2). Since I get my power from Tinkertoy Power and Light which can have an outage on a clear 50 degree day, I often just power down to avoid an off and on outage and problems with getting the power right back and possibly frying the disk drive or something else. If the computer is sleeping and this occurs, would it be enough to trigger it to start back up at the same time the power is going off?

With the recent discussions on sleeping on MBPs and other models, I have some newbie questions.
- Are there any differences in this context from the sleep brought about by closing the lid and the shut down brought about by just not doing anything for awhile?
Check System Preferences->Energy Saver. You'll see that it is possible to specify only a display dimming after a certain time, separate to the setting for system sleep.
Quite simply - if the power light is pulsing, the system is sleeping, which is the same state regardless of how it is arrived at.

You're talking a laptop right? Then I'm sure it will continue its blissful sleep. The power supply circuit has enough damping and input protection[1] to handle quite unusual situations IME. I reckon you'd be safe leaving it on and plugged in. The switched mode power supplies used in the "power bricks" for these computers are also quite good at absorbing mild spikes and surges.
[1] I do recall an article on the testing laboratories used by Apple, which apart from cooking, vibrating and shaking Apple computers to destruction, also conducted a test which essentially pulled out and re-inserted the power plug on a laptop a few hundreds times in only a couple minutes. The quote from the engineer was something along the lines of "you never know what our users are going to get up to".

On the McBookPro, I don't know that I ever see the light pulsing. It
comes on, when I close the lid, but I don't think it pulses. Is this still sleeping? Also I have a USB hub attached and the light in the hub never goes out. Is this an indication that maybe it isn't sleeping in real life or is it just something to make me paranoid?(g).

Thanks for the information...

Put your ear on the lid. If you hear anything, it ain't sleeping. Certainly the hub being connected could make a diff.
