Bug Description
Update (2014-Aug-09): An external display connected via VGA port would turn on when the system resumed from suspend, but the primary screen (and possibly backlight) remained blank.
------------------
When resuming from suspend, the PC's screen remained blank. However, everything else seemed responsive, as I was able to log in and turn up/down the volume via shortcut keys and got an audio response.
