Solution #2 – Resting By Hacking Software –

The second best option for resting the bios password is to reset by the use of hacking software’s like “Hirens Boot CD 15.2”. We only use this software because it’s a bootable iso file who having lots of utility tools in it for diagnosing and repairing our computer.

Here’s the Software Download link >>>>>

You’ll need to make a bootable pen drive after downloading this software.

#1 – Boot the “Hirens Boot CD”

First, you’ll need to boot that software by the use of boot menu you’ll just need to press the assign keyboard key and that will open the boot menu only when the computer starts.

Normally the first boot screen will give you the instruction like a key name to open it or either you can try some default keys to open it. The default keys be like Esc, F7, F8, F9, F10, F11 and F12 you can try these keys one at a time by pressing it again and again after the 2 sec of your system starts and if the key is correct your boot menu will open.

Select your bootable Pendrive what you’ve made recently and press enter. In my case, I’ve made a bootable disc for me that’s why I’m selecting Cd-Rom drive in the example picture given below.

#2Select “Dos Programs”.

Right after when your Pendrive boots you’ll able to the screen like this so, just select the Dos Program in the main menu for now.

#3 –Now Select the “Next…” on the 9th No.

#4Select 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.

Solution #3 – Resting by Shorting Jumper

The another best way for resetting a bios password is to by shorting the bios or CMOS jumper. Yes shorting that bios jumper for 10 seconds can break your bios password and reset your bios too.

Normally you can locate this jumper nearby your CMOS battery or maybe beside the bios chip as named CLR_BIOS or CLRTC etc. and it’s look like the given image below.

So, now you’ll need to open your computer case and find that jumper. After that re-attaches that metal cover from 1-2 to 2-3 for 10 sec and after that move back the metal cover to 1-2 again.

After shorting, the password has been cleared and if it does then assemble back your computer’s case and starts your computer to load the default setting in the bios to make bios on its original position.

If the password still remains then try our last solution listed below.

Solution #4 – Resting by CMOS Battery 

All the CMOS and bios setting is saved in the bios chip which was attached 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. If you unplug or remove the battery for above 5 sec, the bios setting will be reset or cleared.

Step 1 – Unplug all the power supply which is connected to your computer. Means power cable.

Step 2 – Open your computer case.

Step 3 – Disconnect the CMOS battery.

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 metal wire because in some of the motherboard manufacturers backup the power to the Bios Chipset by using of some capacitor that’s why we short them to remove the remains power supply.

Step 5 – Reinstall the CMOS battery and assemble back your computer case and that’s it. Power up your computer and the bios got reset.

Note – Sometimes these solutions doesn’t work. In that case, you’ll have to re-install your bios software or replacing the bios chip.
