Title:
  [LENOVO 20A7005JMB] suspend/resume failure

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  It seems the resume only works with usb3 disabled

  
  cat /proc/version_signature => Ubuntu 3.13.0-17.37-generic 3.13.6

  
  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04

  
  ------

  When going to suspend on an X1 Carbon (20a7) the suspend seems to
  work, however, the adaptives keys stays on, and the system does not
  respond to power key press.

  Needing forced shutdown instead this might be related with usb2/usb3
  automatic routing
