power cycling: computer shutoff time?
concerning using the reset button and power cycling, the textbook I am studying from says: "one disadvantage to power cycling is that certain circuits, such as memory chips, might need time to drain their charge for the reboot to be successful"
-sybex complete deluxe study guide for the COMPTIA A+ Exam, p. 30.
on average, how long might this be? what situations might I encounter in which I must wait this time period before starting the computer up again?

I find that just doing a complete power off and then turning back on has always been sufficient for any computer I've ever owned. I've never been one to subscribe to the theory that you have to have your computer of for 30 seconds.--

well my thinking is that if this statement is true, then immediately turning the computer on again will only prevent those certain circuits from fully rebooting, making this effect only pertinent when there are certain problems with those circuits. -

This is one of those things that sounds good on paper but in practice it makes no difference (in my experience). -

I've had a couple people who didn't get the different between restarting the computer and turning it off, so I've told people to turn it off for the count of five before, but that's the only time it's come up for me.

Cold boot vs warm boot. Look them up. There is a material difference and it can have real effects in a surprising amount of scenarios. The Sybex quote doesn't explain this in sufficient depth, from what you've quoted. The Wikipedia article on rebooting would be a good place to start.

The only issue I'm aware of when power-cycling a computer is the hard drive. I've often heard that it's hard on the drive motor to turn it back on when it's spinning down. I don't know if this is still the case with newer drives, but I wait 10 seconds.
