Our laptop security chips are here. Our hard disk unlocking service is here.


If your computer won’t boot without a password or you need a password to enter the computer set-up or change the settings, then you have a BIOS password set. BIOS is an acronym for basic input/output system. The BIOS is the basic instruction set that “teaches” the computer how to access disk drives, keyboard, display, etc.  The BIOS is typically placed on a ROM chip in the computer, hence the term ROM BIOS. The ROM BIOS allows the computer to boot itself. The BIOS is required to boot the computer.  Thus, if the BIOS is password protected, the computer will not boot (or you will not be able to enter or change the BIOS settings.)


There are a number of different BIOS types, but most PC’s have a BIOS supplied by one of four companies: American Megatrends, Inc. (AMI), Award, Inc., Phoenix Technologies, Inc. or IBM. Award Software became part of Phoenix Technologies in September 1998 – their main website is the Phoenix Technologies site.


Additional security features have been built into laptop computers. These usually include a hard disk password and a more secure BIOS system. For more information about laptop BIOS passwords, review our security chips page here.


BIOS passwords can be set to require the password before booting the computer or to require the password only to enter and/or change the BIOS set-up (which might be required in order to upgrade the computer.)




If you can boot the system, BIOS password recovery is usually easy. The first thing you will want to do is to use a BIOS password cracker to recover the actual password. There are a large number of BIOS password crackers available from a variety of sources. Some BIOS crackers only work with certain BIOS versions and some work better than others. You may have to try a number of crackers before you find one that works.


Some BIOS’ have pre-installed backdoor passwords that enable access to the system if you have lost or forgotten your password. Attempting to regain access to the computer by using one of the following backdoor passwords should be your first step if you have lost or forgotten your BIOS password and cannot boot your computer. If you are able to regain access to your system by using a backdoor password, you can then use a password cracker to reveal the stored password or enter the BIOS setup to change the password. These backdoors are more likely to work on older desktop systems. We are not aware of any name brand laptops or notebooks that have backdoor BIOS passwords.


At boot-up note the BIOS provider (Award, AMI, Phoenix, IBM, etc.)


For Award BIOS’ try these backdoor passwords:



For AMI BIOS’ try these backdoor passwords:



For PHOENIX BIOS’ try this backdoor password:



These backdoor passwords have been provided to you free of charge. If you have attempted to use these backdoor passwords on a system (even just as a test), we would appreciate knowing whether these backdoors have worked for you. Please email us at pwcrack@pwcrack.com with the BIOS ID number, whether or not the backdoor worked, and which backdoor worked. This information will help us assist others in the future. The AMI or Award BIOS ID appears at the bottom of the screen after power on.


In BIOS’ with a release date of December 19, 1996 or later, Award required OEM customers to configure their own security default BIOS passwords using the Award MODBIN.EXE utility, version 4.50.60. If you are aware of any other backdoor BIOS passwords please let us know at pwcrack@pwcrack.com.


If you are unable to recover the password with a BIOS password cracker or a backdoor there may still be options available. However, we recommend that the additional work only be attempted by a qualified technician.




If you cannot boot the system without the BIOS password, then using a BIOS password cracker is not going to work (since you cannot run the program.) You should first attempt to gain access to the system by using the backdoor passwords listed above. For many desktop type PC’s, BIOS passwords can be reset by removing the CMOS battery for a number of hours. However, care should be taken when attempting recovery in this way since this method may also clear any BIOS customizations and render PC components inoperable.




Most laptop manufacturers have provided additional safeguards for their computers. We are not aware of any simple BIOS recovery program that works on laptops, nor are we aware of any simple backdoor passwords for these machines. BIOS passwords in most laptops are stored in a special chip on the motherboard and the only way to bypass this password is to replace this laptop security chip. Laptop BIOS passwords cannot be bypassed or reset by removing or shorting the CMOS battery. Further, doing this may cause other system errors and complicate the recovery or your system.


We offer a full-range of replacement laptop security chips. These chips will allow you to bypass the laptop BIOS password. Note that these chips will require soldering on the system board (a hot air soldering kit is also available.) Since these chips store the laptop BIOS passwords, replacing the laptop security chip will remove the BIOS password. However, if a hard disk lock password has been set, it will remain. Passwords can be recovered from the original chip removed from the system board using our Password Recovery Service (PRS) for an additional fee. Since the BIOS password and hard disk lock passwords are usually the same, recovering the BIOS password from the old chip may allow you to access the hard disk. However, this is not guaranteed, since these passwords can be set independently. All replacement chips include detailed instructions. Password Crackers, Inc. cannot take any responsibility for damage to system boards, computers or data. More information about our security chips and our chip password recovery service are available on our security chips page.


One exception to the above chip information is the Toshiba Security Access Key. The Toshiba Key allows for the immediate bypass of the BIOS password from most Toshiba models without soldering. More information on the Toshiba Key is available on our Toshiba security chips page.




Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure (since the disk will not allow and reads or writes to the disk, it cannot be reformatted.) Usually, the BIOS password and hard disk lock passwords are set the same by a user and we can recover the BIOS password directly from the laptop security chip (after it is removed from the system board.) However, it is possible that the BIOS password and hard disk lock passwords may be set different. In this case the BIOS password will not unlock the hard disk. You can test to determine if your hard disk is locked by attempting to access it in another laptop. Password Crackers, Inc. offers a service that can unlock most models of laptop hard disks. Detail are available on our hard disk page.
