Have you forgotten your Laptop's BIOS Password?

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Why do I keep getting a pop up asking for my password over and over again on a black screen?


If this occurs on a Window-based PC prior to seeing the Windows Start screen, it most likely means that someone has entered a System Password into the CMOS/BIOS that requires entry before the system will boot. If your CMOS/BIOS was not password-protected anyone who had access to the machine would be able to enter the CMOS and set up such a password, effectively locking you out. Of course, it they did not put a password on the CMOS itself, you may be able to enter the CMOS yourself and remove the password, as long as you do not have to know it to remove it. If you MUST know the password, you may have to do a CMOS reset to release the password. Ensure that if you do that, you know all settings in the CMOS that need to be modified from default or you may have operational issues later. If there is a CMOS password on the system as well, and you did not place it there, someone is messing with your head.

How to reset or remove BIOS password


There are four common categories of solutions to remove or reset a BIOS password and here are the details on how to go about resetting your BIOS password.<br /> <br /><b>Manufacturer Backdoor BIOS Password</b><br /><br />Most of the BIOS makers have set a backdoor password on the older computer models. That is the master password for BIOS. To reset BIOS passwords first you need to check the manufacturer of your computer's BIOS. Most computers have BIOS include AMI, IBM, Award, and Phoenix. These are the most common BIOS. You can unlock your locked BIOS using this master password. It works, no matter what the user sets the password to. Many popular computer and laptop manufacturers such as HP and DELL lock the BIOS because they want to protect their machine's most sensitive areas (those areas which have warranty) from their customers. These passwords are usually used by computer technicians for testing and repairing. <br /><br /><b>Reset the jumper that holds the password<br /></b><br />Open the computer and locate on the motherboard the BIOS password jumper. The jumper is usually jumper 1 and often labeled as PSWD, PWD, CLRPWD, CLEAR, JCMOS1, CLR, CLEAR CMOS, PASSWD, or PASSWORD. Normally you would have 3 pins and to reset the password you just need to put the jumper on the 2 and 3 pins leaving pin 1 empty. After you move the jumper, turn the computer on to clear the password, then once password removed turn it off and put the jumper back to its original position.<br /><br /><b>Removing the CMOS Battery to reset the BIOS to default</b><br /><br />Switch off your computer, and open up the case. You'll see a circular metallic silver item on motherboard. This is called CMOS Battery. Remove it carefully, and leave it out for about 2 minutes. This act will remove the CMOS memory which contains BIOS password. Set the CMOS battery back and switch on the computer. Restore the CMOS configuration as default. Your BIOS password has been cleared now. <br /><br /><b>Using third party software utility to reset BIOS password</b><br /><br />To reset BIOS you can use third party software like Kill CMOS which wipes out CMOS, or CmosPwd which is a BIOS utility. Hiren's Boot CD has a few programs including the above two that will help you to reset the password. Here is a link to Hirens Boot CD website <a href="http://www.hirensbootcd.org/">http://www.hirensbootcd.org/</a>. To download the latest version, click on the Download link on the left side and go to the last page. You will need a CD writer to put the content on a blank CD.

Lost password for acer aspire desktop


BIOS Password is stored in CMOS and retained by power provided by the CMOS (Coin-cell) Battery.
To Reset the BIOS Password, Remove the CMOS (Coin-cell) Battery from the motherboard for five minutes and restart the system. This will load the factory default settings and the password would be gone. Re-install the battery after the password is reset.

Hope it helps! Good Luck! Thanks for using Fixya!

Reset cmos password for compaq nc6400


Assuming you can get to the CMOS button cell battery, remove all power, pull the button cell out for about a minute, then put it back. The next boot-up should load right to setup, or to an error screen telling that CMOS is corrupt and to run setup.
