Laptop BIOS Master Password Generator

If you need your Laptop BIOS Password Reset, then you’ve come to the right place. The 1024kb.co.nz 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.

Latest Update 11/19 – New & improved now cracking even more late model laptops!

Added Dell XPS, Latitude & Precision machines with -BF97 BIOS suffix, improved -6FF1 password generation plus most FSi models. – see details here

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

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.

NB: Use – as the date separator, not /.  This way 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.

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.

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.

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 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.

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. Lenovo BIOS has so many twists & turns. That padlock symbol indicates which level of lock you’ve got. Your best solution is to dump the bios with an SPI reader, decrypt, remove the password & re-flash. You’ll get quality guidance from the peeps @ ghostlyhaks.com & mydigitallife.com

  17. Owwww yeah !!!

    I have a very old Dell Latitude X1 that got stuck with the dreaded system password needed message.

    I entered the serial number in the code field and it gave me a couple of passwords.

    The second one was the good one !!!

    I entered the BIOS and disabled the system password so it would not bother me anymore.

    Thank you ! Thank you !

  18. Não consegui resolver o problema do meu setup, a senha que aparece depois de eu ter inserido os 18 digitos, vem systema não aberto…

Requesting an unlock code? Have you donated?
