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

Im not able to boot from os cd the bios can see rom drive and hard drive but im not able to boot iv'e tried f12 but no joy can you help?


hi there.

If you go to the bios on start up and select cd rom drive as your primary boot and then restart. Your computer will then try to boot first from the cd rom drive and second from the hard drive. If it fails to boot from the disk then this would lead me to believe that either the disk is unreadable by the drive or that the cd rom drive itself is unable to read the disk.

My laptop wont start up, It says "system disc or non system disc error, replace and press any key.." why? :(


you have it set to boot from cd so when you startup the computer it attempts to read the cd and than boot an operating system for you either remove the disk or enter your bios menu and set your boot order to negate the cd drive

Unable to remove write protection. I did not write protect the hard drive.Reformatting is not an option.


First of all ensure that you have not changed any BIOS option like 'write protect'. You can enter bios settings by keep on pressing 'DEL' or F2 key (depends on your bios) while booting. After entering select default settings. Save, Exit and Restart. If your problem still persists, then check for jumper settings (usually provide in SCSI disks) are set to read and write.

Installed new WD HDD in dell 8400 unable to boot from CD


Make sure that the operating system cd has no smudges, dirt, dust, etc on it.

What I would do since you have two optical drives in the system. Disconnect one of the drives at first and only hook up one of the optical drives and make sure the jumper on the back is set to master.

Go into the BIOS and reset the bios defaults and have it redect the hardware in the system after this you'll get the same message so reboot into the BIOS and set the optical drive as the first boot device. Hopefully it will read the cd and you press and key to boot up off of the cd.

If this doesn't work then repeat all the steps i mentioned for the 2nd optical drive. Hopefully it will read the cd properly with this drive. Im checking to see if one or both drives have bad lasers in them.

If the 2nd drive doesn't read it then at this point disconnect the hard drive completely from the system and then turn it on and see if the optical drive can read the cd, if it does at this point then that means your new hard drive is defective cause its shorting out the secondary controller on your motherboard.

Let me know how things go and I'll help you further if you need some more help.
