7001da177e4SLinus Torvalds	  APM is a BIOS specification for saving power using several different
7011da177e4SLinus Torvalds	  techniques. This is mostly useful for battery powered laptops with
7021da177e4SLinus Torvalds	  APM compliant BIOSes. If you say Y here, the system time will be
7031da177e4SLinus Torvalds	  reset after a RESUME operation, the /proc/apm device will provide
7041da177e4SLinus Torvalds	  battery status information, and user-space programs will receive
7051da177e4SLinus Torvalds	  notification of APM "events" (e.g. battery status change).
7061da177e4SLinus Torvalds
7071da177e4SLinus Torvalds	  In order to use APM, you will need supporting software. For location
7081da177e4SLinus Torvalds	  and more information, read <file:Documentation/pm.txt> and the
7091da177e4SLinus Torvalds	  Battery Powered Linux mini-HOWTO, available from
