To use hibernate (or suspend2) requires your system to have a
kernel. If you are using such a kernel, then you should see the
in either* "/proc/suspend2"* or "*/sys/power/suspend2". *The kernel patch
will allow you to resume your system from your disk if you decide to use
Unfortunately, the* "tuxonice"* patch for the kernel is not available on
its website. This is what its website looks like(not very technical).
http://www.tuxonice.net/. I doubt running *"hibernate"* from the console
However, there is a github project that offers the patch.
https://github.com/pierre/tuxonice-fastboot. I will be checking this out
