Thread: Remove/Recover BIOS password

PC CMOS Cleaner

There are many different ways to remove the BIOS password. You may have forgotten the password of your BIOS or you never knew it, whatever may be the case is. Sometimes it becomes necessary to access the BIOS to change system settings.
The simplest way to remove the BIOS password is to remove the CMOS battery for few seconds.A computer uses this battery to remember its settings and date & time when your computer is turned off. The CMOS battery is the reason why you always get the correct date and time whenever you restart your PC.

When you remove it from your CPU the computer will forget all the settings which includes BIOS password too. So to reset/ remove your BIOS password you just have to remove this battery once and then put it back after few seconds.
If you don’t know how to do this or if you are not familiar with computer hardware & stuff then you can try using this software PC CMOS Cleaner..





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.The download file is an iso file so first you have to burn it on a cd and then boot from that cd to recover your BIOS password.




Have Fun !!!!

But removing the battery is so much cooler :P

Nah, this is actually a pretty good tool, especially since you can recklessly damage the motherboard by removing the battery improperly (seen it happen). Just make sure you're getting a clean version.

Removing the CMOS battery wont actually work on quite a few newer laptops. Passwords are often stored in flash memory on these. So if you have a BIOS password on your laptop, set on bootup. The best bet is too not forget it in the first place!

Nice post.

In addition, many boards also have a BIOS password jumper that'll clear it for you while retaining the other settings in the BIOS. This will prevent you from having to go in and set your drives to AHCI, disable/enable any on-board devices or in general having to redo any other configuration.

Why even use a BIOS PW if it is that simple to erase it? I thought you would at least have to exchange the BIOS-chip.

My Bios has a Supervisor/BIOS Password (SVP). You'd have to read the EEPROM chip using some electronic device or use the serial port from another PC to get my SVP. Removing the battery does nothing. This PC CMOS cleaner is just as useless as it's a boot disk and my drive isn't set in my boot priority. Can't change my boot priority without the SVP.
