How to clear an unknown BIOS or CMOS password

In computing, BIOS (basic input output settings) refers to the information stored regarding a computer's hardware configuration, the system date and time and any applied password. This information is known as the BIOS or CMOS settings--the BIOS is stored on a small battery-powered semiconductor chip known as the CMOS (complementary metal oxide semiconductor). Having a CMOS or BIOS password restricts unauthorized changes to the system's hardware configuration and, in some computers, may even be required for booting. A lost password may be reset by removing the CMOS battery, clearing the motherboard jumper or using a software-based password cracker.

Removing CMOS Battery
1. Shut down the laptop and unplug its power cord from the wall outlet. Remove the battery cover under the laptop and gently raise the battery from its dock. Unplug any peripheral devices with a live power source connected to the laptop, such as a modem or printer.

2. Locate and remove the CMOS battery. Refer to your user manual or visit the manufacturer's website for your laptop's architecture. Follow manufacturer recommended procedure to access and remove the CMOS battery. Depending on make and model, this procedure may be more involved for some laptops and not others. The CMOS battery is a flat circular shape and resembles a watch battery.

3. Wait 30 minutes and then put the battery back in. This will erase all information stored in BIOS. Assemble the laptop, making sure you leave no loose connections. Power up the laptop and press "F1" when you get the "CMOS cheksum error" message. Type in a new password.

Clearing CMOS Jumper
1.Turn off the laptop and access the motherboard following recommended procedures.
2.Locate the jumper in the motherboard. If you do not have your motherboard documentation, locate a single jumper near the CMOS battery. In some laptops, the jumper may also be labeled in the motherboard. Put the jumper setting to "Clear" and reassemble the laptop.
3.Turn on the computer and hit "F1" when the "CMOS checksum error" message is displayed. Navigate through the BIOS settings interface to load default settings and apply a new password.

Using Password Remover
1.Download a software-based BIOS password cracker. There are numerous free programs able to recover or delete CMOS or BIOS passwords from virtually all motherboard brands. Download the file from a trusted source and save it to the desktop.
2.Burn the installed file to a CD using image burner software. Insert the CD and access the password remover tool.
3.Note the password or use the program to set a new password.

I hope you find it very helpful. Thank you for using fixya.

If you know how to remove the CMOS battery on the motherboard of your laptop this will solve your problem. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard.
Removing the battery will reset the CMOS information/data including the password.
Of course after you have done this you have to re-enter the correct CMOS info in order for your laptop to function properly.


Good day.

To reset BIOS password, you must remove CMOS battery, not regular one. CMOS battery is located somewhere on the mainboard, so you have to open laptop.
OR
You can put out regular battery for few days, and it should reseted.
OR
You can try CmosPwd

Hello,

The BIOS password cannot be bypassed or disable. You need to know the password to reset it. If you don't know the password then you will need to physically reset it.

Here's a video on how to reset it.

WARNING:
If your not sure how to do it. Take it to the nearest computer repair center.

Go to your friend. Download and burn this cd http://www.9down.com/Hiren-s-BootCD-9-8-Keyboard-Patch-73110/
Boot your pc from it by pressing F12 and use BIOS / CMOS Tools from it.

You need to locate the Cmos battery, not the jumpers, this is not a desktop.

Locate the Cmos battery, disconnect the battery for ten seconds, and Bios will reset to factory default.

Resetting the cmos has nothing to do with the Windows OS. It only helps you if your BIOS is password protected.

...and the whole idea of a password is, that nobody else can hack into your machine that easily, right?

Anyways - there are ways to reset a password: google is your best friend in this case. And you will need access to a CD burner, since you have to boot your laptop from the downloaded "Rescue-CD".

The Password can be removed via the printer port
What you need is a password removal tool, It removes the Bios and start-up passwords.
It costs about £5.00. Easy to build but it costs more to put the kit together.
I think you were quite hard on the assistance.
People here are just trying to help. At least appreciate that!
