How to Unlock Advanced BIOS Settings in InsydeH2O BIOS for 320-14IKB, 320-14ISK, 320-
#1
How to Unlock Advanced BIOS Settings in InsydeH2O BIOS for 320-14IKB, 320-14ISK, 320-15IKB (Type 80XL, Type 80YE), 320 Touch-15IKB (Type 80XN), 320-15ISK, 320-17IKB (Type 80XM), 320-17ISK, 520-15IKB (Type 80YL), Lenovo V320-17ISK, V320-17IKB (Type 80AH), B320-14IKB
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.

Long live the Lenovo IdeaPad series Big Grin !

I tried to use in my Ideapad 320-IKB type 81BG, 81BT, 81G3 and it didn't work.
When I run the Unlocker.exe a message appear “Incorrect Function”.
The Bios version is 6JCN33WW
How can I fix it?

I am not an expert, but here's what I would try to do: download LenovoH2O-Unlocker, run as admin, then power on while pressing F2 to access advanced BIOS settings on the mentioned Lenovo laptops. Use caution when adjusting settings, and reset to defaults if needed in the 'Exit' menu.
