    How to Reset BIOS Password?

    There are two passwords in BIOS. One is start up password, the other isBIOS setting password. If you have forgotten the start up password thatmeans you cannot open computer at all. Then the first method is theonly thing you can do. Other methods can use to clear setting password.
    ==①:Motherboard Battery Discharge==
    The common way toreset start up password is discharge Motherboard Battery. Most of thecurrent motherboard BIOS is using the button batteries to provideelectric power.That means if there is no electricity, the informationit contains will be lost. When it’s on power again, BIOS will set backto its original state, of course, there will be no BIOS passwords. Butyou will lose your setting at the same time.
    What we need to dois to power off computer, open the computer box, and then unplug thepower plug of the computer to make sure that it is no electricity atall. Then locate the white silver button battery on the motherboard.Remove the battery carefully. Perhaps 30 seconds later, put back thebattery.
    After put back the computer box then power on, thesystem will prompt “CMOS Checksum Error-Defaults Loaded”. That meansCMOS errors detected during inspections, had been included in thesystem default, BIOS password cracking success!
    On somemotherboards, the battery is soldered to the motherboard, making itdifficult to remove. If this is the case, you have another alternative.Somewhere on the motherboard you should find a jumper that will clearthe BIOS password. If you have the motherboard documentation, you willknow where that jumper is. If not, the jumper may be labeled on themotherboard. If you are not fortunate enough for either of these to bethe case, you may be able to guess which jumper is the correct jumper.This jumper is usually standing alone near the battery. If you cannotlocate this jumper, you might short both of the points where thebattery connects to the motherboard.
    ==② : Backdoor BIOS Password==
    Eachmotherboard manufacturer has set a backdoor password in order tofacilitate the provision of technical support. The backdoor password isa BIOS password that works, no matter what the user sets the BIOSpassword to. These passwords are typically used for testing andmaintenance. Manufacturers typically change the backdoor BIOS passwordsfrom time to time.
    AMI Backdoor BIOS Passwords
    Reported AMIbackdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW,BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
    Award Backdoor BIOS Passwords
    Onereported Award backdoor BIOS password is eight spaces. Other reportedAward backdoor BIOS passwords include 01322222, 589589, 589721, 595595,598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARDSW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT,CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332,J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz,TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
    Phoenix Backdoor BIOS Passwords
    ReportedPhoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, andPHOENIX. Backdoor BIOS Passwords from Other Manufacturers Reported BIOSbackdoor passwords for other manufacturers include:
    ManufacturerBIOS Password
    VOBIS&IBM merlin
    Dell Dell
    Biostar Biostar
    Compaq Compaq
    Epox central
    Freetech PosterieI
    Will iwill
    Jetway spooml
    Packard Bell bell9
    Siemens SKY_FOX
    Remember that what you see listed may not be the actual backdoor BIOS password,this BIOS password may simply have the same checksum as the realbackdoor BIOS password. For Award BIOS, this checksum is stored atF000:EC60.
    ==③: Software Crack==
    There are a lotsoftwares to test systems or start up password, but they need to run onWindows. So it is only used to reset BIOS setting password.
    !BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
    CmosPwd will recover the BIOS password for the following BIOS versions:
    •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
    •Zenith AMI
    Ifall else fails, you might be going to lose some money for technician.But they will use these same methods, try hard by yourself.

    How can i have the password bios of laptop dell E6420

    f you are running Dell servers, it is recommended to enable BIOS password. This is will prevent accidental changes done to Dell BIOS settings by others who get physical access to the server.

    You can setup two different types of passwords in Dell BIOS:

    System Password: This will be prompted before the system can boot up, and load the operating system.
    Setup password: The system will prompt for this password only when you are trying to access the BIOS settings.

    Depending on your situation, it might be a good idea to enable both the system and setup password at the BIOS level. I recommend that you at least enable BIOS password.
    Press F2 for System Setup

    When the Dell server is booting up, press F2 to start system setup, from where you can change Dell BIOS settings.

    BIOS System Security

    From the Dell BIOS main menu, scroll down to "System Security" and press enter.

    Password Not Enabled

    From here, you can see that both the System and Setup password is not enabled by default.

    Enable System Password (and Setup Password)

    Scroll to "System Password" and press enter, which will prompt you to enter the password that you like to set for the system. Please understand that if you set this password, you have to enter this password everytime you start the system. Do the same thing for Setup Password.

    Don't forget this bios password. If you forget, then you have go through the painful process of resetting the Dell BIOS password.
    Password is Enabled

    Once you've enabled both the password, from the "System Security" menu, you'll see that that both system and setup password is enabled as shown below.

    password is set

    System Password Prompt (During Startup)

    From now-onwards, anytime you start the system, it will not load the operating system, unless you specify the system password as shown below.


    Setup Password Prompt (To Access BIOS)

    If you press F2, to get to the BIOS, it will prompt for the setup password as shown below. If you don't enter a valid password here, you cannot access the Dell BIOS settings anymore.

    Bios password

    I.m assuming you want to know what the BIOS password is? The BIOS password is established by the consumer after purchase. It is not set by the manufacturer for obvious reasons. If you have set a BIOS password and have forgotten it, the only recourse you have is to go into the case, find the BIOS reset jumper, position it to the reset position, wait a few seconds, then replace it back to normal. This will clear the BIOS password, but will also reset the BIOS to its default factory settings. You will need to make any modifications that are desired after rebooting the machine. There is no way to hack the password once it is set, unless you're a real good guesser.

    Laptop SONY VAIO VPCEB32FM: how to remove BIOS password

    The BIOS password is probably the Power On Password.
    This method may not work. Remove the BIOS battery for 20 mins until the charge in the BIOS is depleted. Insert the BIOS battery go into the BIOS setting and set the Date and Time etc.
    If this does nor work then the BIOS password is stored on an EEPROM chip and removing the BIOS battery won't work and there is probable no backdoor passwords.
    The Sony support maybe able to offer a solution, check the support WEB site..

    How can I by pass Bios Password for Acer brand?

    BIOS passwords are used to add some extra security to computers. You can either set a password to prevent access to BIOS settings or to prevent PC from booting.
    But sometimes this extra security might become a pain when you forget the BIOS password or someone changes your system BIOS password intentionally.
    But there is no need to worry. There are many known ways to reset / remove / bypass the password:
    • By removing CMOS battery
    • By using motherboard jumper
    • By using MS DOS command
    • By using software
    • By using Backdoor BIOS password

    How do i reset the bios password for my lenovo a310?

    User passwords:
    Power on
    BIOS execution can be controlled by a Power On Password. This password is set in the BIOS Configuration screen, accessed by pressing the F1 key after pressing the power on switch to turn on the PC. If the person at the keyboard does not know the Power On Password, then BIOS execution halts.

    Hard drive
    The hard drive is controlled by the Hard Drive Password. After the Power On Password is entered, the person at the keyboard must be able to enter the Hard Drive Password, otherwise the disk drive will not spin up for use. Like the Power On Password, the Hard Drive Password is set in the BIOS configuration screen.

    Administrative passwords:
    Each of the two user passwords can be controlled by a Master or administrative password. If the administrative password is not set, then anyone who knows the user password can change it in the BIOS configuration screen. If the administration password is set, then it is impossible to reset the user password unless you know the administrative password. The Supervisor Password is the administrative password for the Power On Password. The Master Hard Drive Password controls the Hard Drive Password.

    Password Recovery is a feature of Client Security Solution 6.0. This makes it possible for an end user to recover from the problem of "I forgot my Power On Password or Hard Drive Password."
