1906 | APM is a BIOS specification for saving power using several different | |
1907 | techniques. This is mostly useful for battery powered systems with | |
1908 | APM compliant BIOSes. If you say Y here, the system time will be | |

1911 | notification of APM "events" (e.g. battery status change). | |
1912 | ||
1913 | In order to use APM, you will need supporting software. For location | |
1914 | and more information, read <file:Documentation/pm.txt> and the | |
1915 | Battery Powered Linux mini-HOWTO, available from | |

1924 | random kernel OOPSes or reboots that don't seem to be related to | |
