Title:
  [LENOVO 4236SGS] suspend/resume failure

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After closing my laptop lid and allowing it to suspend to RAM, the
  system would not resume properly.

  The visuals on the GUI returned to its previous state without any
  artifacts, however the mouse pointer was not working.  I used a
  trackpad and a nipple on my T420 laptop. I left it in this state and
  the mouse was still dead after about 3-4 minutes.  After coming back
  from making a cup of tea the mouse moved but did not interact with any
  GUI elements.

  I have seens some success on previous ubuntu versions if I did a tty
  switch.  This did not work (ctrl+alt+F1), the Unity GUI stayed
  visible.  I then tried the sysreq triggers alt+sysreq RE and lost the
  mouse pointer again, but the gui stayed visible.  I needed to go
  through the whole alt+sysreq+reisub to make the machine reboot.
