Step-by-Step Guide: Accessing the BIOS on a Lenovo Laptop

Here’s a step-by-step guide on how to go to BIOS on a Lenovo laptop:

1. Power Down Your Laptop: Completely shut down your Lenovo laptop. Ensure it is not in sleep or hibernation mode.

2. Locate the Novo Button (Optional): Some Lenovo laptops have a small button labeled “Novo” or a similar designation, usually located near the power button or on the side. Pressing this button while the laptop is off will bring up a boot menu, where you can select “BIOS Setup”.

3. Identify the Correct Key: For laptops without the Novo button, you need to identify the correct key to press during startup. Common keys include:

   • F2
   • Delete (Del)
   • F12
   • Fn + F2 (on some models, especially older ones)
     The key displayed on the screen during startup, if any, is the one you need to press.

4. Power On and Press the Key Repeatedly: Turn on your Lenovo laptop. Immediately begin pressing the identified key repeatedly until the BIOS setup utility appears. Don’t hold the key down; tap it continuously.

5. Navigate the BIOS: Once in the BIOS, use the arrow keys to navigate the menus and the Enter key to select options. Read the on-screen instructions carefully.

6. Save and Exit: When you are finished making changes, navigate to the “Save & Exit” menu and select “Save Changes and Exit.” This will save your changes and restart your laptop.

Alternative Method: Accessing BIOS from Windows

If you can’t access the BIOS using the startup keys, you can also try accessing it from within Windows:

1. Open Settings: Click the Windows Start button and select the Settings icon (the gear icon).
2. Go to Update & Security: In the Settings menu, click on “Update & Security.”
3. Select Recovery: In the left-hand pane, click on “Recovery.”
4. Advanced Startup: Under “Advanced startup,” click the “Restart now” button.
5. Choose an Option: After the restart, you’ll be presented with a “Choose an option” screen. Select “Troubleshoot.”
6. Advanced Options: On the “Troubleshoot” screen, select “Advanced options.”
7. UEFI Firmware Settings: Look for an option called “UEFI Firmware Settings“. If you see it, click on it. If not, your laptop might not support booting to BIOS from Windows.
8. Restart: Click the “Restart” button. Your laptop will then restart and boot directly into the BIOS setup utility.

Common Mistakes to Avoid

• Missing the Key Press Window: The window to press the BIOS key is very brief (often only a second or two). Make sure you start pressing the key immediately after powering on the laptop.
• Pressing the Wrong Key: Consult your laptop’s manual or Lenovo’s support website to confirm the correct key for your specific model.
• Holding the Key Down: Holding the key down can sometimes prevent the BIOS menu from appearing. Instead, tap the key repeatedly.
• Not Disabling Fast Startup: Fast Startup in Windows can sometimes interfere with the BIOS access process. Try disabling Fast Startup in Power Options if you are having trouble.

BIOS Key Variations by Lenovo Series

While the F2 and Delete keys are common, the specific key can vary depending on the Lenovo laptop series. Here’s a table illustrating some key variations:

Lenovo Series	Common BIOS Key(s)	Notes
ThinkPad	F1, Enter	Press Enter at startup to access the startup interrupt menu, then select BIOS Setup. F1 often works too.
IdeaPad	F2	Most common key.
Legion	F2	Check the quick start guide or the screen on boot for the specific key.

Disabling Fast Startup in Windows

Fast Startup, while speeding up boot times, can interfere with accessing the BIOS because it doesn’t fully shut down the system. Here’s how to disable it:

1. Search for “Control Panel” in the Windows search bar and open it.
2. Go to “Power Options”.
3. Click on “Choose what the power buttons do” on the left-hand side.
4. Click on “Change settings that are currently unavailable”.
5. Uncheck the box next to “Turn on fast startup (recommended)”.
6. Click “Save changes”.

After disabling Fast Startup, try again to access the BIOS using the appropriate key.
