You miss the point, external monitors are expected to have their *own*
wall-power cord. Therefore the laptop is not expected to give them
enough power to run their display.
Yes, a minimal amount of power will remain in use by the video card
itself, to send its own signals in the new direction. But if your
backlight power cost is significant *at all* then using the external
mode will negate that cost; whatever gain that's worth, you will get.

Yes, but very nice to "put it in silent mode" if you need to edit on
the train and you have a tendency to make vi beep a bit.

It means if you have some random device attached to the builtin parallel,
which for its own putzy reasons can't take full speed parallel data, this
is the way you could improve that.
No affect on PCMCIA slot. I'm not sure that model takes 32bit (cardbus)
cards, it might only take 16bit (pc card) cards.

In order to do any macro-ing on the Fn key you would need to know what
keycode it generates. When "windows keys" were new they were the same
problem, and people had to hunt up (via showkeys or otherwise) that they
weree scancode 106. (or is that the menu key. I forget.)
showkeys is a console utility.
