Bios Password Cracking - Default BIOS Passwords List

How to Bypass BIOS Passwords

BIOS passwords can be add extra layer of security for desktop and laptop computers, and are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. BIOS passwords can also be a liability if a user forgot their passwords, or if a malicious user changes the password. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in an a typical warranty. However, there are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS password on most systems.

Backdoor Passwords

Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations.

WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords.

Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot

IBM Aptiva BIOS

Press both mouse buttons repeatedly during the boot

Using the Motherboard “Clear CMOS” Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR – CLEAR CMOS – CLR – CLRPWD – PASSWD – PASSWORD – PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.

Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.

Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don’t attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.

Note: Removing the battery to reset the CMOS will not work for all PC’s, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.

How to Access the CMOS or BIOS (Basic Input Output System of your Computer)

How to Access the CMOS or BIOS (Basic Input Output System of your Computer)

Accessing the computer’s BIOS can vary depending on the Brand and Model of your computer, as well as the type  of BIOS they use. In this article we will discuss how to access the computer’s BIOS based on the Brand, Make, Model and even Year of the Computer.

This is a popular screen commonly found while working with the Award BIOS Menu.

BIOS is the Basic Input Output System and menu-ing system used to define and interface with the various hardware components of your computer: such as Hard Drives, DVD ROMS, as well as Video, LAN and Audio Cards.

The manufacturer typically installs all of this for you but by using the BIOS we can turn these devices ON or OFF or even change their default settings completely to allow for hardware upgrades and greater compatibility.

CMOS – pronounced see-moss, is a  Complementary metal–oxide–semiconductor chip that holds information saved by the menu-ing system of the BIOS. The CMOS retains this information (normally) as longs as a standard PC battery, is charged and in place on the motherboard of the computer.

The CMOS Battery is technically referred to as the CR2032 or Three Volt Watch Battery

In some cases when the BIOS or CMOS is password protected, you should simply remove this battery to reset the chip to its default settings and thus remove the password completely or reset the password to a default manufacturer’s password as outlined by the makes and model list below.

While replacing the CMOS battery in a Desktop is really very easy; Special care should be taken before trying to remove the same type of battery in a notebook or Laptop.
