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 @

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 keyboard to enter the master password generated here, then use a USB QWERTY keyboard to enter password.


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.

Fujitsu Siemens

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.

Real Person Help

We are blessed with the voluntary assistance of Mikrovr in the comments section of this page. Mikrovr wrote some of the Laptop BIOS Master Password Generators used on this page, & has built many more 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.

Should the generators onsite here not provide the solution for your laptop, then join the conversation below. Ask the man himself, Mikrovr, to help you out. Make sure you leave full details – brand, model, response code to get the best possible chance of a solution.

Mikrovr’s solutions are the real thing. If he chooses to assist you to unlock your laptop, then you can say goodbye to the BIOS password. What else you can say is Thank You to him, seeing as he’s just turned useless junk into a laptop for you.

Mikrovr supports Child Cancer Charities in Brazil, it’s hard to find a better cause. Those who are able could truly display their generosity by sending a PayPal Donation to [email protected]

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…
