This is a laptop Dell Vostro 3550 with BIOS A12 (SandyBridge). External LCD
hooked via HDMI, internal LCD panel turned off.

What could trigger the issue? Fully loaded both CPU cores (for a week or so),
time to time my external screen goes blank after I leave the computer for a
while. It could have happened when I came back and woke up the X11 screen or
even, turned on the power button of the external HDMI. In general both
scenarios happen and I do not know what I was doing at about that time. Any of
these could me related to the issue but it is a wild guess.
