When it's in sleep mode, your computer's monitor and disk drives are
shut down. Current continues to flow to RAM memory, so that its
contents are preserved. This allows it to wake up quite quickly, but
because there is a small current drain, you can't do it forever.
When you hibernate your computer, the contents of RAM are written out
to a disk file, then the computer turns itself off. No current is
used, so you can leave it hibernated as long as you want. Because it
has to read all that data from the disk drive, restarting from
hibernation takes a bit longer than restarting from sleep.
You're not going to scratch the disk drives either way (unless you
*really* bash your backpack around)! Sleeping it for several days will
drain the battery. I think that if the battery gets too low, the
computer will automatically hibernate.
One warning: I don't understand why this happened, but I recently left
my computer in sleep mode for a couple of days. I don't normally do
this, but this time I put it down and forgot about it. It restarted
fine, but a couple of minutes later, the screen went gray and the
machine locked up hard. I had to cut power (push and hold power
button) to shut it down, then restart it. That doesn't mean it will
happen to you, but strange things do happen....
