1980 ---help---
1981 APM is a BIOS specification for saving power using several different
1982 techniques. This is mostly useful for battery powered systems with
1983 APM compliant BIOSes. If you say Y here, the system time will be
1984 reset after a RESUME operation, the /proc/apm device will provide
1985 battery status information, and user-space programs will receive
1986 notification of APM "events" (e.g. battery status change).
1987
1988 In order to use APM, you will need supporting software. For location
1989 and more information, read <file:Documentation/pm.txt> and the
1990 Battery Powered Linux mini-HOWTO, available from
1991 <http://www.tldp.org/docs.html#howto>.
1992
1993 This driver does not spin down disk drives (see the hdparm(8)
1994 manpage ("man 8 hdparm") for that), and it doesn't turn off
1995 VESA-compliant "green" monitors.
1996
1997 Generally, if you don't have a battery in your machine, there isn't
1998 much point in using this driver and you should say N. If you get
1999 random kernel OOPSes or reboots that don't seem to be related to
2000 anything, try disabling/enabling this option (or disabling/enabling
2001 APM in your BIOS).
