no matter what state the computer is in, if it's plugged into power, it draws a current. even in completely "off" state, the computer still draws power to keep some things going. unless u actually disconnect it via relay that is. most ppl here i think use windows hibernate for "shut down" retains programs running and doesn't require as long of a boot time. it's still a good 10-15seconds on my machine. better than 30+seconds for a cold boot.
