Just like all our passwords we do forget one of them and sometimes the forgotten one is be your own bios password. In this case, most people sending their computer to the IT department or sent back to the manufacture’s service center to break or reset that password and I know it can be expensive because it’s also not covered in the laptop’s warranty. So, doesn’t worry about it ‘cos in this tutorial I’m gonna show you how you can easily remove or break your laptop’s BIOS or CMOS password by just using some backdoor password or removal tricks.

This tutorial is intended for experienced computer hardware engineer and if you are not one of them or maybe you’re a home user then you shouldn’t have to try it alone and you can get some assistance from an experience holder person.

So let’s start with the first one and read to the end:

#1 – Reset By Backdoor Password

There are some of the backdoor passwords what your laptop’s bios manufacturer company makes to open the bios menu in the case of customer forgets their own created password. Here are some passwords according to the Bios Company.

  1. Award BIOS backdoor passwords:
AWARD_SW KDD award j256
CONCAT Djonet AWKWARD 01322222
TTPTHA ALFAROME Awkward 589589
aPAf ALLy 01322222 589721

2. Dell Dell
3. Biostar Biostar
4. Compaq Compaq
5. IWill iwill
6. Jetway spooml

#2 – Resting By Password Cracking Software

We can also remove the bios password by using the cracking software’s like “Hirens BootCD 15.2”. The best part about this Hirens Boot CD is, it’s a bootable software which contains numbers of diagnostic tools and a live operating system too.

Download the Hirens boot cd and make a bootable USB Pendrive of “Hirens BootCD”. If you don’t know how to boot a Pendrive then here’s our another tutorial to show you how to do that:

Step 1 – Boot the “Hirens BootCD”

Open the boot menu of your computer by pressing F9, F10, F11, F12 whatever your motherboard support’s and Select the Usb drive or DVD-RW to Boot Up your bootable device what you’ve made recently.

Step 2 – Select The Dos Programs.

After booting the USB you will see the Hirens boot cd menu like this and now you’ll just need to select the Dos Programs.

Step 3 – Select The “Next…” On The 9th No.

Select Next and do it again and again until you’ve find the “BIOS/CMOS tools”, after that open it.

Step 4 – Select the Bios Cracker 5.0 tool in the BIOS/CMOS tools.

After selecting the “Bios Cracker 5.0 (cmospwd)” your screen got fluctuate and you’ll see some software gets to auto start and ask you some of the questions like language or something, you’ll just have to press the “Enter” key on your keyboard and that’s it.

After some of the questions you will see, the program asks you to “Press enter key to continue”. Just press the enter key again and your laptop bios password gets reset.

Restart your computer and check the password is removed or not, if the password still remains, try ours another solution listed below.

#3 – Resting By Bios Jumper And Solder Bread

You can also break the bios by shorting the CMOS jumper, which you’ll find on the motherboard of your laptop. Shorting the jumper for 20 seconds can reset your bios password. Mostly the bios jumper (solder bread) located, nearest by the ram slot or the CMOS battery.

The CMOS jumper looks like this:

Step 1 – Open your laptops back cover or ram case cover.

Step 2 – Find the jumper.

Step 3 – Short the jumper by some small piece of wire for 20 sec.

After shorting, the password has been cleared. If that works, screw back the cover and load the default setting in the bios to make it as it in the original position. If the password still remains, try another solution listed below.

#4 – Resting by C-MOS battery

All the CMOS and bios setting is saved in the bios chip which was soldered on the motherboard and the main work of CMOS battery is to give continuous power supply to the bios chip to save all the settings on it.

If you unplug or remove the battery for above 5 sec it will turn off your bios and by turning the bios off the setting will be reset.

Step 1 – Unplug all the power supply which is connected to the laptop like “Laptop’s Battery” or “Power Adaptor”.

Step 2 – Disassemble your laptop and find the CMOS battery which was attached to the laptop’s motherboard. Watch the laptop disassembly video on the internet to know where your laptop’s CMOS battery was located; sometimes it was on behind the case of ram.

Note – If you don’t know how to disassemble your laptop then watch a disassemble video of your laptop on YouTube or some other helping website.

Step 3 – After finding the battery, just disconnect it or remove the battery for 5 sec.

Step 4 – Short the CMOS battery connector by the use of some metal wire because in some case the motherboard’s manufacturers make a backup power supply to the Bios Chipset by using of some capacitor. So, that’s why we need to short them to clear the remain power supply from the motherboard.

Step 5 – Reinstall the CMOS battery and assemble back your laptop and that’s it. Now just Power ON your laptop and the bios password is gone.

Note – Sometimes this solution doesn’t work. In that case, you’ll have to flash or reinstall your bios software or maybe replacing the bios chip.
