Let me clear up your clarification a bit.

First off, you're not supposed to copy Finders!  Anybody who's anybody
uses the Installer.  If you try to drag-copy system software onto your
machine from someone else's and you actually expect it to work, the
Macintosh Thought Police will laugh at you behind your back...

The Sleep menu item under Special is really threre.  When the System
senses that you're running on a Mac Portable, it makes the selection
become available.  If you either select `Sleep' or let the Portable
sit untouched for a while, it will go to sleep: the screen will blank,
the hard drive will spin down, and it will go into low-power mode
until you press any key.

I'm not sure how Pyro 4 does it; I haven't gotten a chance to play
with Pyro recently.  It might just add a menuitem of its own and
ignore the Sleep that's already available.  I wonder what happens when
you use Pyro 4 on a Portable?

The Battery DA brings up a small battery-power-level indicator.  The
batteries in the Mac Portable discharge at a steady rate over a long
period of time, allowing smart software to be able to estimate the
life left in them before a recharge is necessary.  In contrast,
batteries used in most MS-DOS portables tend to output steady power,
then discharge rapidly over a short interval of time; that's why no PC
laptops have battery-level indicators (except for a light that goes on
when the sudden power drop is seen).

Now, I hope *that* clears things up!  ;)
