For laptop users, a BIOS password is an excellent way of ensuring that other people don't modify your system settings or change or delete various passwords. However, if you use your laptop primarily at home or in another area where the security of your notebook or its data is not a major concern, disabling or removing the password may make your laptop easier to use. This is especially true if you must enter a BIOS or Supervisor password to access the operating system on your laptop.
Shut down the laptop. Wait a few seconds, and then power it on again.

Press the key required to enter the BIOS area of your laptop. The key you need to press varies depending on your notebook's manufacturer. Refer to your owner's manual. Alternatively, look for a prompt on the initial boot screen that displays the key you need to press.
Enter the current BIOS password for the laptop when prompted to do so.
Click the "Password" or "Security" tab in the BIOS setup menu, and then click the "Supervisor Password" or "BIOS Password" option. Click the "Change Password" or similar option.
Enter the current BIOS password again, and then press the "Enter" key. When prompted to enter a new password, just press the "Enter" key without typing anything in the password field. Repeat if prompted to confirm the blank password.
Click the "Save Settings" option in the BIOS menu screen to save changes and exit the utility. The laptop should no longer prompt for a BIOS or Supervisor password.
If you plan to use your laptop outside your home or other secure area, create a new BIOS password before doing so.
