How to Bypass BIOS Passwords

BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS v Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:
Using a manufacturers backdoor password to access the BIOS
Use password cracking software
Reset the CMOS using the jumpers or solder beads.
Removing the CMOS battery for at least 10 minutes
Overloading the keyboard buffer
Using a professional service
Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.
----------------------------------------------------------------------------------------------------------- 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. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
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

after boot, appears ENTER PRIMARY MASTER HDD USER Password i need the password @ solution to boot up my lappy... thanks


How Do I Change the Primary Master HDD User Password?

Prior to loading an operating system, your computer will first execute the BIOS program. The BIOS has an extra password feature, called the hard disk drive (HDD) user password, that can't be bypassed and provides a layer of defense to keep your data secure. To change an existing HDD user password you will have to load the BIOS menu, which is only accessible during the computer's operating system reboot procedure.

Instructions

1. Close any windows that are currently open on your computer. Eject any discs inserted into the optical drive and disconnect any peripheral USB devices.

2. Open the "Start" menu and select "Shut Down." Turn on your computer once the operating system finishes shutting down.

3. Press the key your computer uses to load the BIOS menu. For example, with Dell computers tap "F2" when the "Press F2 for Setup" option appears. Press the "Access IBM" key on IBM laptops or "F10" on HP desktops.

4. Navigate to the BIOS tab that contains the HDD password option, which will usually be the "Security" tab. Some computer manufactures instead include the password option in the "Advanced" tab.

5. Scroll down to the option labeled either "User Password" or "BIOS lock" and hit "Enter." Type the current master HDD user password when the prompt appears and press "Enter."

6. Input a new HDD user password and hit "Enter" again. Navigate to the BIOS tab labeled "Exit" or something similar.

7. Move over to the "Save and Exit" entry and press "Enter." Select "Yes" and tap "Enter."
