-       ---help---
-         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).
