Just a short note to say that I was having some problems playing a WMP HD video and after installing NHC that problem is gone. And for some reason I find the unit faster. To test that I ran again CrystalMark and I got a score of 18430.
This the first time that CrystalMark gives me a score higher than 18000. Before my scores were around 17900. So, my conclusion is that NHC changed my power profile for the UMPC connected to power and now it's running a lot faster.
