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). | |
1864 | ||
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>. | |

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 | |
