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.
