Hi there.. I'd want to know if i can suspend to ram my system for 30m (for example) and auto wake-up it then that time is over. Is there any possibility to do that? What parts of the kernel still running during the sleep process? Thanks!

I have searched around a while ago and found no other solution that wol (wake over lan) or let the computer run by itself.
Cron is your friend.

Mmmmm... cron is a good solution, but i really need my system to consume very low energy, that means, it'll have to be turned off or suspended.

Why not suspend to disk?
Suspended system, but no power consumtion

Well, then tell me how I suspend to disk the system for a while, and make it auto wake-up?

Seems I understood you wrong...
Was thinking of a laptop that gets awaken to be properly shut down when not used for a specific time.... sorry

You could look up the command "rtcwake".
I think that will do what you want.

I had problems with the system not waking up correctly after
rctwake -s 10 -m mem
but when doing
rtcwake -s 10 -m no
sudo pm-suspend
It worked to perfection. This can be found on google but I'll post it here just in case somebody else needs it.
Oh, and suspend-to-disk and wake-up through the bios is also a solution for the OP, although that works better when you have a set time for it to wake up every day than a set amount of seconds it will be sleeping, where rtcwake shines.

I with I could do that... Unfortunately, the timer seems to not make an interruption. When I execute:
[sironi@laptop ~]$ rtcwake -s 10 -m on
rtcwake: assuming RTC uses UTC ...
rtcwake: wakeup from "on" using /dev/rtc0 at Wed Mar 31 02:11:08 2010
The command never ends. I tried changing hardware clock, but it still doesn't working. Im frustrated...
