No, that is not it. I unplug the headset after I did a hibernation test. Still not going to Hibernation. In order to accelerate the hibernation test process, I also tried to test the hibernation with a free software called sleeper from passmark. Here is the test software I used. http://www.passmark.com/products/sleeper.htm. The problems: if boot normally, It will just go into a blue-green. If I clean boot it, it won't wake up, after sleep, but still it won't go into hibernation either. So I still need to find out how to interpreate the report and narrow down the cause.
