+Sleep states summary (thanx, Ducrot)
+====================================
+
+In a really perfect world:
+echo 1 > /proc/acpi/sleep       # for standby
+echo 2 > /proc/acpi/sleep       # for suspend to ram
+echo 3 > /proc/acpi/sleep       # for suspend to ram, but with more power conservative
+echo 4 > /proc/acpi/sleep       # for suspend to disk
+echo 5 > /proc/acpi/sleep       # for shutdown unfriendly the system
+
+and perhaps
+echo 4b > /proc/acpi/sleep      # for suspend to disk via s4bios
