not all laptops remove the cmos will work thats very old 90s solution

the bios password is located on the main bios IC like eeeprom named winbond or MX in toshiba devices

you must remove it with hot air then flash the IC with a programmer with new bios file

is not easy as i see in the comments

Short circuit the system clock battery (preferably an old battery, not a fresh Lithium Battery to be shortcircuited ) fitted in the motherboard and then reboot your machin

I also try to find some other solutions because I also lost my BIOS password, and I think this article about how to reset or remove BIOS password will be of great help:

Try removing the CMOS/BIOS battery or see if there is a jumper on your motherboard that will reset the password.

remove the jumper on the board

As far as I know about BIOS, there is 2 forms of BIOS passwords. The forms are desktop and laptop/notebook.

Desktop BIOS passwords are easy to bypass by moving the jumpers.

Laptop BIOS passwords are way more difficult to bypass as they are stored on the EEPROM chip which is soldered to the motherboard.

If you don't know the BIOS password, you need to either talk to the guy who previously owned them or put new motherboards in them to get past the BIOS password.
