We have a list of default passwords used by BIOS, free tools to. Unlock or Reset BIOS Security Password. Laptop brand and download a separate master password.
Any amateur computer technician should know how to reset BIOS passwords that can be setup from within the BIOS because there are times when they need access to change some configuration options such as the boot order. If a password has been set, you cannot enter the BIOS or sometimes even boot the computer itself unless you know it, and this can be a real headache if nobody knows what the password is. It’s becoming increasingly common due to the amount of computers changing hands these days and previous owners have set a password and not passed on that information. The most common way that most of us know for resetting or clearing the BIOS password is to physically remove the power from the computer by disconnecting all cables and removing the battery from the motherboard for a few minutes. Another way is to short the clear CMOS jumper on the motherboard itself if one is present. These methods work because on most desktop and a few laptop motherboards, a battery is used to sustain the BIOS/CMOS settings. By cutting off the power, the BIOS/CMOS settings and password will be erased.
If for some reason you’re unable to reset the computer’s BIOS security password by removing the battery or clearing the CMOS jumper, and you don’t know what the password is, here are several options which you can try out to clear it. Generic Backdoor Default Passwords Before using any tools that try to reset or make changes to your BIOS, it’s worth seeing if any of the well known backdoor or default passwords that have been around for some time work. Click on the link below to view the list, the passwords are case sensitive.
If you can Boot into Windows CMOS De-Animator is an up to date tool compared to the majority of BIOS hacking/resetting tools out there, and can reset the BIOS password from within Windows. The latest version 2 executable of CMOS De-Animator is compatible with both 32-bit and 64-bit operating systems.
All you need to do is run the tool as administrator (right click - “Run as administrator”) and click the Proceed button followed by restarting the computer. When your computer boots up, you should see a CMOS checksum error where it allows you to access the BIOS without a password. CMOS De-Animator works by invalidating the checksum of your system’s CMOS memory which resets all settings to default and clears any stored BIOS passwords upon reboot. CMOS De-Animator also has a basic backup and restore option to give you that extra little bit of added security, the file will be stored with a.dea extension. Do take note of the authors warnings about the problematic nature of using the program on laptops and that usage of CMOS De-Animator is at your own risk. Because of its nature the program will sometimes trigger false positives in antivirus software and on sites like Virus Total. If you Cannot Boot From Hard Drive or CD Although disconnecting the power and removing the battery from the motherboard on desktop computers for a few minutes should remove the password, this is much less likely to work on laptops, but it’s still possible on some older models.
For extra security the passwords for laptops are usually stored on a separate EEPROM chip which doesn’t rely on the BIOS battery and is unaffected by cutting the power. If you enter the wrong password a few times on a laptop, there will be a message that the laptop is locked. You will be presented with something like a “System Disabled” or “Password check failed.
System Halted” message with some numbers. If this message appears while entering the BIOS you can simply power off and on the computer to remove it and try again.
Take note of the number because it’s a valuable piece of information and required to generate the BIOS backdoor password to get back into the laptop. All you need to do is to have the number to hand and then visit the webpage.
This website has been setup to let you easily get the possible passwords based on the number entered, simply enter it and press the button. Then look at the results and note all the passwords which are close to your model of laptop. Try the codes on the locked BIOS message to see if it works, depending on laptop models you may need to press Enter or Ctrl+Enter after entering the code.
The codes used are based on the work of “Dogbert” who’s done a lot of research and created a number of small utilities and also Python scripts for unlocking several different brands of laptop. If the website above or its codes don’t work, visit where you will be able to find more details about your laptop brand and download a separate master password utility for it. To use one of the programs, simply download the correct one for your laptop and run it, then type in the number and hit enter. The master password will be displayed for you to try and unlock the computer. You have to run the master password tool on a computer that can boot into Windows and has.NET installed. If you don’t know which tool to use, it’s safe to try all of them until you find the one that matches your laptop.
There are a number of other reset BIOS password solutions on page 2. My understanding of your problem is you have a user account you cannot access and your partitions are not setup properly. This has nothing to do with CMOS, however. Using a boot disk for another operating system, backup all of your personal files, reinstall windows and then restore your personal files. There are several tricks you can use to gain user access to the system, the most notable being the sticky keys method.
If sticky keys is enabled on your machine this should work. First, go to the system32 directory in the windows system files, from an OS boot disk where you can access the windows drive.
You have to rename the sethc.exe to something else (Dont delete it) and then make a copy of cmd.exe and rename it to sethc.exe. Once this is done boot into windows and press shift 5 times to bring up a console, where you can use the net user command to create a new user or change the password.

But with just a little work you can cure it yourself. Well maybe, sadly passwords for many newer laptops cannot be generated yet. There are several password generators on the web that work great.

There are some very smart people that have combined all the generators into one. Can’t list them all but here’s the two I normally use. First, Dell owners by aware that free generators do NOT work for the following: Service tags ending with -3A5B, -1D3B, -1F5A, PPID #s and System disabled codes that are larger than 5 digits Dell by service tag When a rude screen pops up saying it is protected by a password for Service Tag # (example: 1A2BC34-595B), This is a bios password. Will be 7 char with 4 char suffix. Enter that into generator using all capital letters. Click Generate and use password listed under “Dell by serial number”.
Can do the same with hard drive passwords (example:.12AB34C5-595B) Notice it has 11 char with 4 char suffix. If it displays stars then use them. If it has a suffix of -1D3B or -1F5A, then you’re out of luck.
They are to new and the free generates will not work yet. Important Input instructions: Passwords are for QWERTY keyboard only (standard US). Case sensitive. Some units only require pressing after password, some require pressing + after password and some require holding down while pressing once or twice. Dell, Acer and some others with generic Phoenix bios If you get a plain screen that just says Enter Password then enter 3 wrong passwords and a System Disabled code will pop up(example: 12345). Don’t worry, just shut down computer, restart and the disabled thing goes away.
Now enter that number into generator, click Generate. Write down the top password generated.
Click Generate several times (maybe 5,6 or more times) and write down password after each time. Try each password on your machine until you hit one that works by entering password and pressing. The same can be done for hard drive password, be aware that it does not always work for hard drives. Sony READ Dogberts Blog above.
