No, the laptop still has power when doing that, due to the battery.

Power outage
power outage (also known as power cut, power failure, power loss,
or blackout) is the loss of the electricity supply to an area.

A power outage does not affect battery powered devices, obviously.

As your definition aptly explained, a power outage is an idiom and
whether or not a device has a battery doesn't change whether or not a
power outage has taken place.

But a Mac laptop doesn't hibernate when a power outage takes place, it
does so when it predicts that it will take place and actually shuts
down before it taking place.

A Mac laptop will not save its state and then wait for the power
outage, it will save its state and then shut down, avoiding the "power
outage" completely.

This sentence:

"In a Windows machine, if there is a power outage, the machine
goes into normal hibernation"

Can - according to me - only be interpreted as power being cut from
the machine due to power failure (as described above). Since laptops
are battery powered then this scenarion doesn't affect them.

Of course it affects them, because as the definition you provide it
aptly put it a "power outage" "is the loss of the electricity supply to
an area."

But when my area has no power, my laptop still does.

Further more, the wording suggest that the act of hibernation is a
result of the power outage, which of course isn't true with a Mac
laptop. It doesn't go into hibernation mode when power is being
removed (either unplugged or battery removed) since it goes into
hibernation when the power source is close to fail, not when it fails.
This is of course due to the fact that it can predict that failure in
advance, which isn't true of a power outage (as defined above).

The hibernation *is* a result of the power outage when one occurs. If
the power didn't go out, the battery wouldn't run down and the machine
wouldn't have gone into hibernation. The fact that the result takes a
little time doesn't change that it is a result of the loss of AC power.

You're bending the English language out of shape here, Alan.

If power is cut (i.e. cord removed or battery removed) no computer
will manage to go into hibernation mode that I know of.

If power is not removed (i.e. cord not removed or battery left in
laptop) no hibernation is needed.

On top of that, when a mac laptop in sleep mode detects that the
battery level will soon fail, it will save its state and shut down.

So in short, the hibernation mode of any Mac laptop is totally
dependant on the battery. Remove the battery and then unplug the
machine and it will not go into hibernation mode.

But yes - it "amounts" to the same thing. I am countering the quote
from zara that windows machines goes into hibernation mode when there
is a power outage. They don't.

I agree that normal Windows desktops don't (how could they? where would
they get the power? to keep the hard drive going?)
