop you helped unlock before was a SanDisk brand that’s not OEM drive either.

  20. @@Jing Lee
    Yes, it is possible to remove any 100% guaranteed HDD password as long as the HDD is on the same laptop.

  21. @Jing Lee
    even so, if you want I can calculate your master password. Although I’m sure it doesn’t work !!

  22. So do not you have a tool that removes any hdd password??

    I had an older western digital hard drive (not ssd) a few months ago that was the original hard drive in an Acer laptop. However, there’s no tool to remove the hdd password on the Acer laptop. I did have the password on that old hdd and put it into a different HP laptop that had security manager to remove password for the old hdd.

    If you can get me the correct master password on the WD 3D Nand SSD, then I can reset the password using Dell security manager. Will that work the same as the HP laptop security manager explained above?


  23. example:
    (laptop 1), blocked the HDD;
    (laptop 2), using the HD of laptop 1 even if you enter the master password will not be valid. You understand?

  24. I believe that you do not understand what I am explaining!
    It is only possible to unlock it with master password using the same laptop that locked it, if you don’t have the original laptop your HDD is doomed.

  25. This person has the same issue as me. https://www.dell.com/community/Inspiron/Locked-hard-drive/td-p/7331121 But my WD 3D Nand SSD is not the original hard drive for the dell laptop. The SSD is a retail SSD that can be used in any laptop for upgrade.

  26. I do not know if you remember the first time I donated and you helped me a few months ago. That was a different Dell laptop with bios password locked. You helped me clear the bios password first, but then there’s a hdd password lock. You asked me for on-screen code and cleared the hdd password later. This time I only have the issue with the western digital WD 3D Nand SSD being locked with a password, so I can put it into any laptop but need the password to be removed to use further. Thanks.

  27. Yes, it’s a standard WD 3D Nand SSD that’s not the original hard drive for any laptop. It’s used on another laptop for upgrade but that laptop has motherboard fried recently. The SSD is working and I used crystal diskinfo to check its health 100% with less than 2 TB read/write data and ran less than 300 hours so far. However, without the correct password, I cannot unlock the hdd or format it. I do not need any data in the SSD, since I will use it to upgrade another laptop and load fresh Windows 10 later.

    If you can unlock the password or provide a working master password, then I can donate again. Thanks.

  28. @Jing Lee
    Yes I can calculate the correct master password, more to work only if the HD was blocked on the same notebook by the user, if the HDD was blocked by another notebook, even typing the correct password will not work.

  29. I have the western digital ssd with me. When I plugged it into the Dell laptop, it asked for HDD password with a code displayed ****** -2A7B. I do not know the rest *** on the screen. Are you able to identify the master password on the Western Digital or WD Blue 3D Nand SSD to remove the old password, so I can wipe out the SSD on my Dell laptop? I am willing to do donation but I need a firm answer if the issue can be solved. Thanks.

  30. Hello, I got your service before and it’s great. I have a Western Digital SSD got locked with a password that I want to remove. I put it into a Dell laptop and the security manager on Dell asked me to enter a password. I do not recall the old password. How to remove the password? This password will carry over to any laptop not limited to Dell, so I need you to help me remove the hard drive password. Can you do that?
