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 )

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
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.
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 Mikrovr. PayPal donate & post your details (incl PayPal Transaction ID) for priority attention.
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.

Please tell me what do you mean with “rewrite the BIOS chip with our file”?
Which file do you mean?

Hope you find time to help me!

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.

Thank you for the great effort!
However, this is not working too…
are there more than 2 set of keys available?
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.
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 ?
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.
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.

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

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.

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
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?

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 $5
That model Elitebook is opened by the smc.bin file that HP no longer provide. Your only hope now is to extract the BIOS file with an SPI reader, get it cleaned & reflash.
Thank you very much for your answer. How do I do that ?
You buy an SPI Tool – they’re not an expensive item <$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.
