The Basic Input Output system, commonly referred to as BIOS, is an additional layer of security used prior to booting the device. If you're wondering what the BIOS is, it's a program used by the computer's microprocessor. The BIOS password is stored in the Complementary Metal Oxide Semiconductor (CMOS). When the computer is off, some computers usually store and store memory in a small battery on the motherboard. The BIOS is a security feature that prevents unauthorized access to the computer.
However, the disadvantage is that if a user forgets their BIOS password or does not know it, the computer will not start. There could be another case, in which the enterprise company sells the computer without sharing the BIOS password. In this case, it is important to reset or remove the BIOS password. So let's start, shall we?
How to reset / remove the BIOS password?
If you have already seen something like the screen shot below and you do not know the correct key for the hole, that is the password, it's time to change it or to delete it. There are 6 ways to do it, so go ahead and find a method that's right for you!
1. Removing the CMOS battery
This is a method that can be adopted to reset the password of the bios. Follow the steps below to do the same thing:
- Locate the CMOS battery on the motherboard as shown in the image below.
- Remove it for at least 15 minutes and put it back inside.
- Start the computer.
- Reset all settings.
- If this does not work, remove the battery for at least an hour and repeat the steps.
2. Using the jumper on the motherboard
One way to reset the CMOS settings is to change the location of the motherboard jumper, often referred to as a password jumper or DIP switch. The jumper on the motherboard is labeled with CLR, CLRPWD, CLEAR, CLEAR CMOS, PASSWORD, PASSWD, PSWD, or PWD.
There is no fixed location of the rider and it varies from one brand to the other. To locate the jumper, carefully read the manual of the motherboard.
Still can not find the jumper on the motherboard?
The following list shows the general locations of the jumpers. As mentioned, these vary from one brand to the other. It is important that you change the correct password jumper, so read the supplied manual or download it from the manufacturer's website.
- Edge of the motherboard.
- Adjacent to the CMOS battery.
- Adjacent to the CPU.
- Background of the laptop.
Let's take a look at the steps to reset the BIOS password:
- Turn off the PC.
- Locate the password jumper.
- Observe that this jumper contains 3 pins, that is to say center, left and right.
- Note the pins that the jumper joins. It connects the center pin to the left or right pin.
- Remove the jumper and connect the center pin to the opposite pin. This means that if the center pin was previously connected to the left pin, remove it and connect it to the right pin.
- Wait a few seconds.
- Remove it and place the jumper as before.
3. Change the BIOS password with the MS-DOS command
This option is appropriate if you have access to the computer when it starts. It uses MS-DOS commands to reset the CMOS settings. These are the steps that must be followed:
- Open the command prompt. You will find it in the Programs menu.
- Type the following commands line by line:
debug
o 70 2E
o 71 FF
to leave
Now you only need to restart your computer and the CMOS will be reset with the BIOS password.
4. Reset the BIOS password with the help of third-party software
Many third-party software helps reset CMOS settings and BIOS passwords. Those available are:
- cmospwd– This app is used to decrypt the password. In addition, it can be used to restore or save CMOS settings.
- KillCMOS- This changes the CMOS checksums and values ​​so that the CMOS is restored to the factory settings.
5. Using the Backdoor BIOS password
This can be understood as a master password or simply a set of generic passwords. These may not be valid in all cases, but if you come so far, it's worth it, right? Here is a list of some of these passwords for some manufacturers:
AMI BIOS passwords
- AM I
- FRIEND? SW
- AMI_SW
- AM I
- AAAMMMIII
- PASSWORD
- BIOS
- LKWPETER
- Condo
- Oder
- HEWITT RAND
- MID
BIOS PHOENIX passwords
- CMOS
- BIOS
- PHOENIX
- phoenix
AWARD BIOS Passwords
- EMBARRASSING
- embarrassing
- ALLY
- ally
- ally
- Ally
- PINT
- pint
- LKWPETER
- Lkwpeter
- 589589
- 598598
- 589721
- 595595
- 01322222
- ALFAROME
- CONDO
- Condo
- CONCAT
- price
- _price
- AW AWARD
- AWARD_SW
- PRICE? SW
- SW PRIZE
It is important to note that all these passwords are case-sensitive and that passwords are frequently changed by the manufacturer.
6. Contact the manufacturer
Technically, you might consider this a cheating, but if none of the steps suited you, the last option would be to contact the manufacturer and immediately solve the problem with the help of qualified people. You can contact the manufacturer of the computer or the motherboard manufacturer.
Without knowing the password of the BIOS, it can be a major problem because one could not start the computer. With these 6 methods, you are sure to find a method that solves the problem for you and resets or successfully removes your BIOS password!
