Hi Oleksij,

thanks for the hint. I installed and ran ASUS Live Update. It installed
2 components: ASUS Live Update v 3.1.9 and Fresco USB3.0 Driver v
3.5.4.0. I also did Windows 7 update (110 different updates, mostly
security related). After updates I repeated the tests I mentioned above.

Running Jpcsp on battery with maximum processor state set to 100% (with
87% charge) didn't cause crash. I repeated the test (84% charge) and
didn't get crash. I put AC cable back on and forced max processor state
to stay at 100%. I pulled AC cable off and didn't get crash.

But there are two things. I ran Jpcsp simultaneously with system monitor
and now CPU usage was all the time under 50%. Maybe the updates did
something to reduce CPU usage? I need to do more tests and for that I
need heavier application than Jpcsp, to test if heavier CPU usage still
causes crash. I also need to repeat the original test with lower battery
charge, since it seems that there might be a trend towards less stable
Windows 7 when battery charge is lower.

Title:
  Asus Zenbook UX31E powers off on plugin in/out AC adapter

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  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 with MS Windows either.
  And yes, there's enough power in my battery too, I can boot up and use the computer without AC adapter.

  syslog prints these lines to stdout in console, when plugin AC adapter first out and then in:
    [  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.
