Re: bios password

Usually you can reset the password by taking out the battery and removing the AC adapter, then either pulling out the small watch sized battery on the motherboard and leave it off for a few minutes or move a jumper on the motherboard to reset the bios. If that isn't possible or doesn't work there is a list of backdoor passwords available here.

    Problem: You do not have access to change the settings in BIOS? . Have bought a...

    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

    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)

    •IBM (PS/2, Activa, Thinkpad)
    •Packard Bell

    •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 do i unlock the forgotten bios password

    Try this:
    1. As the computer is booting press F1, F2, or Del to enter CMOS setup.
    2. In CMOS setup when prompted for a password, guess three times until you're giving the code. If after entering the wrong password three times the computer is displaying a 5 to 8 code, as shown in the picture, continue to the next step.
    3. Write down the code and visit Dogbert's BIOS Password Backdoors scripts page to download Python and the free Python scripts to clear many of these types of passwords.

    Compaq 6735b forgotten Bios password -
    this is an anti-theft thing. You are meant to contact Compaq, provide proof of ownership, a receipt etc, and they will happily provide you with an Unlock key, for a fee. They are almost impossible to Crack, as they are kept in NV RAM,and there is NO way to access it, remove it or anything other than the Unlock key. The links above may be of some help, especially on older PC's the modern ones are uncrackable by mere mortals, without that magic key.

    Locked out and I forget the password!

    If you can reach the motherboard you will find a round button cell. remove it for a few minutes and replace it again. the password would have been undone. Do not use passwords as one tends to forget them sooner or later. Or have one, if you must, that you can remember easily.
