Find out your bios password

The bios can be protected with a password to prevent third parties from accessing and modifying its settings. You have to enter the password to access it, and if you can't provide the correct one the access gets denied. This can be useful if you want to prevent users from booting from CDs or USB devices among other things.

The following method describes a way to recover the password if you forgot it or bought a used computer with a set bios password, or if you are working in a company and need to get into the BIOS but the records of the password are no longer available.

CmosPwd is a free program that displays information about the system's bios once it is executed. You do need to create a bootable disk to execute the program in dos mode. To create a bootable disk in Windows right-click the disk drive and select format from the list of options. It is important that you enable the option Create an MS-DOS startup disk.

Once the disk is created copy the contents from the dos folder of cmospwd to the disk and restart the computer. You will have to remove all hard drives from the system if you do not automatically boot from disk drive. Type cmospwd.exe in the command line and the password should appear. Ignore the information about the other bios manufacturers and take a look at the one your computer is using.

Please note that this message only works if the computer is configured to boot from floppy disk and if a floppy is connected to it. If the boot option is limited to the hard drive for instance, you can't use alternative boot media for this operation.

Another possible method is be to start the computer in safe mode with command prompt which could work as well. You still need to access the files somewhere so make sure that the hard drive is accessible.

Most computers do not have a floppy disk drive anymore. You can alternatively check out a list of BIOS password backdoors here.

You can alternatively try and remove the CMOS battery of the bios which does take care of the bios password but also of all settings. The last method will work a 100% of the times but is also a dead giveaway that someone modified the computer's password.

      Look for a jumper on your MB that resets the system BIOS. If there is no jumper, you can disconnect the CMOS battery for several minutes, but this method won’t work on all systems.

      Have you tried to remove the CMOS battery?

      why not just dis connect all power (battery pack for lapytop), remove the cmos battery for 5 minutes then replace it, reconnect and it is done…
      This does require digging into the inside of your machine. please referr to your specific manufacturers guide for details.

      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
