how to wake up from S3 acpi sleep state?

When typing
echo 3 > /proc/acpi/sleep
acpitool -s
echo mem > /sys/power/state

my laptop goes to sleep as expected.

However, i don't know how to wake it up. When pressing the power button, everything goes up again but just to power off.

How can i just wake it up and not turn it off?
ANd how can i wake it up from the keyboard?

Right before you go to sleep, try disabling the ACPI daemon:
# /etc/rc.d/init.d/acpid stop

Sometimes there are BIOS options to tell the system which devices can wake up the system from sleep. However, you may find out that the power button might be the only way.

Actually I forgot to add that you can also try removing the button module. This is what I do and it works correctly.

/etc/rc.d/init.d/acpid stop
/sbin/modprobe -r button
echo 3 > /proc/acpi/sleep
/sbin/modprobe button
/etc/rc.d/init.d/acpid start

You'd better disable the acpid action which shuts down your system when pressing the power button. It might be defined in /etc/acpi/ or in one of the files in /etc/acpi/actions/.

Do you have a Fn key (or similar)? Here pressing this for ~ 1 second brings my laptop back up after sleep.
