[Bug 1552891] [NEW] System freezes after closing lid on Thinkpad X260

 

Public bug reported:

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.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: New
