2081 | ---help--- | |
2082 | APM is a BIOS specification for saving power using several different | |
2083 | techniques. This is mostly useful for battery powered systems with | |
2084 | APM compliant BIOSes. If you say Y here, the system time will be | |
2085 | reset after a RESUME operation, the /proc/apm device will provide | |
2086 | battery status information, and user-space programs will receive | |
2087 | notification of APM "events" (e.g. battery status change). | |
2088 | ||
2089 | In order to use APM, you will need supporting software. For location | |
2090 | and more information, read <file:Documentation/pm.txt> and the | |
2091 | Battery Powered Linux mini-HOWTO, available from | |
2092 | <http://www.tldp.org/docs.html#howto>. | |

2094 | This driver does not spin down disk drives (see the hdparm(8) | |
2095 | manpage ("man 8 hdparm") for that), and it doesn't turn off | |
2096 | VESA-compliant "green" monitors. | |
2097 | ||
2098 | Generally, if you don't have a battery in your machine, there isn't | |
2099 | much point in using this driver and you should say N. If you get | |
2100 | random kernel OOPSes or reboots that don't seem to be related to | |
2101 | anything, try disabling/enabling this option (or disabling/enabling | |
2102 | APM in your BIOS). | |
