Is my laptop battery used while the laptop is in hibernation?

[Ryan Cabanas]

I was wondering, since hibernation saves all of my work to the hard
drive before shutting down, does the laptop use up the battery still
while in hibernation mode? If so, then that would mean that if I left
my computer in hibernation mode and the batter ran all the way out, I
could lose my work, right? Or would I not lose any of it because it's
been saved to the hard drive?

Thanks for the help.

You wouldn't lose it because it is on your hard disk.

The battery will usually be used by the real time clock, and the network
card (listening for startup commands).

No, the real time clock is controlled by the same kind of CMOS battery
as you find in a conventional PC. I have a laptop that I only
occasionally use outside my home office, and the only time I operate
it within the battery even in the unit is to replenish its charge just
before I'm going to go mobile or when I actually am mobile. Right now,
I'm typing this with no battery in on AC battery and my clock has
never ever wavered.

Your fist part is correct -- when you put a laptop in standby or
hibernation, it writes the contents of RAM to your HD and puts them
back when you turn it back on.

But in actuality, if you want to preserve your CMOS battery, if you
anticipate long periods where the battery won't be needed, the best
thing to do is take it out.
