Navigating the BIOS Interface
Once you successfully access the BIOS, it’s important to know how to navigate its interface. The BIOS UI may differ slightly depending on your laptop’s model or BIOS version, but the general layout remains consistent.
Understanding BIOS Menu Options
The BIOS menu is typically divided into several tabs or sections that allow you to make different configurations, such as:
- Information: Displays system information like BIOS version, processor details, and memory status.
- Configuration: Allows you to make changes to hardware settings such as boot options, secure boot, and virtualization support.
- Security: Provides options for setting passwords, enabling or disabling secure boot, and other security parameters.
- Exit: Options available to save changes and exit, exit without saving, or load default settings.
Common Configurations in BIOS
Here are some common BIOS settings you might want to adjust:
Boot Order
Setting the boot order is crucial if you want to boot from a USB or an external drive. Here’s how you can change it:
- Navigate to the Startup or Boot Order tab.
- Use the arrow keys to select the boot device.
- Adjust the boot priority accordingly, usually placing the USB drive before the hard disk.
Virtualization Technology
If you plan to use virtual machines, enabling virtualization in BIOS is essential:
- Go to the Configuration tab.
- Look for Intel Virtualization Technology or similar and set it to Enabled.
Saving Changes and Exit
After making necessary changes in BIOS, it’s crucial to save your settings:
- Navigate to the Exit tab.
- Choose Save Changes and Exit.
- Confirm your choice when prompted.
Your laptop will restart with the new settings applied.
Troubleshooting Common Issues
Sometimes, users encounter difficulties when trying to access the BIOS. Here are the most common issues and their solutions:
Issue: BIOS Not Opening
If your laptop doesn’t enter the BIOS despite pressing the F2 key, consider the following:
- Try Different Key: Certain Lenovo models may require you to press the F1 key instead.
- Fast Boot Option: If your laptop has fast boot enabled, it can skip the BIOS access. Disable it through Windows settings or perform a power-on self-test (POST).
Issue: Changes Not Taking Effect
If changes in the BIOS do not seem to apply:
- Ensure You Save Changes: Always confirm that you’ve chosen to save your changes before exiting.
- Restore Default Settings: If issues persist, consider restoring BIOS settings to default and reapplying the necessary changes.

To access the BIOS on your Lenovo Ideapad 100s, start by powering off your device completely. Once it’s off, turn it back on and immediately begin pressing the “F2” key repeatedly. You have to be quick, as the window to press this key is typically short. If you see the Windows logo, it means you have missed the chance, and you will need to try again by restarting your laptop.
If you prefer an alternative method, you can also access BIOS using Windows. Go to “Settings,” then “Update & Security,” and click on “Recovery.” Under the “Advanced startup” section, select “Restart now.” Once your device restarts, navigate to “Troubleshoot,” then “Advanced options,” and finally “UEFI Firmware Settings.” Click on “Restart,” and your computer will boot directly into the BIOS setup.
What should I do if my Lenovo Ideapad 100s won’t enter the BIOS?
If your Lenovo Ideapad 100s is not entering the BIOS despite pressing the “F2” key, there are a few troubleshooting steps you can follow. Make sure your keyboard is functioning correctly, as sometimes external keyboards or USB connections can interfere. It might help to try using the built-in keyboard instead if you have an external one connected.
Additionally, consider performing a power cycle on the laptop. Turn off the device, unplug it, and remove the battery if possible. Hold down the power button for about 15 seconds to drain any residual power and then reconnect everything. Once done, try again to access the BIOS using the “F2” key upon startup.
Can I change boot settings in the BIOS of my Lenovo Ideapad 100s?
