Fix – Lenovo Active Protection System on Windows 8 and 8.1

APS Fix for Win8

Edit  (2013-07-24): Uploaded the x86 patch.

Download the patch for Windows 8 from here:

Edit (2014-02-06): Uploaded x64 & x86 patches for Windows 8.1.  This time I have uploaded only the patches – you can find the installers in the previous links. The installation procedure is almost the same except this time you have to reboot.

Download the patch for Windows 8.1 from here:


Lenovo has only released a ThinkPad version of Active Protection System for Windows 8 (Version
The latest version available for IdeaPad S205 on Lenovo Support (Version 1.70.11, Windows 7) is not compatible with Windows 8 (it crashes immediately due to compatibility issues).

Fortunately, I’ve found a way to run the APS on this netbook (and probably on other unsupported devices as well) by combining these two versions.
It turned out that the .cpl (Control Panel Extension) was the non-working module. I hope that Lenovo will release a proper, fixed version. Until then, here is a quick installation guide:


1. Run the APS 1.70.11 installer.
Select English when asked for language. Don’t change the default installation folder.
It isn’t necessary to reboot.
2. Run patch.bat
3. Reboot
4. Check Lenovo – Airbag Protection in Control Panel.

Supported devices (according to S205 Support page)

Lenovo B470, B570, V370, V470, V570, IdeaPad S205

Lenovo S205 BIOS Versions & NoWhiteList

I’ve uploaded all the officially available S205 BIOSs to GoogleDrive in the following structure:

  1. /[BIOS_VERSION].exe – The original Phoenix UEFI Flash Tool + BIOS ROM from  Lenovo (you can download it directly from Lenovo Support).
  2. /[BIOS_VERSION].sha, [BIOS_VERSION].md5 – Checksums. (Use these with e.g. Total Commander to verify the exe file’s integrity).
  3. /[BIOS_VERSION].txt – ReadMe file from Lenovo.
  4. /Extracted/ – [1] in extracted format (taken from C:\Users\[UserName]\AppData\Local\Temp\).
  5. /Extracted/WinFlash.sha, WinFlash.md5 – Checksums for the zip file.

These BIOSs are obviously safe to flash. If you have an older BIOS (you can check it on the BIOS home screen), upgrading to the latest (4BCN24WW) version may be a good idea, especially if you are planning to (re)install Windows 7 / 8. From the changelog:

Fix the hang up issue when installing non-OEM version Windows 7 Operation system.

If you’ve bought your S205 without any pre-installed operation system, you should wait for my upcoming tutorial on creating a bootable BIOS flashing pendrive.

Official Lenovo IdeaPad S205 BIOS:

  • 4BCN21WW (Version 21, 23 May 2011)
  • 4BCN22WW (Version 22, 27 July 2011)
  • 4BCN24WW (Version 24, 17 Aug 2011)

I wouldn’t recommend flashing the modded BIOS unless you want to replace your WiFi card or install a new WWAN (3G, 4G) card that is not supported by Lenovo (see the list of supported devices below). Flashing a modded bios can brick your laptop. Do it at your own risk!

Modded Lenovo IdeaPad S205 BIOS:

  • 4BCN24WW (Version 24, 17 Aug 2011) – NoWhiteList
    • The latest official BIOS with the WiFi/WWAN WhiteList removed.  WhiteList is a device filter in BIOS which prevents you from using any WiFi/WWAN card other than the ones on Lenovo’s list.
    • It has been confirmed to work with the Intel 6200 WiFi card (Lenovo FRU 60Y3191).
    • All credits go to Camiloml and BIOS-Mods. You can download it directly from their BIOS repository.

Lenovo S205 (Unofficial) Windows 8.1 Drivers (2014-12-31)

Windows 8 Logo

I’ve created this post to provide you the latest Windows 8 Drivers. Since Lenovo doesn’t support Windows 8 on our device, these drivers are either taken directly from the vendors or from other Lenovo notebooks’ official support. The plan is to update this page regularly so it would function as an unofficial S205 – Windows 8 support page. I’m going to upload the drivers to Google Drive as well.

Big thx to Romagnolo1973 for his tips.

Lenovo – No Official Windows 8 Support for S205 :(

Not Supported

This post is dedicated to Microsoft’s latest operation system: Windows 8.

It looks like even though Lenovo released the Windows 8 drivers for our laptop, they did not function correctly and now they’ve removed them from the support page and on Lenovo’s Windows 8 Upgrade Capable Systems S205 is listed as Not Supported. 😦

UPDATE: I’ve created a post to provide you the Windows 8 Drivers (different sources). The plan is to update this page regularly so it would function as an unofficial S205 – Windows 8 Support Page. I’m going to upload the drivers to Google Drive as well. 🙂

Driver Update – Ralink RT3090 WiFi Driver v5.0.2.0 with Windows 8 (!) Support

The new Ralink WiFi Driver is now available. Download it directly from Ralink Support.
Follow this tutorial to install the drivers properly.
