Is there such a thing as a Win8 Comp? Satisfaction Obtained

This link might help. This guy actually got Best Buy to do it - eventually - but he also tells how it was done as you read along in this thread. It is worth a look at your BIOs screen menu when you have the laptop back in your hands to see if these same settings are there.
