Title:
  System freezes after closing lid on Thinkpad X260

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My current Ubuntu version is 14.04.4 but I also tried 15.10.
  Regardless of the Ubuntu version there is a serious problem with my new Thinkpad X260 when it is in battery mode and I close and reopen the lid. The problem is not affecting the suspend mode as it still occurs when this mode is disabled.

  what I expect to happen: After closing the lid the screen goes off.
  When I open the lid again, screen goes on and I can use the laptop.

  what happens every time: When I close the lid the screen turns black.
  When I open the lid again the screen displays the system but it is
  frozen and does not react on input.

  Interestingly I can not reproduce this problem when the laptop is connected to an AC power source.
