There are a few software which can also reset CMOS settings or BIOS password or both within a few clicks. But as stated above you should have access to a system which is turned on and should have access to MS DOS or MS Windows:

Need to access your BIOS but don`t have the password , use CmosPwd

Hope someone can help, I need to remove a BIOS password. Does anyone have any experience using cmospwd on HP (or any) laptops? I'm unsure about using it, I've seen some people say it can brick a laptop due to RAM configuration and something to do with the proprietary mainboards.

I need to remove a BIOS password from an HP Pavilion 15 aw084sa but unfortunately I get an alpha-numeric (apparently the numeric code encrypted) checksum after failing the password 3 times, so I can't use the generators like bios-pw . org . I've seen somewhere that apparently you can press one of the Function buttons (F2??) to display the checksum numerically but it hasn't worked for me.

On laptops, the password is usually stored in an eeprom on the motherboard and not in the cmos. You need an eeprom programmer/eeprom reader (electronic device) to retrieve the password.If you erase the cmos (ie. cmospwd /k) and if the password is really stored in an eeprom, you won't be able to boot anymore.

You can get/buy eeprom programmer in electronic shops or labs, you need another PC to use it.You can desolder the eeprom with hot air or you can try to "clip" the eeprom. With the eeprom programmer, backup your eeprom and run cmospwd /d /l eeprom_backup. If you don't see the password, you can tryto fill the eeprom with zero or FF, don't forget the reset the cmos.

I've been trying to reset the bios password on an old Acer Aspire laptop. I've been looking for a while until I stumbled upon cmospwd. I downloaded it, and it asked me to "run ioperm -i as administrator first" Upon running ioperm -i, I received a message stating "StartService function call failed". I couldn't find anything helpful on this error, so I decided to come here. I did find some info from replies on this post, in response to someone stating that they got the same error as me. They said they tried running ioperm manually with net start, but it said system error 2, system cannot find the file specified. Someone responded to this stated that ioperm is 32-bit only and my only other option would be to run it off a Live CD of Linux, but I'm pretty sure my laptop is 32-bit, and the reason why I need into the bios is to enable the Boot Device option, so using a Live CD is out of the question.

I'm trying to access my BIOS settings but it needs a special password which I don't know. It doesn't give me any code after I fail 3 times, it just locks me out and I have to restart my pc again. I am way too incompetent and fear damaging my PC so I don't want to touch anything inside the PC itself, especially stuff like the motherboard. Is there any way I can reset or find out my password?

Hey guys... I have a Dell Studio 1737 that I purchased from Dell Outlet a little over a year and a half ago. I am about to sell it, and as part of my cleanup I noticed it has a BIOS password set (supervisor password) so that whenever I try and access the BIOS it prompts me for the password. (not boot or HDD password).

Now, onto my question... From my research I have read that Dell BIOS passwords are actually stored in EEPROM. I have already tried removing the motherboard coin battery for 24 hours and all that did was make the system clock off. BIOS supervisor password was still there. I tried a few free apps that I found (CMOSpwd, WinBios1.2, etc)... I think these programs don't have read access to EEPROM (or whatever the password data is stored on). I also tried a bunch of the "default" backdoor passwords, none of which worked.

that 5 digit error code (phoenix bios) is what is used to calculate a master password for your Dell, most Dell's use the 7 digit service tag to calculate the master password. yes it easy and can be done just like Dell does it. send me a email: I'll help you out.

The bios can be protected with a password to prevent third parties from accessing and modifying its settings. You have to enter the password to access it, and if you can't provide the correct one the access gets denied. This can be useful if you want to prevent users from booting from CDs or USB devices among other things.

The following method describes a way to recover the password if you forgot it or bought a used computer with a set bios password, or if you are working in a company and need to get into the BIOS but the records of the password are no longer available.

Once the disk is created copy the contents from the dos folder of cmospwd to the disk and restart the computer. You will have to remove all hard drives from the system if you do not automatically boot from disk drive. Type cmospwd.exe in the command line and the password should appear. Ignore the information about the other bios manufacturers and take a look at the one your computer is using.

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

4.- Reboot your computer and pay extra attention as to what kind of BIOS you have, look for the BIOS word and the word right beside it, write the BIOS name and write it down since you will be needing that later.

9.- Finally it will show the commands that it can do like backup,restore, Etc. however if you don`t wanna do all those things or find them too complicated just type cmospwd / K this will attempt to clear the BIOS erasing the password, however keep in mind that this will also erase all of the BIOS settings that are critical to the functioning of your computer so you will probably want to enter the BIOS and load the optimal values so that you can keep using your PC.

Hi to all.

I have a problem. I have a bios dump locked with password.

I cleaned the ME region and reflashed the bios, but the password is still there.

Maybe the password is not stored in the ME region?

Thanks

@Rob983 - please edit your posts if you want to add more info and no one has replied yet, thank you.

If you have a locked BIOS and unlocked BIOS, put those into a zip for me and I will see if I can find the area to remove the password for you.

* Edit - Sorry, I missed your last post while editing and replying. So, you got it correct?
If yes, please still upload those BIOS for me, so I can find the location (or you tell me hex address) then I can find what actual area in BIOS modules or NVRAM it is, then I can post the info here to help others later so they know where to look.

In this article, we will explore 3 proven ways to crack BIOS password and regain access to your system. With these expert methods at your disposal, you can confidently tackle the challenge of a lost or unknown BIOS password and take back control of your computer. Let's dive in!

Some BIOS? have pre-installed backdoor passwords that enable access to the system if you have lost or forgotten your password. Attempting to regain access to the computer by using one of the following backdoor passwords should be your first step if you have lost or forgotten your BIOS password and cannot boot your computer. If you are able to regain access to your system by using a backdoor password, you can then use a password cracker to reveal the stored password or enter the BIOS setup to change the password. These backdoors are more likely to work on older desktop systems. We are not aware of any name brand laptops or notebooks that have backdoor BIOS passwords.

Assuming you have access to a decrypted ROM image, you might get a head start by scanning for a block of bytes that are statistically random. You should expect to find a series of exactly 20 (SHA-1) or 32 (SHA-256) bytes. Then, if you can find a reference to that location, you might have a quick place to set a breakpoint to prove your theory.

I have gotten this IPC UnoSys 286 and can't find the factory bios password.
I haven't been able to find the pc on google so I hope anyone from here knows anything about this pc.
Normally I wouldn't really care about this but it's blocking access to dos or whatever this pc has installed.

Looks like the manufacturer deliberately set a default password. You will need to guess it (did you try IPC or Intelligent Personal Computer?), or dump the BIOS and try to find what it expects using a disassembler, or try a different BIOS from another 286 board. Try to boot it from floppy, if that works you have a mostly functional PC.

CAUTION! The WD Security software uses your password to electronically lock and
unlock your drive. If you forget your password, you will not be able to access the data
that is on your drive or write new data to it. You will have to erase the drive before you can use it again.

Unfortunately for the safety of your own files you cannot get into the drive again without the password to access the files. One would need to wipe the drive completely for it to be useable again. This is for the best. Certainly you would not want anybody to be able to get their hands on your data by resetting such a password without your permission.

To recover the password, you need to note the value to the right of the BIOS you have installed and then you have to type in cmospwd /m[xxx] to execute the module. If that doesn't work, you can kill the BIOS using the /k switch.

Since using the program is a bit complicated, make sure to read the instructions provided beforehand. But if you need to recover Windows login password, then you can get Password Recovery Bundle to recover your lost or forgotten Windows admin/user passwords.
