+What: /sys/bus/acpi/intel-rapid-start/wakeup_events
+Date: July 2, 2013
+KernelVersion: 3.11
+Contact: Matthew Garrett <mjg59@srcf.ucam.org>
+Description: An integer representing a set of wakeup events as follows:
+ 1: Wake to enter hibernation when the wakeup timer expires
+ 2: Wake to enter hibernation when the battery reaches a
+ critical level
+
+ These values are ORed together. For example, a value of 3
+ indicates that the system will wake to enter hibernation when
+ either the wakeup timer expires or the battery reaches a
+ critical level.
