I experimented with both "sleep" and "hibernate" modes. Frankly, as
far as power usage is concerned, I don't see any difference. In both,
the display, hard drive and cooling fans stop operating.

There is a little more power being used in sleep mode as it needs to keep
power going to memory. Eventually, the batteries will drain, and it will
switch to hibernate mode. Not a concern for a desktop, but it is of
minor concern for a laptop.

Personally, I keep my desktops running 24/7, but not my laptops. I don't
really think they were built with the necessary cooling. I did manage to
fry an old Thinkpad. A capacitor melted. It might not have been
inadequate cooling, as there were a bunch of defective capacitors out
there when the Thinkpad was made.

They RAM is powered during *hibernate* also.
