Is suspend the same as sleep?

[Space-Wolf]

To do the ubuntu equivalent of windows' sleep, you select "suspend" right?

[lotharmat]

That is correct - Suspend maintains RAM
Hibernate writes RAM to disk

Suspend uses more power than hibernate so will drain a battery quicker

Hope this helps

Thanks, that's exactly what I needed to know.

If it's supported on the hardware, the closest equivilant to the new Windows "sleep" command is:

sudo pm-suspend-hybrid

(or, as I like to call it, "hybridation").

It hybernates, then suspends.

Unfortunately my hardware doesn't support it so it does nothing.

Any ideas on how to get the pm-suspend-hybrid to be the default rather than pm-suspend?

I would like to setup my wife's laptop to pm-suspend-hybrid in case she can't get back to whatever she was working on, but I don't see an easy way to make this happen when she closes the lid in the power manager.

I actually have a few questions relating to this.

Is there a way to figure out how many amps suspend uses in comparison to hybrid?

For some reason, my laptop does nothing when I close the lid with Ubuntu running, even though power manager says it's supposed to hibernate. Is there any known fix for this?

Hibernate don't use any power because it's like power off.

The same.
Hybrid takes longer because it's hibernates the system too.
If you have a battery it makes no reason to use hybrid.
