How to find out the bios password for a laptop. How to reset BIOS password on computer and laptop. BIOS Engineering Password
Today we'll talk about how to reset BIOS password on the motherboard of a laptop or computer. If you suddenly forgot your password, then logging into the system will be problematic.
In this case, you might think that the motherboard needs to be replaced, but this is not the case. Developers have long deliberately implemented ways that you can quickly and easily disable the password in the BIOS. Absolutely everyone can find themselves in such a situation, for example, if you set the password yourself, there is a backup code, or protection was already enabled when buying a computer from hand.
Will start command line, where you can see what commands are available in this utility. For this, we introduce the following - cmospwd_win.exe /?.
To reset the BIOS password, enter the following command:
cmospwd_win.exe / k
To confirm clear CMOS action enter number 1 and press Enter.
The program can be easily used not only in Windows, but also with bootable USB drive DOS. Initially, it needs to be placed in the image.
Using the debug.exe tool on Windows
When using Windows XP you can use a special utility. This debugger can be found along the following path - WINDOWS \\ system32 \\ debug.exe... You can copy this address and start the debugger using the Run window, which opens with Win + R.
Also, the run window is located along the path: Start -\u003e Run.
To reset the BIOS password, you must enter commands for different versions of I / O systems:
AMI BIOS:
- -o 70 10
- -o 71 0
- -o 70 11
- -o 71 0
AWARD BIOS:
- -o 70 17
- -o 71 17
Phoenix BIOS:
- -o 70 ff
- -o 71 17
After each entered line, you must press Enter. Also, the designation of these codes is as follows:
- q - exit;
- the first number is the port;
- the second number is the number of bytes.
To remove the BIOS password, there is more than one utility. Now I will explain how to use the PC CMOS Cleaner tool, which can easily reset the CMOS BIOS password, restore the settings to the factory state.
Brand motherboard or laptop is not at all important, since the program supports almost all BIOS versions. There is also support for 32x and 64x processors.
This method works well on modern motherboards and laptops. To implement this method, you will need a smartphone or other computer with Internet access.
So, all you have to do is enter the password incorrectly three times. After that, a message will be displayed on the screen that the system is disabled, as well as a special code.
If you have acer laptop, as well as access to the operating system, then you can easily remove the BIOS password using the built-in utility Acer eSettings Management... If you have it, great, and if not, download it from the official + Acer Empowering website.
- Launch the Acer eSettings Management tool from the Start Menu or Desktop. The program is usually located under Start - All Programs - Empowerment Technology - Acer eSettings Management.
- Find the item "Passwords BIOS".
- Click on "Remove Password" to restore access to the BIOS. You can also create it.
Check with your motherboard or laptop manufacturer
If the above methods did not help you remove the password from the BIOS, then the only option is to write an appeal to the device manufacturer. After all, only they know how to properly clear CMOS memory and return the BIOS to its default state.
In addition, you can contact service centerbut you have to pay for the services. To reset the BIOS password, the service has special tools... It is possible not only to clear the password, but also to replace the BIOS chip with a similar one.
I hope these methods helped you and you reset your BIOS password on your computer or laptop. Be careful the next time you set a new password.
Hi everyone! I accidentally found a way to reset the password from the BIOS in a laptop without disassembly. It's very convenient!
How to remove the BIOS password in a laptop?
All information about BIOS settings is stored in a chip on the 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 to reset this information, you need to disassemble it and pull out the battery or unsolder where it is soldered. Isn't it inconvenient?
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 we see the field where you need to enter your code.
You can recover your password from laptops: Acer, Compaq, Dell, Fujitsu-Siemens, HP, Compaq, Insyde H20, Phoenix, Sony Vaio, Samsung. On Asus, not sure which will work, but try it.
Procedure
- We turn on the laptop and try to enter the BIOS, usually this is the F2 key.
A message will appear enter your password.
We enter any set of characters and press enter. An incorrect password sign will appear.
We dial 2 more random numbers and the BIOS will prompt you to enter the unlock password or continue booting the system.
We choose to enter the unlock password (Enter Unlock Password).
A password will appear that must be entered into.
In the service, enter this code and click to get a 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. We press enter on the opposite of the set supervisor Password field and enter the password that we generated in the service, and in the second and third fields we do not write anything, just press enter.
And now we do the same in the Set field HDD Password, remove the download password hard disk.
That's it, the password in the laptop is removed from the BIOS.
Most personal computers do not have BIOS passwords because the feature must be manually enabled by someone. However, many corporate machines have BIOS passwords set for security reasons, and if you are reading this post, you probably realized that breaking a BIOS password is not easy. How to reset laptop BIOS passwords?
Can I download operating system or not depends on how many security settings have been enabled. In most modern BIOS systems, you can set a supervisor password, which simply restricts access to the bIOS utilitybut allows Windows to boot. The second option, commonly called Boot Up Password, or something similar, must be enabled so you can see the message before the operating system boots.
It's also worth noting that you might have to open your computer to try to bypass the BIOS password, and if you have a desktop, this is usually much easier. Not only is it easier to open the desktop, but finding the component to remove is much easier. In this article, I will talk about different ways bypass BIOS password and hopefully it works.

The easiest way to overcome BIOS password is to use backdoor password. Fortunately and unfortunately, BIOS passwords are not very well protected, and this is done on purpose so that technicians and others can help get into their computers.
This is good because it will probably help you access your computer, but it is bad because anyone who thinks a BIOS password is super secure is wrong.
Therefore, most BIOS manufacturers have fault tolerance when you enter the wrong password more than 3 times. For example, I have an Acer laptop at home and I went and set the BIOS password and then entered the wrong password three times.
After the third time, I received a message with the message “ System is disabled " but I also got the number displayed right below this post.
All you have to do is go to the site titled and just enter the number! It will show you a set of passwords for different brands of BIOS.
Also, don't worry about system-disabled messages, because these are just scary tactics. All you have to do is turn off your computer and turn it on again and you should be able to enter your BIOS password again without any problem. I was very shocked at how easily this worked, so this is the first thing you should try before hacking into your computer.
Step 1. Discover start menu "By clicking the button" Start" on your desktop.
Step 2: Go to All programs > Empowerment technology > Acer eSettings Management .
Step 3: Click " BIOS passwords " next to the screen footer.
Step 4: using the parameter " Create a password" or " Remove password " you can regain control.
Laptop BIOS passwords - Using computer hardware
This method involves working with computer hardware and components. Only proceed if you are confident enough to complete the task. It may also void the warranty period. The steps below are mentioned for both desktops and laptops.
Step 1: Unplug the power cord from your desktop or laptop.
Step 2: Remove your desktop case cover.
For a laptop, turn it upside down and remove the battery. Open the hard drive bay by sliding the cover. Unscrew and pull out hDD from your laptop.
Step 3: Find a coin-operated watch battery (also known as a CMOS lithium battery) and remove it. Store it aside for at least an hour.
For laptop, unplug the tiny power cord that connects the watch battery to motherboard... Keep it unplugged for at least an hour.
Otherwise, you can also find the BIOS reset jumper marked CLRP1. Move this jumper to the Clear position. Let it be in this state for at least an hour.
Step 4: after about an hour, replace the battery in the slot, or move the jumper back to the "execute" position.
Step 5: Replace the case cover and start the computer.
If done correctly, the computer or laptop should boot without prompting for a BIOS password.

Contact the laptop manufacturer
If the above steps do not help to remove the CMOS password for your laptop, we suggest referring to the steps to clear the password. Many manufacturers have strict policies to help protect their customers' laptops, and only they have information on how to clear CMOS passwords.
Service
For now, your only option is to use a professional BIOS password reset service. They have dedicated tools that they can use to actually remove the BIOS chip from motherboardas well as using the new BIOS, thereby removing the password, etc. This will probably cost you between 500 and 2000 rubles, depending on the company. Enjoy!
There are several ways to reset your password and BIOS settings if you've forgotten it. The first hardware method is suitable for desktop computers, the second - software will help to reset the BIOS password on laptops. Let's consider both options in more detail.
The situations are different. It so happens that your friend or acquaintance decided to change the configuration of his computer. I asked you to help him in this matter. You come to him, but it turns out that he does not remember earlier set password to enter the BIOS. Or you yourself, when, having started protecting your PC, set a password on the I / O system, and now you cannot remember it.
In such situations, only resetting the BIOS password can help. In this case, this can be done in two ways: reset bIOS settings using a special CMOS jumper on the motherboard (for this, the PC must be completely de-energized); take advantage of forgotten DOS commands through the command line interface.
Unlock BIOS on PC
If you reset the password and reset the I / O system settings, you need to desktop computerequipped with a modern motherboard, then for this there is special button “Clear CMOS”, however it is not found on all models. If this is your case, then just turn off the computer from the network, open system unit and click on this button. BIOS settings will be completely reset.
If the button described above is not on the motherboard of your PC, you will need to look for contacts with a jumper specially designed for resetting BIOS settings on it. They are easy to find, they are labeled CMOS. Disconnect the PC from the network and close the second pair of contacts with a jumper (jumper). After that, after about 10-15 seconds, return the jumper back to the first pair of contacts.
If you could not find this jumper, then you can reset the settings by pulling out the battery for 2-3 minutes.
Reset BIOS password on laptop
The three ways to reset your password described above are only suitable for desktops, but what if you are using a laptop? After all, there may be no jumpers on its motherboard? In this case, you need to find the documentation for your laptop and study it thoroughly in order to make sure that the jumpers and buttons on the mat. board no. What if there is something?
In the event that the manufacturer does not provide jumpers on the board, then you will have to use the software method to reset the BIOS password on the laptop. To do this, you need a DOS boot disk or installation disk Windows with command line boot capability. Also, if you can log into Windows under account administrator, then boot disks you don't need it.
So. Before us is the command line. Enter the debug.exe command in it and press “Enter”. Then, sequentially enter the commands:
o702E
o71FF
q
Note. After entering each command, press the “Enter” button.
That's practically all. After the PC restarts, a message appears on the monitor screen that an error has occurred in the CMOS. And simultaneously with this error, you will be prompted to check or perform BIOS settings. The BIOS settings are reset and you can continue, depending on what you need: restore the PC settings or change them.
The most common way to reset or clear the BIOS password, which most of us know, is to physically power off the computer by disconnecting all cables and removing the battery from the motherboard for a few minutes.
Another way how to remove password from BIOS - 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 / CMOS settings and password will be cleared.
If for some reason you are unable to reset your computer's BIOS security password by removing the battery or switching the CMOS jumper, here are a few options to try.
Default backdoor passwords
Before using tools that attempt to reset or make changes to the BIOS, it is worth seeing if any of the known default backdoors or passwords are working. Click on the link below to see a list of all known backdoor passwords. Before removing the password from the BIOS on a laptop, please note that passwords are case sensitive.
Standard BIOS backdoor passwords
If you can boot Windows
CMOS De-Animator is a more modern instrument than most instruments. 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 ( click right click mouse and select the menu item " Run as administrator» ) and press the button " Proceed"And then restart the computer. When the PC boots up, you will see a CMOS checksum error and will be able to access the BIOS without a password. The principle of CMOS De-Animator is that it invalidates the checksum CMOS memory system... This resets all settings to default values \u200b\u200band clears all stored BIOS passwords.
CMOS De-Animator includes a backup and restore function. This provides an additional guarantee of safety. 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 occasionally triggers erroneous antivirus software alerts and warnings on sites like Virus Total.
If you cannot boot from your hard drive or CD
How to remove BIOS password on samsung laptop? Power off and remove battery from motherboard stationary computers 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 usually stored on a separate EEPROM that is independent of the BIOS battery.
If you enter the wrong BIOS password on the laptop several times, a message appears on the screen stating 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 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 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 retrieve possible passwords based on the entered number. Just enter it and press the button. Then check your results and note any 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 check if it works. Depending on the laptop model, after entering the code, you may need to press Enter or Ctrl + Enter. 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 to unlock different models laptops.
If the codes obtained on this site did not help you, visit Dogbert's blog, where you can find more information about your laptop brand 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 under Windows and has .NET installed. If you don't know which tool to use, you can try everything until you find the 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 installed with a higher priority. In this case, you need to insert a CD or flash drive and the device will boot from them automatically. Boot from CD or USB may also be prioritized lower than boot from hard drives... In this case, you will need to temporarily disconnect the hard drive.
How else to remove the password through the BIOS? If you have access to Windows, another solution 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 of the tools you can use when booting from a CD or USB flash drive.

! Bios by Eleventh Alliance
Allows to execute backup and bIOS recovery ... There's even a Blaster option that clears certain parts of the BIOS in order to remove 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 different versions IBM, American Megatrends (AMI), Award, and Phoenix. This is an old tool that appeared in the late 90s, so it is unlikely to work effectively on modern computers.
