9 Ways To Reset / Remove BIOS Password For Lenovo, HP, Dell, Acer, Asus Laptops

Updated: June 4, 2019 / Home » Computer and Internet Security » Encryption, Password & Recovery

How to remove, reset or recover your forgotten Lenovo, HP, Dell, Acer, and Asus Laptops laptop BIOS password? There are many methods, each method has its own strength and weakness. If you forgot your BIOS password, chances are you don’t have access to your computer, not even in Safe Mode, therefore making this software useless. For Desktop user, removing the battery for 5 minutes will reset the BIOS whereas laptop user might not have the option without invalidating the warranty of the laptop, this is where software comes in handy.

On laptops, more often than not 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 try to fill the eeprom with zero or FF, don’t forget the reset the cmos.

↓ 02 – CMOS De-Animator 3 | Windows

CMOS De-Animator 3

CMOS De-Animator is a service utility for your system’s CMOS RAM. Unlike its predecessor, the CMOS De-Animator 2.0, the new version includes a graphical interface and CMOS-backup options along with the “Clear CMOS” procedure, which was the original version’s only purpose. So, you can now backup the main CMOS settings to a file, or restore them later. The application supports all 32-bit and 64-bit Windows operating systems except Windows 95 and Windows NT 3.51; for these old systems, you have to use De-Animator’s previous version.

Compared with CMOS De-Animator v2, the new features include an interactive new GUI, command-line support with optional silent (unattended operation) switch, log file generation, and experimental EEPROM / low level BIOS reading support! Original features – backup, restore and reset the CMOS RAM – of the old De-Animator are, of course, intact and still conveniently accessible. The same goes for extreme backward compatibility, just as with previous versions – the application runs on a Windows NT 3.51 just as fine as under Windows 8, 32-bit or 64-bit!

↓ 03 – CmosPwd | Windows | Linux

CmosPwd

CmosPwd decrypts password stored in cmos used to access BIOS SETUP. The software is also able to save the configuration of a BIOS, which protects the data by duplicating and storing it in a secure location on the hard disk. With CmosPwd, you can also backup, restore and erase/kill cmos. CmosPwd is free, it’s distributed under Open Source GPL. Works with the following BIOSes

  • 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

↓ 04 – !Bios | Windows

!Bios

!Bios ( a very old program, might work on older computers ) is a tool originally developed for a brute, blunt removal of passwords from BIOSes. Through it’s development it has been severly extended, and Eleventh Alliance have now recieved emails from computer support divisions, hackers and not least of all ordinary computer users who has expressed gratitude for what they consider one of the best toolkits available.

  • !Bios can decrypt the passwords used in some most common BIOS (including various bioses/versions by IBM, American Megatrends Inc, Award and Phoenix).
  • !Bios can also save and restore the IBM standard CMOS/NVRAM memory where almost all common Bioses store the BIOS setup settings.
  • !Bios can save the part of the RAM dedicated for the BIOS (which has security implications in some BIOSes as encryption algorithms and/or password may actually reside here in some badly coded BIOSes).
  • !Bios can do crude, brutal attacks (“blasters”) which removes password from a lot of Bioses. A bit dangerous though, can give unexpected and unwanted results.
  • !Bios has a CMOS editor where you through a interface with similarities to several hex-editors can modify the CMOS/NVRAM memory in binary, decimal and hexadecimal ways. (only adviced for very experienced hackers)
  • !Bios has a command line interface (CLI) and a very simple VGA-text interface, GUI. If no parameters is passed to !Bios, it starts the easy-to-use GUI, otherwise it starts the GUI.
  • !Bios has built-in support pages which provides several tricks and tips, notes about known backdoors etc.

↓ 05 – Clear CMOS Jumper or Dipswitch Settings

There’s a jumper on your motherboard that you’ll need to identify and remove. Most motherboards make your job easier by actually labeling the correct jumper as “BIOS config” or something similar. Remove the jumper, and then turn the computer on. In some cases, you will have to remove the jumper while the system is powered up, though to minimize risk, try doing this first with the computer off. In today’s quick tip I show off the quick and easy process of resetting the CMOS on your computer. Simply move the CMOS jumper to the last 2 pins for about 5-10 seconds depending on your motherboard, and then replace it back to it’s original position.

↓ 06 – Remove Internal CMOS Battery

Reset Or Remove BIOS Password For Lenovo, Huawei, Samsung, Acer, Dell, HP, Toshiba, Asus And Apple Laptop

For desktop user, open up your computer casing and look for the battery. Remove the battery for approximately 5 minutes (maybe longer, depending on the motherboard) and slot it back. By removing the battery and deprive the motherboard’s flash memory of power supply, you are essentially resetting the settings back to default when the existing data in BIOS are cleared. This method works well for desktop, however this is not practical for laptop user unless the warranty expired long time ago. This method might or not not work, it depends on the type of motherboard.

↓ 07 – BIOS Password Generator For Laptops

BIOS Password Generator for Laptops

How to Reset a Dell laptop BIOS Password? Quick and easy way to recover BIOS passwords on laptops, this site contains master password generators for various BIOS/UEFI firmware. Based on research by Dogbert and Asyncritus. When a laptop is locked with password, a checksum of that password is stored to a so-called FlashROM – this is a chip on the mainboard of the device which also contains the BIOS code and other settings, e.g. memory timings. For most brands, this checksum is displayed after entering an invalid password for the third time.

The dramatic ‘System Disabled’ message is just scare tactics: when you remove all power from the laptop and reboot it, it will work just as before. From such a checksum (also called “hash”), valid passwords can be found by means of brute-forcing. Works on Fujitsu-Siemens, Dell, Compaq, Acer, HP Hewlett-Packard, Sony, Samsung and more.

↓ 08 – Using MS DOS Command | Require Access To The Computer

MS DOS Bios Password Reset debug o 70 2E o 71 FF quit

This method works if you have access to Windows because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands:

    debug
    o 70 2E
    o 71 FF
    quit

Important – The first character in the above commands is English alphabet “o” and not the number 0. Now, after providing the above commands in MS DOS, restart your system and it should automatically reset the CMOS Settings along with the BIOS password. How does it works? In this “MS DOS Debug Command” method, the “o” character present at first in these commands, outputs the values to IO ports. The number 70 and 71 are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS settings as well as BIOS password.

↓ 09 – Backdoor Password By Manufacturer

Some BIOS manufacturer or the laptop maker put a backdoor password in BIOS and will always works regardless of what password you have set in the BIOS. It is a master password which is used for testing and troubleshooting purposes, or in the even you lock yourself out of your own laptop.

↓ Note

The BIOS is the basic instruction set that “teaches” the computer how to access its media. If the BIOS is password protected, the computer will not function without the password. BIOS passwords are used in two ways: To prevent modification of the BIOS settings and to completely stop the computer from booting.

If you’ve got crucial data on your system, need it urgently, and can’t get past the BIOS. Remember that you can always remove the hard drive with the data and access it from another system. The BIOS password (typically) only pertains to the motherboard. There are some manufacturers, IBM and Dell included, who are encrypting the HDD to the motherboard. If this is the case, try contacting the manufacturer for a password to unlock the HDD.

    This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I’ll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

    A. By Using the Motherboard Jumper:

    In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

    Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don’t have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

    When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

    Make sure to turn the PC off before opening the cabinet and resetting the jumper.

    B. By Using Software:

    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

            Have you tried contacting Toshiba? Usually they have a master key if the following master key doesn’t work. Another method is to remove the laptop battery and the internal tiny battery. This will reset the Bios and remove the password, but it might damage the laptop or void the warranty.

      Have you tried removing the laptop battery? the tiny battery inside the laptop? removing the round tiny battery for a few minutes will reset your BIOS with no password. Remember, your warranty voids if you open your laptop. And if you have important data, make sure the person that handles your laptop perform the task in front of you.

    If you have a recent Dell laptop, the only cure is to find someone to install a new BIOS chip, or have Dell replace the motherboard if it is under warranty. Just went through this with a client who has a 2 year old +- Dell Inspiron 3542, and that is the Gospel from Dell Tech support. No jumpers on the mobo, no magical master password from Dell. Dell removed the jumper from their laptops in 2004, but the encryption has gotten stronger and stronger to the point where it would take the NSA to crack it, because even Dell has a very low success rate. We never got to the point of discussing if those fixes would help if the PW was also set on the hard drive, but I suspect that in that case, you are totally SOL. If you do set either of those passwords, for your own sake do regular backups of your important files to an external drive.
