+         APM is a BIOS specification for saving power using several different
+         techniques. This is mostly useful for battery powered laptops with
+         APM compliant BIOSes. If you say Y here, the system time will be
+         reset after a RESUME operation, the /proc/apm device will provide
+         battery status information, and user-space programs will receive
+         notification of APM "events" (e.g. battery status change).
+
+         In order to use APM, you will need supporting software. For location
+         and more information, read <file:Documentation/pm.txt> and the
+         Battery Powered Linux mini-HOWTO, available from
+         <http://www.tldp.org/docs.html#howto>.
+
+         This driver does not spin down disk drives (see the hdparm(8)
+         manpage ("man 8 hdparm") for that), and it doesn't turn off
+         VESA-compliant "green" monitors.
+
+         Generally, if you don't have a battery in your machine, there isn't
+         much point in using this driver and you should say N. If you get
+         random kernel OOPSes or reboots that don't seem to be related to
+         anything, try disabling/enabling this option (or disabling/enabling
+         APM in your BIOS).
