Poll – New (Unofficial) HotKey / Energy Management application

I’ve decided to write a new HotKey / Energy Management application because the official one provided by Lenovo still has major issues:

  • No OSD – I understand that they’ve wanted to follow the guidlines for the new Windows OS, and Fn+F5 – Airplane mode, Volume and Brightness have been successfully integrated into Windows but what about Webcam, Touchpad and Wireless Hard Key? Also, in my opinion, an option to use the standard wifi/bt switch would have been nice (Bluetooth state can only be changed from Charm menu (the one on the right side) -> Settings -> Change PC settings -> Wireless). Oh, and CapsLock notification is also missing.
  • Optimize For Battery Runtime / Best battery health does not work.

I’ve successfully written a (very basic) C# application which can communicate with the Lenovo driver, handle the HotKey events and change the battery mode. I want to add a nice GUI (Mac-like semi-transparent notifications on desktop and standard Windows 8 notifications in Metro mode) and further funtionality to the software.

What do you think about this project? By the way, these aren’t Lenovo IdeaPad S205 specific problems (see the Lenovo forum).

    The old Windows 7 Energy Management System, which is on the Driver CD works perfect for me on Windows 8.

    Ive encountered the (probably) most annoying issue with my s205 (E450 version)
    The Screen brightness floats like crazy. I’ve already turned off adaptive brightness, tested all versions of energy management available but i cant fix this issue. did anybody have the same problem?
