When I have logged in to Unity and plug in or out AC adapter to Asus Zenbook UX31E, computer powers off. Sometimes this needs couple of tries (waiting or not waiting in between) when plugin in or out AC adapter.

This problem doesn't occur when I have switched to console or when in LightDM login screen. Problem doesn't happen in Windows either.
And yes, there's enough power in my battery too, I can boot up and use the computer without AC adapter.

syslog gives prints these lines to stdout in console, when plugin first out and then in the AC adapter:
  [ 869.521396] asus_wmi: Unknown key 57 pressed
  [ 874.704525] asus_wmi: Unknown key 58 pressed
  [ 876.993295] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id

What you also need:

1) lsb_release -rd
  Description: Ubuntu 12.04 LTS
  Release: 12.04

2) I could guess kernel, but it happens _only_ when I have logged in to Unity (or Unity 2D)...

3) I expect that my computer doesn't power off.

4) Computer powers off.
