It is difficult to speak about benchmark, as soon as we are talking 
about idle power. I think the first step evaluation could be made with 
vendor provided data, as it mostly depends on hardware. If vendor speaks 
about 2 hours on battery, then there is quite small probability to get 
much out of that system, as it looks mostly positioned as desktop and 
may have many desktop components. And opposite, system declaring 9 hours 
must support a lot of different power-saving technologies to reach it.
