Lenovo: Partially Forgot BIOS & Windows Passwords

In this article, we will discuss how to deal with a situation where you have set a BIOS password on your Lenovo laptop, have partially forgotten it, and also need to access the Windows system which has its own password. We will cover the necessary steps to reset or recover both passwords without causing any damage to your device.

Resetting the BIOS Password

To reset the BIOS password on your Lenovo laptop, follow these steps:

1. Disconnect the AC adapter and remove the battery from the laptop.
2. Press and hold the power button for at least 15 seconds to drain any residual power from the laptop.
3. Insert the battery back into the laptop, but do not connect the AC adapter yet.
4. Press the Novo button or ThinkVantage button (depending on your Lenovo model) and connect the AC adapter while holding the button.
5. Release the button once the Lenovo OneKey Recovery screen appears.
6. From the recovery screen, select "System Recovery" and then "Reset BIOS Password" to clear the BIOS password.

Accessing Windows without a Password

If you have forgotten the Windows password as well, you can follow these steps to gain access:

1. Boot your Lenovo laptop and press F8 before the Windows logo appears to enter the Windows Advanced Options Menu.
2. Select "Safe Mode with Command Prompt" and press Enter.
3. When the Command Prompt window appears, type the following command and press Enter:
move C:\Windows\System32\utilman.exe C:\Windows\System32\utilman.exe.bak
4. Next, type the following command and press Enter:
copy C:\Windows\System32\cmd.exe C:\Windows\System32\utilman.exe
5. Restart your Lenovo laptop normally.
6. Once you are at the login screen, click the "Ease of Access" button located at the bottom left corner of the screen.
7. The Command Prompt window will appear. Type the following command to reset the Windows password:
net user [username] [new password]

Replace [username] with your actual Windows username and [new password] with the new password you want to set.

8. Close the Command Prompt window and log in using your new password.
9. Don't forget to revert the changes made to the utilman.exe file. Boot into Safe Mode with Command Prompt again and type the following commands:
copy C:\Windows\System32\utilman.exe.bak C:\Windows\System32\utilman.exe del C:\Windows\System32\utilman.exe.bak

• Write down your BIOS and Windows passwords and store them in a secure location.
• Use a password manager to securely store and manage your passwords.
• Enable biometric authentication methods, such as fingerprint readers or facial recognition, if your Lenovo laptop supports them.
