1858 APM is a BIOS specification for saving power using several different
1859 techniques. This is mostly useful for battery powered systems with
1860 APM compliant BIOSes. If you say Y here, the system time will be
1861 reset after a RESUME operation, the /proc/apm device will provide
1862 battery status information, and user-space programs will receive
1863 notification of APM "events" (e.g. battery status change).
1865 In order to use APM, you will need supporting software. For location
1866 and more information, read <file:Documentation/pm.txt> and the
1867 Battery Powered Linux mini-HOWTO, available from
1868 <http://www.tldp.org/docs.html#howto>.
1870 This driver does not spin down disk drives (see the hdparm(8)
1871 manpage ("man 8 hdparm") for that), and it doesn't turn off
1872 VESA-compliant "green" monitors.
1874 Generally, if you don't have a battery in your machine, there isn't
1875 much point in using this driver and you should say N. If you get
1876 random kernel OOPSes or reboots that don't seem to be related to
1877 anything, try disabling/enabling this option (or disabling/enabling
