This is a guide on how to unlock the advanced BIOS settings in the Lenovo laptops listed above. It is super easy and done very fast!

Downloading and Running LenovoH2O-Unlocker

  1. Download the LenovoH2O-Unlocker application from here, source is from GitHub.
  2. Open Windows Explorer.
  3. Go to the Downloads folder or to the folder where you downloaded it to.
  4. Right-click the Unlocker.exe file and click Run as Administrator. Without administrator rights, it is guaranteed that it fails.
  5. Let it run. If it succeeded it should say success.

Booting Into the BIOS

  1. Power off your Lenovo laptop.
  2. Power on, but after you press the power button immediately keep pressing the F2 button until the BIOS appears, saying ‘InsydeH2O Setup Utility’.
  3. Congratulations! There should be three new tabs: ‘Main’, ‘Advanced’ and ‘Power’ with many new options.
    You can change many settings in the BIOS now. They will stay even after you boot into the BIOS again. But also be careful, as some settings might make your system not to function properly anymore. If that is the case, you can go to ‘Exit’ > ‘Load OS Optimized Defaults’ to reset all settings to the defaults.

Did you try this guide? It could work, as long as it is a Lenovo device.
