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

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)

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

Asus

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.

Dell

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 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

Sony 4 x 4 Challenge Codes are a one-time password, generated fresh each boot. Don't 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.

Partial List of Vulnerable BIOS

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

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 ,

“, in which he promised to write about how to set a password in BIOS. So I’m keeping my promise, now I’ll write and show you how to install, remove, or reset the password in the BIOS.

But first, let's figure out how effective a password is in the BIOS system and how it helps protect your computer. Personally, I think that the password set in the BIOS does a better job of protecting your computer. It’s just that the password set in the operating system can be hacked programmatically, but the password in the BIOS, as far as I know, cannot.

After pressing “Enter”, a window will appear in which you need to enter a password. I can enter a password of 6 characters. We invent and remember good password, enter it and press “Enter”.

Another similar window will appear in which you need to enter a password confirmation. Enter the password again and press “Enter”.

That's it, the password is set, but after this setup, the password appeared only when I tried to enter the BIOS, and the computer turned on as usual without a password. In order for the password to appear when you start the computer, you need to make one more setting.

Therefore, we immediately select the tab and confirm the choice by pressing “Enter”.

Next we look for the item “Password Check”. Opposite it, I had the “Setup” parameter set, which meant asking for a password only when entering the BIOS. You need to change it to the value “Always”. We do this, press “Enter” and select “Always”. Now the password will be requested both when entering the BIOS and when starting the computer.


Now the most important thing is, don't forget to save your changes. Press the F10 key and “Enter”. The computer will reboot, and as soon as it starts up, a window will appear asking for a password. Enter our password and press “Enter” (sorry for the photo quality).


That's all, the BIOS password has been set, and your computer is now protected. Let's move on.

How to remove password in BIOS?

We have set a password, now we will shoot :). This is not yet hacking (resetting) a password, it is deleting it. Perhaps you didn’t like it, or you no longer need it.

We do everything the same way, go to the BIOS, select “BIOS Setting Password”. A window will appear asking you to enter a new password, do not enter anything, but immediately press “Enter”.


A window will appear with the inscription “Password uninstalled” (password removed), press “Enter” again. Save the result by pressing F10 and “Enter” again. That's it, the password has been deleted.

How to reset BIOS password?

First we set the password, then we deleted it, and now I’ll tell you how you can reset the password in the BIOS, that is, hack it. But this is not advice on hacking other people's computers, this is so that you can reset the password if you suddenly forget it.

As I already wrote at the beginning of the article, reset your password to regular computer Easier than on a laptop. Just to reset the password that is set in BIOS system, we need to reset the BIOS itself. Read more about how to do this in the article. There you need to either close special contacts or remove the battery for a while. After which, the BIOS parameters will be reset, and the password will disappear with them. It's the same in laptops, it's just more difficult to disassemble.

Well, it seems like I wrote everything, try it, just be careful and don’t press anything unnecessary, otherwise you’ll get into trouble. Good luck!

The most common method that most of us know to reset or clear the BIOS password is to physically power off the computer by unplugging all cables and removing the battery from motherboard for a few minutes.

Another way how to remove bios password— switch the CMOS jumper on the motherboard itself, if present. These methods work because most PC motherboards and a number of laptop motherboards use a battery to maintain BIOS/CMOS settings. If you turn off the power, BIOS settings/CMOS and password will be deleted.

If for some reason you can't reset your computer's BIOS security password by removing the battery or toggling the CMOS jumper, here are a few options to try.

Default backdoor passwords

Before using tools that try to reset or make changes to the BIOS, it's worth seeing if any of the known backdoors or default passwords are working. Click the link below to view a list of all known backdoor passwords. Before you remove the BIOS password on your laptop, please note that passwords are case sensitive.

Standard BIOS backdoor passwords

If you can boot Windows

CMOS De-Animator is more modern instrument compared to most tools. It can reset BIOS password from Windows. Latest version CMOS De-Animator 2 is compatible with both 32-bit and 64-bit operating systems.

All you need to do is run the tool as administrator ( right click and select menu item " Run as administrator» ) and press the button " Continue", and then restart the computer. When the PC boots, you will see a CMOS checksum error and will be able to access the BIOS without a password. The way CMOS De-Animator works is that it invalidates the checksum CMOS memory system. This resets all settings to default and clears all stored BIOS passwords.

CMOS De-Animator includes backup and restore functionality. This provides an additional guarantee of safety. If something goes wrong when resetting passwords, the data is saved to a file with a .dea extension. The authors of the program warn about possible problems when using it on laptops. The program sometimes causes antivirus software to cause false positives and warnings on sites such as Virus Total.

If you can't boot from your hard drive or CD

How to remove bios password on Samsung laptop? Turning off the power and removing the battery from the motherboard desktop computers This should remove the BIOS password for a few minutes. But this is much less likely to work on a laptop. For added security, laptop BIOS passwords are typically stored on a separate EEPROM chip that is independent of the BIOS battery.

If you enter the wrong BIOS password on your laptop several times, a message will appear on the screen indicating that the laptop is locked. You will see something like “ System Disabled" or " Password check failed. System Halted” and a few numbers. If this message appears when entering the BIOS, you can simply turn off the power and then try to enter again. Pay attention to the number because it is valuable information. It is required to generate a backdoor BIOS password.

All you need to do is write down the number that appears and then go to the web page BIOS Master Password Generator. This site is designed to retrieve possible passwords based on the entered number. Just enter it and click the button. Then check the results and mark all the passwords that are close to your laptop model.

Before you remove the BIOS password on your computer, try the received codes for a locked BIOS to check if it works. Depending on your laptop model, you may need to press Enter or Ctrl + Enter after entering the code. The codes used are based on the work of a specialist " Dogbert", who did a lot of research and created a number of small utilities, as well as Python scripts for unlocking various models laptops.

If the codes you received on this site did not help you, visit Dogbert's blog, where you can find more detailed information about the brand of your laptop and download a separate utility for it. To use one of the programs, download the utility and run it, then enter the number and press Enter. You will receive a master password with which you can try to unlock your computer.

You need to run the master password on a computer that can boot to Windows and that has .NET installed. If you don't know which tool to use, you can try everything until you find the one that suits your laptop.

If you can boot from CD/USB

When Windows does not boot properly and there is no way to log in or USB is already set to a higher priority. In this case, you need to insert a CD or flash drive and the device will boot from it automatically. Also, booting from a CD or USB drive may have a lower priority than hard drives. In this case, you will need to temporarily disconnect the hard drive.

How else can I remove the password through the BIOS? If you have access to Windows, another solution that allows you to boot from CD/USB is a tool called Plop Boot Manager. It makes it possible to boot from these media even if the BIOS does not support this feature.

Here are some tools you can use when booting from a CD or USB flash drive.

PC CMOS Cleaner

Designed to recover, delete, decrypt and display the user or super user password stored in the BIOS, regardless of the device brand. Supported BIOS include Award, American Megatrends (AMI), Compaq, Phoenix, Samsung, IBM, Compaq, DTK, Thinkpad, Sony, Toshiba. So there's a good chance that your BIOS is included in this list. PC CMOS Cleaner is a bootable Linux CD, so you don't have to worry about operating system compatibility.

When launched, the program will first try to decrypt and display the list possible passwords. If that fails, you can remove the password using two options, the second of which will completely reset the BIOS settings to default - you'll have to reconfigure them later.

!Bios from Eleventh Alliance

Allows you to back up and BIOS recovery. There's even a Blaster option that can wipe certain parts of the BIOS with the expectation of removing the password - a powerful and potentially unsafe option as it can corrupt the BIOS. !Bios can crack passwords used in some common BIOS versions, including different versions IBM, American Megatrends (AMI), Award, and Phoenix. This is an old tool, dating back to the late 90s, so it is unlikely to work effectively on modern computers.

Hello everyone, today I’ll tell you how I reset the bios password if such a need arises. I’ll tell you both physical and software methods, they all have their advantages. Who could find themselves in such a situation, in theory, anyone, since in lately vendors producing equipment are increasingly taking advantage of this opportunity, so that by new technology, to you when purchasing a used one. computer or laptop, you may also be lucky enough to get acquainted with this situation, maybe you will even buy a bios code decoder program.

There are times when people try to achieve maximum security or, on the contrary, do a dirty trick by setting a password to enter the BIOS. Let me remind you that BIOS is a microprogram that helps your hardware interact with each other, if only superficially. Having access to the BIOS, you essentially get access to the brains of your laptop or computer; it is there that hardware settings are made or boot priorities are set for installing the system from a flash drive or booting from a PXE server. Naturally, if this is an organization’s computer, then the security service may require that the system administrator set a password there, for those who are especially inquisitive, or the situation may be that hardware manufacturers may block access there, and you need to reflash the bios, situations can be different. The main thing is that the task is to produce and you, as an engineer, must be able to do this.

BIOS reset methods

There are two ways to reset the CMOS memory. Let me remind you that CMOS memory (Complimentary Matal-Oxide-Semiconductor) is needed by the BIOS to store data in it, which requires constant recharge from a battery installed on the motherboard:

  • this is a physical effect on iron
  • using utilities

And so, when you try to enter the BIOS, you see these pictures

Software reset bios password

We launch debug.exe and enter our codes for each BIOS version.

  • q – quit
  • the first number in each line is the port
  • the second is the number of bytes (in hexadecimal)
  • In the command prompt window, enter exit (or just close the window);

Physical password reset

How to reset a bios password if you were unable to reset the password using the above utilities, then try the following methods

  • Remove the battery from the motherboard and wait a couple of minutes. Once pulled out, be sure to remove the power cord from your system unit or the battery on a laptop, then press the power button, the fans will spin a little and the residual energy will go away.

On laptops you can also try to close the contacts where the battery is, just be sure to remove the battery before doing this

  • On most motherboards you can find a reset button CMOS It is most often located next to the battery. To clear memory CMOS you need to close these connectors, then turn on the PC and reset the BIOS settings.

or something like this CMOS.

how to reset bios password with master codes

I already described the principle in the article How to reset the BIOS password on ASUS. This method is suitable for aser or e-machine laptops, and others. What we do is turn on your laptop and try to enter the BIOS. We see the password being entered.

We enter the wrong password several times, any password will be wrong, the chance of guessing is negligible.

A menu appears in which you select Enter Unlock Password.

Here you are required to enter a certain master code, below I will teach you how to receive it. We write down the code 54697781, it will help us crack the bios password

Now we need to use decryptors, I will show you two online.

http://service.wna.ru/rus/useful/udalenie_parolya_na_noutbuke.html

Below in the field Enter the code here we paste the copy copied above 54697781, you will have your own code.

We see everything, we have received two master passwords, the lower one will suit us, and we can now hack the bios password

Today we will look at:

In the previous article we raised the issue of different versions and described this process for several BIOS versions. Today we will continue this topic and take a look at a situation where a previously established protective combination was lost or forgotten.

In this topic we will talk about the so-called BIOS Master Password services and tell you what it is and how to use it.

BIOS Master Password: what is it?

The BIOS master password generator is a special service that allows you to remove the BIOS lock. Similar blocking occurs when the user enters three incorrect password in a row, after which the system displays the message “System Disable”.

How to use the BIOS Password Wizard?

Similar services for selecting master passwords have the same operating principle. The first thing you need to remember or write down somewhere is the code that is displayed when the “System Disable” message appears.

The service will select a service password for your laptop or motherboard model, which will always be suitable for this device.

There are a lot of services, both English and Russian, for selecting BIOS passwords. They are all “single-button”, so we see no point in disassembling them separately. To get acquainted, we recommend taking a look at the service bios-pw.org, which will clearly show how to work with such BIOS master password generators.
