I got the distinction, just that I've never seen a computer do that. Now
somebody else posted a description of their Windows system that's different
from mine, which suggests configurations are different. Given that mine is
an ACPI machine, and ACPI says that if suspend-to-disk isn't handled in
hardware it must be handled in software, AND my machine (Dell inspiron 2500)
obviously doesn't handle it in hardware, I _think_ the behaviour you
describe is probably correct in some machines that do s2d in hardware, quite
possibly not all, but isn't correct in machines that do it in software under
Windows or Linux.
