862 | APM is a BIOS specification for saving power using several different | ||
863 | techniques. This is mostly useful for battery powered laptops with | ||
864 | APM compliant BIOSes. If you say Y here, the system time will be | ||
865 | reset after a RESUME operation, the /proc/apm device will provide | ||
866 | battery status information, and user-space programs will receive | ||
867 | notification of APM "events" (e.g. battery status change). | ||
868 | |||
869 | In order to use APM, you will need supporting software. For location | ||
870 | and more information, read <file:Documentation/pm.txt> and the | ||
871 | Battery Powered Linux mini-HOWTO, available from | ||
872 | <http://www.tldp.org/docs.html#howto>. | ||
873 | |||
874 | This driver does not spin down disk drives (see the hdparm(8) | ||
875 | manpage ("man 8 hdparm") for that), and it doesn't turn off | ||
876 | VESA-compliant "green" monitors. | ||
877 | |||
878 | Generally, if you don't have a battery in your machine, there isn't | ||
879 | much point in using this driver and you should say N. If you get | ||
880 | random kernel OOPSes or reboots that don't seem to be related to | ||
881 | anything, try disabling/enabling this option (or disabling/enabling | ||
882 | APM in your BIOS). | ||
