In older computers, the CMOS battery was responsible for this, but in newer computers, the BIOS and settings are stored in nonvolatile storage like flash memory or EEPROM. If you decide to change the boot order, disable a USB device or even set a BIOS password, it would all be pointless if the settings disappeared when you turned off your computer and unplugged it. This little battery is used to keep the time and store BIOS settings even when the computer does not have power. MostВ computers have a small battery installed on the motherboard called a CMOS battery. I was pretty shocked how easily this worked, so itвЂ™s the first thing you should try before cracking open your computer.

All you have to do is turn off the computer and turn it back on and youвЂ™ll be able to enter the BIOS password again without any issue. Without getting too technical, the reason it worked is because the password generated by the website and my passwordВ generate the same checksum.ДЄlso, donвЂ™t worry about the system disabled message because itвЂ™s just a scare tactic. I tried the Generic Phoenix password on my laptop and it worked! What is amazing is that the password I had put on the BIOS wasnвЂ™t even the same as the one listed on the website, but it still worked.

For example, I have an Acer laptop at home and I went ahead and set a BIOS password and then entered the incorrect password three times.ДЄfter the third time, I got a message saying System Disabled, but I also got a number displayed right below that message.ДЄll you have to do now is go to a website called and simply type in that number! It will give you back a set of passwords for different BIOS brands that match that checksum.

So most BIOS manufacturers have a fail-safe that will show what is called a checksum of the password once you enter the incorrect password more than 3 times.
