+      Suspend to RAM allows the system to enter sleep states in which main
+      memory is powered and thus its contents are preserved. The method cuts
+      power to most parts of the machine aside from the RAM.  Because of the
+      large power savings, it is advisable for laptops to automatically enter
+      this mode when the computer is running on batteries and the lid is closed
+      (or the user is inactive for some time).

+      
+    <para>
+      Suspend to disk (Hibernation) saves the machine's state into swap space
+      and completely powers off the machine. When the machine is powered on,
+      the state is restored. Until then, there is zero power consumption.
+      Suspend to RAM and hibernation are normally appropriate for portable
+      devices such as laptops, but can be used on workstations.  The capability
+      is not really appropriate for servers.
+    </para>
+
+    <para>
+      To use hibernation, the kernel parameter
+      resume=/dev/&lt;swap_partition&gt; has to be used on the kernel command
+      line (in grub.cfg).  The swap partition should be at least the size of
+      the physical RAM on the system.
