Turning off your computer automatically is so
easy using a free program called
Handy
Tweakers. Among many features, there is a Turn Off
Tool which enables you to specify the exact time that
you want to turn off your computer so if you have a
download that takes a long time, defragmentation of a
big hard desk, encoding a video file or even burning a
DVD, you don't have to stay awake or keep your computer
running all night. Here is how.
