Most personal computers don’t have BIOS passwords because the feature has to be manually enabled by someone. However, a lot of corporate machines have BIOS passwords set for security reasons and if you’re reading this post, you’ve probably realized it’s not that easy to break a BIOS password.

The common methods to reset BIOS password include: Generating a BIOS. Use a master password generated from a hash code to reset the master BIOS password. The BIOS password for their respective computer try the hashcode generator. For information on how to recover an Acer BIOS password, please refer to.

Whether you can load the operating system or not depends on how many security settings have been enabled. On most modern BIOS systems, you can set a supervisor password, which simply restricts access to the BIOS utility itself, but allows Windows to load. A second option usually called Boot Up Password or something similar has to be enabled in order for you to see a message before the operating system loads.

It’s also worth noting that you may have to open up your computer in order to try and bypass a BIOS password and if you have a desktop, it’s usually a lot easier. Not only is it easier to open a desktop, finding the component that needs to be taken out is much easier also.

In this article, I’ll mention all the different ways you can try to circumvent a BIOS password and hopefully it’ll work. Method 1 – BIOS Password Backdoor The easiest way to get past a BIOS password is to use a backdoor password. If that elicits any kind of Edward Snowden thoughts, you’re on the right track. Fortunately and unfortunately, BIOS passwords are not very well protected and that is done purposely so that technicians and others can help people get into their computers. It’s good because this will probably help you get access to your computer, but it’s bad because anyone who thinks a BIOS password has made their computer super secure is gravely wrong.

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. 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. After the third time, I got a message saying System Disabled, but I also got a number displayed right below that message. All 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.

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 wasn’t even the same as the one listed on the website, but it still worked. Without getting too technical, the reason it worked is because the password generated by the website and my password generate the same checksum. Also, don’t worry about the system disabled message because it’s just a scare tactic. All you have to do is turn off the computer and turn it back on and you’ll be able to enter the BIOS password again without any issue. I was pretty shocked how easily this worked, so it’s the first thing you should try before cracking open your computer. Method 2 – CMOS Battery Most computers have a small battery installed on the motherboard called a CMOS battery.

This little battery is used to keep the time and store BIOS settings even when the computer does not have power. 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. 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. This type of storage doesn’t require power and therefore doesn’t have any limitations like the CMOS battery. Mostly the CMOS is used for maintaining the real-time clock for the computer.

Basically, the chances of this working on a modern computer are pretty low, but it’s worth a shot because the other options are more complicated. You’ll have to open your desktop case or laptop panels and find the circular silver battery.
