  You don't say for which type of computer, but 'knowing' you, you
probably are asking about laptops, so I will respond in that context.

  As Shinji Ikari said, when in hibernation, the laptop still uses a
little power, because for example it responds to the power button, which
is a soft(ware) button, not an actaully switch. So the electronics of
the laptop is still ppartly on and hence uses some power. And, as
mentioned, USB ports might be kept alive, which also draws power.

  And, for Windows 10 (and 11), the laptop can have 'Modern Standby'
[1], which is more awake than 'old' 'Sleep'. And if the laptop has
'Modern Standby', it can also have 'Adaptive Hibernate' [2]. When in
Adaptive Hibernate, the system can still be woken up a bit (read the
reference) and can/will use some power, by default not more than 5% per
cycle.

  So yes, in hibernation, the laptop can and probably will use some
power.

  OTOH, in hibernation, the laptop can survive without power, which is
proven if you remove the battery (and of course not have the laptop on
AC power), assuming you can remove the battery, which is often no longer
the case. If, after doing that, you re-insert the battery or/and connect
AC power, you can wake the laptop by pressing the power button and the
session will continue, exactly as you  left it.

  There's no reason and no, it's not dangerous. Most knowledgeable
laptop users use it all the time (as has been recently discussed in
these groups (10 or/and 11)), because it's so much more convenient than
Shutdown, reboot, login and restart/initialize all your stuff to where
it was and uses much less battery power than the only other alternative,
which is Sleep and re-awake.

  Hope this helps.
