How to Reset Lenovo with Best Lenovo BIOS Password Reset Tools

There are several Lenovo BIOS password reset utilities with how-to guides, each varying in complexity and risk. Please check them one by one.

Tool 1. Reset Lenovo BIOS Password with Backdoor Password

Lenovo laptops, like many other manufacturers, have built-in backdoor passwords that can be used to bypass the BIOS password. These backdoor passwords are typically universal and can unlock the BIOS without needing to perform any hardware changes.

Step 1. Power on your Lenovo laptop and press the required key (usually F1 or F2) to enter the BIOS setup menu.

Step 2. Try common backdoor passwords such as Lenovo, BIOS, password, or admin. If you fail three times, it will prompt with System Disabled.

Step 3. You may also need to search online for the specific backdoor password for your Lenovo model by going to https://bios-pw.org/. From here, you can put the code on the System Disabled screen to get possible backdoor passwords.

Step 4. Reboot your Lenovo laptop and press F1 to enter the BIOS access screen, then try these passwords. Repeat the process until you find the right backdoor password.

Tool 2. Reset BIOS Password in Lenovo with CMOS Jumper

The CMOS jumper method involves altering the motherboard's jumper settings to reset the BIOS password. Here's how:

Step 1. Ensure the laptop is turned off and disconnected from any power source. Then, carefully open the laptop casing to locate the motherboard.

Step 2. Find the CMOS jumper, typically labeled as CLR_CMOS, CLEAR_CMOS, JCMOS1. The CMOS jumper is usually near the motherboard’s battery. It consists of a small three-pin connector with a jumper covering two of the pins.

Step 3. Move the jumper from its default position (usually covering pins 1 and 2) to pins 2 and 3 for about 10-20 seconds. This will reset the BIOS settings, including the password.

Step 4. Put the back panel back on, reattach the screws, and reconnect the power cable. Power on the laptop to check if the BIOS password has been reset.

Tool 3. Reset Lenovo using BIOS Reset Software

If you prefer a more straightforward and automated solution, using BIOS reset software can be a great option. Many programs, like CmosPwd and CMOS De-Animator, are available online and can reset the password for you. You could search and choose one according to your needs.

Note: This option requires you to get a reliable Lenovo laptop BIOS password reset tool and a bootable media for device boot.

Step 1. Get the Lenovo laptop BIOS password reset software free download on your computer.

Step 2. Create a bootable USB drive with the BIOS reset software. This process may require a different computer and USB bootable software to make the drive bootable.

Step 3. Configure the laptop to boot from the USB drive. Once the BIOS reset software loads, follow the on-screen instructions to reset the BIOS password.

Tool 4. Reset Lenovo BIOS Password by Removing CMOS Battery

If the above methods don’t work or you prefer a more hands-on approach, you can reset the BIOS password by removing the CMOS battery. This method works by draining the stored power from the battery, which will reset the BIOS settings.

Step 1. Shut down your Lenovo laptop and unplug all cables, including the power adapter and battery (if removable).

Step 2. Use a screwdriver to remove the back panel of the laptop and locate the CMOS battery. The CMOS battery is usually a coin-cell battery, similar to a watch battery.

Step 3. Carefully remove the CMOS battery from its holder. You can use a plastic tool or your fingers to detach the battery.

Step 4. Let the laptop sit without the CMOS battery for about 5-10 minutes. This will ensure that all the settings, including the BIOS password, are reset.

Step 5. After waiting, reinsert the CMOS battery into its holder and reassemble the laptop. Power on the laptop, and you should no longer be prompted for the BIOS password.
