How to Get Into Lenovo BIOS

By Jackie Bailey

Learn how to enter your Lenovo's BIOS by completely shutting down your system while holding the Shift key. Restart and press F1 or F12.

To access the Basic Input Output System -- the software that runs before Windows or Linux boots -- from your Lenovo computer, you must completely shut down the system. BIOS is firmware and runs the hardware of the computer.

Enter BIOS Upon Restart

Step 1

Hold down the Shift key while shutting down Windows 8. This keypress overrides the default hybrid shutdown and completely shuts down your system.

Step 2

When you restart your system, press either F1 for the Setup Utility or F12 for the Boot Menu. Both the Setup Utility and the Boot Menu are parts of BIOS and not your operating system.

Tip

Some models of Lenovo computers or other manufacturers may use different keys to enter BIOS.

Disable Fast Startup

By disabling fast startup, your system will completely shut down when you turn off your computer without holding down Shift while clicking Shut Down. This will allow you to enter BIOS upon restarting your computer.

Step 1

Go to Control Panel and click Power Options.

Step 2

Click Choose What the Power Button Does.

Click Choose what the power button does.

Step 3

Turn off Fast Startup and choose Shut Down.

Choose the Shut Down option for the power button and disable fast startup.

Tip

Once you disable fast startup on your Lenovo, you can enter BIOS by restarting your computer normally and pressing F1 for the Setup Utility or F12 for the Boot Menu.

Understand BIOS

Warning

Do not make changes you do not fully understand. Serious damage to your Lenovo's system can result from making mistakes in BIOS setting adjustments. Mistakes can cause your operating system to completely stop working. If your operating system stops working due to BIOS issues, you will need to replace your computer.

Pressing F1 to enter your Lenovo BIOS will take you to the Main Menu of your Setup Utility. From here, you can view information on the BIOS version on your Lenovo. The Setup Utility allows you to configure your Lenovo hardware, adjust the system date and time, and configure the security options on your Lenovo hardware. The Setup Utility is also where you set up what happens when you boot up your computer. You can then save or discard changes, load the Setup defaults or exit the Setup Utility.
