22 watt of idle power is actually not that impressive. PowerTop claims my 17-inch Dell XPS, with a Core i7 2630QM and an nVidia GeForce GT555M can manage 10 watts when it's not doing anything and screen brightness is lowered. Most of that power savings comes from spinning down the hard drives, and the discrete GPU, but since the reviewed laptop has an SSD, it doesn't make much difference. I don't understand where the 22 watts comes from.
