", in which he promised to write about how to set bios password. So I keep my promise, now I will write and show how to install, remove, or reset the password in the BIOS.
But first, let's see how effective the BIOS password is and how it helps protect the computer. Personally, I think that the password that is set in the BIOS does a better job of protecting the computer. It's just that the password set in the operating system can be hacked programmatically, but as far as I know, the BIOS password is not.
After pressing “Enter”, a window will appear in which you need to enter the password. I can enter a password of 6 characters. Thinking and remembering 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 setting, 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, look for the item “Password Check”. Opposite it, I had the “Setup” parameter set, which meant that the password was requested only when entering the BIOS. You need to change it to the value "Always". So we do, press “Enter” and select “Always”. All now the password will be requested both when entering BIOS and when starting the computer.
Now the most important thing, don't forget to save your changes. Press the F10 key and "Enter". The computer will reboot, and as soon as it starts to start, a window will appear asking for a password. We enter our password and press “Enter” (sorry for the quality of the photo).
That's all, the BIOS password is set, and your computer is now protected. Go ahead.
How to remove password in BIOS?
We set a password, now we will shoot :). It's not cracking (resetting) the password yet, it's removing it. Maybe you didn't like it, or you don't need it anymore.
We do everything the same, go into BIOS, select “BIOS Setting Password”. A window will appear with 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 again "Enter". That's it, the password has been removed.
How to reset the BIOS password?
First, we set the password, then deleted it, and now I will tell you how you can reset the BIOS password, that is, hack it. But this is not advice for hacking other people's computers, this is so that you can reset your password if you suddenly forget it.
As I wrote at the beginning of the article, resetting a password on a regular computer is easier than on a laptop. Just in order to reset the password that is set in the BIOS system, we need to reset the BIOS itself. Read the article for details on how to do this. There you need to either close special contacts, or pull out the battery for a while. After that, the BIOS parameters will be reset, and the password will disappear with them. In laptops, everything is the same, it's just more difficult to disassemble it.
Well, it seems to have written everything, try it, just look carefully and do not press anything extra, otherwise you will do business. Good luck!
Hi all! Accidentally found a way to reset the BIOS password in a laptop without disassembly. After all, it is very convenient!
How to remove the bios password in a laptop?
All BIOS settings information is stored in a chip on motherboard, and the battery on the board serves to store the information of this chip when the laptop is turned off from electricity or the battery is dead. And in order to reset this information, you need to disassemble it and pull out the battery or solder where it is soldered. Is it really uncomfortable?
bios password generator
Therefore, I propose another way, without disassembly. I found special program and translated it into Russian for you to make it convenient to use. and see the field in which you need to enter your code.
You can recover the password from laptops: Acer, Compaq, Dell, Fujitsu-Siemens, HP, Compaq, Insyde H20, Phoenix, Sony Vaio, Samsung. I'm not sure what will work on Asus, but try it.
Procedure
- We turn on the laptop and try to enter the BIOS, usually the F2 key.
The message enter your password appears.
Enter any character set and press enter. An invalid password box will appear.
We type 2 more random numbers and the BIOS will prompt you to enter a password to unlock or continue to boot the system.
We choose to enter the unlock password (Enter Unlock Password).
A password will appear that you need to enter in.
In the service, enter this code and click get password.
Depending on your laptop company, enter the received code in the proposed field.
And press Enter. And we get into the bios.
Now go to the Security tab and remove the password. Press enter against the set supervisor Password field and enter the password that we generated in the service, and do not write anything in the second and third fields, just press enter.
And now we do the same in the Set HDD Password field, remove the boot password hard drive.
Everything, the password in the laptop has been removed from the BIOS.
First and foremost. Service center "WnA|Service" is not responsible for the legitimacy of the acquisition of equipment by the user of the master password generator.
Second and no less important. This service is intended ONLY for personal use and prevention of your own forgetfulness. Any commercial use (read profit making) is not allowed in all manifestations.
Third, discretion. If you find the results of the password generator useful, you can post a link to home page service center in the anchor "laptop repair" (something like that).

Passwords on Acer, HP, Compaq, Fujitsu-Siemens and other Phoenix laptops
After three incorrect attempts to enter the password, it displays the message "System disabled ", where "12345" are arbitrary numbers. Generated by brute force (i.e., different for each request), it may be necessary to generate several times.
Passwords on laptops HP, Compaq (new + mini)
After three incorrect entry attempts, codes of the form are issued: "ABC1234DEF", - ten letters / numbers.
Passwords on laptops using BIOS Insyde H20 (HP, FSI, SONY, NEC)
After three incorrect entry attempts, codes of the form are issued: "12345678", - eight digits.
Passwords on Fujitsu-Siemens laptops
After three attempts to enter, codes of the form are issued: "ABCDABCD" - eight letters, "AAAA-BBBB-CCCC-DDDD-EEEE" - five groups of four letters, "1234-1234-1234-1234-1234" - five groups of four digits .
If after three attempts the code did not work out, you can try using the following algorithm. In the first attempt, enter (without quotes in all three attempts) "3hqgo3", in the second - "jqw534", in the third - "0qww294e". A code of the form five groups of four digits must be generated.
Passwords on DELL laptops
The following suffixes are supported: -595B, -D35B, -A95B, -2A7B. BIOS passwords like "1a2b3c4-595B" are seven letters/numbers with a suffix at the end. In case the letters/numbers are less than seven, they use asterisks up to seven characters from the right, i.e. service tag "1a2b-595B" must be of the form "1a2b***-595B". Passwords for HDD of the form "1a2b3c4d5e6-595B" - eleven letters/numbers with a suffix at the end. In case there are less than eleven letters/numbers, they achieve "asterisks" up to eleven characters from the left.
Passwords on Samsung laptops
After three attempts to enter, codes of the form are issued: "1a2b3c4d5e6f7890" - sixteen letters / numbers.
Passwords on SONY laptops
Only for laptops with BIOS Insyde H20 (SZ-series, possibly others). After three incorrect entry attempts, codes of the form are issued: "12345678", - eight digits.
The most common way to reset or clear the BIOS password that most of us know is to physically power down the computer by unplugging all cables and removing the battery from the motherboard for a few minutes.
Another way how to remove bios password- switch the CMOS jumper on the motherboard itself, if it is present. These methods work because most PC motherboards and some laptop motherboards use a battery to maintain BIOS/CMOS settings. If you turn off the power, BIOS settings/CMOS and password will be removed.
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 work. Click on the link below for a list of all known backdoor passwords. Before removing the BIOS password on a laptop, please note that passwords are case sensitive.
Default BIOS backdoor passwords
If you can boot Windows
CMOS De-Animator is a more modern tool than 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 have to do is run the tool as an administrator ( click right click mouse and select the menu item " Run as administrator» ) and press the button Continue”, and then restart your computer. When the PC boots up, you will see a CMOS checksum error and be able to access the BIOS without a password. The way CMOS De-Animator works is that it invalidates the checksum CMOS system memory. This resets all settings to default and clears any stored BIOS passwords.
CMOS De-Animator includes a backup and restore feature. This provides an additional guarantee of security. If something goes wrong when resetting passwords, the data is saved to a file with the .dea extension. The authors of the program warn about possible problems when used on laptops. The program sometimes causes antivirus software false positives and warnings on sites such as Virus Total.
If you cannot 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 of desktop computers for a few minutes should remove the BIOS password. But this is much less likely to work on a laptop. For additional security Notebook BIOS passwords are usually stored on a separate EEPROM chip that is independent of the BIOS battery.
If you entered the wrong BIOS password on the laptop several times, a message will appear on the screen stating that the laptop is locked. You will see something like “ System Disabled" or " Password check failed. System Halted” and some 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 the BIOS backdoor 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 get possible passwords based on the entered number. Just enter it and click the button. Then check the results and note all the passwords that are close to your laptop model.
Before removing the password from the BIOS on the computer, try the received codes for the locked BIOS to see if it works. Depending on the 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 on this site didn't work for you, check out Dogbert's blog for 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 type in the number and press Enter . You will receive a master password with which you can try to unlock your computer.
You need to run a master password on a computer that can boot into Windows and that has .NET installed. If you don't know which tool to use, you can try everything until you find one that matches 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 with a higher priority. In this case, you need to insert a CD or flash drive and the device will boot from them automatically. Also, booting from CD or USB may be set to a lower priority than hard drives. In this case, you will need to temporarily disable the hard drive.
How else to remove the password through the BIOS? If you have access to Windows, another solution to allow 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 password of a user or super user stored in the BIOS, regardless of the brand of the device. Supported BIOS list includes Award, American Megatrends (AMI), Compaq, Phoenix, Samsung, IBM, Compaq, DTK, Thinkpad, Sony, Toshiba. So there's a good chance your BIOS is on 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 a list of possible passwords. If unsuccessful, you can remove the password using two options, the second of which will completely reset the BIOS settings to their default values - you will have to reconfigure them later.

CmosPwd by CGSecurity
This is one of the most modern and popular CMOS decryption tools, although it was released quite a long time ago - in 2007. CmosPwd decrypts the password stored in CMOS and displays it. The following BIOSes are supported:
- ACER/IBM BIOS ;
- AMI BIOS;
- AMI WinBIOS 2.5;
- Award 4.5x/4.6x/6.0 ;
- Compaq (1992);
- Compaq (new version);
- IBM (PS/2, Activa, Thinkpad);
- Packard Bell;
- Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107;
- Phoenix 4 release 6 (User) ;
- Gateway Solo – Phoenix 4.0 release 6;
- Toshiba ;
- Zenith AMI.
Using CmosPwd, you can also remove the password from the BIOS on Lenovo laptop, create backups, repair, erase or even completely clear CMOS. When downloading, select 9. Next- 2. BIOS/CMOS Tools- 2. BIOS Cracker 5.0 (cmospwd). There is also a version that can be run from Windows.
!Bios by Eleventh Alliance
Allows you to perform backup and BIOS recovery. There's even a Blaster option that can clear certain parts of the BIOS, with the intention of removing the password - a powerful and potentially insecure option as it can damage the BIOS. !Bios can crack passwords used in some common BIOS versions including various versions IBM , American Megatrends (AMI) , Award , and Phoenix . This is an old tool that appeared in the late 90s, so it is unlikely that it will be able to work effectively on modern computers.
The password to enter the BIOS is one of the ways to protect information on PCs and laptops from unwanted access by outsiders.
Without a password, if it is set, you will not only be unable to change the BIOS Setup settings, but also boot the operating system.
It will also fail to start the computer from external media.
Forgetting the password is like a disaster, because it will become impossible to use the car. The only thing that will help you out in such a situation is its reset, or rather, zeroing.
Reset BIOS password on PC
Resetting the BIOS password on a desktop computer is not a problem. It is reset when the CMOS flash memory is cleared - a small 32-foot PLCC chip on the motherboard that stores BIOS settings.
Cleaning is performed in many ways, but since the BIOS Setup entry is closed for us, and operating system does not load, consider only the hardware ones.
Attention! Before following the instructions below, unplug your computer from the electrical outlet.
- Method 1: Temporarily remove the flash memory battery. The CMOS memory is powered by a CR2032 coin cell battery (numbered 1 in the photo below), which is also located on the motherboard. Remove it from the nest and install it in place after 15-30 minutes.
- Method 2: closing the Clear CMOS contacts with a special jumper - a jumper (in the photo below under number 2). These contacts are usually located not far from the battery and, in addition to “Clear CMOS”, they can be marked as “CLRTC”, “Clear RTC”, “CLR CMOS”, “CRTC”, “CCMOS”, etc. In working condition, the jumper is in position 1-2. To clean the flash memory, move it to pins 2-3, wait 30 seconds and put it back in place.
- Method 3: pressing the “Clr CMOS” button, which on some high-end motherboards replaces the jumper.
After restarting the PC, the BIOS password will be reset and the rest of the BIOS Setup settings will return to their original state.
Reset BIOS password on laptop
Things are more complicated with laptops, but there are more ways to reset the BIOS password on them. One is similar to the one described above, but it does not always help out. Why:
- To get to the battery or the “Clear CMOS” jumper, sometimes you have to disassemble the laptop completely. Only on some models the battery is located under a separate cover.
- The battery can be soldered to the motherboard, and the jumper can be missing.
- The BIOS password is sometimes stored in a separate EEPROM volatile memory chip, and manipulations with the battery lead to nothing. This is how business class laptops and some compact models are usually arranged.
If the latter - and this is your case, resetting the BIOS password can only be done by flashing the EEPROM on the programmer or by selecting a master password - a universal code suitable for a specific brand of laptop.
The option with a programmer is clearly not for home users. Repairmen come running to him. service centers when more simple methods don't help.
At the same time, the microcircuit is unsoldered from the board, “poured” into it new firmware and soldered into place.
After that, using the BIOS editor, enter the MAC address into the firmware and serial numbers laptop.
It turns out that the selection of the master password is the only thing that can be done at home. At different manufacturers laptops do it differently.
The essence of the method is as follows: after several unsuccessful attempts to enter the BIOS, it issues a certain code, on the basis of which a master password is generated.
As generators, programs (not widely used) and web services are used.
Sometimes the technical support service of the machine manufacturer helps to solve the problem, but, unfortunately, some require a fee for this.
Consider how to get a master password on laptops of the most common brands.
Asus.
Undocumented Feature: Resetting the BIOS settings and password on some models is done by pressing the Insert key at the same time as the power button.
In other cases, after a three-time failure to enter, the BIOS displays the date of its installation on the screen. Each date has a specific password associated with it.
To get started, try to find a master password on the Internet by date, fortunately, users are willing to share them. If it doesn't work, use the generator service.
Acer.
Three failed input attempts result in the message “System disabled [number_code]”.
The code is used to generate. Since it changes every time the laptop is turned on, it is not possible to find a suitable master password on the Internet, as for Asus. Sometimes you have to generate several times.
HP, Lenovo.
Different BIOS versions of HP and Lenovo laptops display different messages. Some are the same as those of Acer, others are an eight-digit numeric code, and others are a ten-digit alphanumeric code.
The code is passed to the generator. Most often, a suitable variant is not generated on the first try.
Outcome
Try it, and sooner or later you will succeed. But it’s better not to put a password on the BIOS without special need, or write it down on paper and store it in a safe place.
