BIOS and Power on Password Removal To remove the BIOS password on computers (NOTE - This method does not work on some later model computers), remove the BIOS battery, wait 20 mins. and then re-insert the battery. The BIOS will reset to the default settings, then go to the BIOS configuration and set the date & time etc. For ThinkPad laptops, please click on this link and follow my instructions :- http://www.fixya.com/support/r4335050-remove_bios_power_password_thinkpad For Toshiba computers, please click on this link and follow my instructions :- http://www.fixya.com/support/r4350719-remove_toshiba_bios_password If these procedure do not work, then here are a couple of WEB sites that may assist you. http://repair4laptop.org/laptop_and_notebook_bios_password_reset.html Passwordportal.net http://www2.searchresultsdirect.com/parking.php4?domain=passwordportal.net®istrar=238091&keyword=find+password&eq=b3a7c686246e518765d51d1e75199f06&ac300=2

How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.
Anyway, open up the computer case using a screw driver and locate the flat, circular and metallic CMOS battery. It should look something like the picture to the right. Some computers have this part standing upright.
Once you have located it, observe how the latches are holding it. There are many different ways to remove a CMOS battery but the most common way on newer computers can be seen in the picture below.

Make sure to power down the computer, unplug the power cables and unplug any USB devices if they are powered. The computer must not be able to get power from anywhere for this to work. Take out the CMOS battery and wait 10 - 25 minutes before putting it back in. The reason for this wait is because the computer can still store power in its capacitors even though everything is unplugged. The waiting period allows enough time for them to discharge.
Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should be no more password. In some cases, if you get weird error messages during bootup now, you will need to goto "Load BIOS Defaults" in BIOS and save the changes to fix them.
If this method didn't work, try one of the methods below.
How to Bypass or Remove a BIOS Password using Software:
!BIOS is a freeware utility which is designed to be a whole BIOS and security suite. It has the ability to decrypt the passwords used in some of the most common BIOS makes such as Award, Phoenix, American Megatrends, IMB etc..
It also has the ability to brute force the password (known as "blasters"). However, this method is dangerous and can result in some unexpected and unwanted results.
Note: Because of this applications password cracking abilities, some antivirus software may report it as a virus/trojan. This is a false positive.
To start using !BIOS, reboot your computer and take note of the BIOS type and version you are running. For example, If your motherboard uses Award BIOS you should look for the text "Award Medallion BIOS 6.0? or something similar.
Download !BIOS from here and save it to your desktop. Then, open a DOS command windows by going to Start > Run and type: cmd
Once you see a black screen in front of you, type: cd desktop
You should now see something like: C:\Documents and Settings\YourUserName\Desktop>
Now type the name of the file you just downloaded, if you haven't changed the name just type in: bios320.exe

Use the down arrow and choose "Crackers" and then press the right arrow. Using the up and down arrows, select the BIOS that the motherboard is using and press Enter.
You should now see a menu asking what you want to crack, in most cases its the Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing the 1 key on your keyboard. You should now have your BIOS password.
Reboot the computer, enter the BIOS and try it out.
How to Bypass or Remove a BIOS Password using the manufacturer backdoor password:
On many computers (especially old ones), computer manufacturers build in backdoor passwords for their own technicians to use so they can access the BIOS when the hardware is being serviced. Here are some of the ones that have been reported. You may need to try quite a few passwords before you find one that works

Try this Method:

One of the most common methods to reset the BIOS password is to remove or discharge the battery on the computer's motherboard. If the power to the battery is lost or drained, the BIOS configuration will be reset to the factory state with no password. System settings made to the BIOS will also be lost.
Step 1 - Turn off the computer and ensure it has no external power (ie unplug the power cable. If it has a battery, remove it).
Step 2 - Open the computer's case or box.
Step 3 - Locate the computer's motherboard and look for the white silver button battery on the motherboard.
Step 4 - If the battery is not soldered to the motherboard, remove it carefully and wait for approximately 30 seconds.
Step 5 - Put the computer case back together and boot the computer.
Step 6 - If the "CMOS Checksum Error-Defaults Loaded" error message is displayed, the BIOS password has been reset.
In the event the CMOS battery is soldered to the computer's motherboard, you will want to seek a different method to reset the BIOS password on the computer.

Hello,
There will be a back door password , password can reset for some model in dell platform.A BIOS password is a protection measure that can be used to stop someone powering up a computer system or making changes in some of the computers most sensitive areas. Many big name computer manufacturers such as Dell and HP lock the customers out of this area because they don't want the customer changing anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when someone like a computer technician or hardware enthusiast needs to make some hardware changes to the computer, they will need to access the BIOS. Here are some methods to bypass or remove a BIOS password.

How to recover your forgotten laptop BIOS password? There are 3 methods, each method has its strength and weakness but I am going to talk about the 2 easy methods that works across the board for everyone. Here they are: Method 1 – Remove BatteryFor desktop user, open up your computer casing and look for the battery. Remove the battery for approximately 5 minutes (maybe longer, depending on the motherboard) and slot it back. By removing the battery and deprive the motherboard’s flash memory of power supply, you are essentially resetting the settings back to default when the existing data in BIOS are cleared.

This method works well for desktop, however this is not practical for laptop user unless the warranty expired long time ago. This method might or not not work, it depends on the type of motherboard.
Method 2 – Reset CMOS With SoftwarePC CMOS Cleaner is the best CMOS password reset software, it works setting the BIOS to the default state or revealing the password.
PC CMOS Cleaner is an easy-to-use tool to recover, delete, decode and display the superior passwords stored in BIOS whatever the brand is. Most types of BIOS are supported. It’s an bootable CD that runs on x86 and x86_64 computers. No need to pay expensive fees to experts. It’s a useful tool for users to get their lost BIOS password back, or clean passwords from an old computer bought from others.

• Support all x86, x86_64 Personal Computers.
• Support most BIOS, such as: AWARD, AMI, Compaq, Phoenix, Samsung, IBM, Compaq, DTK, Thinkpad, Sony, Toshiba and so on.
• Display the superior passwords of the BIOS .
• Remove BIOS password(will set the BIOS to default status, need reset date).
• Set the BIOS to default state
