How to Reset the Vaio BIOS Password

Save

Just as you can set a password for your email account or online banking, it is also possible to set a computer password in the BIOS. The BIOS, or basic input/output system, is the first computer code that the computer runs when starting up. The computer's motherboard stores this password and requires you to enter it before the computer will load the operating system. Setting up a BIOS password is one method of discouraging unauthorized access but, unlike the Internet, there are no hints or recovery options for forgotten BIOS passwords. Instead, you must reset your motherboard BIOS to clear the password.

Things You'll Need

  • Flathead screwdriver
  • Phillips screwdriver
  • Shut down the Sony Vaio PC. Unplug the power cable and any other cords attached to the computer.

  • Grip the left side panel and pull it away to reveal the internal components. There may be a lever near the cover you must press down or a set of screws on the cover you need to remove with a Phillips screwdriver.

  • Pry out the CMOS battery gently with a flathead screwdriver. Look for the battery on the motherboard. It is similar in shape and color to an American quarter.

  • Remove the battery, wait 30 minutes, then replace it. Unplugging the power source and removing the CMOS battery for half an hour will reset all BIOS settings to the factory default, including the BIOS password. Since by default computers do not have a BIOS password, this removes the password.

    Replace the system cover and cords. If you wish to add a password to the computer to replace the old one, you must go into the BIOS and enter it.

Tips & Warnings

  • Removing the battery resets all BIOS settings to the factory default.
  • Before touching any components of your computer, be sure to ground yourself to discharge any static buildup. Static can damage electronics.
