If you can show me how to close a desktop's or minitower's
When APM was the standard for those functionalities, it
worked perfectly at the time APM had been obsoleted. I
assume the same thing regarding ACPI will be the same:
When it works, it gets replaced by something else.

Depends. Sometimes you might intend that closing the lid
doesn't cause _any_ action, and the power button to be
the power button (causing a shutdown). Exanple: You are
using the laptop with external keyboard, mouse and screen.
To avoid the internal keyboard to become dusty, closing
the laptop would be nice. And if you're done with the
work - also applies when used "normally" - press the
power button, close the lid, and the device will power
down in few seconds.
Modern laptops don't seem to be able to perform like that.
If you press the power button, maybe they shutdown. If
you close the light right after that, it will go into some
sleep or hibernate mode _during_ the shutdown.
As far as I know, many of such functionalities depends
on the ACPI implementation. Here, manufacturers often
do a crappy job, not caring for specifications and standards.
This may often render parts of the device useless.

Live file systems like FreeSBIE produced good results
when the underlying OS was recent. 3D and current drivers
might be a problem today.

Of course, but if you are interested in utilizing the
new system's full functionality, being able to also load
kernel drivers (such as nVidia and ATI) could also be a
