BIOS Password Recovery for Laptops. Quick and easy way to recover BIOS passwords on laptops. Based on research by Dogbert and Asyncritus.
You are suggested to create an administrator account, change it, remove or even can reset the password for any other account. To do this, go through below guidelines: Open up the Computer Management panel and navigate to the “Start - Control Panel - Administrative Tools – Computer Management” icon. Choose the type of account which you wish to change or even reset its password by clicking the “Expand System Tools - Expand Local User and Groups - Click Users folder - click the user on right panel” folder.
Reset the user password by right clicking a user’s right panel to select the “Select Set Password - Click Proceed – Input the new password” menu. Tap the “OK’ button. For More methods to reset bios password visit:. On the newer laptops I've serviced there is no BIOS reset and pulling the CMOS battery does nothing. I've seen some with what looks similar to solder pads labeled as CMOS reset, but they won't work in most cases. My suggestion, try the password three times, and a dialog box should pop up with a code. Punch in the code to unlock the bios here.
This has worked on every laptop that I've serviced, even new models. However, if a drive is protected at a bios level, for security, you cannot unlock the drive (this is put into place in case the drive is stolen). ALMOST FOOLPROOF METHOD for older ACER (and other) laptops. Required tools: -USB to SATA connector (or any old USB to SATA harddisk case ) - spare SATA laptop hard disk (any size.) WIN32DISKIMAGER FREEDOS clnpwd.exe Download WIN32DISKIMAGER from the web at or have a linux system ready with DD Download FDlite.zip from extract and remember where the 32MB FD12LITE.img is. Download clnpwd.zip from somewhere and extract clnpwd.exe from it take a small SATA hard disk and write the image FD12LITE to it using WINDISKIMAGER (or Linux DD.) copy the file clnpwd.exe to the hard disk. Put the just created hard disk and put it in your ACER (5310 etc) wait till the HD has booted, stop the install and run clnpwd once or twice to clean system and/or user password.
Not useless at all. What the author is describing is a method to use if the one time boot menu option (F12 on an Acer) has been disabled in CMOS as well as a BIOS PWD set. Alternatively, if USB HDD has.not. been disabled in CMOS you can make a DOS bootable USB thumbdrive using RUFUS (using the freedos method) ( ) You would first physically remove the HDD from the system This will force the system to boot from another valid bootable source.
In this case USB HDD. Then just copy the clnpwd.exe to the root directory of the bootable thumbdrive. Put the thumbdrive into a USB port and boot the system. It should bring you to a DOS prompt.
Type DIR - ENTER. Now clnpwd.exe should be visible in the root directory. Type the file name - ENTER and choose option 1, 2, or both one after the other. Reboot, hit F2 and you should be in the CMOS set up without requiring a password. Worked for me:). When it is required, if you know your BIOS password it can be removed by following the steps below.
Removing a BIOS password: Power on the system. As soon as the first logo screen appears, immediately press the F2 key, or the DEL key if you have a desktop, to enter the BIOS. Use the arrow keys to navigate to Security or BIOS Security Features.
Highlight Set Supervisor Password or Change Supervisor Password and press the ENTER key. You will be prompted to enter your current password. After you will be prompted to enter a new password, and a second time to verify it. To remove the password, leave these two fields blank and press Enter. Press ENTER to confirm password creation. A message will appear stating Changes have been saved. Press ENTER to continue.
Press the F10 key to save changes and restart the system. This is the only 100% working solution: hashes and all childish stuff described in here and everywhere do not work for Acer W510/511. Their BIOSes completely locked by Acer. There is no battery (eprom), no hashes - nothing to do as you could do usually in such case. Thats because of Acer do really intended to charge you with 100 bucks for solution of these stupid problem. But, fortunately there is existing much more better alternative, please follow. All you need is a flash drive formatted as FAT32 and 20 bucks.
Hi experts, I have an Acer Travelmate 8571 laptop and forgot my BIOS Password, so laptop is not starting up. I removed the CMOS Battery for 30 minutes, but no joy:( So when i press F2 during startup, its still asking for a Password. When i dont press F2 during startup, it then gives error reading boot configuration ( Boot BCD). When i put a windows install CD, it wont startup with install CD, but its trying to read the info from the hardisk where most probably the boot section is faulty. So i cant go into BIOS to change the setting to boot from CD, because i dont have the BIOS password. So i am totally stuck.

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.
