I managed to install Ubuntu 15.10 on a new Lenovo 100S 11IBY Ideapad, a 32-bit cheap laptop that came with Windows 10 preinstalled and UEFI only boot system.

I followed this tutorial (response by Alexander Dubinsky). It worked flawlessly, but now I have three hardware problems I am not able to solve. I have searched tirelessly on Internet, but cannot find a solution.

The problems are:

  1. No sound card detected
  2. No wifi card detected (ethernet works fine though)
  3. No power management capabilities (battery tools don't work, but the laptop gets charged without problems, there's just no monitoring)

I would really appreciate if anyone can suggest a possible solution to any or all of these issues, particularly the sound card and wifi.

Here's my lspci output:

Running sudo aplay -l results in aplay: device_list:268: no soundcard found....

Running lspci -v | grep -A7 -i "audio" shows no results.

I have tried the different recommendations found here, But no success.

Can anyone help me please?

    Hadess has a mostly functional driver for this units WiFi. Google "Hadess driver sdio" or something. I have this exact same unit and I have the same sound problem I'm trying to figure out. Pulling out my hair. The battery monitoring is the last concern of mine right now. Please update with findings. –  Mar 22 '16 at 03:30
  • I have the same issues but on the ChromeOS version. Same access denied message, no sound at all – Bryson S. Apr 14 '17 at 07:14
