I bought a ASUS netbook from Newegg for $289. Also added extra 1 mb of ram, not sure that did anything. I use it for my weather station server. I didn't want to leave a desktop on 24/7. After 300 hrs, my avg power consumption is 9.5 watt/hr. I keep it in the basement, w/the top closed. I use realVNC to access the desktop. Any guesses as to putting it on a timer, and say letting it run on battery for 6 hrs and change for six hours? Would this be a net energy saver or a wash, as to the higher drain when charging the batteries? I realize the batteries can only be charged so many times. Would it be better just to keep it plugged in all the time?
