Screen Flickering on All in One PC. Energy Efficient Intelligence issue?

This is a really crazy situation with a display monitor that I have running Win 8.  It has been flickering a bit I have noticed.  At first, I thought it was a driver issue or may be hardware.  I reverted back to the original drivers that cam with the machine since I know Windows Update has updated it recently with the latest Intel HD Drivers.  But it was to no avail. 

However, what intrigued me was somehow the HDMI in seem to be working flicker free.

I then stumbled upon this http://denis.doublebuffer.net/lablog/2012/11/19/fixing-the-screen-flickering-on-a-dell-inspiron-n5720-and-maybe-many-others/

It offered me an idea what may be wrong.  However, since my machine was not a laptop and cannot run on battery being an all in one, I was a bit lost.

I soon discovered a pattern, the flickering seem to start after a wake up from a machine sleep.  I then played around with the Energy Intelligent module that the machine runs in the background.  

I found if I toggle the settings to High by hitting the button with the leaf in the middle.

 The buttons would glow bright green and the re-toggle back to E mode with the button on the right.

The flickering would subside until the machine sleeps again and wakes up.

Seems like there may be a bug in this Energy Intelligence software, it is affecting the light in the LED when it is trying to save power.
