Removing the CMOS battery will cause the system to loose all CMOS settings including the password. To do this locate and remove the CMOS battery on the motherboard for five minutes. After this has been done put the battery back into the computer and turn it back on.

Reset cmos

Modern computers use a BIOS not CMOS. Regardless of what we call it, if you can enter the BIOS by pressing the F2 key (could be a different key, check manual) there should be a choice to restore defaults. If you cannot get into the BIOS then usually just removing the small silver coin battery from the motherboard for 10-seconds and reinstalling it will reset the BIOS and your clock (which is how you will know it has been reset.)

If you are trying to reset the system because of a lost BIOS/Low Level password, take note that these passwords are often stored in a special microchip on the motherboard and often require a new logic board be installed to resolve the issue. Manufacturers protect the BIOS passwords to help protect user information and to reduce the value of stolen computers.

System disable

The BIOS password can be reset by lifting the (usually white) plastic jumper on the logic board. It will be on two pins and should be the only jumper on the board itself. I can't be certain where it is on your board, as the boards are always so different.

I set a bios password and now i forgot it (like most people would). it asks for a password before it loads windows. i would like to get pass the password and into the windows booting system.

Welcome to Fixya

There is no way for you to decipher the motherboard BIOS password. You may try to take out the CMOS battery of the motherboard to reset it the board but it is not 100% guarantee that the password will be wiped out.

If taking out the battery will not fix the problem then you need to send in the computer to lenovo and have them reset the motherboard. They have the right tool reset the board.

Thank you for using Fixya!

I want to break my bios password.

if you are using a desktop computer you can reset *********** board settings by removing the battery or by connecting the jumper setting but to do this you need the manual of the mother board. you need to find the exact place where to connect the jumper. if you are using the laptop there is no way you can reset the motherboard of the laptop. some people use a program just to reset the bios settings but for it is quite dangerous. because it might damage the bios program in the mother board.

Forgotten password ASUS P4P800-VM

There is a blue jumper located just below the lithium battery on the motherboard. You need to remove the jumper and move it to the two pins on the right for about 10 seconds to clear the CMOS then move the jumper back to where you found it. That should clear out the password. It will also change all the BIOS settings back to factory so adjustments to the BIOS may need to be made after reset.
