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. Thankfully, it’s easy to spot because of its size and shape.
Make sure you turn off your computer completely, disconnect all cables and unplug the power also before doing this. Use something like a butter knife or flat head screwdriver to pop the battery out. You’ll want to wait at least 30 minutes before putting the battery back in and connecting everything back up.
Unfortunately, on some laptops and newer desktops, you may not even see the CMOS battery anymore. In that case, move on to the next method.
Method 3 – Change Jumper Settings
The third option will probably be the best chance you have of getting rid of the BIOS password on modern desktops and laptops if the first method didn’t work. If you have a laptop, you may have to call a technician because you’ll need full access to the motherboard, which means you’ll have to probably take the entire thing apart.
When you have access to the motherboard, you need to look for a specific jumper. A jumper is basically a number of pins sticking out of the motherboard with a small piece of plastic covering some of the pins. When you move that piece of plastic to cover a different set of pins, it changes the settings on the motherboard.
On most motherboards, even the new ones, you should see a jumper with a label next to it to clear the CMOS or clear the password. Now the label can be any of the following: CLR_CMOS, CLEAR CMOS, CLEAR, CLEAR RTC, JCMOS1, PWD, PSWD, PASSWORD, PASSWD, CLEARPWD, and CLR.
There are many jumpers on a motherboard, so you’ll need to search around to find the right one. The best place to look is around the edges of the motherboard first. If not there, look close to the CMOS battery itself. Usually, the jumper will consist of three pins with two pins covered. You’ll need to simply remove the jumper and cover the opposite two pins.
For example, if pins 1 and 2 are covered, you will need to remove it and cover pins 2 and 3. If there are only two pins for the jumper, just remove the cover completely. On a laptop, you may not see jumpers, but dip switches instead. All you have to do here is move the switch up or down.
Once you have changed the jumper setting, go ahead and turn on the computer, check that the password is gone and then turn it off again. You can then put the jumper back into its original position.
Method 4 – Default BIOS Passwords
If nothing else has worked so far, you can always try to use some generic or default passwords set by manufacturers. Instead of listing them all here, check out this page that has a list of all the default passwords.
If you’re lucky and the password is only protecting the BIOS utility and isn’t required to start Windows, you can try a third-party program that will try to decrypt the password.
The software works with all the major brands like Phoenix, IMB, ACER, AMI BIOS, Compaq, Toshiba, etc.
At this point, your only option is to use a professional service to break the BIOS password. They have special tools that they can use to actually remove the BIOS chip from the motherboard and flash it with a new BIOS, thereby removing the password, etc. It’ll probably cost you anywhere from $100 to $500 depending on the firm. Enjoy!
