Kindle 1, to put to sleep press the Alt and the Text key at the same time... press the same keys to wake it up
Another way to put your Kindle to "sleep" is to simply leave it alone. It will put itself into the sleep mode all by itself after a time of inactivity (about 10 minutes?)
Kindle 2 and DX, to put to sleep, slide the top switch to the right, then let go... same to wake it up.
To turn the Kindle completely off, slide and hold the top switch for several seconds until you see your Kindle go off. There really isn't any need to turn it completely off unless you need to reset it for one reason or another. The only time the Kindle actually uses any power is when you are "turning" pages, or using the Whispernet. I can't tell you (or remember) the last time I turned mine off completely... makes me nervous just thinking about it.
