+What: /sys/devices/.../resource_in_use
+Date: January 2013
+Contact: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+Description:
+ The /sys/devices/.../resource_in_use attribute is only present
+ for device objects representing ACPI power resources.
+
+ If present, it contains a number (0 or 1) representing the
+ current status of the given power resource (0 means that the
+ resource is not in use and therefore it has been turned off).
+
+ This attribute is read-only.
