    How to Reset a BIOS Password.


    Desktop Machines.

    In desktop machines its very simple.
    Just remove the BIOS Battery from the motherboard and place it back after 1mint.

    Laptop Machines.

    It is some what difficult in laptop machines. Because it is not an eassy job to remove BIOS battery from the mother board. So i'm just explaining some most commen methods.
    1. Using a Backdoor BIOS Password

    The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

    AMI Backdoor BIOS Passwords Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
    Award Backdoor BIOS Passwords One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, 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 Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
    Backdoor BIOS Passwords from Other Manufacturers Reported BIOS backdoor passwords for other manufacturers include:
    Manufacturer BIOS Password VOBIS & IBM merlin Dell Dell Biostar Biostar Compaq Compaq Enox xo11nE Epox central Freetech Posterie IWill iwill Jetway spooml Packard Bell bell9 QDI QDI Siemens SKY_FOX SOYO SY_MB TMC BIGO Toshiba Toshiba 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 real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

    2. Resetting the BIOS Password using Software :

    !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:
    • 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
    3. Resetting the BIOS Password using Hardware :

    If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
    On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
    If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
    Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

    4. Vendor Specific Solutions for Resetting the BIOS Password :
    Resetting a Dell BIOS Password For information on how to recover a Dell BIOS password, please refer to How do I reset Dell BIOS password?
    Resetting a Toshiba BIOS Password KeyDisk will reset the BIOS password on Toshiba laptops.

    Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.
    Resetting an IBM ThinkPad BIOS Password For information on how to recover an IBM Thinkpad BIOS password, please refer to How do I reset an IBM ThinkPad BIOS password?
    Resetting an IBM Aptiva BIOS Password Some IBM Aptiva's can be convinced to bypass the startup BIOS password if you press both mouse buttons repeatedly while booting the system.
    Resetting an Acer BIOS Password For information on how to recover an Acer BIOS password, please refer to How do I reset an Acer 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."

    Resetting the BIOS Password using Software

    Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.

    You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.

    !BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

    Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

    RTC's which require external batteries include:

    * Dallas Semiconductor DS12885S
    * TI benchmarq bq3258S
    * Motorola MC146818AP
    * Hitachi HD146818AP
    * Samsung KS82C6818A

    Most RTC chips with integrated batteries can be reset to clear the BIOS password by shorting two pins together for a few seconds.

    You will see more than one option for some chips due to testing by various people in the field. Remember to remove power from the system before shorting these pins.

    RTC Chip Pins
    Dallas DS1287A
    TI benchmarq bp3287AMT 3 (N.C.) and 21 (NC/RCL)
    Chips & Technologies P82C206 12 (GND) and 32 (5V)
    -or-

    OPTi F82C206 3 and 26
    Dallas Semiconductor DS12887A 3 (N.C.) and 21 (RCLR)

    You should be able to discover how to reset the BIOS password stored in most RTC (Real Time Clock) chips by reading the manufacturers data sheet for that RTC. Some RTC's, like the Dallas DS1287 and TI benchmarq bq3287mt cannot be cleared. The solution to resetting the BIOS password on systems with those RTC's is to purchase a replacement RTC chip. How inconvenient!
